PREFACE The purpose of this volume is to present to the Western world the biographies of leading Soviet scientists. This is done in an attempt to bring a better understanding on the part of the West of the outstanding achievements of the scientists of the East. It is further hoped that this volume will facilitate a scientist to scientist contact and thereby lead to fruitful individual collabor- ation. The material presented has been obtained from sources scat- tered throughout Soviet literature. A copy of the manuscript was sent to the President of the Soviet Academy of Sciences three months before presenting it to the publisher. Individual biogra- phies were sent to the Soviet scientists for approval or for cor- rection. Unfortunately, the Academy was not able to check on the manuscript. On the other hand, many Soviet scientists have graciously corrected their biographies. For this we are thank- ful. This work was facilitated in its early stages by Professor George Krugovoy, William Causey, Valentina Kaye, Olga Plos- chek, Boris Sovetov.

S. Alexandroff was born May 7, 1896. In 1917 he gradu- ated from Moscow University. He became a lecturer in 1921 and in 1929 was made professor. In 1921 he was elected a member of the Moscow Mathematical Society, in 1932 Presi- dent, and in 1946 an Honorary Member. He has been a Corre- sponding Member of the U.S.S.R. Academy of Sciences since 1929 and since 1953 an Academician. Alexandroff is a member of the Berlin Academy of Sciences (Associate Member since 1950), the American Philosophical Society in Philadelphia, the National Academy of Sciences in Washington (since 1947), the ALEXANDROFF 8 Gottingen Academy of Sciences (1929-38, and from 1945), the Polish Academy of Sciences and other societies. In 1943 he was awarded a Stalin Prize. Alexandroff investigated the theory of point sets and the theory of the function of the real variable, obtaining such im- portant results as the proof of the theorem on the power of Borel sets. In collaboration with P. S. Urysohn he developed in the Soviet Union the field of topology, becoming the head of the U.S.S.R. School of Topology. Among his former students are: L. Pontryagin, A. Tychonoff, A. Kurosh, Yu. Smirnov, G. Chogoshvili, K. Sitnikov and others. Alexandroff originated one of the main theories of topological spaces—the theory of bi- compact spaces. He also contributed in an essential way to the modern theory of dimensionality (in particular he founded the theory of the homogical dimension); he was the founder of methods based on combinatory algebraic investigation of sets and spaces of a general nature; he proved a series of basic "laws of duality" (combining topological properties of the geo- metrical figure with topological properties of space comple- mentary to it).

In 1931 he gradu- ated from Leningrad Polytechnical Institute. He had been on the staff of the Physico-Technical Institute of the U.S.S.R. Academy of Sciences since 1927 and became the Director of its Power Engineering Laboratories. In 1939 Alikhanov was elect- ed a Corresponding Member of the U.S.S.R. Academy of Sciences and in 1943 an Academician. He has also been a member of the Armenian S.S.R. Academy of Sciences since 1943. In 1941 and 1948 he was a recipient of Stalin Prizes. The first scientific investigations of Alikhanov were in the field of x-rays. In 1934 in collaboration with his brother, Artemii Isaakovich Alikhan'yan, he began research in radio- activity, and in the same year, jointly with M. S. Kozodaev and Alikhan'yan, discovered the pair emission by excited nuclei. In 1935, together with Alikhan'yan, he formulated the relation- ship between j3- spectra and the atomic number of the element. In 1936, with Alikhan'yan and L. A. Artsimovich, Alikhanov proved experimentally the conservation of momentum during pair annihilation. Investigations of cosmic rays (1939) led Alikhanov, together with A. I. Alikhan'yan and S. Ya. Nikitin, to the discovery of unstable mesons. In 1949, he built the first reactor in the U.S.S.R., using heavy water as a moderator. At present Alikhanov is working on the development of nuclear reactors. As of 1961, Alikhanov was Director of the Institute of Theo- retical and Experimental Physics and is Chairman of the Com- mission on Cosmic Rays. Bibliography : and A. I. Alikhan'yan.

I. Alikhan'yan was born July 24, 1908. He graduated from Leningrad University in 1931 and began, with A. I. Alikhanov, work in nuclear physics and cosmic rays. Since 1943 he has been an Academician of the Armenian SSR Academy of Sciences and since 1946 a Corresponding Member of the U.S.S.R. Acade- my of Sciences. In 1941 and 1948 he was awarded Stalin Prizes. From 1934, Alikhan'yan, with A. I. Alikhanov and M. S. Kozodaev, discovered pair emission by excited nuclei. In 1935, Alikhan'yan, with Alikhanov, established the law of the de- pendence of beta-spectra on the atomic number of the element. The main work of Alikhan'yan is devoted to the study of cosmic rays. In association with Asatiani, he discovered showers with few particles in cosmic rays (the so-called narrow showers). Alikhan'yan also showed that in the composition of primary components of cosmic radiation there are particles present with energies up to LQI'^ electron-volts. In 1945 Alikhan'yan helped establish a cosmic ray station on Mountain Aragats, where he, with associates, conducted a magnetic analysis on the mass of cosmic ray particles. In 1951-52 Alikhan'yan and his associates were successful in separating particles with a mass ~ 200me in cosmic rays and also in obtaining some indication of the existence of parti- cles with masses of approximately 600me and 950me. As of 1961, Alikhan'yan was Director of the Armenian Academy of Sciences Institute of Physics. Bibliography: and A. Dadayan.

Ambartsumian was born September 18, 1908 in Tbilisi in the family of the distinguished Armenian philologist, writer and teacher, A. A. Ambartsumian. Ambartsumian received his secondary education at Tbilisi. He graduated in 1928 from Leningrad University, having published, as a student, more than ten papers on theoretical astrophysics and mathematics. He pursued graduate studies at Pulkovo Observatory under the Russian astrophysicist, A. A. Belopolskii (1854-1934). As a graduate student, he published papers dealing with solar phy- sics, the physics of the stellar atmospheres and gaseous nebu- lae, and theoretical physics. He completed his graduate work in 1931, served as docent at Leningrad University, and in 1934 became a professor. Ambartsumian established the chair of Astrophysics at Leningrad University in 1934, and occupied it until 1946. He became Director of the Leningrad University Astronomical Observatory in 1938. He has been a pro-rector of science at the Leningrad University. From 1943 to 1947 he was Vice-President of the newly organized Academy of Sciences of the Armenian S.S.R. He was head of the research branch of the Leningrad University which was moved to Yelabuga during World War II. Since 1944 he has served as the Director of Yerevan Observatory. On his own initiative, he began and supervised the planning and construction of Byurakan Observa- tory in 1946, and became the Director. He has held the Chair of Astrophysics at Yerevan State University since 1947. He became a member of the Communist Party of the Soviet Union in 1940. In 1947, he was elected President of the Academy of Sciences of the Armenian S.S.R. From 1948 to 1955, he was Vice President of the International Astronomical Union. He was elected Academician of the Academy of Sciences of the U. S.S.R. in 1953, having been a Corresponding Member since 1939. He is a Deputy of the Supreme Soviet, since 1950, a member of the Central Committee of the Communist Party of Armenia, and President of the Armenian Society for the Propa- gation of Scientific and Political Knowledge. He has frequently participated in the work of international congresses, confer- ences, and meetings, and is an honorary member of corre- sponding member of academies of science and scientific socie- ties of Austria, Britain, Belgium, Canada, France, Germany, AMBARTSUMIAN 14 and the United States. Ambartsumian has twice received a State Prize, in 1946 and in 1950. He has also received two Orders of Lenin and two Orders of the Red Banner of Labor. In 1961 in Berkeley (USA) V. A. Ambartsumian was elected the President of the International Astronomical Union. The early works of Ambartsumian dealt with the study of stellar physics and gaseous nebulae. He has gi'^^en a mathemati- cal interpretation of the complex physical processes involved i-n the luminescence of gaseous nebulae; he has demonstrated the important role of 'L<^' radiation pressure in the nebulae, has developed a solution to the problem of atom accumulation in metastable states, and has elaborated a method for determin- ing the electron temperature of the nebulae. The method he worked out for subdividing the 'Lc' and 'LqI fields of radiation has enabled him to devise a theory of radiation equilibrium of planetary nebulae. This theory has been the foundation for all subsequent studies in this direction, the most valuable of which is the research conducted by his student, V. V. Sobolev. Am- bartsumian has also devised methods of determining the masses of the nebulae and the gaseous envelopes surrounding the stars. These studies have stimulated further research on stellar physics and nebulae both in the Soviet Union and abroad. He was the first in the Soviet Union to have organized a course in Leningrad State University on theoretical astrophysics and is the leader of the Soviet school of theoretical astrophysics. More recently Ambartsumian' s interests extended to include stellar astronomy and cosmogony. A large number of his studies deal with the problem of the evolution of stellar sys- tems. The idea underlying these studies is that of the existence of irregular forces in addition to regular forces in stellar systems. In the case of the double stars and star clusters, these irregular forces often play a decisive role in the process of their development. In order to solve this problem, he elabo- rated new methods of statistical mechanics of stellar systems and successfully applied them to dual stars and star clusters. The results of these investigations were incorporated by him into lectures during the 1930' s at Leningrad University. These investigations and other results have affected previously exist- ing theories of the age of the Galaxy and of the evolution of its component systems. Ambartsumian refuted the "Long Time Scale,'' according to which the age of the Galaxy was taken to be roughly lO^^ years, while, according to him, the age of the Galaxy is in the order of 10^0 years. During 1941-43, he personally conducted extensive research on the theory of light 15 AMBARTSUMIAN diffusion in a turbid medium, which is of great importance in many questions of geophysics, physics, and astrophysics, and for which he received the State Prize in 1946. This traditionally well-known problem in science has generally been reduced to an integral equation for which the solution was found in a very cumbersome fashion by means of consecutive approximations. Ambartsumian applied an entirely new method to the solution of this problem: reducing it to simple functional equations, he ob- tained an exact solution to it. These equations have become known as "Ambartsumian' s Functional Equations." Also in the forties, he completed a cycle of studies dealing with the problem of the structure of the Galaxy which had been partially carried out during his stay in Leningrad. The structure of the Galaxy (the basic problem of modern Astronomy) became a more com- plex question in the 1930' s with the discovery of dark, light- absorbing matter in the interstellar space. In studying (along with Sh. G. Gordeladze) the distribution of hot stars and of dif- fuse nebulae, Ambartsumian revealed the patchy structure of the dark matter, and drew the conclusion that interstellar ab- sorption is conditioned by the total mass of dark clouds, in the form of separate, obscure nebulae, not a continuous medium, as had been previously believed. On the basis of the patchy structure of the dark matter, he elaborated a mathematical theory of the fluctuations in the distribution of the stars, of the brightness of the Milky Way, and of the extragalactic nebulae which was subsequently developed in the work of Ambartsumi- an's pupils and by a number of foreign scientists (such as Chandrasekar, Munch). His work also dealt with the relation- ship between the luminosity of interstellar matter in space and the neighboring stars, a method to calculate the mass ejected by Nova (the order of magnitude of only one part in a thousand of the mass of the sun), a theory on radiation equilibrium in planetary nebulae, and a theory for determining the space ve- locity distribution of stars from their radial velocities. A new development of Ambartsumian is concerned with the origins and development of celestial bodies. An analysis and synthesis of observation material accumulated enabled him in 1947 to discover the existence in the Galaxy of a new type of stellar systems which he designated as stellar associations. These he found to be subject to break-up through the dropping out of individual stars, and to be of comparatively recent origin (State Prize, 1950). He established the continuous process of star formation at the present stage in the development of the Galaxy. This was a refutation of the concept held of the AMBARTSUMIAN 16 simultaneous origin on the stars in the Galaxy. This work pro- vided a foundation for research in astronomy into the evolution of stars and stellar systems by observation of their develop- ment. The theoretical prediction (in 1947-49) by Ambartsumian concerning the dynamic instability of stellar associations and their expansion was confirmed as a result of the analysis of movements of stars carried out in Leyden and Byurakan. Ambartsumian' s finding of the group character of the emergence of stars has permitted clearer study of the physical nature and cosmogonic role of double and multiple stars, star chains and clusters, and gaseous nebulae. It has also resulted in work by Ambartsumian on continuous emission, another as- pect of the physical nature of the members of stellar associ- ations. Continuous emission is the excess radiation in a total spectrum observed in stars of the T Tauri and UV Ceti type and also in comet-like nebulae. By synthesis and analysis of unco- ordinated data, Ambartsumian established the non-thermal character of continuous emission. This aroused great interest in the origin of this entirely new phenomenon. At the present time, extensive study of continuous emission is under way both at the Byurakan Observatory and at a number of foreign ob- servatories (Lick, Tonantzintla). In recent years, Ambartsumian began research on the galaxies and on the systems constituted by them. One result of his work is the conclusion (based on the group character of the formation of galaxies) that galaxies form as multiple systems and clusters having in many cases positive energy, that is, constituting systems under disintegration. He interprets radio- galaxies as the result of a process of division—the formation of galaxies counterbalancing the hypothesis of collision of galaxies. The blue galaxies detected by him, a particular kind of dwarf galaxies, enrich our conceptions of the nature of galaxies and may furnish much valuable material for studying the evolution of galaxies. The very important role of nuclei of galaxies in their evolution was shown. In particular it was concluded that the nuclei of galaxies display a number of forms of cosmogonic activity. In 1960 the composition of degenerate gas with nuclear densi- ty and greater was studied. It was shown that with increasing density, different hyperons successively appear and their number in the gas increases. They should be stable due to the Pauli principle. Then it is proved that in the case of the degenerate super- dense gas the configuration of gravitational equilibrium of 17 AMBARTSUMIAN cosmic mass should consist of a hyperon nucleus, neutron layer and outer envelope of usual composition (electrons, protons, and composite nuclei). The internal structure of equilibrium configurations of stel- lar masses, with densities of the order of the atomic nucleus and higher, was studied. It was shown that the space metrics inside the configuration essentially deviates from the Euclidian type. As of 1961, Ambartsumian was a member of the Presidium U.S.S.R. Academy of Sciences, and Chairman of the Commission on Astrophysics of the U.S.S.R. Academy of Sciences. Bibliography: Uber eine frage der eigenwerttheorie. Z. f. Phys., 1929, #53.

Arbuzov was born August 30, 1877. He graduated from the Kazan University in 1900 and from 1911 to 1930 was a pro- fessor there. He had been a student of A. M. Zaitsev (1841- 1910, an outstanding organic chemist and Corresponding Mem- ber of the Petersburg Academy of Sciences). In 1930 he be- came a professor at the Kazan Chemical-Technological Institute. Arbuzov was elected a Corresponding Member of 23 ARBUZOV the U.S.S.R. Academy of Sciences in 1932 and an Academician in 1942 and was made President, in 1945, of the Kazan' Branch of the U.S.S.R. Academy of Sciences. He was a delegate from R.S. F.S.R. to the Supreme Soviet of the U.S.S.R. for the second through fifth meetings and again as of March 18, 1962. In 1957 he was a Hero of Socialist Labor. Twice, 1943 and 1947, he has won Stalin Prizes. Arbuzov's studies are concerned with phosphorous-organic compounds. In his master's degree thesis "Structure of Phosphorous Acid and its Derivatives" (1905), Arbuzov de- termined the structure of phosphorous acid and its esters. He found a catalytic rearrangement reaction for intermediate esters of this acid, which is called the Arbuzov Rearrangement. This isomerization is the widely used method for synthesizing alkylphosphenic acids and similar compounds. In his doctor's degree thesis "Catalysis in Conversion of Some Phosphorous Compounds" (1914), he extended his theory to cover phenyl- phosphenic and other esters. He identified the forces which accelerate the catalytic isomerization processes, with the forces which affect the rates of conventional chemical reactions. Together with his pupil A. A. Dunin, Arbuzov synthesized phosphonacetic ester and its homologs. The sodium and po- tassium derivatives of these esters can be used in syntheses similar to the acetoacetic and malonic ester. This synthesis and investigation is related to Arbuzov' s work on tautomerism of dialkyl esters of phosphorous acid and on the reactions of their metal derivatives. During the investigation of these com- pounds Arbuzov, in collaboration with B. A. Arbuzov, found a new method of obtaining free radicals of the triarylmethyl series. Arbuzov has also studied the tapping and flow of soft gums from conifers. He found a high pressure (2 to 3 atmos- pheres) in the gum ducts of these plants and developed a tech- nique for collecting gums without any loss of volatile substanc- es. This technique aided the rapid growth of the resin industry of the U.S.S.R. Arbuzov wrote a book on the history of chemis- try which showed the contributions of N. N. Zenin, A. M. Butlerov, the Kazan' school as a whole, M. V. Lomonosov, D. I. Mendeleev, S. V. Lebedev and others. He also studied extensively the history of free radicals, phosphorous -organic compounds, and catalysis. As of 1961 he was Chairman of the Commission on the History of Chemistry, and Member of the Presidium of the U.S.S.R. Academy of Sciences.

He was appointed professor at the Moscow Aviation Institute in 1941. Beginning in 1937, he directed the Laboratory of Dynamic Machines of the Institute of Machine Control of the U.S.S.R. Academy of Sciences. From 1942 to 1954, Artobolev- skii was Acting Secretary of the Department of Technical Sciences of the U.S.S.R. Academy of Sciences. He was Chair- man, 1945-1954, of the Department of Mechanical Engineers. In 1939 he was elected a Corresponding Member of the U.S.S.R. Academy of Sciences, and in 1946 an Academician. Artobolev- skii was an Honored Scientist of the R.S.F.S.R. in 1945. In 1946, the Academy of Sciences awarded him, jointly with V. V. Dobrovolskii and Z. Sh. Blokh, the P. L. Chebyshev Prize for the treatises, A Synthesis of Mechanisms (1944) and The Scien- tific Legacy of Chebyshev (1945 with N. I. Levitskii). He is also active in public affairs and in 1947 was made Acting Chair- man of the All-Union Department for Dissemination of Political and Scientific Knowledge. Artobolevskii' s field of activity is the theory of machines and mechanisms. He worked out a classification of three ARTSIMOVICH 26 dimensional mechanisms and developed new methods for their kinematic analysis. He wrote the first Russian monograph on spatial mechanisms (The Theory of Spatial Mechanisms, 1937). He developed new methods for kinematic analysis of complicat- ed multi -element mechanisms (1939). With a group of Soviet scientists, he originated methods for the study of modern auto- matic machines, especially in the food, printing, and machine- tool industries. He has been working on the theoretical and experimental methods for studying the dynamics of working machines. Bibliography: Theory of Three Dimensional Mechanisms. Moscow- Leningrad: 1937.

