READ BEFORE THE NATIONAL ACADEMY OF SCIENCES November 16, 1904. < BIOGRAPHICAL MEMOIR OF CHAS. EMERSON BEECHER, CHARLES EMERSON BEECHER, eldest son of Moses and Emily (Downer) Beecher, was born in Dunkirk, New York, October 9, 1856. ? The mother of Moses Beecher was a Dawson, originally from England. On the Emerson side, the great-grandfather of Charles, Richard Emerson, was from Spofford, New Hampshire, and his wife was Mary Gorton, a direct descendant of Samuel Gorton, of Rhode Island. They moved to Otsego county, New York, in 1749. Moses Beecher was a banker, and is remembered as a courtly gentleman of the old school, a man of education and refinement. He and his wife were considered persons of more than ordinary cultivation and attainments. Five children, four boys and a girl, were born to them, of whom one brother survives in Cali- fornia. In the early childhood of Charles his parents removed to War- ren, Pennsylvania, where the boy attended private grammar and the public high schools. The surroundings were favorable, the rocks of the vicinity rich in fossils, and at the age of twelve years he began making a collection of the local fossils. Perhaps, as he was always delicate, his parents may have encouraged him as a means of keeping him as much as possible in the open air. At all events, he became much interested, and amassed from the Chemung and Waverley formations of Warren a choice and ex- tensive collection. These tastes soon led him to extend his studies to the minerals and recent shells, in which he always remained interested. Later he took the scientific course at Michigan University, receiving in 1878 the degree of B.S. from that institution. The late Prof. James Hall, of Albany, kept a watchful eye on all students and collectors of fossils, and, after graduation, young Beecher went to Albany almost immediately, where he was en- gaged as assistant in the New York State Museum directed by 59 NATIONAL ACADEMY OF SCIENCES. Professor Hall, and affording unrivaled opportunities for the study of American paleozoic invertebrates. During the ten years spent here by young Beecher he not only became proficient to a remarkable degree in knowledge of the New York faunas, but, having a natural facility in mechanical matters and the use of tools, he became an exceptionally fine preparator of fossils, and always enjoyed the process of disentangling a complicated fossil from its matrix, or the revelations of the saw in making serial sections. Some of the preparations of groups of trilobites left by him in the State Museum are marvels of well-directed and successful effort. In such things he took the pride of a success- ful craftsman who knows that his work is good. His first scientific papers were written in codperation with others, and treated of the recent mollusks. After going to Al- bany he continued to collect and study the local fauna. These, together with material collected at Warren and near Ann Arbor, or obtained by exchanges, amounting in all to about twenty thou- sand specimens, he gave to the New York State Museum in 1886 and 1887. Beside work on the collections at Albany he rendered, accord- ing to Prof. James Hall, important assistance to that gentleman in the preparation of his great monographs of the different groups of invertebrates from the New York rocks, especially the Mollusks, Polyzoa, and Corals. These works were printed by the State of New York, and in the prefaces ample acknowledgments are made of Beecher’s services. Always skillful as a draftsman, he added to his small salary from the State by making drawings for professional men at Albany, and most of his papers were illustrated by his own hand. His vacations were spent at localities where collections could be made, especially the richly fossiliferous beds of the Helderberg Mountains, near Albany, New York. Of his collections here Professor Jackson remarks :* “Indian Ladder,” in the Helderberg Mountains, was always a favorite and fertile spot for him, dating back to his Albany days. It is one of the most beautiful and picturesque regions in the Helderbergs. He collected there slabs of limestone containing *American Naturalist, vol. xxxvmi, No. 450, p. 411. 60 CHARLES EMERSON BEECHER. fossils which were silicified in the most perfect condition for development by etching with acid. From such materials he ob- tained specimens of surpassing beauty and scientific interest. Beside adult fronds of Bryozoa, Brachiopoda, Crustacea, and other fossils in most perfect preservation, he obtained minute embryos and small species in large numbers in literally wonderful condition of perfection. Young Bilobites half a millimeter in length, young Acidaspis 0.83 millimeter, and Arges 1.15 milli- meters long, both of the latter so perfect that he figured them from both the dorsal and the ventral aspects; young Pleuwro- dictyon consisting of the initial cup alone, and also others with the first lateral buds; young Bryozoa showing initial chambers. © Such material, selected with infinite care and patience, formed the basis of a number of papers by Beecher and others. At this period Beecher published independently a paper on Phyllocarida, a group in which he never lost interest, from ma- terial collected by him at Warren, Pennsylvania; and several papers on the recent Rissoide. His most important work of this period was based on Brachiopoda obtained from the clays of Waldron, Indiana, in which he was associated with John M. Clarke. This paper is one of the first on the development of Paleozoic Brachiopoda, and opened up several new lines of in- vestigation. In 1888 Prof. O. C. Marsh, of New Haven, induced Beecher to accept the position of Assistant in Paleontology at the Peabody Museum of Yale University, though for a time he was also named Consulting Paleontologist to the Museum at Albany, and re- turned there from time to time in connection with the duties of this honorary position. He also pursued his studies at Yale, under Dana, for the degree of Ph. D., which was conferred upon him in 1889, his doctoral thesis treating of the Brachio-spongii- dz, a group of fossil sponges of which the Yale Museum has an unusually fine series. Owing to the illness of Professor Dana, in 1891, Beecher took charge of the classes in Geology during that and the following year, when he was made Instructor in Paleontology, and later Assistant Professor of Paleontology, be- coming in 1897 Professor of Historical Geology and a member of the Governing Board of the Sheffield Scientific School of Yale University. 