Artsimovich, son of a Moscow professor of statistics, was born February 25, 1909. He graduated at an early age from the Belorussian State University; and at the age of 21, he began to woik in the Leningrad Phy si co- Technical Institute where he 27 ARTSIMOVICH was a student of A. F. loffe (1880-1960, internationally known physicist), the Director. He also taught at the Leningrad Poly- technical Institute and at Leningrad University. In the postwar years, he gave courses on atomic and nuclear physics, first at the Moscow Engineering and Physics Institute, then more recently at the Moscow University. In 1946 Artsimovich was elected a Corresponding Member and in 1954 an Academician of the U.S.S.R. Academy of Sciences. He was awarded a Stalin Prize in 1953, and in 1958 a Lenin Prize. He has also received a number of orders of the Soviet Union from the government. Artsimovich' s first researches were in x-ray optics, par- ticularly on the problem of complete x-ray reflection. This investigation was carried out together with A. I. Alikhanov. In 1934-1935 Artsimovich, together with I. V. Kurchatov and others, studied the properties of the neutron and in particular the proton capture by a neutron. This study showed that the capture cross section of slow neutrons by protons is very great. In 1936, Artsimovich, with A. I. Alikhanov and A. I. Alikhanyan, examined the conclusions of the American physicist Shenkland on the possibility of the violation of the laws of conservation in the Compton Effect. An original experiment was set up which confirmed the validity of the laws of conservation in the electron and positron annihilation and refuted the ideas of Shenkland. The main subject of his research at the Leningrad Physico- Technical Institute has been the study of the processes of the interaction of fast electrons with matter. In the mid thirties experimental data on bremsstrahlung and the angular distri- bution of electrons diverged from accepted theory by two orders of magnitude. Artsimovich did extensive experiments on the dependence of the bremsstrahlung intensity and the total energy losses on the energy of incident electrons. A careful analysis of the results showed that the quantum -mechanical theory of the passage of fast electrons through matter agrees with ex- perimental data within the accuracy of the experiment. During the war years (1943-46) Artsimovich was concerned with electron optics and the theory of chromatic aberrations of the electron optical system; he carried out theoretical and ex- perimental research in the field of electron optical converters. In 1945, Artsimovich and I. Ya. Pomeranchuk did theoretical research on the role of radiation losses in the betatron. This work permitted the establishment of the maximum energy achieved by this type of electron acceleration. Artsimovich was one of a group who developed an electromagnetic method of isotope separation. From currents then available in the ARTSIMOVICH 28 mass spectrometer laboratory (of the order of 10-10 amperes), it was necessary to use currents of the order of an ampere. In reaching a solution to this problem, Artsimovich carried out a careful analysis of the problems of the aberrationless focussing of ion beams in axially -symmetric magnetic fields. He de- signed the optics of the ion source. As a result of this work, the Soviet physicists developed a successful production of sepa- rated isotopes. In the beginning of the fifties, Artsimovich be- gan his work on a controlled thermonuclear reaction. The group of physicists under Artsimovich began the study of high current pulse discharge in evacuated deuterium. In the course of these experiments, the group succeeded in obtaining for a short time a highly ionized plasma of a million degrees. In 1952, this group of scientific workers discovered that a power- ful pulse discharge in deuterium at low pressure is a source of neutrons and x-ray radiation of short wave length. Further studies showed that the gas-discharge plasma, compressed in the presence of the longitudinal magnetic pole possessed para- magnetic properties. It was also shown that neutrons originate, not as a result of the thermonuclear reaction, but as a result of a specific acceleration process. The work of studying the means of obtaining a controlled thermonuclear reaction is now being conducted extensively under Artsimovich' s direction. The report of L. A. Artsimovich at the Second World Confer- ence on the Peaceful Use of Atomic Energy in Geneva in September, 1958, is a survey of the studies of Soviet physicists in this field. Artsimovich has participated in the Pugwash Conferences. As of 1961, he was Secretary of the Physical Mathematical Sciences Department of the U.S.S.R. Academy of Sciences. Bibliography: and A. I.

Pavlov, he graduated from the Agricultural Institute in 1926 and from the University of Yerevan Medical School in 1930 From 1930 to 1938, he worked in the Physiological Institute, Academy of Sciences. From 1935 to 1941, he worked at the Bekhterov Cerebral Institute and from 1936 to 1941, at the Leningrad Institute of Pedagogy where he became a professor in 1938. From 1950-52, he was Director of the Institute of Higher Neuroactivity. In 1944 he was appointed Chief of the Academy of Sciences Physiological Laboratory, and later be- came Director of the Institute. He has been professor at the Second Medical Institute since 1950. He has been an Acade- mician of the Armenian Academy of Sciences since 1947, a member of the Communist Party of the Soviet Union since 1929, and was elected to the U.S.S.R. Academy of Sciences as a Corresponding Member in 1939. As of 1961, he was Director of the Institute of Neurophysiology of the U.S.S.R. Academy of Sciences. In 1962 he was awarded the Pavlov Gold Medal for studies in Pavlovian physiology. Using Pavlov's teachings of the evolutionary theory of the adaptability of the nervous system, Asratyan explained the re- generating aspects in a damaged organism. He and his collabo- rators proved that in the regeneration of lost and broken functions of the damaged organism, a deciding role is played by the cortex of the large hemispheres of the cephalic brain. He also demonstrated the pathological condition of the organism, produced by organic trauma (traumatic shock, paralysis, in- cisions) and offered a new soporific method for treatment of these conditions. An anti- shock liquid developed by Asratyan was used in the front lines of the second World War. He, with collaborators, has been working on the problems of cortical presentation of unconditioned reflexes, the transfer into con- ditioned reflex activity, and the relationship of conditional ties to various functional properties.

N. Bakulev was born December 7, 1890. He graduated from the Medical Faculty of Saratov University in 1915 after which he served for three years as a regimental physician. From 1919 to 1926 Bakulev was at the hospital surgical clinic of Saratov University, first as a hospital surgeon and later as a clinical assistant. He worked, in 1926 to 1943, at the Surgical Clinical Faculty of the Second Moscow Medical Institute where BAKULEV 34 he became a professor in 1935. In 1943 he was head of the Surgical Clinical Faculty of the Pediatric Faculty at the Second Moscow Medical Institute, and as of 1962 has been Chairman of the Surgical Clinical Faculty of the Therapeutic Faculty. During World War II he was a front-line surgeon and subse- quently chief surgeon of the Moscow Evacuation Hospital and chief of the surgical division of the Kremlin Therapeutico- Sanitation Administration Hospital. Bakulev was elected Corresponding Member of the U.S.S.R. Academy of Medical Sciences in 1947, and in 1948 Active Member. In 1958 he was made Academician of the U.S.S.R. Academy of Sciences. In 1954 and in 1957, he was elected President of the U.S.S.R. Academy of Medical Sciences. He was a Deputy to the Supreme Soviet of the U.S.S.R., third to fifth convocations. Bakulev was an Honored Scientist of the R.S-F.S.R. in 1947. He was award- ed a State Prize in 1949, and in 1957, and two other times Lenin Prizes. In 1960 he was made a Hero of Socialist Labor. Bakulev conducted detailed studies on kidney function during ureter transplantation and worked in the field of bone surgery, tumors of the posterior mediastinum, and lungs. At the Moscow Clinic, he studied encephalography and ventriculography and was one of the first to introduce these methods in clinical research in the U.S.S.R. He has also proposed the treatment of brain abscesses by puncture (his doctoral dissertation). During the second World War he studied the treatment of firearms wounds, including spinal cord wounds and cranium damage with exposed tissue where he proposed a closed suture method. After the war Bakulev turned to thoracic surgery problems in lung and heart operations, and in 1948 performed the first operation in the U.S.S.R. on a congenital defective heart. In 1956 Bakulev initiated the organization of the Institute of Thoracic Surgery in Moscow, which in 1960 was reorganized into the U.S.S.R. Academy of Medical Sciences Institute of Cardiovascular Surgery. He organized scientific research in acquired and congenital diseases of the heart and main vessels, developed surgical methods for their treatment, and incorpo- rated these methods into medical practice (Stalin Prize 1957).

A. Balandin was born December 8, 1898. In 1923 he graduated from Moscow University and worked there from 1927, becoming a professor in 1934. He organized the first labora- tory course in the Department of Organic Catalysis at Moscow State University and in 1959 became Director of the Department. Balandin is the Chief of the Laboratory of the Kinetics of Cata- lytic Organic Reactions and the N. D. Zelinskii Laboratory of the Institute of Organic Chemistry of the Academy of Sciences of the U.S.S.R. He is a student of N. D. Zelinskii (1861-1953, an outstanding organic chemist specializing in catalysis and stereoisomerism.) Balandin has been active in scientific organizations; he is the Chairman of the Council for the Prob- lem "Scientific Bases of Selecting Catalysts" in the Chemical Sciences Section of the U.S.S.R. Academy of Sciences. This BALANDIN 36 Council coordinates all work on catalysts in the U.S.S.R. In 1949 Balandin became a member of the Communist Party of the Soviet Union. He was elected Corresponding Member of the U.S.S.R. Academy of Sciences in 1943 and Academician in 1946. He has received the Order of Lenin, two Orders of the Red Banner of Labor, and a Stalin Prize. For his research in synthetic rubber he was awarded the Mendeleev and Lebedev Prizes. Balandin formulated the so-called multiplet theory of cataly- sis, attempting to establish a relationship between the geometry of the atomic groups, which change directly in catalysis during a reaction, and the geometry of active centers on the surface of the catalyst. On the basis of his theory and classification, Balandin studied the dehydrogenation of paraffins, olefins, alkylbenzenes, and those products of dehydrogenation which are important for the industrial synthesis of monomers, for obtain- ing synthetic rubber and other high-polymers. Balandin is a Soviet pioneer in the study of the kinetics of organic catalytic reactions. He deduced the general kinetic equation for monomolecular reactions in a flow system. Balan- din and his associates carried out extensive research on the kinetics of the dehydrogenation of hydrocarbons, the dehydro- genation and dehydration of alcohols, and the dehydrogenation of amines. Using the method of tagged atoms, the kinetics and mechanism of the dehydration of ethyl alcohol on aluminum oxide and the kinetics of the dehydrogenation of butane and butylene were studied. The reactions of catalytic production of styrene and its homologs were investigated in detail. This study is of great importance for synthetic rubber and plastics. Balandin formulated the theory of the hydrogenation of unsatu- rated compounds. The multiplet theory proved useful in the studies of Balandin and his co-workers on the hydrogenation of polysaccharides to obtain polyatomic alcohols. It received con- siderable development with the discovery of the laws for the selection of catalysts. The following are members of his scientific school: Ye. A. Agronomov, O. K. Bogdanova, A. Kh.

Baranskii was born July 26, 1881. In 1901, he was expelled from Tomsk University for participating in a student political strike. Since that time, he became a professional revolutionary. In the fall of 1905, he was chosen as a delegate of the Siberian Bolsheviks to the Irkutsk Conference of the Siberian Social Democratic Union. He graduated from the Moscow Commercial Institute in 1914. In 1915, he was a board member of the People's Commissars of Worker -Peasant In- spection. In 1918, he began to study economic geography which arose in opposition to the then predominant statistical branch method. He has been awarded the title Honored Scientist of the R.S.F.S.R. in 1943. In 1939 he was elected to the U.S.S.R. Academy of Sciences as a Corresponding Member. He is a member of the Communist Party of the Soviet Union. Baranskii considers the main object of investigations in economic geography to be not the branches of economics but economic regions. In economic-geographic studies of various countries he stresses the internal space difference; he placed BARANSKII 38 stress on the economic division into districts and the charac- teristics of these districts. In this connection, he placed great importance on economic maps and field economic-geographic investigation of territories. Baranskii compiled a series of textbooks on economic geography of the U.S.S.R. (among them, a standard textbook for the eighth grade which until 1955 had 16 editions). He established a series of university courses. He is the author of questions of methodology of economic geography and cartography. In March 1962, Baranskii was awarded the Hero of Socialist Labor.

Bernshteyn was born March 6, 1880 in Odessa. He did graduate work in the Sorbonne in 1899 and also at the Paris Higher Electrical Engineering School in 1901. In 1904 he re- ceived the Doctor of Mathematical Science in Paris and in 1914 the Doctor of Pure Mathematics at POiarkov. From 1907 to 1908 Bernshteyn was professor at the Petersburg Women's Poly technical School and from 1908 to 1918, professor at the Higher School for Women at Kharkov. He taught at Kharkov University from 1907 to 1933 and in 1920 became a professor there. He was a professor at the Leningrad Polytechnical Insti- tute during 1933-1941 and about the same time, 1934-1941, at Leningrad University. In 1935 he joined the staff of the Mathe- matics Institute of the U.S.S.R. Academy of Sciences. Bern- shteyn was elected a Corresponding Member of the U.S.S.R. Academy of Sciences in 1924, and in 1929 an Academician. Since 1925 he has been a member of the Ukrainian Academy of Sciences. He was made an Honorary Member of the Moscow Mathematical Society in 1940. In 1955 he became a Foreign Member of the Paris Academy of Sciences. He was awarded in 1941 a Stalin Prize. Bernshteyn' s scientific work deals chiefly with the theory of differential equations, and the theory of approximations by poly- nomials of functions. Early investigations (1903) of second order equations of the elliptical type led him to the conclusion that under certain general conditions their solutions become analytical functions which can be represented as a power series. Bernshteyn developed a new method of solving elliptical differ- ential equations. He also studied the functional approximation of polynomials, further developing the theory proposed by P. L. Chebishev and continued by the scientists of the Petersburg School. This work establishes the accuracy with which a function can be approximated by polynomials of different powers and by differential functional properties (as for instance through derivatives of a definite order). Bernshteyn, with his students, created a new branch in the theory of functions, which he called "the constructive theory of functions." His contri- butions in the field of probability are: the establishment of an axiomatic structure of the theory of relativity (1917); investi- gations of finite theorems (continuation and completion of the work of A. A. Markov, Sr. and A. M. Lyapunov); study of sto- chastic differential equations and the practical application of the theory of probability to solutions of problems in physics and statistics. 49 BERNSHTEYN Bibliography: Collection of Papers, 1, 2.

Blinova was born December 7, 1906. She graduated from North Caucasus University (Rostov -on-the -Don). In 1935 to 1945, she was senior scientific research associate at the Main Geophysical Observatory. In 1943 she began working at the Central Institute of Weather Forecasting in Moscow. Since 1953 she has been a Corresponding Member of the U.S.S.R. Academy of Sciences. Continuing the work of N. E. Kochin (1901-1944, mathema- tician), Blinova investigated in detail the conditions of atmos- pheric front stability (1936). Later, from 1938, she studied the general circulation of the atmosphere and developed a theory of radiative equilibrium in the atmosphere. She was successful in making a quantitative explanation of the existence of the so- called centers of atmospheric action. For this, she studied wave disturbances occurring in the general east-west atmos- pheric flow. She utilized the same wave method for a quanti- tative analysis of such atmospheric macroprocesses as the origin and development of cyclines and anti-cyclones. Blinova indicated in her works methods of long-term weather forecast- ing by means of integration of the so-called vortex equations proposed by A. A. Fridman (1888-1925, physicist), which are widely utilized at the present time for weather forecasting with the aid of electronic computers and for solving other problems in atmospheric dynamics.

Bochvar (1870-1947, founder of the school of metallurgists). In 1923 he graduated from the Moscow Higher Technical School and then taught there. He began teaching at the Moscow Institute of Non- Ferrous Metals and Gold in 1930, and in 1934 he became a pro- fessor. In 1939 Bochvar was elected Corresponding Member of the U.S.S.R. Academy of Sciences and in 1946 Academician. He is a Hero of Socialist Labor and a recipient of a Stalin Prize. Bochvar' s basic studies are concerned with the kinetics of eutectic crystallization (doctoral dissertation, 1935), the re- crystallization of metals and alloys, the deformation of alloys at high temperatures, the crystallization of alloys under pres- sure and the relation of the casting properties of alloys to their phase diagrams. Having carried out experimental research in the mechanism of eutectic crystallization, Bochvar constructed a theory for structural peculiarities and anomalies of alloys. He established the temperature patterns of the crystallization of metals and alloys (the so-called "Bochvar Rule"), and formu- lated the principles of a structural theory of heat-resistance. Studies on the crystallization of alloys under pressure permit- ted him, jointly with A. G. Spasski, to develop new industrial methods of shaping castings by crystallization under pressure. 55 BOGOLYUBOV thus eliminating porosity of aluminum alloys, and to work out new principles of casting, ensuring significant metal reduction. Bochvar wrote a series of textbooks on metallography and the thermal treatment of metallic alloys. Bibliography: A Study of the Mechanism and Kinetics of Crystallization of Eutectic Alloys.

Bogolyubov was born in 1900 in Nizhnii Novgorod (now Gorkii) and in 1922, he moved with his mother to Kiev, where he attracted the attention of mathematicians D. A. Grave and N. M. Krilov. In 1923 he began work in a seminar sponsored by the department of mathematical physics of the Academy of Sciences of the Ukrainian S.S.R. under the direction of N. M. Krilov. In 1924, he wrote his first scientific paper. In 1925, by special permission, he was admitted with no diploma from a higher educational institution as an associate of the department of mathematical physics of the Academy of Sciences of the Ukraini- an S.S.R. In 1928, he defended his candidate's dissertation on the subject "The Use of Direct Methods in the Calculus of Vari- ations for Investigation of Irregular Cases of the Problem of the Extreme." In 1930, the Presidium of the Academy of Sciences of the Ukrainian S.S.R. awarded him the degree Doctor of Mathematics honoris causa. Starting in 1928, Bogolyubov was employed by the Academy of Sciences of the Ukrainian S.S.R. In 1936, he became chair- man of a department, first at Kiev University, and in 1959 at Moscow University. From 1946 to 1949, he was Dean of the Mechanics and Mathematics Division of Kiev University; he was chairman of a number of departments of the Academy of Sciences U. S.S.R. (Department of Nonlinear Mechanics of the Institute of Structural Mechanics, Department of Mathematical Physics of the Institute of Mathematics). Since 1956, he has been in charge of the Department of Theoretical Physics of the Mathematics Institute imeni V. A. Steklov of the Academy of Sciences U. S.S.R., as well as of the Laboratory of Theoretical BOGOLYUBOV 56 Physics of the Joint Institute of Nuclear Research in Dubno. He established the School of Nonlinear Mechanics in Kiev and the School of Theoretical Physics in Moscow. These schools have made a great contribution both to the development of theo- retical science and to the solution of numerous practical prob- lems of modern physics and engineering. Bogolyubov has been invited many times to deliver lectures on his research at foreign universities and scientific research institutes, as well as at international congresses and conferences. A number of his monographs have been translated into foreign languages. In 1939, Bogolyubov was elected Corresponding Member of the Academy of Sciences of the Ukrainian S.S.R., in 1947 Corre- sponding Member of the Academy of Sciences U.S.S.R., and in 1948 an Academician of the Academy of Sciences of the Ukraini- an S.S.R. In 1953, he was elected Academician by the Academy of Sciences U. S.S.R. He received an honorary doctorate from the University of Hyderabad. For his research in the field of nonlinear mechanics and statistical physics, set forth in the monographs, "On Some Statistical Methods in Mathematical Physics," and "Problems of Dynamic Theory in Statistical Physics," Bogolyubov received in 1947 a Stalin Prize, First Class. For his investigation in superconductivity, he was awarded the Lomonosov Prize in 1957. In 1958, he was award- ed the Lenin Prize for working out the new methods in quantum field theory and in statistical physics which had led, in particu- lar, to substantiation of the theory of superfluidity and the theory of superconductivity. Other awards he has received in- clude another Stalin Prize and seven orders, among them three Orders of Lenin and the Order of the Red Banner of Labor. The scientific activity of Bogolyubov, which has extended over more than 30 years, covers varied fields of analysis, function theory, differential equations, theory of vibrations, theory of stability, and quantum field theory. During the period of his productive scientific inquiry, he published over 170 scien- tific papers, including a series of fundamental monographs. The following is a brief outline of the principal lines of his work. His earliest research was in the field of the calculus of vari- ations. This research was devoted to the development of direct methods for the solution of extreme problems which do not re- quire regularity or quasi -regularity of the corresponding oper- ations. At an international congress devoted to problems of the calculus of variations, his paper entitled "New Methods in the Calculus of Variations," was awarded the A. Mertani Prize of 57 BOGOLYUBOV the Bologna Academy of Sciences. A number of the investi- gations by Bogolyubov have dealt with the theory of quasi - periodic functions. He showed that the basic theorems of quasi- periodic functions (for instance, the theorem of the uniform approximation of a continuous quasi -periodic function by trigo- nometric sums) result from one general theorem in the field of an arbitrary limited function. According to this theorem, certain linear combinations from an arbitrary limited function are capable of being approximated by trigonometric sums. The proof of the approximation theorem for the quasi -periodic functions of Bohr, presented by Bogolyubov, does not rely upon the Parseval equality; in general, it relies upon virtually none of the properties of functions quasi-periodic in the sense of Bohr. In the proof of this theorem, the underlying principle is an original purely mathematical conception of the properties of quasi -periods. In this Bogolyubov has presented a virtually new synthesis of Bohr's theory of quasi -periodic functions. Bogolyubov has carried out a series of investigations dealing with the theory of differential equations with limiting con- ditions, directly linked to the application of the differentiation method to the calculus of variations. The basis of these in- vestigations is the estimation of error in the approximate de- termination of proper values and characteristic functions of the boundary. The approximation method developed here by Bogolyubov is applicable not only to the solution of boundary problems, but also to the solution of partial differential equations. Starting in 1932, he began work with N. M. Krilov on the development of a completely new branch of mathematical physics—the theory of nonlinear oscillations which they called nonlinear mechanics. It should be noted that, in the twenties, the rapid development of radio and electrical engineering re- quired a study of nonlinear oscillations. The use, for this pur- pose, of methods developed by A. Poincare and A. M. Lyapunov was completely inadequate. It was necessary to develop new, more flexible methods of investigation of all the complex phe- nomena originating in nonlinear oscillatory systems. The re- search of Bogolyubov developed in two principal directions: that of the development of methods for the asymptotic integration of nonlinear equations describing oscillatory processes, and that of the mathematical substantiation of these methods, and this was equivalent to the development of a general theory of dy- namic systems. In the first of these directions, having to do with the study of differential equations with a "small" or "large" parameter. BOGOLYUBOV 58 Bogolyubov was successful in extending the methods of the turbulence theory to general nonconservative systems and in developing new asymptotic methods in the theory of nonlinear oscillations. These asymptotic methods, grounded in mathe- matics, not only permitted a solution in the first approximation" (as, for instance, does the Van der Pohl method) but also in higher degrees of approximation and could be applied to the study of both periodic and quasi-periodic oscillatory processes. These methods were simple for practical use embodying a high- ly effective principle of equivalent linearization, the symbolic method, etc. A number of investigations by Bogolyubov in nonlinear me- chanics deal with the rigorous foundation of asymptotic methods, the estimation of error over a finite interval, the determination of correspondence of some properties of precise and approxi- mate solutions over an infinite interval, and the proof of some existence and stability theorems of quasi -periodic solutions. Interesting and elegant theorems were proven in the investi- gation of stationary oscillatory processes. Making use of the Poincare-Lyapunov theory, as well as of the Poincare-Danzhua theory of trajectories on a tore, he was successful in investi- gating the nature of a precise stationary solution in the vicinity of an approximate solution. In the theoretical field of nonlinear mechanics he also investigated the abstract theory of dynamic systems. He made a full investigation of the structure of the invariant dimensions of a compact dynamic system. A study was made of the existence and the basic properties of ergodic numbers emerging in the phase space of a dynamic system, corresponding physically to a stationary oscillation science. In his first works in theoretical physics, which were related to asymptotic methods, Bogolyubov examined problems dealing with the influence of a random force on a harmonic oscillator, and the establishment of statistical balance in a system con- nected to a thermostat. A number of his investigations deal with questions in sta- tistical mechanics of classical systems. Here, he has de- veloped a method of distribution functions, the essence of which lies in the development of analytical calculation methods which give probability distribution function of the particle complexes in the examined system. On the basis of Gibbs' distribution, he arrived at a method for constructing a system of equations for these functions, and indicated methods of their solution for various cases. Extending the technique of distribution functions to the case of unbalanced processes, Bogolyubov approaches 59 BOGOLYUBOV from a single point of view the theory of and the calculation of kinetic equations for systems of interacting particles, and pro- vided a general procedure for synthesizing them based on the fundamental theorems of statistical mechanics. He obtained results of no lesser importance in quantum sta- tistics. Generalizing for the case of quantum systems the method of kinetic distribution functions, he provided a general method of constructing kinetic equations for quantum systems. Interesting results were also obtained by him in questions con- nected with the behavior of electrons in metal. Here he de- veloped a method of approximate second quantization based on the fact that, under certain assumptions, it is possible to repre- sent the energy spectrum of a Fermi system in the form of an aggregate of elementary excitations that are subject to Boze statistics. Highly important accomplishments of Bogolyubov are set forth in investigations dealing with superfluidity and super- conductivity. It is well known that quantum systems consisting of a large number of identical particles manifest, at low tem- peratures, the highly unique phenomenon of degeneration. This phenomenon had been studied only for ideal gases. The first results in the theory of the degeneration of non-ideal gases were obtained by him as early as 1947, it being shown that a weakly non-ideal Boze gas can occur in a degenerate state and will then possess the property of superfluidity. In this manner, the first step was made toward the development of the micro- scope theory of the superfluidity of Helium II. Development of the ideas and methods which he expressed in his works of 1947 and 1948 made it possible for him to evolve in 1958 a systematic microscopic theory of superconductivity. An important part in understanding the essence of superconduc- tivity was played by Froelich's idea of the decisive role of the interaction of electrons with lattice oscillations, and the pre- diction on that basis of the isotopic .effect. It was, however, impossible to solve the problem on the Hamiltonian basis pro- posed by Froelich on account of the many difficulties of a pure- ly mathematical nature. Bogolyubov was successful in solving this problem and, as a result, not only developed a systematic theory of superfluidity, but also established the fundamental fact that superconductivity may be regarded as the superfluidity of an electron gas, or more generally, as the superfluidity of Fermi systems. Recently these results have found application in nuclear theory. BOGOLYUBOV 60 In the field of quantum field theory Bogolyubov made an at- tempt at a completely new synthesis rejecting the Hamiltonian formalism and replacing it by physical conditions, notably that of causality. A systematic exposition of quantum field theory is given by him in the monograph, "Introduction to the Theory of Quantum Fields." Bogolyubov also gave a rigorous proof of the so-called dispersional relations, introducing a new method in quantum field theory. He uncovered the underlying premises of quantum field theory necessary for the derivation of dis- persion relationships, and provided rigorous proof for the validity of these relations. He proved a series of theorems ly- ing on the borderline of the theory of multiple complex variables and the theory of generalized functions. Bogolyubov has attended the Pugwash Conferences. As of 1961, Bogolyubov was a Member of the Presidium of the Siberian Branch U.S.S.R. Academy of Sciences. Bibliography: Problems of Dynamic Theory in Statistical Physics. Moscow-Leningrad: 1946.

M. Brekhovskikh was born May 6, 1917. He graduated in 1939 from the University of Perm. In 1953 he was appointed professor at Moscow University, and in 1954 he was made Di- rector of the Acoustical Institute, U.S.S.R. Academy of Sciences. Since 1953 he has been a Corresponding Member of the U.S.S.R. Academy of Sciences and in 1951 he was the recipient of a Stalin Prize. Brekhovskikh' s early investigations are on scattering of x-rays in crystals and liquids. From 1942 his main scientific interest has been in acoustics and wave propagation. He investi- gated the propagation of sound and electromagnetic waves in heterogeneous media and developed the theory of wave fields and point sources in layer -heterogeneous media. In particular, he presented a theory on the so-called side and head waves, which play an important role in seismographic surveys. A number of Brekhovskikh' s investigations are in the scattering of sound electromagnetic waves on uneven surfaces. Together with others, he discovered (1946) the super -distance propagation of sound in the sea. Bibliography: Reflection of spheric waves from a plane boundary of a section of two media. Zhur. Tekh.

He invented an anhydridic cement. As a result of his study of the chemical processes during hydration and solidification of blast furnace slag, Budnikov discovered new types of hydraulic cement— sul- fated non-clinker and low-clinker slag cements, high quality, quick hardening and expanding cement —which were widely util- ized. Work was carried out by Budnikov in the field of hydro - thermal processing of building materials, and refractory ma- terial for the coke, chemical and metallurgical industries. A series of his works is devoted to the thermo-chemistry of bind- ing agents, the chemical and thermal stability of refractory ma- terial, and corrosion of cements and concrete. He studied re- actions in solid phases in silicate systems and developed new methods of investigating silicates. Bibliography: Gypsum, Its Study and Utilization, 3rd ed.

In 1915 he gradu- ated from Leningrad University and taught there becoming a professor in 1932. He was a student of L. A. Chugaev (1873- 1922, professor of Inorganic Chemistry at Leningrad University and founder and director of the Institute for the Study of Plati- num of the U.S.S.R. Academy of Sciences). Beginning in 1918, he also worked at the Institute on the Study of Platinum of the U.S.S.R. Academy of Sciences. From 1934 Chernyaev worked 75 CHERNYAEV at the Institute of General and Inorganic Chemistry of the U.S.S.R. Academy of Sciences and in 1941 became its Director. In addition, he was professor of Moscow Petroleum Institute from 1935 to 1941. And in 1945 he was made professor at Moscow University. Chernyaev was elected Corresponding Member of the U.S.S.R. Academy of Sciences in 1933 and in 1943 Academician. In 1946 and 1952 he won Stalin Prizes. Chernyaev has investigated the chemistry of complex com- pounds. In 1915 Chernyaev completed an investigation of hydroxylamine compounds of divalent platinum. In 1926 Chern- yaev published his work on the study of nitro compounds of divalent platinum. Using these compounds he discovered trans- influence. It is constituted by the fact that the dependence of the reaction ability of any substitute in the internal sphere of a complex compound depends upon the nature of the substitute which is in contraposition to it. This phenomenon, associated with his name, was found to be applicable to a series of com- pounds of tetravalent platinum, palladium, rhodium, iridium and cobalt. Using transinfluence, Chernyaev and his students synthe- sized many complex compounds. Chernyaev discovered the change in the sign of the rotation of a plane of polarization by optically active amino compounds of tetravalent platinum during their transformation into amido- (or imido-) compounds. He studied the oxidation reaction of complex compounds of platinurti, reduction of iridium, proved that the binding of the nitro group with platinum takes place through nitrogen, and studied the heat of reactions of complex compounds. A considerable number of Chernyaev' s investigations are devoted to refining of platinum metals. As a result he obtained platinum, palladium, gold and rhodium in a spectrally pure state. As of 1961, Chernyaev was Chairman of the Commission for Considering Works Submitted in Competition for the N. S. Kurnakov Award. As of September 1962, Chernyaev, at his own request, was relieved of the directorship of the U.S.S.R. Academy of Sciences Institute of General and Inorganic Chemistry and resumed his former position as Chief of the Section on Simple and Complex Inorganic Compounds of this Institute.

He is one of the founders of colloidal chemistry in Russia. He graduated in 1903 from ICiev Polytechnical Institute where, until 1913, he conducted his investigations. In 1913 he organized in Voronezh a Laboratory of Colloidal Chemistry which was reorganized in 1932 into the All-Union Scientific Research Institute of Colloidal Chemistry. Until 1942 he was Director of this Institute. In 1946 he became Director of the Institute of General and Inor- ganic Chemistry, Ukrainian S.S.R. Academy of Sciences. Du- manskii has been a Corresponding Member of the U.S.S.R. Academy of Sciences since 1933, and since 1945 an Academician of the Ukrainian S.S.R. Academy of Sciences. He is the founder and editor, since 1935, of the Colloidal Journal. While studying dispersed, chiefly colloidal systems, Du- manskii introduced physical methods for research in colloidal chemistry. He observed an increase in the concentration of salts with the introduction of gelatin to their solution, which was helpful subsequently in explaining the role of water, bound to colloidal particles. Instead of using animal membranes for in- vestigating the properties of a medium surrounding colloidal particles (a dispersed medium), Dumanskii introduced, in 1908, the use of collodion membranes, later widely utilized in chemis- try and biology. He introduced the use of a powerful centrifuge for measuring the size of colloidal particles. Dumanskii' s widespread investigations in the utilization of physico-chemical 93 DZHELEPOV diagrams (allowing to clearly outline the conditions of sedimen- tation and formation of colloidal solutions) in colloidal systems had considerable practical significance. The works of Du- manskii, and his students on the solvation of colloidal systems lead to considerable changes in the theory under question and in the technology of a number of fields in practical colloidal chemistry (agronomy, sugar, fermentation, starch-molasses, bread baking and other industries).

Dzhelepov was born December 12, 1910. He graduated from Leningrad University in 1931, and from then until 1943, he worked at the Physico-Technical Institute of the U. S.S.R. Academy of Sciences. In 1935-1941 and again in 1944, he taught at Leningrad University. He worked in 1939-1941 and also in 1946 at the All Union Scientific Research Institute of Metrology. DZHELEPOV 94 Beginning in 1945, Dzhelepov has worked at the Radium Institute of the U.S.S.R. Academy of Sciences. He was elected, in 1953, a Corresponding Member of the U.S.S.R. Academy of Sciences. Dzhelepov' s field is nuclear physics. In 1932-41 he studied the energy spectra of electrons emitted by artificially created radioactive elements. In 1938 he designed a gamma spectrome- ter, based on pair formation. In 1948, together with Orbeli, he developed a gamma spectrometer, based on the measurement of recoil electron energy knocked out by gamma rays in the direction of its initial movement. In 1954 this method was im- proved and a new device was built. Dzhelepov and associates studied beta and gamma spectra and spectra of conversion elec- trons of more than thirty radioactive isotopes. Together with N. A. Vlasov, he studied the angular distribution of quanta formed during positron annihilation, which permitted the evalu- ation of the velocities of positrons at which they are annihilated in solid bodies. Dzhelepov analysed data on beta disintegration, on mirror nuclei, and on isotopic spin. Bibliography: and L. N. Syryanova. Influence of the Electric Field of an Atom on Beta Disintegration.

Engel'gardt's main investigations are devoted to the study of the regularities in the transformation of organic phosphorous compounds in processes of cellular metabolism, their role in the exchange of energy and in the physiological functioning of the cell, the study of the interrelation of energy processes and the mechanical reaction of muscle protein. His investigations aided the establishment of definite ties between chemical phe- nomena in the muscle fiber and its function. Engel'gardt dis- covered the process of aerobic resynthesis of adenosine tri- phosphoric acid. He established that the contracting protein of the muscle, myosin, has the properties of an adenylpyrophos- phatase enzyme and by splitting the adenosine triphosphoric acid, obtains energy for its functioning. Engel'gardt also in- vestigated vitamins, and studied the technology for vitamin production and their quantitative determination. As of 1961, Engel'gardt was Chairman of the U.S.S.R.

In 1922 he gradu- ated from Petrograd University and remained there for further study, becoming a professor in 1932. He worked at the follow- ing institutions: the State Institute of Optics (1919-23, 1928-41), the Leningrad Institute of Physics and Technology (1924-36), and the Institute of Physics of the U.S.S.R. Academy of Sciences (1934-41, 1944-53). In 1954 he was appointed to the staff of the Institute of Physical Problems of the U.S.S.R. Academy of Sciences. Fock became a Corresponding Member of the U.S.S.R. Academy of Sciences in 1932 and in 1939, an Acade- mician. He was awarded, in 1946, a Stalin Prize, and a Lenin Prize in 1960. As of 1960, he was still teaching at Leningrad University. In April 1959, he visited the United States to attend Harvard University as a Leningrad exchange scientist. In 1958 he was elected a Foreign Member of the Norwegian Royal So- ciety in Trondheim. The basic research of Fock deals with quantum mechanics, quantum electro -dynamics, the theory of electromagnetic dif- fraction and radio-wave propagation, the general theory of rela- tivity, mathematics, and mathematical physics. His early work is devoted to mechanics of elastic bodies and to theoretical optics. In 1924 he established basic concepts of the theory of the illumination vector in the optical field. Fock's most im- portant contribution to mechanics is the solution of two- dimensional static problems in the theory of elasticity. This he carried out using the integral equation of Fredholm. In 1926 109 FOCK Fock worked out a theoretical approach to the wave equation of quantum mechanics for a charged particle in a magnetic field, proving for the first time its "gauge -invariant" properties. As a consequence of the above investigation Fock arrived at the scalar relativistic wave equation for a particle with no spin in an electromagnetic field, independently of similar work by the Swedish physicist O. Klein. This equation is often referred to as the Klein- Fock equation. In 1930 Fock derived from a variational principle the equations of the self- consistent field in the quantum theory of the atom, taking due account of the symmetry properties of the wave function; he developed an ap- proximation method for determining the energy states and transition probabilities of polyelectronic atoms. The method is also used in the theory of molecular structure and in the theory of solids. Fock's most important contributions to the field theory are investigations in second quantization and quantum electrodynamics. In 1932 and 1934 Fock developed a method permitting a quantum description of systems with a variable number of Bose particles (e.g. photons); he uses a functional, dependent on an infinite set of wave functions in spaces of in- creasing number of dimensions (Fock space) and on an auxiliary function (the field variable). In 1939 Fock solved Einstein's gravitational equations for an "insular" distribution of masses (like the Solar system), proving that gravitation equations also ■ include equations of motion. In his monograph "The theory of space, time and gravitation" (1955) Fock interprets Einstein's gravitation theory from his own point of view, drawing a sharp distinction between the physical principle of relativity and the mere co-variance of differential equations; he also insists on the importance of the idea of unity between metric and gravi- tation, as opposed to the idea of relativity of motion, which is of limited application only (according to Fock, a general principle of relativity does not exist). Fock's other scientific achieve- ments are in the integral equation_s, the various applications of conformal representation, the theory of the puncture of di- electrics, the methods based on electricity to detect mineral resources, the theory of core sampling by electrical means, and the theory of diffraction of radio-waves. He also published a number of papers on the interpretation of quantum mechanics. Bibliography: The problem of many electrons in quantum mechanics and atomic structure.

Karpov Physico- Chemical Institute in Moscow. Frumkin spent 1928-29 at the University of Wis- consin, U.S.A., as a lecturer in colloidal chemistry. In 1930, he was elected to the chair of electrochemistry at the Moscow University. He was appointed, in 1939, to the staff of the 115 FRUMKIN Institute of Physical Chemistry of the U.S.S.R. Academy of Sciences, and from 1939 to 1949 was the Director. Since 1932 he has been an Academician of the U.S.S.R. Academy of Sci- ences. He received a Lenin Prize in 1931, and in 1941 a Stalin Prize. Frumkin's research is primarily in surface phenomena and in the theory of electrochemical processes. He applied the Gibbs equation to adsorption and derived the equation for ab- sorbed molecules on a surface. He developed the concept of the structure of the electrical double layer at the solid-liquid inter- face. In his experiments, he established the quantitative theory of the influence of the electric field on molecular adsorption. By means of measurements of potential jumps on the liquid-gas interface, he studied the nature of chemical bonds in molecules. In 1929, Frumkin developed the theory of kinetics in electro- chemical reactions based on the composition of the solution and the structure of the double layer. He also recognized the im- portance of the zero potentials at the metallic electrodes. With V. G. Levich, Frumkin developed a theory of diffusion process- es which take place in solutions while under the influence of an electrical field. He explained the mechanism of a number of electrochemical reactions, such as the reduction of oxygen and other anions. He has many pupils among the Soviet electro- chemists. His scientific work found application in the gener- ation of electrical energy by chemical sources, the wetting of metals by electrolytes, flotation, polarography, heterogeneous catalysis, and colloidal chemistry. In 1958 Frumkin was appointed Director of the Institute of Electro -Chemistry of the U.S.S.R. Academy of Sciences.

He was a postgraduate student at Moscow Uni- versity in 1935, where in 1940, he was granted the degree of Doctor of Physical-Mathematical Sciences. He was made a professor in 1943. In 1932 he began his employment with Mos- cow University, and since 1939 has been working at the U.S.S.R. Academy of Sciences Institute of Mathematics. He is also working at the Institute of Biophysics. In 1951 he was awarded a Stalin Prize for his work in the theory of representation of groups. He was elected to the U.S.S.R. Academy of Sciences as a Corresponding Member in 1953. In his thesis for the candidate's degree, Gel'fand developed the theory of integration of functions. His thesis for the Doctor's degree was devoted to the theory of normalized rings. This theory served as a basis for functional analysis in the most varied areas of mathematics: theory of trigonometric series, group theory, theory of differential equations. Since 117 GELFOND 1943, he has been working on the theory of unitary infinitely measureable representations of continuous groups. At the same time, he has been occupied with the theory of generalized func- tions and their application in differential equations, and also in quantum mechanics. Bibliography: Normierte ringe.

A. Grigorev was born November 1, 1883. In 1907 he graduated from Petrograd University. He organized in 1918 the Geographic Institute in Petrograd where he was a professor and dean until 1925. From 1925 to 1936 he was a professor at Leningrad University. In 1918 Grigorev organized in the Acade- my of Sciences an industrial geography department of the com- mission which studied the natural productive forces of Russia. This department became in 1931 the Geographic Institute of the U.S.S.R. Academy of Sciences, and until 1951, Grigorev was the Director. He has been an Academician of the U.S.S.R. Academy of Sciences since 1939. In 1946 he became a member of the Communist Party of Soviet Russia. He was awarded a Stalin Prize in 1947. He is a member of a number of scientific socie- ties including the Geographic Society of the U.S.S.R. Grigorev is on the main editorial board of the Bol'shaya Sovetskaya Entsykl. (Great Soviet Encyclopedia). He has been active in the Society for the Dissemination of Political and Scientific Knowledge. Also he is interested in the history of Russian geography. In 1904, and again in 1921, Grigorev completed an expedition to the Bolshezemelskaya tundra. At various times, he investi- gated little -known regions of the South Urals (1923), Yakutsk, ASSR (1925-26), the Kolskii Peninsula (1928-29 and 1931), and Kazakhstan, carefully studying the elements of the geographical environment. His results have been useful to soil scientists, GRINBERG 132 paleographers, geo mo rpho legists, and geobotanists. Grigorev has published more than 300 articles. His monograph. The Subartic, sums up the material on the tundra belt, and was the first geography treatise to be awarded a Stalin Prize. In his articles from 1928-1930, he introduced a new direction in ge- ography, subsequently named "dynamic geography," in which great stress is paid to natural processes. He has attempted to convert geography from a descriptive science to one which es- tablishes general laws of physico-geographical processes, based on studies of the paleography of the Quaternary Period, on discoveries of fresh-water diatomites, and on the evolution of phy si CO -geographic processes on the earth's surface since the Devonian Period.

Academy of Sciences Institute of Microbiology, where he became Director in 1949. He was elected to the U.S.S.R. Academy of Sciences in 1946 as a Corresponding Mem- ber, and in June 1962, an Academician. Imshenetskii' s researches are in the structure, biology, indi- vidual growth, variation and physiology of micro-organismso In studying the construction of bacteria, he proved that the ma- jority of them retain a significant amount of vital substance but lack an individual morphological nucleus and that the latter is found only in complex bacteria. He explored changes in the structure of bacteria in the process of ontogeneses under the influence of various external factors which enabled him to dis- cover the metaphysical essence, the so-called theory of cyclo- genics. His other work is the study of the biology of bacteria which attack cellulose. His work includes a study on the influ- ence of increased temperatures on the course of microbiologi- cal processes (a comparable study of the nature of mesophilic and thermophilic bacteria was made). He has explored groups of cellulose, amylolytic, proteolytic and thermophilic bacteria, which are of practical value. He showed ways of replacing the mesophilic bacteria with the thermophylic which hastens the course of microbiological processes (for example— fermen- tation). A series of his research deals with the biology and physiology of nitrifying bacteria; the variability and selectivity of yeast, mold fungus and bacteria. 139 ISHLINSKII In April 1960, Imshenetskii visited the United States on an exchange program at the Rockefeller Institute for Medical Re- search in New York City.

He graduated from the Tomsk Technological Institute in 1914, after which he worked at a scientific research institute in Baku until 1937 as the Director of the Office of Turbodrilling and Crack- ing. He was awarded the title Honored Scientist of the R.S.F.S.R. in 1947, and was elected to the U.S.S.R. Academy of Sciences as a Corresponding Member in 1939. In 1912 he proposed turbodrilling of oil wells. The first turbodrills had a single-stage turbine and a reducer for di- minishing the speed of the working shaft connected to a drill. Later, a group of engineers under the leadership of P. P. Shumilov developed a multi-stage reducerless turbodrill, which was widely utilized. In 1924-31 Kapelyushnikov, together with V. G. Shukhov, designed and built the first Soviet cracking plant. In 1933, together with S. D. Zalkin, Kapelyushnikov developed pneumatic control of a drilling rig. In 1952, he established the fact that dissolving oil in gas under considerable pressure makes it possible to explain the conditions in the migration of oil and formation of deposits. 145 KAPITSA Bibliography: The mechanization and automation of drilling.

Kapitsa was born July 8, 1894. In 1918 he graduated from the Polytechnic Institute in Petrograd (Leningrad) and began scientific work under A. F. loffe (1880-1959, solid state physicist). He was sent in 1921 on a scientific trip to England where he worked until 1930 under E. Rutherford in the Caven- dish Laboratory at Cambridge University. From 1930 to 1934 he was Director of the Monde Laboratory at Cambridge Uni- versity. In 1935 Kapitsa was persuaded to remain in the Soviet Union. From 1935 to 1946 and again in 1955 he was Director of the Institute of Physics Problems of the U.S.S.R. Academy of Sciences. He was elected a Corresponding Member of the U.S.S.R. Academy of Sciences in 1929 and an Academician in 1939. In 1941 and in 1943 he received Stalin Prizes. He was made a Hero of Socialist Labor in 1945. Kapitsa is editor of the Soviet Journal of Experimental and Theoretical Physics. He was a member of and honored by many foreign organizations including: London Royal Society (1929), Danish Academy of Sciences (1946), National Academy of Sciences of the U. S. A. (1946), English Institute of Metals (1943), Franklin Institute in the U. S. A. (1944), Paris University, University of Oslo, Uni- versity of Algiers. The first investigations of Kapitsa are devoted to the study of the inertia of electrons and properties of radiation. In 1920, in the article, "The Possibility of Determining the Magnetic Moment of the Atom," Kapitsa, together with N. N. Semenov, proposed an experiment on the determination of magnetic moments of atoms in atomic beams. Kapitsa constructed an KAPITSA 146 installation for creating very powerful magnetic fields. He ob- served the splitting of spectral lines in fields up to 320 kilo- gauss, discovered linear increase of electrical resistance of metals with the field, and studied magnetostriction of diamag- netic bodies in these fields. Kapitsa developed a large capacity hydrogen liquifier of helium by using the adiabatic principle. He proposed a new method of liquifying air in a low pressure cycle and for using a turbine engine driven by compressed gas. Using a turbine engine driven by compressed gas to liquify air, Ka- pitsa built an installation (1939) for obtaining large quantities of liquid oxygen by way of fractionation. He is the author of the treatise on ''Turbine Engine Driven by Compressed Gas for Ob- taining Low Temperatures and Its Application in Liquification of Air" (1939; Stalin Prize 1941). He conducted investigations on the properties of liquid helium H and discovered (1938) the phenomenon of super fluidity. The results of these investi- gations are in "Heat Transfer and Super Fluidity of Helium 11" (1941) and "Investigating the Mechanism of Heat Transfer in Helium II" (1941; Stalin Prize 1943). In connection with the study on the operation of a fractionating column, Kapitsa con- ducted investigations on the wave heat processes in moving thin layers of liquid. Later development of this work led to the es- tablishment of a quantitative theory on interaction of marine waves with the wind. Kapitsa developed a hydro -dynamic theory of lubricating bearings. In 1951 he published studies on the movement of a pendulum with a vibrating suspension device and proposed a hypothesis on the nature of ball lightning (1955). In 1960 Kapitsa was awarded the Lomonosov Gold Medal for his work in low temperature physics. As of 1961, Kapitsa was a Member of the Presidium of the USSR Academy of Sciences. In June 1958, he visited the United States to attend the Gordon Research Conference on Polymer Research at New London, New Hampshire. He has also attended the Pugwash Conferences.

In 1918 he gradu- ated from Moscow University where he was a pupil of N. D. Zelinskii, the leader of Russian organic chemistry in the first part of this century. He was made professor in 1935 at Moscow University. And in 1936 he was in charge of and organized the catalytic synthesis laboratory at the Institute of Organic Chem- istry at the U.S.S.R. Academy of Sciences. In 1954 he became Director of the Zelinskii Institute of Organic Chemistry. Since 1946 he has been an Academician. He was awarded, in 1949, a Stalin Prize. Kazanskii has specialized in the conversion of hydrocarbons. In particular, he has investigated hydrogen cleavage of five- membered hydrocarbons in the presence of platinum catalyst. This reaction points the way for conversion of these hydro- carbons into branched paraffins. In 1936 Kazanskii studied the aromatization of paraffins in the presence of platinized carbon at 300° to 310°. Later he determined that an intermediate of this reaction is cyclohexane. In 1954 he showed that in the presence of platinum, paraffins can also convert to hydro- carbons of the cyclopentane series. This cyclization goes to the greatest extent for branched paraffins (isooctane). He also studied aromatization in the presence of different oxides as catalysts. He investigated selective hydrogenation of compounds with several double bonds in the presence of platinum, palladi- um, and nickel. Recently he has investigated the conjugation of 151 KAZARNOVSKII trimembered cyclic hydrocarbons with a double bond in the side chain (vinylcyclopropane) or in the aromatic nucleus (phenyl- cyclopropane). With G. S. Landsberg, he developed a method for detailed study of petroleum, using Raman spectra. In 1961 Kazanskii was awarded the Order of Lenin and two orders of the Red Banner of Labor. He was also a member of the steering Committee of International Union on Pure and Applied Chemistry. Bibliography: with A. F. Plate.

He is the son of Vsevolod Mikhaylovich Keldysh (1878, a specialist on ferro-concrete construction and a pro- fessor). In 1931 he graduated from Moscow University. Join- ing the N. Ye. Zhukovskii Central Aero-Hydrodynamics Institute (TsAGI), Keldysh worked during 1934-35 in its Department of Flutter Engineering and in 1943 and in 1945 was a department chief in the Institute. In 1939 he became associated with the V. A. Steklov Mathematics Institute of the U.S.S.R. Academy of Sciences and in 1954 was made Director of that institute's De- partment of Applied Mathematics. He has been a member of the Communist Party of the Soviet Union since 1949. In 1943 he was elected a Corresponding Member of the U.S.S.R. Academy of Sciences and in 1946 an Academician. He was named academician- secretary of the Academy's Department of Physico- Mathematical Sciences in 1953, has served on the Academy's Presidium since 1953, and in 1960 was elected one of the vice presidents. In 1961 Keldysh replaced A. N. Nesmeyanov as President of the U.S.S.R. Acade- my of Sciences. In 1957 Keldysh was named to membership on the Presidium of the newly formed U.S.S.R. National Committee on Theoreti- cal and Applied Mechanics, U.S.S.R. Academy of Sciences. The following year he was cited as a member of the organization committee of the All- Union Conference on Theoretical and Ap- plied Mechanics, and when that conference convened in Moscow 153 KELDYSH during January 27- February 3, 1960, he served as chairman of the Section on General and Applied Mechanics. Since 1956 he has been a member of the editorial boards of the journals Matematicheskii Sbornik, Novaya Seriya, and Prikladnaya Matematika i Mekhanika. Among the honors and awards that have been conferred upon Keldysh are the Order of Labor Red Banner (in 1943, 1945 and 1953) and the Order of Lenin (in 1945, 1954 and 1960). He re- ceived a Stalin Prize in 1941 for scientific works in predicting the breakdown of airplanes. In 1960 he was made a member of the Presidium of the Committee for Awarding Lenin Prizes in the Field of Science and Engineering of the Council of Ministers U.S.S.R. Keldysh' s interests in mechanics and mathematics are theo- ry of oscillations, aerodynamics, theory of waves on the sur- face of a heavy liquid, impact against water, investigation of an approximate integration of differential equations, potential theory, conformal representation mapping, theory of eigen- functions and eigenvalues of parameters for non self -conjugate differential equations. In hydromechanics, he worked on the theory of non-stabilized motion of a wing. He proved, for gas, the theorem of Zhukovskii. He presented a theory on the solva- bility of the Dirichlet problem in its dependence on boundary conditions. He solved the basic problems of the stability of solutions of the Dirichlet problem. Keldysh developed a theory of approximation of functions of a complex variable by a series of polynomials. Of considerable importance is the work of Keldysh on the theory, calculation and working out of methods for avoiding various types of vibration in an airplane. Since 1953 his papers have discussed such topics as thermal exci- tation of sounds, speed of approximation of functions by poly- nomials on arbitrary continua, point character of the spectrum of a certain class of matrices in an analytical space and series of rational fractions.

B. Khariton was born February 27, 1904. In 1925 he graduated from Leningrad Polytechnic Institute. While still a student, in 1921, he began scientific work at the Laboratory of N. N. Semenov of the Leningrad Physico -Technical Institute. In 1927-28 Khariton was sent to England where he studied the scintillation of alpha-particles under E. Rutherford. In 1931 he began working at the Institute of Chemical Physics of the U.S.S.R. Academy of Sciences. He was elected a Correspond- ing Member of the U.S.S.R. Academy of Sciences in 1943 and an Academician in 1953. He was also a Deputy to the U.S.S.R. Supreme Soviet, and was elected again in March 1962. The first investigation of Khariton was the study of conden- sation of metallic vapor molecular beams in a vacuum on cooled surfaces. The result was the basis for the theory on conden- sation, later developed by Khariton and other Soviet scientists. In 1925 Khariton, while studying the phenomena of chemi- luminescence of vapors of phosphorus at low oxygen pressures, discovered the phenomenon of the lower limit of cold ignition of phosphorous vapors. He showed that below a certain pres- sure of oxygen, the reaction of oxidation does not take place, and above a certain pressure, moves with noticeable speed. Together with Ya. B. Zel'dovich, Khariton made calculations for a chain reaction of uranium fission. Khariton, and associ- ates, worked on the theory of excitation and spreading of ex- plosion detonations; in particular he established the principle KHARKEVICH 156 which links the explosive ability of substances with the speed of the chemical reaction in the explosive wave front.

He produced a series of new transformations of aliphatic oxides, which led to the synthesis of gamma- acetopropyl alcohol; this synthesis is used in production of vitamin Bi and in anti-malaria substance. Also he studied methods of introducing fluorine into organic compounds, such as the reaction of aliphatic oxides with hydrogen fluoride. At present he is concerned with reactions of fluoroolefins. Many of his inventions, such as photosensitizers and caprone, are used in Soviet industry. Bibliography: and O. V. Kild'sheva. Methods of introducing fluorine in organic compounds.

N. Kolmogorov was born April 25, 1903. In 1925 he graduated from Moscow University where he was a student of N. N. Luzin (1883-1950), Professor at the University. Kolmo- gorov became a professor there in 1931. In 1939 he was elect- ed an Academician of the U-S.S.R. Academy of Sciences. He was awarded in 1941 a Stalin Prize. Kolmogorov' s scientific works began in the field of the theory of a real variable, where he worked on the convergence of trigonometric series, the theory of measure, generalization of the concept of the integral and general theories of operation on sets. Returning in 1956 to the theory of functions, Kolmogorov obtained important results on the representability of functions of a number of variables by superposition of functions with a smaller number of variables. Kolmogorov made contributions to constructive logic; in topology he created the theory of the so-called "upper" or V-homologies. Kolmogorov also worked • on the theory of the approximation of functions and functional analysis. His more outstanding works are concerned with the theory of probability, where he, together with A. Ya. Khinchin, began from 1925 to apply the methods of the theory of functions of a real variable. This permitted the solution of some difficult problems and construction of a system of axiomatic foundation to the theory of probability (1933). From the beginning of the 1930' s, analytical methods which were found essential for con- structing the theory of the Markov processes with continuous time predominate in the works of Kolmogorov. Later he de- veloped the theory of stationary, accidental processes, which led to results used in automatic control, and to the establish- ment (together with a group of students) of a theory of ^^ branch- ing," accidental processes. Kolmogorov worked together with A. M. Obukhov on the statistical theory of turbulence; he also investigated the theory of fire, statistical methods of control- ling mass production, the theory of conveying information along communication channels. He is interested in the teaching of mathematics in secondary schools. Among his students are: KOLOSOV 172 A. I. Mal'tsev, S. M. Nikol'skii, I. M. Gel'fond, B. V. Gnedenko, A. M. Obukhov, M. A.

P. Kostenko was born December 16, 1889. Before gradu- ating in 1918 from the Electrical Engineering Institute of the Petersburg Polytechnic Institute, Kostenko had been banished for a period to a remote corner of the Urals by the Tsarist Government for having participated in student revolutionary demonstrations. After graduating with distinction, he remained at the Institute to prepare for teaching activities. In 1930, he was appointed to the Chair of Electrical Machines in the M. I. Kalinin Polytechnic Institute. More than 400 electrical engi- neers (specialists in constructing electrical machines) have graduated from there under his direction. Kostenko was Chief Electrician of the Kharkov Electromechanical Plant, and, in 1942-44, professor in the Central Asiatic Industrial Institute (Tashkent). He is Director of the Institute of Electromechanics of the U.S.S.R. Academy of Sciences. He has consulted and taught in Rumania, Hungary, Bulgaria, and Poland. He was a delegate to the Paris Conference on Large-Scale Electrical High-Tension Systems. In 1939 he was elected a Corresponding Member of the U.S.S.R. Academy of Sciences and in 1953 an Academician. He is an Honored Scientist of the Uzbek S.S.R. He was a Deputy of the Supreme Soviet of the U.S.S.R., fifth convocation. In 1949 and 1951, Kostenko was awarded Stalin Prizes and in 1958 a Lenin Prize. Under the Lenin Plan, GOELRO (State Plan for Electrifi- cation of Soviet Russia), Kostenko was one of the originators (and is chief) of the office for new designs at the "Electrosila" Plant, where he worked from 1929-30, and where he has been consultant since 1932. In this connection, the office designed four of the eight generators for the then new Volkhov hydro- electric power plant. Their success assured the beginning of Soviet manufacture of heavy power machinery construction. Similarly, Kostenko has participated in the development of all the basic electrical machines produced in Russia: generators for plants such as the Dneprovskaya, Ribinskaya, Uglichskaya, and the Volga Cascade. He was consulted in the manufacture of motors for the atomic ice-breaker "Lenin," and for generators of the Kuibishev and Stalingrad power stations. He is a member of the technical council of Electrosila. 181 KOSTENKO At the Institute of Electromechanics of the Academy of Sci- ences of the U.S.S.R., located in laboratories in a private resi- dence on the Palace Embankment of the Neva [Leningrad], Kostenko works on the combined operation of AC and DC trans- mission lines and the automatic regulation of superpower gener- ators. The laboratories contain models of the Stalingrad power stations and of the future Volga, Krasnoyar, Bukhtarin, and Bratskaya plants. Stalingrad will transmit AC and DC simultaneously; AC to Moscow and DC to the Don Basin. The modelling methods are used there to work out the electrifi- cation of the main Russian railroad lines under the Seven Year Plan. Kostenko is working on problems of the utilization of alternating current electric traction for this purpose. Kostenko' s basic works are concerned with the theory of electrical machines and methods for their experimental study and planning. He gave a theory of transformers, polyphase asynchronous and commutating machines; worked out an origi- nal scheme of commutative generators for alternating current. He has been concerned with electric traction using alternating current, electrodynamic modelling of energy systems in con- nection with the stability and reliability of the operation of distant electric transmission, and with the rectification of alter- nating current. He has written a monograph on the universal transformer. In all, he has written over 100 scientific works, which have become indispensable manuals for Soviet engineers, especially his Commutators, printed a quarter of a century ago. As of 1961, Kostenko was a Member of the Presidium of the U.S.S.R. Academy of Sciences. Bibliography: Alternating Current Commutator Machines, Part 1. Lenin- grad: 1933. Electric Machines (part 1-2).

From 1934 to 1938, he worked in the Biological Institute of the Byelorussian S.S.R. Academy of Sciences. In 1938, he was made chief of a laboratory of the Botannical Institute of the U. S.S.R. Academy of Sciences, and from 1949 to 1952, he was Director of this Institute. In 1952 V. F. Kuprevich was elected an Academician of the Byelorussian S.S.R. Academy and President of the Acade- my of Sciences of Byelorussian S.S.R. Since 1953 he has been a Corresponding Member of the U. S.S.R. Academy of Sciences. In 1945 V. F. Kuprevich became a member of the Communist Party of the Soviet Union. He is presently a Deputy of the U. S.S.R. Supreme Soviet. Kuprevich has studied the physiology and biochemistry of diseased plants and the classification of mushrooms. He has investigated the physiology of diseased plants. He was the first to discover the presence of extracellular enzymes in obligate parasites and proposed progressive curtailment and specializ- ation of extracellular enzymatic apparatus in parasitic mush- rooms in the process of their evolution. The basis of the pathological process is the action of extracellular enzymes of a parasite on the protoplast of the host and responsive reactions of the latter which led to necrosis, or the suppression of the activity of the parasitic enzymes. Kuprevich showed that leaves can assimilate carbon dioxide transmitted along with water from other parts of the plant. These investigations led to the discovery of the feeding process of plants by carbon dioxide from the soil. Kuprevich discovered extracellular enzymes which are secreted by the thinnest roots of higher plants. He proved the possibility of heterotrophenous feeding of higher plants in natural environments and eliminated the principal 201 KURDYUMOV difference in the method of feeding of autotrophic and hetero- trophic plants.

He had been working since 1925 at the Physico-Technical Institute of the U. S.S.R. Academy of Sciences. In 1932 he began working at the Dnepropetrovsk Physico-Technical Institute, and from 1932 to 1941 he taught at Dnepropetrovsk University. Kurdyumov was appointed Director of the Institute of Metalworking and the Physics of Metals of the Central Scientific Institute of Ferrous Metallurgy (Moscow) in 1944. In 1939 he was elected Acade- mician of the Ukrainian S.S.R. Academy of Sciences. He has been a Corresponding Member of the U. S.S.R. Academy of Sciences since 1946 and since 1953 an Academician. He was awarded, in 1949, a Stalin Prize. Kurdyumov has studied the processes arising in the harden- ing and tempering of steel and the phenomena of phase transfor- mations, hardening, and diffusion in metals and alloys. To- gether with N. Y. Gudtsov and N. Ya. Selyakov, he defined (1926) the crystalline structure of martensite. The existence of the regular orientation of the crystalline lattice of martensite KURDYUMOV 202 in relation to austenite was revealed by Kurdyumov together with A. A. Ivens and G. Zaks (1929-30). He further established that the normal mutual orientation of crystal lattices of the initial and resulting phases occurs according to a general pat- tern of phase transformations in solids. In 1932-39, Kurdyumov made studies of metastable states and phase transformations in copper alloys. The theory of these transformations permitted Kurdyumov to discover in 1948 the isothermic transformation of martensite at low temperatures and the thermoelastic equilibrium in martensite transformation. In February 1962, Kurdyumov visited the United States to attend the Aluminum Symposium and annual meeting of the American Institute of Mining, Metallurgical, and Petroleum Engineers.

In 1927 he graduated from Leningrad State University. He began working in 1937 at the Institute of Physical Problems of the U.S.S.R. Academy of Sciences. In 1943 he became a professor at Mos- cow State University. He has been an Academician since 1946. He was awarded a State Prize in 1946, Lenin Prize in 1962, and two Orders of Lenin. In November 1962 Landau was awarded the Nobel Prize in physics. He is a member of numer- ous foreign scientific organizations including: the National Academy of Sciences of the United States, the English Physical Society, the English Royal Society, the Danish Royal Academy of Sciences, the Dutch Academy of Sciences, and the French Physical Society. Landau's investigations are in solid state theory and physics of low temperatures. He has worked out a thermodynamic theo- ry of the phase transitions of a secondary kind in solids bodies, and elucidated their profound connection with the qualitative change of a body's symmetry during transition. In 1940-41 Landau developed the macroscopic theory of liquid helium superfluidity which takes place in this fluid at temperatures close to absolute zero. Landau predicted the possibility of dif- fusing sound waves with two unequal speeds (phenomenon of secondary sound) in liquid helium. In his works on supercon- ductivity, Landau presented a theory on the intermediate con- dition of superconductors. In conjunction with A. Abrikosov, I. Pomeranchuk and I. Khalatnikov, Landau found a solution to the main equations of the quantum field theory, without the use of the perturbation theory, and he proved that the concept of point interaction is groundless because it leads to the absence of any interaction. Recently, in connection with the discovery of the nonconservation of parity in weak interactions. Landau pro- posed the theory of combined inversion and the theory of a '^two component neutrino." A considerable number of his investi- gations are in nuclear physics and cosmic rays. Bibliography: Continuum Mechanics, Hydrodynamics and the Theory of Elasticity. Moscow-Leningrad: 1944. and E. M.

Leontovich began working at the Institute of Atomic Energy, U.S.S.R. Academy of Sciences in 1951. In 1939 he was elected Corresponding Member of the U.S.S.R. Academy of Sciences and in 1946 Academician. He received the Gold Medal of A. S. Popov in 1952, and in 1958 a Lenin Prize. Leontovich' s investigations are in electrodynamics, optics, statistical physics, radiophysics. Important investigations by Leontovich are on the theory of molecular dispersion of light (until 1935), in ultra-acoustics [absorption of sound in gases (1936), in liquids (1936 and 1939)J, on the theory of fluctuations and statistical physics [on the basis of thermodynamic statistics (1932), on gas-kinetic equations derived from the theory on sto- chastic processes (1935)], and in various aspects of radiophysics [thermal fluctuations of the electromagnetic field in solids (to- gether with S. M. Rytov)]. Leontovich also studied the theory of radiowave propagation and the theory of antennae. He determined the approximate ratios between the components of the electro- magnetic field on the surface of a conducting medium, thus con- ' siderably simplifying mathematical treatment of the problem of radiowave propagation along the earth's surface and allowing solution of many special problems. A theory of fine wire an- tennae was completed by Leontovich jointly with his student, M. L. Levin, and published as *0n the Theory of Excitation of Oscillations in Antennae Vibrators" (1944). Leontovich partici- pated in solving practical problems in radioengineering. For his work in radiophysics and radioengineering Leontovich was awarded the Gold Medal of A. S. Popov (1952). Recently he has been investigating powerful pulse discharges in gas in an effort to obtain high -temperature plasma (Lenin Prize 1958). Bibliography: Statistical Physics. Moscow-Leningrad: 1944.

LYSENKO 226 Office: Department of Machine Strength and Dynamics Leningrad Polytechnical Institute Leningrad, USSR Residence: Polytechnical Road 3; app. 90 Leningrad K-64, USSR LYSENKO, TRQFIM DENISOV^ICH (Biologist and Agriculturist) T. D. Lysenko was born September 17, 1898. He graduated from Uman School of Horticulture in 1921 and in 1925 from Kiev Institute of Agriculture. He worked on an experimental selection station in Gandzha (now Kirovobad), Azerbaidzhan S.S.R. then at the All- Union Genetic Institute in Odessa. From 1938 to 1956 he was President of the Lenin All-Union Academy of Agricultural Sciences, and was elected a Member of the Presidium in 1960. In 1940 Lysenko was made Director of the Genetics Institute of the U. S.S.R. Academy of Sciences. He has been an Academician of the Ukrainian S.S.R. Academy of Sci- ences since 1934 and of the U. S.S.R. Academy of Sciences since 1939. In 1935 he became an Active Member of the Lenin All- Union Academy of Agricultural Sciences. Lysenko was Deputy to the Supreme Soviet of the U. S.S.R., first through fifth convo- cations. In March 1962, he was again elected deputy from the Ukrainian SSR to the Supreme Soviet. In 1941, 1943, and 1949 he was awarded Stalin Prizes and in 1945 he was a Hero of Socialist Labor. Lysenko works are in the following fields: heredity and its variability, individual development of organisms, intra- and inter -species relationships, plant nutrition. Lysenko enunciated a theory on stagewise development of plants. He proposed a method of seed treatment (vernalization) before sowing and of cotton stamping. He developed a number of new grains (vernal- ized wheat "lyutestsens 1173," "odesskaya 13," barley ^'odes- skii 14," cotton "odesskii 1." Based on a hypothesis of the con- nection between an organism and the surrounding medium he attempted to develop methods of direct changes of organic nature in agricultural plants. He attempted to convert vernal- ized non-wintering farm crops into cold-resistant winter crops. He proposed a method of soil fertilization by organic -mineral mixtures. While working on questions of vegetative and sexual hybridization Lysenko formed a number of theories on heredity and its variability. In addition to finding rules for individual development of plants, Lysenko also studied the laws of species' formation and intra- and interspecies relationships. After studying relationships among individual organisms within a 227 LYUL'KA species, Lysenko proposed a theory that in nature there is no overpopulation within the species and the struggle for survival is absent. He also postulated that the existing biological species can directly produce other species under the influence of the surrounding medium changes. These ideas are not shared by many Soviet scientists.

Lyul'ka was born March 24, 1908. After graduating in 1931 from the Kiev Polytechnic Institute, he worked at the Kharkov Turbo -Generator Plant. In 1933-1939 he worked at the Kharkov Aviation Institute. Lyul'ka worked at the Central Boiler-Turbine Institute in Leningrad in 1939-1941, and subse- quently in other scientific research and designers' organiz- ations. In 1958 he received his Doctor of Technical Sciences degree. He is a professor. Since 1947 he has been a member of the Communist Party of the Soviet Union. In 1948 and 1951, he was awarded Stalin Prizes and in 1957 Hero of Socialist Labor. He was elected, in 1960, a Corresponding Member of the U.S.S.R. Academy of Sciences. While at the Kharkov Aviation Institute, Lyul'ka began work- ing on the problem of utilizing a gas turbine as an aviation engine. In this period he worked out a theory and method of constructing high altitude and high-performance characteristics LYUSTERNIK 228 for a turbo-compression air fed engine and the expediency of using this engine as a power plant for a high-performance jet plane. In 1937-39 Lyul'ka designed the first Soviet experi- mental turbo- compression jet aviation engine. In postwar years, powerful, contemporary turbojet engines AL-3, AL-5 were built under the leadership of Lyul'ka. He has been work- ing on a series of basic engineering problems such as the ana- lytic dependence of the degeneration of a turbojet engine on the speed of flight as in its transfer into a ramjet.

V. Nalivkin was born August 25, 1889. He graduated from the Petrograd Mining Institute in 1915, and in 1920 became a professor at this Institute. From 1917 to 1949, he worked on the Geological Committee (AU-Union Scientific Research Geo- logic Institute). He was chairman from 1946 to 1951 of the Presidium of the Turkmen branch of the U.S.S.R. Academy of Sciences. From 1946 to 1953 he was the Director of the Labo- ratory on Limnology of the U.S.S.R. Academy of Sciences. Nalivkin was elected a Corresponding Member of the U.S.S.R. Academy of Sciences in 1933 and in 1946 an Academician. Since 1951 he has been a Honorary member of the Turkmen S.S.R. Academy of Sciences. In 1937 he became the chief editor of a geological survey map of the Soviet Union. He was the NALIVKIN 254 recipient of a Stalin Prize in 1946. In 1949 Nalivkin was award- ed the Gold Medal of A. P. Parpinskii by the U.S.S.R. Academy of Sciences. He was given a Lenin Prize in 1957 for scientific leadership in compiling a geological map of the U.S.S.R. (in scale of 1/2,500,000, published 1956). Nalivkin' s major work is devoted to stratigraphy and paleo- geography of the Paleozoic Era of the Urals, of the territory close to the Urals, of Central Asia, and of the Russian plateau. Nalivkin is an authority on the Devonian deposits of the U.S.S.R. Detailed study of Devonian fauna, brachiopods, has allowed him to work out the details of the stratigraphy of mid-Devonian and upper Devonian deposits in sections of the Timan Mountain ridge and the Russian plateau. His research in the Urals made the stratigraphy and paleogeography of this territory more pre- cise, has permitted separation of middle and upper Devonian and lower Carboniferous deposits by layers and showed con- siderable spreading of Silurian and earlier deposits. Studies made by Nalivkin resulted in greater knowledge of the geology and minerals of Central Asia, and also aided in the determi- nation of stratigraphic positions of Ural bauxite deposits and oil deposits in the territories close to the Urals. Nalivkin was Chairman of the National Committee for U.S.S.R. Geologists as of 1961. Bibliography: Outline of Turkistan Geology. Tashkent- Moscow: 1926.

He gradu- ated from Moscow University in 1922 and began his work there. In 1930 he was instrumental in establishing a Laboratory of Organic Chemistry at the Institute of Fertilizers and Insecto- fungicides and was its Chief until 1934. He helped the NESMEYANOV 260 University of Moscow organize a Laboratory of Metallo- Organic Compounds in 1934. In 1935 he was made professor at the University. At the same time, beginning in 1934, he worked at the Institute of Organic Chemistry of the U.S.S.R. Academy of Sciences where in 1935 he organized a Laboratory of Metallo -Organic Compounds. He became Director of the Institute in 1939. From 1948 to 1951 he was President of Mos- cow University and was active in acquiring a new building. In 1953, Nesmeyanov helped found the Institute of Scientific Infor- mation of the U.S.S.R. Academy of Sciences. Through his initia- tive, in 1954, an Institute of Organo- Elemental Compounds of the U.S.S.R. Academy of Sciences was set up and he was made the Director. Nesmeyanov has been active in social and politi- cal work. He became a member of the Communist Party of the Soviet Union in 1944 and was Deputy to the U.S.S.R. Supreme Soviet. Also he was a member of the All-World Council for Peace and the Soviet Committee in Defense of Peace. In 1939 Nesmeyanov was made a Corresponding Member, and in 1943 an Academician of the U.S.S.R. Academy of Sciences. He was elected President of the U.S.S.R. Academy of Sciences in 1951. Nesmeyanov is the leader of the Soviet school of metallo- organic specialists. In 1943 he was a winner of a Stalin Prize. Nesmeyanov' s main scientific work is in chemistry of metallo-organic compounds: lithium, boron, nitrogen, sodium, magnesium, aluminum, silicon, phosphorus, sulfur, selenium, titanium, chromium, iron, copper, zinc, germanium, arsenic, zirconium, molybdenum, cadmium, tin, antimony, tungsten, mercury, thallium, lead, bismuth. In 1929 Nesmeyanov pro- posed a diazo method of synthesis of mercury -organic com- pounds, which he and his associates later used for synthesis of metallo-organic compounds of thallium, tin, lead, germanium, arsenic, antimony and bismuth. He also studied mutual trans- formations of metallo-organic compounds, utilizing these re- actions for synthesis of previously unknown types of metallo- organic compounds of zinc, cadmium, aluminum, thallium, tin and others from mercury -organic compounds. He proved that products of addition of salts of non-transition metals to unsatu- rated compounds are metallo-organic and not complex com- pounds, discovered new classes of these compounds, and studied their chemistry. Nesmeyanov also investigated unsaturated metallo-organic compounds. He made a detailed study of the steriochemistry of their mutual transformations. Through his study of metallic derivatives of oxo-enol systems and alpha- mercurated oxo- compounds, he showed the relation between the 1 261 NESMEYANOV structure and the reactivity of metallic derivatives of tauto- meric systems and later of the tautomeric systems themselves. Nesmeyanov, and his associates, ascertained the mechanism of electrophilic replacement in saturated carbon atoms. He ob- tained diphenylchloronium, diphenylbromium, triphenyloxonium salts and studied the mechanism of decomposition of these -onium salts and of various diazonium and iodonium compounds. Nesmayanov and associates made a thorough study of the re- actions of the new metallo -organic, "sandwich" compounds, the ferrocene, and ascertained their aromatic character. He also carried out a series of syntheses based on olefin telomeriz- ation. He and K. A. Kocheshkov edited a series of monographs "Synthetic Methods in the Field of Metallo -Organic Com- pounds." Based on his experiment, Nesmeyanov advanced a series of theoretical ideas on the future development of the theory of chemical structure. Nesmeyanov was Chairman of the Council for Coordinating Scientific Work of the Academies of Sciences of Union Re- publics. He was Chairman of the Editorial Publishing Council of the U.S.S.R. Academy of Sciences. In 1962, Nesmeyanov was awarded the M. V. Lomonosov Gold Medal. Bibliography: A new synthesis method for aromatic mercury-organic salts. Zhur. Russ. Fiz.-Khim.

G. Petrovskii was born January 18, 1901. In 1927 he graduated from Moscow University. He became a professor there in 1933, and in 1951 he was appointed Rector of the Uni- versity. In 1943, Petrovskii was elected a Corresponding Member of the U.S.S.R. Academy of Sciences and, in 1946, an Academician. He was awarded, in 1946 and in 1952, Stalin PETROVSKII 286 Prizes. He is a member of the Soviet Committee on Defense of Peace. The work of Petrovskii is concerned with the theory of partial differential equations, algebraic geometry, qualitative theory of differential equations, and theory of probability. He studied the various classes of elliptical systems (1937), studied problems with initial conditions for parabolic and hyperbolic systems of equations (1936); investigated the dependence of so- lutions on initial conditions; indicated for hyperbolic equations with constant coefficients the necessary and adequate conditions of existence of lacunae, that is, those regions in the base of the characteristic cone, the initial conditions of which do not influ- ence the significance of the solution at the cone vortex (1944). For his studies on the theory of partial differential equations Petrovskii was awarded, in 1946, a Stalin Prize. Petrovskii has also solved the first boundary -value problem for the equation of heat conductivity using the most general assumptions concerning the boundary of the domain (1935), gave the solution of the Dirichlet problem for the Laplace equation by the method of finite differences in an n-measured domain (1941), studied the behavior of integral curves for the system of ordinary differential equations in the vicinity of a singular point (1934), and obtained a series of results in the theory of probability. In the area of algebraic geometry, Petrovskii studied the distri- bution of ovals of the algebraic curve of the sixth order (1935). The method allowed solution of a more general problem which gives the distribution of ovals of an algebraic curve of any order, and establishes the topological properties of algebraic surfaces and algebraic manifolds of any number of dimensions (1949). Petrovskii, together with E. M. Landis, obtained (1955- 57) evaluations of the number of limiting cycles in the ordinary differential equations, the right part of which is a ratio of two polynomials of the nth power; in the case where n = 2, their evaluation is exact. He is the author of textbooks, Lectures on the Theory of Ordinary Differential Equations (1939), Lectures on the Theory of Integral Equations (1948), Lectures on Equations with Partial Derivatives (1950), which were pub- lished many times in the U.S.S.R. and translated to foreign languages (Stalin Prize 1952). In 1961 PetrovsKii was awarded the Order of Lenin. In March 1962, he was elected delegate from R.S. F.S.R. to the Supreme Soviet. As of 1961, Petrovskii was a Member of the Presidium of the U.S.S.R.

After graduat- ing in 1933 from the University of Rome, he taught there. In 1936-1940 he worked in scientific organizations in France, 1940-1948 in the United States, and in 1948-50 at the Harwell Laboratories in England. Since 1950 he has been working in the U.S.S.R. In 1955 he became a member of the Communist Party of the Soviet Union. He was elected in 1958 a Correspond- ing Member of the U.S.S.R. Academy of Sciences. Pontekorvo showed, in 1936-39 while studying nuclear iso- merism, that isomeric transitions have a large internal con- version ratio. He obtained a beta-stable isomer by neutron irradiation of cadmium. Exciting nuclei by X-ray radiation, he discovered the phenomena of "nuclear phosphorescence". He proposed in 1943 neutron logging. In 1948, while measuring the beta spectrum of tritium, Pontekorvo showed that the mass of neutrino does not exceed 1/500 electron mass. He was the first to observe L-capture. While studying decay of u -mesons, he ascertained that during this process there was no emission of gamma rays, but the product of the decay was the electron. Pontekorvo pointed out the analogy between the processes of the capture of the u -meson with a K- shell and the usual K- capture of the electron. After 1950 Pontekorvo investigated the production of 7r° -mesons by neutrons. He predicted in 1951 production of heavy mesons with hyperons. From 1955 he studied the interaction of 7r-mesons with nucleons. PONTRYAGIN 298 Bibliography: and others. Artificial radioactivity produced by neutron bombardment. II.

Pontryagin was born September 3, 1908 in Moscow. At the age of 14 he lost his sight in an accident. In 1929 he graduated from Moscow University and in 1935 became a pro- fessor. He was elected a Corresponding Member of the U.S.S.R. Academy of Sciences in 1939 and in 1958 an Academician. In 1941 he was awarded a Stalin Prize. Pontryagin' s main works are concerned with topology and the theory of continuous groups. In 1932 he formulated the general theory of duality, which fully solved the problem of de- termination of the Betty groups of an arbitrarily open set of Euclidian space through the Betty groups of an additional closed set. In connection with the proof of the theorem of duality, Pontryagin set up a general theory of the character of commu- tative groups. This theory, and the theorems on the structure of rather wide types of topological groups completely recon- structed so-called topological algebra. The results obtained by Pontryagin on the theory of topological groups are set forth in the monograph "Continuous Groups" (1938), (Stalin Prize 1941).

He graduated from Moscow University in 1915 and has been a professor there since 1930. In 1938 he became Laboratory Chief at the U.S.S.R. Academy of Sciences Institute of Energetics. He was PROKHOROV 302 elected to the U.S.S.R. Academy of Sciences as a Corresponding Member in 1939. In 1950 he was awarded a State Prize. Predvoditelev's principal works have been in the field of molecular physics, hydrodynamics and thermal physics dealing with investigations in combustion processes, wave distribution in liquid and gas media, and with problems of gas dynamics of reactant media and physical properties of liquid. He developed a theory of heterogenous combustions which establishes a re- lationship between the chemical and physical processes facili- tating carbon combustion.

He was awarded Stalin Prizes in 1940 and 1941, and in July 1962 the Order of the Red Banner of Labor. Pustovalov' s main works deal with petrography and geo- chemistry of sedimentary rock. In 1933 he studied the problem of the geochemical species in sedimentary rock, having par- ticular significance in understanding sedimentation processes. In particular, he demonstrated the differentiation in substances from a sedimentation zone, the periodicity in the formation of sedimentary rock and commercial minerals of sedimentary derivation. While studying conditions in the formation of oil producing rock masses of Azerbaijan, Pustovalov established a link between the mechanical, the mineralogical and the chemi- cal composition of sedimentary rock (1946). In later years he has been occupied with the study of secondary changes of ancient sediments. 307 RABINOVICH Bibliography: and others.

Rebinder was born October 2, 1898. In 1924 he gradu- ated from Moscow University. He became, in 1923, a scientific worker at the Institute of Physics and Biophysics of the U.S.S.R. Academy of Sciences. In 1929 he wks made professor at the K. Liebknecht Pedagogical Institute in Moscow. He was ap- pointed, in 1934, Chief of the Department of Dispersed Systems at the Institute of Physical Chemistry of the U.S.S.R. Academy of Sciences. In 1942 he became professor at Moscow Universi- ty. Rebinder was elected Corresponding Member in 1933 and in 1946 Academician of the U.S.S.R. Academy of Sciences. In 1942 he won a Stalin Prize. Rebinder' s investigations deal with surface adsorption layers on solid-liquid boundaries and their influence on the properties of dispersed systems. This work has had considerable REBINDER 312 significance for the development of the theory of flotation of minerals. He has also studied the processes of dispersion and formation of a new crystalline phase and applied these to thix- otropy, and to setting and hardening of cements, to the stabili- zation of foams, emulsions and suspensions, and to phase changes in emulsions. He investigated the mechanical proper- ties of rheological systems and established the effect of small additions of adsorbing substances. Rebinder has indicated deformations can be eased and the mechanical stability of solids (in particular metals) can be lowered by adsorbing sub- stances. This phenomenon is of particular significance for creep and fatigue breakdown of solids. This work of Rebinder has found application in a number of technological processes such as boring in solid rocks, grinding of the hard materials, and pressure processing and cutting of metals.

In 1946 he became Academician of the U.S.S.R. Academy of Sciences and Academician of the Kazakh S.S.R. Academy of Sciences. He was elected Chairman of the Presidium of the Kazakh S.S.R. Academy of Sciences in 1941 and was made Director of the Institute of Geological Sciences of the Kazakh Affiliate of the Academy of Sciences U.S.S.R. (reorganized in 1946 as the Kazakh S.S.R. Academy of Sciences). He has received a State Prize and the Order of Lenin three times. In 1951 Tadzhik S.S.R. Academy of Sciences made him an Honorary Member. In March 1962, Satpaev was elected delegate from Kazakh S.S.R. to the Supreme Soviet. As of 1961 he was a member of the Pre- sidium of the U.S.S.R. Academy of Sciences. Satpaev early developed an interest in the potential mineral wealth of his native Kazakhstan. After graduation he worked with the Dzhezkazgan Geological Prospecting Group, 1926-1941. During this period, Satpaev directed explorations of abandoned copper mining areas. Helped by young Kazakhs returning from mining courses in Leningrad, this group discovered one of the richest ore deposits in the world, that of Great Dzhezkazgan. Subsequently, he surveyed the Karsakpay iron ore deposits, twin of the Krivoy Rog deposits, and found lignite. From 1926- 1941 he also supervised a geological study of Tadzhik S.S.R. and found important ore deposits. He investigated various de- posits of iron, manganese, brown coal, and lignite. During the early period of the war, manganese for steel was in very short supply, due to the German occupation of Nikopol. Satpaev sug- gested finding manganese in Dzhezda and organized its dis- covery and mining in record time. During this period, the Kazakh Affiliate of the Academy of Sciences of the U.S.S.R. conducted 350 expeditions resulting in 160 practical proposals to the government. 325 SAUKOV His major work is devoted to the study of the geology and mineral species of Central Kazakhstan, particularly the study of mineral formations and their use in the national economy.

A number of investigations of Saukov deal with general questions of geochemistry, including ener- getics of natural processes and natural association of elements, problems of their migration, the geochemical methods of pros- pecting for deposits of commercial minerals. He is the author of a textbook. Geochemistry, which was translated into Bulgari- an, German, Chinese, Polish and Czech, Rumanian, Georgian. Bibliography: Geochemistry of Mercury. Moscow: 1946.

I. Sedov was born November 14, 1907. In 1931 he gradu- ated from Moscow University and in 1937 was appointed pro- fessor there. He began work in 1931 at the Central Aerohydro- dynamic Institute. In 1947 he started working at the Central Institute of Aviation Motor Building. Sedov is Chairman of the Interdepartmental Commission on Coordination and Control of Scientific Theoretical Research in the Area of Organization and Realization of Interplanetary Communication. In 1946 he was elected a Corresponding Member of the U.S.S.R. Academy of Sciences and in 1953 an Academician. The U.S.S.R. Academy of Sciences awarded Sedov in 1946 the Prize of S. A. Chaplygin. In 1952 he received a Stalin Prize. Sedov investigated various problems of mechanics. He de- termined the aerodynamic forces during a non- stabilized move- ment of the wings, in particular during vibrations. Sedov generalized the theorem of N. E. Zhukovskii for arbitrary mo- tion of the wing; formulated a mathematical method for solving problems of stream flow around wing profiles. This method was applied by him to the theory of a finite wing, and subse- quently widely applied in the theory of waves, in elasticity, and in filtration. In his treatise "Plane Problems of Hydrodynamics and Aerohydrodynamics," Sedov formulated a theory on gliding which was applied in hydroaviation and ship building. Sedov studied the impact of bodies against water, ricocheting and other problems of heavy liquid hydrodynamics. He developed a method for visualizing the stream line flow of gas past a grat- ing and worked out a method for investigating possible gas flows, widening the approximate method of S. A. Chaplygin. In the theory of similarity and dimensionality, Sedov constructed a theory of unstabilized gas motion, in particular the theory of dispersion of strong shock waves, obtained results on the theory of surface waves; established the law of pulsation in an iso- tropic turbulence. His work "Propagation of Strong Explosive Waves" (1946) is a study of strong shock waves. Sedov has also been concerned with problems of astrophysics.

During the years 1920-31, he worked at the Leningrad Physico-Technical Institute. He be- came Chief of the Institute of Chemical Physics of the U.S.S.R. Academy of Sciences in 1931 and subsequently the Director. In 1928 he was made professor at the Leningrad Polytechnic Insti- tute and in 1944 professor at the Moscow University. He was a Corresponding Member of the U.S.S.R. Academy of Sciences from 1929 until 1932 when he was elected Academician. In 1947 he became a member of the Communist Party of the Soviet Union. He was awarded a Stalin Prize in 1941, and in 1956 the Nobel Prize. Semenov' s first scientific work was in molecular physics and electron phenomena such as: vapor condensation on solid surfaces, the ionization of vapors of salts under the influence of an electron bombardment, and electric breakdown of di- electrics. And he also developed a thermal theory of the di- electric breakdown. The initial assumptions of this theory were utilized by Semenov in his theory of thermal explosions of gas mixtures. According to this theory, the cause of the ex- plosion is the unattainment of the heat equilibrium during 331 SEMENOV chemical reaction, because the heat liberated does not have time to leave the reaction zone. Semenov and his students studied energy distribution in a flame, detonation, and com- bustion of explosives and powders. The investigations of Seme- nov on the theory of chain reactions is particularly significant. On the basis of the study of critical phenomena, such as limit of ignition, observed during oxidation of vapors of phosphorus, hydrogen, carbon monoxide and other compounds, he discovered branching reactions. In his monograph, * Chain Reactions" (1934), he developed the theory of non-branching reactions and showed the wide distribution of chain reactions in chemistry. He and his associates developed theoretically and checked ex- perimentally many ideas of the chain theory: the breaking of reaction chains on walls and in the volume of a container, de- generate chain branching, positive and negative interaction of chains. Also, he established the detailed mechanism in a series of complex chain processes, and studied the properties of free atoms and radicals with the aid of which the elementary stages of these processes were realized. Semenov took active part in organizing a physico-mechanical department at the Lenin- grad Polytechnic Institute and in starting scientific journals. He trained many specialists in physics, chemical kinetics, and the combustion theory. In March 1962, Semenov was elected a delegate from R.S. F.S.R. to the Supreme Soviet. As of 1961, he was Secretary of the Department of Chemical Sciences of the U.S.S.R. Acade- my of Sciences. In 1961 he was elected Candidate Member of the Central Committee of the Communis* Party.

Academy of Sciences. Shaposhnikov has been an Academician of the U.S.S.R. Academy of Sciences since 1953. In 1949 he was awarded a Stalin Prize. Shaposhnikov' s main investigations are in technical micro- biology. While studying metabolism in microorganisms, he worked out a classification of energy processes which reflect processes of evolution of fermenting microorganisms. The in- vestigations of Shaposhnikov had considerable significance for organization and improvement of a number of industrial pro- cesses, which were based on the action of microorganisms. His studies of the physiology of lactic bacteria allowed him to work out an industrial scheme for producing lactic acid (the so- called protein method); investigations of butyric and acetic acid bacteria also led to the improvement of corresponding process- es. In 1929 Shaposhnikov undertook the study of acetone-butyl fermentation, at first in the laboratory and subsequently under semi-plant conditions. The process data obtained were used in planning and construction of the first U.S.S.R. Acetone -butyl plant. His work on the mobility of sap in plants found a practi- cal application in a new method of tapping pines. Bibliography: and others. New Tapping of the Pine Tree. Moscow: 1937.

He received his secondary edu- cation at the Nizhnii- Novgorod gymnasium, and his higher edu- cation at the Ekaterinoslav (now Dnepropetrovsk) Mining Insti- tute, from which he graduated in 1912 as a mining engineer. The mining graduation project on which he worked as a student was awarded the Kublin Prize, and his project on metallurgical mechanics was given an honorable mention. Following one year of work at the Donbas mines, he was enrolled as an assistant in the mining faculty of the Ekaterinoslav Institute, and in 1916, he was appointed a docent at the same faculty. After defending his dissertation in 1919 on the subject "Discovery of Hard Coal Deposits," he was awarded the degree of Mining Assistant (ad- junct) and, in 1920, he was appointed professor in the mining faculty. Shevyakov served during his graduate work and after, until 1928, as professor and director of the mining faculty of the Ekaterinoslav Mining Institute. In 1920-1922, he served with B. I. Bokii, A. M. Terpigorev, A. A. Skochinskii, and V. A. Guskov as a member of a Special Commission charged with the restoration of the Donbas hard coal and anthracite industry. After being sent on a mission by the VSNKh SSR (Supreme Coun- cil of the National Economy of the USSR) to Germany, U. S. A., SHEVYAKOV 342 England, and Scotland in 1925, he published a number of articles describing the status and trends of the development of the for- eign mining industries. From 1929 to 1932, he served as pro- fessor at the Tomsk Technological Institute; from 1932 to 1944, as professor on the mining faculty at the Sverdlovsk Mining Institute, and from 1944 to 1950, as professor and director of the faculty for the mining of blanket deposits at the Stalin Mos- cow Mining Institute. During these years, he served as permanent consultant and mining expert for numerous design establishments, main ad- ministrations, and individual mining enterprises, such as Donu- gol, Yugostal (Southern Steel Industry Trust), Soletrest, Kuz- basugol (State Association of the Hard Coal Industry of the Kuznetsk and Minusink Basins), Uralugol, Giproshakht (State Institute for the Design of Mine Construction in the Hard Coal Industry) and its Siberian affiliate, Gipromedruda (State Insti- tute for the Design and Planning of Copper Mining Establish- ments). During the restoration of the Donbas, he was in charge of a design group in Dnepropetrovsk, which conducted numerous designs of mines in the Donets Basin. He was directly con- cerned with the development of design projects for high- capacity mines in the Kuznetsk Basin, and he acted as consult- ant in working out design projects for coal mines in many regions of Siberia. The Ural affiliate of the Academy, which served the varied economy and industry of the Urals, expanded its scientific ac- tivities under his direction. During World War II, Shevyakov conducted extensive work in the Commission for mobilizing the resources of the Ural region. Western Siberia, and Kazakhstan to serve defense requirements. In 1942, Shevyakov, with A. A. Skochinskii, worked to restore the Donets and Moscow Basins destroyed by the Germans. In January 1942, he worked in the town of Karpinsk, where he determined the possibility of ex- panding coal production from the Bogoslovsk deposits in the Urals. In May 1942, he worked at the Ural Aluminum Plant in connection with the expansion of Bauxite production in Kamensk Region; in June-July 1942, he was in Kazakhstan where he in- creased coal production, ore production, and the smelting of metals. In September 1942, he worked in Korkino and Kopeysk where he served as consultant on a number of technical prob- lems concerning the development of coal extraction by the open pit method. In February -March of 1943, he was a member of the com- mission entrusted with the determination of the status of the 343 SHEVYAKOV available ore reserves supplying the Kuznetsk metallurgical plants, the determination of the production capacities of mines in the Kuznetsk Basin, and the improvement of power facilities in industrial centers of Western Siberia. In August-September of 1943, he was engaged in similar work in Krarganda. He worked in the Commission of the Peoples' Commissariat for the Coal Industry, which was charged with the establishment of rational systems for the extraction of the rich coal beds located at the Prokopyevsk-Kisel region of the Kuznetsk Basin, as well as the increased production of coking coal in the Osinovsk region. Almost immediately after the Mining Institute moved back to Moscow, Shevyakov worked there in establishments subordinate to the U.S.S.R. Academy of Sciences. During the past 20 years, he was a member of the Presidi- ums of Technical Councils in the Ministry of the Coal Industry, the Ministry for the Building of Coal Enterprises, the Ministry of Nonferrous Metallurgy, and frequently served as the chair- man of expert commissions to study important coal and ore mining technical problems. In 1943, he was appointed a member, and in 1946, director of the Council for Scientific and Technical Consultation under the Gosplan (State Planning Commission of the USSR), which discussed the most important problems concerning the regional distribution and development of industry. From 1947 to 1957, he was a member of the Gosplan of the U.S.S.R. He has actively participated in All- Union Conferences, and works for close contacts between Soviet mining scientists and personnel em- ployed in industry and in design and training institutes located in outlying districts. He is an active member of the All- Union Society for the Dissemination of Political and Scientific Know- ledge. From 1947 to 1950, he served as a delegate of the Second Moscow City Council of Workers' Deputies; for many years, he was elected a member of the Orgbyuro (Organization Bureau) of the All- Union Scientific -Technical Mining Society. From 1941 to 1944, he served as president of the Orgbyuro of this society, and from 1953 to 1955, he acted as director of the section for underground mining of coal deposits. Shevyakov is a member of the editorial boards of the follow- ing scientific-technical journals: Izvestia An SSSR, Otdelenie tecknicheskikh nauk (Bulletin of the USSR Academy of Sciences, Division of Technical Sciences), Ugol (Coal), Gornii Zhurnal (Mining Journal), ByuUeten ITEIN (Bulletin of the Institute of Technical and Economic Information); he is also a member of SHEVYAKOV 344 the editorial council of Ugletekhizdat (State Scientific and Tech- nical Publishing House of Literature on the Coal Industry). He has frequently served as president of juries for AU- Union contests involving the best design project of mining sys- tems adapted to various conditions of complex mechanized equipment used on mine surfaces. He also constantly takes part in the examination and evaluation of projects submitted in competition for Lenin prizes, acting in the capacity of presi- dent of the mining and metallurgical section, and as a member of the Committee. In 1939, he was elected an Academician of the U.S.S.R. Aca- demy of Sciences, appointed Deputy Director of the Ural affili- ate of it, and Director of the Mining and Geological Institute of the affiliate.

V. Skobel'tsyn was born November 24, 1892. After gradu- ating from Petersburg University in 1915, he worked in the Polytechnic and Physico-Technic Institute in Leningrad. Subse- quently he was at Moscow University and the Physics Institute of the U.S.S.R. Academy of Sciences. In 1951 he became Di- rector of this Institute. He was a Corresponding Member of the U.S.S.R. Academy of Sciences from 1939 to 1946 when he was elected Academician. Skobel'tsyn has been active in public affairs also. He was Deputy to the U.S.S.R. Supreme Soviet and a member of the Commission on Foreign Affairs of the Soviet Union. In March 1962, he was re-elected a delegate from Ural SSR to the Supreme Soviet. In 1950 he was made Chair- man of the Committee on the International Lenin Prize " For Strengthening Peace Between Peoples." He was awarded a Stalin Prize in 1951 and in 1952 the gold medal of S. L Vavilov by the U.S.S.R. Academy of Sciences. Skobel'tsyn carried out research in nuclear physics and cosmic rays. In 1923 he began research on the phenomena of interaction of substance with gamma rays from radium. In order to clarify the mechanism of these phenomena, Skobel'tsyn used the Wilson cloud chamber, with the aid of which he was able to view directly and photograph the recoil electrons knocked out by collisions of high energy photons (gamma rays) with gas atoms which filled the chamber. These studies gave direct support to the quantum character of the Compton effect. Subsequently Skobel'tsyn utilized these phenomena for studies SKRYABIN 356 in gamma rays spectroscopy. The method proposed by Skobel'- tsyn of using the Wilson cloud chamber in a magnetic field has been widely used for studying beta and gamma rays spectra and for basic investigations of properties of elementary particles. In 1927-29 Skobel'tsyn studied cosmic rays. In the postwar years, he carried out research on the study of cosmic ray showers. In November 1962 Skobel'tsyn received the Order of Lenin.

In 1905 he gradu- ated from Yur'ev Veterinary Institute and until 1911 worked as a veterinarian in Central Asia. He was professor at the Don Veterinary Institute in Novocherkassk from 1917 to 1920 when he became professor at Moscow Veterinary Institute (now the Moscow Veterinary Academy). Also in 1920, he was made Chairman of the Helminthological Department of the State Insti- tute of Experimental Veterinary Sciences which he originally organized and then, in 1931, reorganized into the AU-Union Institute of Helminthology. Skryabin has been the Director since its founding. He was Chairman in 1921 to 1949 of the Helminthological Department of the Tropical Institute (now the Institute of Malaria, Medical Parasitology and Helminthology) founded by him. In 1942 he became Chief of the Laboratory of Helminthology of the U.S.S.R. Academy of Sciences. Skryabin was elected an Academician of the U.S.S.R. Academy of Sciences in 1939 and in 1944 a member of the U.S.S.R. Academy of 357 SKRYABIN Medical Sciences. In 1943 to 1952 he was Chairman of the Pre- sidium of the Kirghiz Branch of the U.S.S.R. Academy of Sci- ences. A member since 1935 of the Lenin All- Union Agricultur- al Academy, he was elected President in 1956. Skryabin is well known for his public activities also. He has been Deputy of the U.S.S.R. Supreme Soviet, second and third convocations. In 1922 he found and chaired the Commission of the Study of Hel- mintho Fauna of the U.S.S.R. and in 1940 reorganized it into the All- Union Society of Helminthologists of the U.S.S.R. Academy of Sciences of which he is currently President. He participates in domestic and international zoological and veterinary con- gresses and is a member and honorary member of several foreign scientific research organizations and societies. In 1927 he was an Honored Scientist of the R.S.F.S.R. Twice, 1941 and 1950, he was awarded Stalin Prizes. The Academy of Sciences of the U.S.S.R. awarded Skryabin the Gold Medal of I. I. Mechni- kov in 1949. In 1954 he was an Honored Member of the Kirghiz S.S.R. and in 1958 a Hero of Socialist Labor. In 1957 he won a Lenin Prize. The AU-Union Institute of Helminthology in Mos- cow and the Kirghiz Agricultural Institute in Frunze are named for him. The investigations of Skryabin are in morphology, biology, phylogeny and systematics of parasitic worms, epidemiology (epizootology) and organization of measures to control helmin- • thosis of man and domestic animals. Under the leadership of Skryabin there were conducted about 300 helminthologic expe- ditions in various regions of the U.S.S.R. He introduced (with R. S. Shul'ts) the concept of additional reservoir and transit hosts and gave an analysis of the processes of migration of various bladder worms in the bodies of a host; he introduced the concept of geo- and biohelminthosis, the concept of de- helminthization, devestation. The many instruction and refer- ence books on control of helminthosis published by Skryabin are widely utilized in medical and veterinary practice. He outlined about 200 new types of bladder worms. As of 1961, Skryabin was a Vice-President of the Lenin AU- Union Agricultural Academy. Bibliography: and R.-Ed. S. Shul'ts. Helminthosis of Horned Cattle and Its Young Stock. Moscow: 1937. and R.-Ed.

From 1912 to 1930 Smirnov was professor at Peters- burg Institute of Engineers of Means of Communication. He received the degree of Doctor in Physical-Mathematical Sciences in 1936. He worked from 1929 to 1935 in the Seismological and Mathematical Institutes of the U.S.S.R. Academy of Sciences. In 1932 he was elected a Corresponding Member of the U.S.S.R. Academy of Sciences and in 1943 an Academician. He was awarded a Stalin Prize in 1948. Smirnov has worked primarily in theory of a function of a complex variable such as the uniformization of the many-valued analytical functions, the investigation of Fuchsian groups and Fuchsian functions in the presence of an infinite number of substitutions of corresponding groups, the reversal of a differ- ential equation of the Fuchsian type with four singular points. In a series of investigations conducted with S. L. Sobolev, SMIRNOV 360 Smirnov worked out a new method of solving some problems on the theory of the propagation of waves in elastic media with plane boundaries. He investigated the singular solutions of a wave equation and the equations for elasticity, and in connection with this, put forth a new method for investigating the oscil- lations of an elastic circle and sphere for a given external influence. For linear equations of elliptical type, with any number of variables, Smirnov studied cases when these equations allow functionally invariant solutions. This investi- gation was based on a concept introduced by Smirnov of conju- gated function for Euclidian space or Riemannian space with a positive metric. Smirnov is the author of Course in Advanced Mathematics (5 volumes), 1924-47. He trained a large number of students.

In 1941 he was awarded a Stalin Prize. 363 SOBOLEV Sobolev has studied the dynamics of an elastic body. He formulated the theory of plane waves in an elastic semi -space with a boundary free from tension, and elucidated the general concept of a surface wave. Together with V. I. Smirnov, he worked out a new method of investigating the propagation and reflection of elastic waves from rectilinear boundaries— a method which is associated with functionally invariant solutions of wave propagation on a plane. Sobolev also worked out a new method of integrating linear and non-linear equations with partial derivates of the hyperbolic type. He carried out re- search on the boundary problem in an n-dimensional space for poly-harmonic equation in the presence of a degenerate bounda- ry; he established an almost-periodic solution of the boundary problems of linear hyperbolic equations, investigated the de- pendence of the solutions of hyperbolic equations on disturbing forces, initial and final conditions, and solved new boundary problems for these equations. In his investigation Sobolev formulated a series of new concepts; generalized derivative, generalized solution of equations with partial derivatives, generalized differential operator. With the aid of these con- cepts, he was able to formulate and solve some fundamental problems in mathematical physics. Future development of these ideas of Sobolev led to the establishment of the theory of the so-called generalized functions. Sobolev also studied the properties of functional space. As of 1961, Sobolev was a Member of the Presidium, Siberi- an Branch U.S.S.R. Academy of Sciences, and Director of the Institute of Mathematics and Computation Center, Siberian Branch U.S.S.R.

In 1936, his monograph, * Pet- rology of the Traprocks of the Siberian Plateau" was accepted as his doctoral dissertation, and he received the title of pro- fessor. In 1951, he was elected Corresponding Member of the Ukrainian Academy of Sciences, and on March 28, 1958, he was elected Academician of the U.S.S.R. Academy of Sciences. He is currently a member of the Council and the Editorial Council of the Lvov Geological Society. He received a Stalin Prize in 1949. Sobolev started his research as a student first in 1928 in the Geological Committee and then in the Central Scientific Re- search Institute of Geological Survey and the All -Union Geo- logical Scientific Research Institute. He began his investi- gations in the Ukraine in 1936 and continued them in 1945, following his transfer to the University of Lvov. He has been teaching since 1931. In 1931-41 and 1942-45, he was employed by the Leningrad Mining Institute and in 1939 was made pro- fessor. He also taught in the University of Irkutsk from 1941- 45. From 1943 to 1945, he served as Director of the Mineral- ogy Department of the Leningrad Mining Institute and as Di- rector of the Fedorov Institute. In 1945, he joined the University of Lvov as chairman of the Petrography Department. In 1947, he began working at the Institute of the Geology of Minerals in the Ukrainian S.S.R. in Lvov. Sobolev is the author of over 100 scientific papers dealing chiefly with three subjects: petrography and mineralogy of Siberia, petrography and mineralogy of the Ukraine, and theo- retical aspects of mineralogy and petrography. He has devoted many years to the study of the traprock of the Siberian Plateau. He demonstrated that the formation of various rock minerals is associated with the crystallization differentiation whose sensi- tive index is the FeO:MgO ratio. His study of the mineralogy of Siberia gave the first description of a rare paragenesis of the contact calcium silicates — spurrite, merwinite, cuspidine. In addition, he has discovered and described the magnetite de- posits in the Ilimpeya River. In his monograph on traprock, Sobolev furnished a survey of the corresponding formations of the earth's crust, stressing the similarity of the Siberian plateau geology to that of the Karoo plateau (South Africa). This analogy became more conclusive 365 SOBOLEV when in 1937, having analyzed some petrographic samples col- lected by N. N. Urvantsev from the Taimir Peninsula, he suc- ceeded in finding a unique basic rock resembling the ultrabasic type. He concluded that this rock may be an analog of the South African basic formations (melitite basalts) which accompany the kimberlites. He also advanced the hypothesis concerning the diamond-bearing potential of the northern Siberian plateau. This hypothesis was confirmed first through the study conduct- ed jointly with A. P. Burov of the geology of diamond deposits in foreign countries, and by the discovery of extensive areas of basic vulcanic rocks in Khatangi District. Rock samples from this district were collected by members of the Arctic Institute Expedition and tested by G. G. Moor in consultation with Sobo- lev, whereupon Moor confirmed the hypothesis on the occurrence of diamonds. In his report for 1940 to Gosplan S.S.S.R. (State Planning Committee of the U.S.S.R. Council of Ministers) he wrote: "The Siberian plateau has the greatest coincidence with the kimberlite deposits of South Africa. This coincidence is amplified even more by the discovery by the author, on the Taymir Peninsula, and by G. G. Moor (in consultation with the author) in the Khatangi River area, of basic rocks of the lim- burgite, augite, and alnoite type, resembling the South African melitite basalts which accompany kimberlites. Each expedition operating in the northern Siberian plateau should give serious attention to prospecting for diamonds. It is especially im- portant to diamond prospecting in the active placers of precious metals in the Norilsk area and in Vilyuy." Thus, V. S. Sobolev predicted the location of diamond kimberlites not only in the northern Siberian plateau generally, but also in the Vilyuy area in particular. After the discovery .of kimberlites, Sobolev was invited to take part in the expedition. He paid visits to diamond deposits (1955), advised in petrographic and mineralogical analysis of the materials, and jointly with A. ^P. Burov served as the scien- tific editor of the first book on diamonds in Siberia. Of Vladimir Stepanovich's writings on the petrography of the Ukrainian S.S.R.,one must mention first of all the monograph on the petrology of the complex Korosten pluton which he feels to have a direct connection with the petrology of traprock for- mations. In this book the author once again stresses the im- portance of the study of femic minerals of magmatic rocks. He distinguishes the most important differences between the plateau type of granites and those of folded areas, which are the result of varying ferruginosity in femic minerals. He was the first to SOBOLEV 366 find basic syenites and new deposits of piezo-electric crystals in this region of the Ukraine. In post-war years, Sobolev has devoted much of his time to the study of young volcanic rocks in the Carpathian Mountains. Explorations in this region are being conducted jointly with a group of his students. In his writings on the mineralogy and petrology of the Ukrainian S.S.R. he described the ultra- basic rocks of Transcarpathia and established, within the meta- morphic complex of this region, the occurrence of diaphtoresis; he has described a new find of pumpellyite from the Carpathian Mountains, pointing out the identity of this mineral to lotrite and others. Sobolev is not only a petrographer but a mineralogist as well. He has published since 1944 a series of articles on the theoretical mineralogy of silicates, and in 1949 a book entitled Introduction to the Mineralogy of Silicates which was awarded a Stalin Prize, Second Class. In this treatise he attempted to make an interrelationship between the properties and genesis of minerals, on the one hand, and silicates and their crystal structure on the other. He has established a connection between the difference in ionic radii in isomorphic series and the type of fusibility curves; substantiated A. E. Fersman's ideas re- specting the regularity of isomorphism; determined the re- lationship between the change in the coordinate number of alumi- num during mineral formation and the physico-chemical equilibrium factors; clarified the relationship between the opti- cal properties of silicates, including their color, and their structure. Moreover, he has generalized the data of paragene- sis of igneous rocks in the form of multi -fascicular diagrams. Certain structural features of various silicates, which had been predicted by V. S. Sobolev on the basis of mechanisms which he had evolved, have been verified by X-ray analysis. Thus, for example, the investigations conducted by N. V. Belov and I. M. Rumanova have corroborated his hypothesis concern- ing both the six-fold coordination of aluminum in epidote and the presence of a diortho group in the latter. Studies by Chinese authors have supported his hypothesis concerning the two types of coordination of aluminum in prehnite and others, ite and others. Maintaining in his studies that hydroxyl in many silicates cannot substitute oxygen in oxysilicic tetrahedrons, V. S. Sobo- lev proposed in this connection a new way of computing the crystallo- chemical formulas of water -containing silicates. In 1949, he was the first to advance the hypothesis concerning the 367 SOBOLEV substitution of the potassium ion in micas with the oxonium ion. Sobolev has written a number of articles on theoretical pet- rography: metamorphism, formation of igneous rocks, granit- ization, genesis of lamprophyres, mineral formation at oriented pressure. He stresses the importance of studying femic miner- als of rocks and proposes certain simplified diagrams which facilitate the approximate determination of biotite and horn- blende (by their optical properties) in granitoids. Of special value are the tables of optical orientation of minerals which have been published as a supplement to the text Fedorov Method. Bibliography: Petrology of the Siberian Platform.

Academy of Sciences in 1946, and in 1953 an Academician. In 1948 he was awarded a Stalin Prize. Strakhov' s scientific activity is in the field of modern de- posits, ancient sedimentary rock— iron ore, lime-dolomitic rocks, oil shale, halogen deposition, and of the geochemistry of iron, manganese, phosphorus, vanadium, chromium, nickel, and a series of other elements. Continuing the work of his teacher, A. D. Arkhangel' skii (1879-1940, geologist, professor at Mos- cow University, and Academician), Strakhov developed and es- tablished a comparative method of analysis in lithology. A study of contemporary reservoirs (Black and Caspian Seas, Lake Aral, Balkash and others) was made and an exact analysis of contemporary sedimentation was presented. He studied the role of diagenesis in the formation of sedimentary rock. He published monographs on iron ore and lime-dolomitic species of modern and ancient reservoirs and discovered new regulari- ties in the formation of iron and carbonate rocks. He defined the characteristics of sedimentation by the main structural units of the earth's crust— platforms, geosynclines and the fore- most depressions. He suggested a scheme of irreversible evo- lution in sedimentary rock formation during the history of the earth, and indicated three important stages: Pre-Cambrian, the Proterozoic-lower Paleozoic, and the modern (from the Devonian to the present). In addition, he associated the peri- odic recurrence of similar rocks with the recurrence of major transgressions and regressions of the sea. Recently he 379 STRELETSKII has advanced the idea that four types, ice, humid, arid and sedi- mentary, are involved in sedimentary rock formation. In 1960 Strakhov was awarded the Red Banner of Labor. Bibliography: Domanik Facies of Southern Urals. Moscow: 1939. Iron Ore Facies and Their Analogies in the Earth's History. Moscow: 1947.

Beginning in 1934, he has worked at the Physics Insti- tute of the U.S.S.R. Academy of Sciences. Tamm was a Corre- sponding Member of the U.S.S.R. Academy of Sciences from 1933 until 1953 when he was elected an Academician. He was a Hero of Socialist Labor. In 1958 he received a Stalin Prize and also the Nobel Prize. All of Tamm's students are well known physicists and theoreticians. Tamm's theoretical investigations are in quantum mechanics and its applications, in radiation, in cosmic rays, and inter- action of nuclear particles. In 1932 he formulated a quantum theory on the scattering of light in solid bodies and developed the relativistic quantum mechanics theory of light scattering by electrons. In the quantum theory of metals, Tamm and S. P. Shubin gave a theory of the photoeffect in metals in 1931. In 1932 he predicted the existence of special surface states of electrons on crystals known as the Tamm levels. In 1934 he developed mathematically a quantitative theory of nuclear forces based on exchange interaction of electrons and neutrinos. In 1937 he and I. M. Frank worked out the theory of Cherenkov ef- fect, the radiation emitted by a rapidly moving electron. For this work he received the Nobel Prize. In 1945 he gave an ap- proximate method for calculating the interaction of nuclear elementary particles. Tamm, with A. D. Sakharov, proposed in 1950 the utilization of an electric discharge in plasma, which is placed in a magnetic field, for obtaining a controlled thermo- nuclear reaction. Tamm is the author of a textbook. Basis of the Theory of Electricity (1929, 6th ed., 1956). Tamm has attended the Pugwash Conferences.

Terenin' s main works are devoted to study of the nature of physical and chemical processes which take place in substances under the influence of light. For discovering and analyzing these processes Terenin worked out optical methods which are based on observation of spectra and the intensity of lumines- cence of primary products of photoreactions. He showed the possibility of selectively exciting emission of atomic spectral lines of metal vapors and analyzing the energy level distri- bution. Terenin studied the dissociation of salt molecules in a vapor state under the influence of light which is accompanied by formation of luminescent atoms (1924). In this way he in- vestigated many polyatomic molecules of inorganic and organic compounds by irradiating them with a short-wave ultraviolet radiation (1936). Terenin used fluorescence of aromatic mole- cules in a vapor state for establishing the mechanism in the intramolecular and intermolecular transformations of energy of excitation (1934). In 1943 he explained the phosphorescence of molecules of complex organic compounds, and of their photo- chemical reactions based on excitation of molecules into a state with two unpaired electrons (biradical). He was the first to ob- tain infra-red spectra of gases at several thousand atmos- pheres (1940). Terenin studied the optical properties of mole- cules, adsorbed on the surface of solid bodies and the nature of catalyst activity (1934). In 1945 he studied the photochemical reactions of chlorophyl and its analogs. In the 1950' s Terenin was investigating reactions of organic molecules by using light to ionize electrons. Terenin is the leader of the school of Soviet photochemists.

N. Tupolev was born October 29, 1888. In 1909 he entered Moscow Higher Technical School where he was a pupil of N. E. Zhukovskii, founder of Russian Aviation. While still an under- graduate, he designed the first wind tunnel. Tupolev also par- ticipated in the work of the aeronautical group of the Moscow Higher Technical School and designed and built training gliders, in one of which he became a pilot. After his graduation from the Moscow Higher Technical School, he assisted in the organi- zation of the Central Aerodynamic Institute and from 1918 to 1935 was the Director. Tupolev is a Lieutenant General in the Engineer-Technical Service. In 1933 he was elected Corre- sponding Member of the U.S.S.R. Academy of Sciences and in 1953 Academician. He was made an Honored Scientist of the R.S.F.S.R. in 1933 and a Hero of Socialist Labor in 1945. Tupo- lev was awarded a Stalin Prize and, in 1957, a Lenin Prize. He has been a Deputy of the Supreme Soviet (third through fifth convocations). In 1922, a bureau of design, in the Central Aerodynamic Institute, under the direction of Tupolev, designed and con- structed the single-seat ANT-1, built wholly of wood. In 1923- 24, Tupolev designed a glider, a hydroplane, and the two -seat airplane, ANT-2, made entirely from duraluminum. Under his direction, more than 100 various types of airplanes were de- signed and constructed. Tupolev also designed and constructed medium and heavy bombers: TB-1, ANT-9, TB~3, ANT-25 (RD), TB-7, SB, TU-2, TU-4, TU-104, and the TU-114. In planes designed by Tupolev, a series of Russian flights were carried out in Europe and to America (flights of V. P. Chkalov and M. M. Gromov across the North Pole in an ANT-25 air- plane), landings of polar expeditions on drifting ice floes, the rescue of the crew of the steamship "Chelyuskin," and other im- portant tasks were accomplished. Tupolev airplanes were used for attacking enemy objectives at long distances. The TU-104 (1955) is the Soviet jet airplane. Its cruising flight speed: 800 kilometers/hr. The cabin of the airplane is 405 USHAKOV hermetically sealed, which permits use of flight altitudes at 10,000 meters. Through further improvement of this type of aircraft, there appeared the more comfortable, multi-seat (170) passenger airplane, the TU-114 (1956) with turboprop engines. Continuing the work of N. E. Zhukovskii, Tupolev worked on aerodynamic calculation for airplanes and on the strength of material. Besides the designing of airplanes, Tupolev con- structed various types of naval torpedo boats. In March 1962, Tupolev was re-elected Deputy from R.S.F.S.R. to the Supreme Soviet. He has attended Pugwash Conferences.

In 1943 he be- came a Corresponding Member of the Academy of Sciences of the U.S.S.R., and since 1953 he has been an Academician. He was made, in 1949, a hero of Socialist Labor. Vinogradov graduated from the Medical Military Academy and Leningrad University in 1924. He was a pupil and close collaborator of B. I. Vernadskii, the founder of the Russian School of Geochemistry. In 1948 he became Director of the Institute of Geochemistry and Analytical Chemistry, U.S.S.R. Academy of Sciences. Both in 1949 and 1951, he was winner of Stalin Prizes. His fields of interest are the distribution of chemical ele- ments in the upper part of the earth's crust, the investigation of primary rock from which the sedimental part of the earth's surface was formed, and the role played by vulcanic materials in the formation of this upper part. While studying the salts in the ocean, he came to the conclusion that cations of the sea water are products of the erosion of magmatic rocks and that anions are of vulcanic origin. Vinogradov has worked predominantly with rare and widely dispersed chemical elements. In geochemistry of the individual elements (halogen, boron, strontium, etc.), he emphasized the importance of knowing, not only absolute amounts of the ele- ments but also the ratios of the closely related elements, as that of chlorine to bromine or strontium to calcium. He de- scribed geochemically more than forty rare and widely dis- persed elements for different soil zones and showed their roles VINOGRADOV 416 in various soil-forming processes. He has investigated the association of heavy metals such as vanadium and nickel with bitumen. He has been active in the use of isotopes (sulfur, hydrogen, ox>^gen, carbon, etc.) in geochemistry and has used ox>'gen isotope Ol8 as an indicator of geochemical processes. In photosynthesis, he found that plants liberate oxygen from water and not from carbon dioxide. Also he showed that natural hydroxides of iron, manganese, etc. obtain oxygen from water rather than from the air. In the biogeochemical field, he in- vestigated the changes produced by surroundings in the chemi- cal composition of marine organisms. He found that the ma- jority of chemical elements exist in all the organisms and that elemental chemical composition of a species is its character- istic feature. Vinogradov also developed a theory of biogeo- chemical regions and by his study of areas with deficient and excessive content of chemical elements, he evolved a theoreti- cal basis for ordinary fertilizers and those containing micro- elements. His investigations in biogeochemical regions also explained the effect of the chemical environment on the evo- lution of flora and fauna during different geological ages. In analytical chemistry, Vinogradov developed many methods of separation of numerous stable and unstable chemical elements and introduced instrumental methods of analysis such as po- larography, spectrometry, radiometry, mass spectrometry, x-ray, and luminescence. As of 1961, Vinogradov was Director of the Siberian Branch U.S.S.R. Academy of Sciences Institute of Geochemistry and of the U.S.S.R.

In 1947 he was made professor at Moscow University. He has been an Academician since 1946. With E. I. Zhukovskii he made a study of electrothermal distillation of phosphorus from native phosphates in 1922. On the basis of this study, electric furnace plants were built for the first time in the U.S.S.R. From 1923 to 1929, he supervised the production of superphosphates from native phosphates and apatites. He worked also on the acid conversion of phosphates to concentrated fertilizers. Then he developed a process for obtaining potassium salts from sylvinite. In 1926, Vol'fkovich and his co-workers worked out a coordinated treatment of phos- phates with nitric acid to obtain phosphorus, nitrogen, and com- plex fertilizers, fluorine salts, and rare earths. For this work he received a Stalin Prize in 1941. In 1930 and 1931 with A. P. Belopol'skii, he studied a physico-chemical treatment of mira- bilite to obtain soda and ammonium sulfate. Vol'fkovich initiat- ed a number of studies on crystal chemistry of ammonium ni- trate. And he also proposed a method of obtaining boric acid from native datolites. With co-workers he developed a hydro - thermal method of phosphate treatment. From 1945 to 1950, he worked out new methods for obtaining fluorine compounds, am- monium nitrates and sulfates, phosphides, chlorides, and phos- phorus compounds. He also developed procedures for obtaining a number of metallo organic compounds.

After gradu- ating from Leningrad University in 1932, he worked in the Urals Physico-Technical Institute in Sverdlovsk. In 1939 he began working in the Institute of Physics of Metals in the Urals branch of the U.S.S.R. Academy of Sciences, now U.S.S.R. Academy of 423 VONSOVSKII Sciences, and in 1944 he was also a professor at Urals Uni- versity. Since 1953 he has been a Corresponding Member of the U.S.S.R. Academy of Sciences. In order to explain the electrical and magnetic properties of metals and semiconductors, Vonsovskii (with S. Shubin) de- veloped the so-called "polar" and (s-d) exchange theories, treating the system of electrons in a crystal lattice as a single interacting system. Besides the processes of exchange, he also took into account transfer processes, which lead to the estab- lishment of polar states. On the basis of these models, Vonsov- skii and associates constructed a general theory on ferro- magnetics close to the Curie point, and explained fractional atomic moments, the optic, magnetooptic, electric and other phenomena in ferromagnetics, an indirect exchange in ferrites, and the general theories of transition metals with magnetic atomic orders.

After graduating from Moscow University in 1915, he worked in several scien- tific research organizations. From 1927 to 1935, he was at the All- Union Electrotechnical Institute where he was made pro- fessor in 1929. He worked at the Physics Institute of the U.S.S.R. Academy of Sciences from 1941 until 1944. Wweden- sky, in 1941-1944, served as a member of the Presidium of the U.S.S.R. Academy of Sciences. In 1944-1951 he was Chairman of the Section on Development of Problems in Ffadioengineering of the U.S.S.R. Academy of Sciences and, in 1946-1951, he was Academician Secretary of the Department of Technical Sciences of the U.S.S.R. Academy of Sciences. He became a member, in 1949, of the main editorial board and the chief editor, in 1951, of the Great Soviet Encyclopedia. Since 1959, he has been Chairman of the Scientific Council of the Soviet Encyclopedia. In 1953 he began working at the Institute of Radioengineering and Electronics of the U.S.S.R. Academy of Sciences. Wweden- sky was elected Corresponding Member of the U.S.S.R. Academy of Sciences in 1934, and in 1943 Academician. In 1954 he be- came a Corresponding Member of the German Academy of Sci- ences, Berlin. He has received the following awards: in 1949 the Gold Medal of A. S. Popov; in 1952 the State Prize; in 1945 and 1953, the Order of Lenin; in 1953 and 1962, the Red Banner of Labor. Wwedenskii's main work is concerned with the study of the propagation of ultra-short waves, and also with investigations in magnetism. Under his leadership an ultra-short wave broad- casting station (RV-61) was built in 1929. In 1932-1933 he organized expeditions for the study of the propagation of meter and decimeter waves over the sea surface. The expedition proved the possibility of the propagation of ultra short waves beyond the horizon (diffraction propagation) and allowed a de- termination of the relationship between the propagation of ultra short waves and meteorological conditions (phenomenon of re- fraction). Wwedensky introduced the "diffraction formula," 427 WWEDENSKY according to which the field of ultra short waves beyond the horizon could be calculated (1935-1936). Wwedensky's publi- cations on the propagation of ultra short waves are: Basis of the Theory of Propagation of Radiowaves (1934); Propagation of Ultra Short Waves (1934); Propagation of Ultra Short Waves (1938; together with A. G. Arenberg). His investigations in magnetism are presented in the monograph, Contemporary Study of Magnetism (1929; together with Academician G. S. Landsberg).

In the Donbas, from 1892, he partici- pated in a geological survey conducted by the Geological Com- mittee and studied the structure of the Bakhmut salt-bearing basin. He worked out and paleontologically substantiated the stratigraphy of lower Permain sediments. In the Urals, Yakov- lev conducted geological investigations on deposits of coal, iron and other ores; the Caucasus and territories beyond the Cau- casus, he studied various mineral sources. He was the first to. make paleoecological investigations of invertebrates in Russia, particularly of the three Paleozoic groups of animals— brachio- pods, tetracorals and pelma echinoderms. He investigated the origin of structural festures of organisms and the change of these features under the influence of external factors. Bibliography: Studies on the Coral Rugosa.

Yanshin was born March 28, 1911. In 1923 he gradu- ated from Moscow Geological Survey Institute and had been working since 1929 in the Mining-Geological Department at the Scientific Institute for Fertilizers. From 1936 he worked at the Geological Institute of the U.S.S.R. Academy of Sciences and in 1956 was made Chairman of the Department on Regional Tec- tonics at this Institute. Yanshin was elected an Academician of the U.S.S.R. Academy of Sciences in 1958. In 1953 he was awarded the A. P. Karpinskii Prize for his work on "Geology of the North." He was the recipient of three orders and also some medals. Yanshin' s investigations are in tectonics, stratigraphy, lith- ology, and hydrogeology primarily of the Western territory of the Kazakh S.S.R., and of the Southern Urals. In the Southern Urals, he located a wide development of continental Mesozoic sediments and distinguished in them a series of formations. He worked out the stratigraphy of Tertiary sedimentation of the Aralo-Turgaisk depression, in connection with which he criti- cally examined some general questions in paleogenic stratigra- phy. In biostratigraphic examinations, he adhered to the idea of 431 YUNUSOV non- simultaneous appearance and disappearance of the same or similar species in dissimilar zoophyto- geographic territories. In tectonics he studied so-called "young" platforms with a Paleozoic folded base. In particular, he suggested new ideas on folded structures of the Urals, Tien Shan, and Mangishlak, and of the deep geological structure of the plains surrounding the Aral Sea. The presence of oil deposits in this territory was predicted by Yanshin. He took part, in 1952 and 1956, in the compilation of tectonic maps of the U.S.S.R. He studied lig- nites, iron ores, bauxite, phosphorite, potassium salt, and cement raw materials, and he discovered industrial deposits of these minerals. He also found a series of artesian basins.