61 NATIONAL ACADEMY OF SCIENCES. Professor Marsh recognized Beecher’s ability and appreciated his loyalty as assistant in the Museum, which on the Paleon- tological and Geological side Marsh effectively controlled during his lifetime. On Marsh’s death, in 1899, Beecher succeeded him as curator of the geological collections, and was made a member of and secretary to the Board of Trustees of the Museum. He then undertook to arrange, develop, and place on exhibition the Marsh collection of fossil vertebrates. This work was done under his direction, though he personally had much to do with the large mounts of Claosaurus and Brontosaurus, the former of which he has described at length in a paper published by the Connecticut Academy in its Transactions. | In June, 1899, Beecher gave his large and very valuable collec- tion of fossils to the Peabody Museum, as he expressed it, “in grateful recognition of the honors and favors conferred upon me during my connection with the University.” These collections comprised over 100,000 specimens and about five hundred types, which had served as a basis for publications by the States of New York and Pennsylvania and various scientific periodicals. The material was chiefly from the Devonian and Lower Carboniferous of the two States mentioned, and represented the private labor, outside of his official working hours, for some twenty years. “Already interested in studies of the development of organ- isms from his work on the development of Silurian brachiopods, in 1889 Beecher became deeply interested in the late Professor Hyatt’s methods of work—the application of the principles of stages in development, acceleration, parallelism, and dynamic genesis to the unraveling of the genealogical relations of living and fossil animals. Bringing to this work his large and intimate knowledge of species and the structure of fossil types, Beecher entered into this field with characteristic energy and became a leader of the Hyatt school. Beecher’s reputation as an investi- gator will rest chiefly on the rich results he obtained in the erit- ical, painstaking application of those fruitful principles that Professor Hyatt labored so long to establish.”* *R. T. Jackson in American Naturalist for June, 1904. This article and Professor Schuchert’s memoir in the American Journal of Science for the same month have been freely laid under contribution for the purposes of the present memoir. 62 CHARLES EM#RSON BEECHER. “To Beecher we owe the first natural classification of the Brachiopoda and Trilobita based on the law of recapitulation and on chronogenesis. He also gave a very philosophic account as to the origin and significance of spines in plants. and animals. On these works his reputation in days to come will chiefly rest.”* In 1893 there was discovered in the Utica formation near Rome, New York, a band, not over-one-fourth of an inch thick, in which oceur the trilobites Triarthrus and Trinucleus, ex- quisitely preserved as pseudomorphs in iron pyrite, retaining an- tenne and legs and manv of the more delicate parts. This dis- covery, by W. S. Valiant, afforded a hitherto unparalleled oppor- tunity for the study of these animals. ‘'T'wo specimens of Trilo- bites with legs had been previously known; W. D. Mathew had announced the presence of antenne, and Walcott by laborious serial sections had determined the number and approximate form of the legs and gills in a number of species. Now, however, a vastly better opportunity for precise observation of the details of the structure of these animals was presented. Beecher took out several tons of the shale and, aided by his remarkable manual dexterity, mechanical skill, and untiring patience, worked out the structure of antenne, legs, and other ventral appendages with a minuteness which had previously been impossible. Since 1893 he published fifteen papers on the Trilobites, including in 1897 a Classification based on these studies, in which the group was divided into three orders, founded chiefly on the development of the free cheeks. At the time of his death he was at work on an extensive monograph of Trilobite structure. He regarded these animals as forming a subclass equal in rank to the Ento- mostraca and Malacostraca, stating that in nearly every partic- ular “the Trilobite is very primitive and closely agrees with the theoretical crustacean ancestor. Its affinities are with both the other subclasses, especially their lower orders, but its position is not intermediate.” More than five hundred specimens of T'ri- nucleus and Triarthrus were prepared by him, and Schuchert ob- serves that few can appreciate the remarkable talent displayed in clearing the adhering black shale from these smal] specimens, and that it will be a long time before his equal in this delicate work is likely to appear. * Charles Schuchert, op. cit. NATIONAL ACADEMY OF SCIENCES. Beside his works on the Corals, Brachiopods, and Trilobites above referred to, he became in 1892 deeply interested in the sig- nificance of spines, accumulating material till 1898, when he pub- lished his memoir entitled “The origin and significance of spines,” the longest of .his papers and the one, according to Schuchert, which he regarded as his best and most philosophic work. Fortunately for students of Paleontology, most of Beecher’s more important papers were reissued in one volume in the Yale Bicentennial series, entitled “Studies'in Evolution.” He himself regarded the reprinting of already published papers as a kind of extravagance; but those interested in philosophical zoology will feel grateful for the combination of so many important con- tributions to it in the compass of one volume. His views on the classification of the Brachiopoda and Trilobita are incorporated in the translation by Eastman of Zittel’s Grundztige der Paleon- tologie. In his bachelor days at New Haven, Beecher, with Pirsson, Penfield, and Wells, roomed in “The Attic,” the top story of the Sheffield Scientific School, which was comfortably fitted up in true Bohemian style; and Jackson recalls as one of the pleasant-— est recollections of a visit to New Haven the memory of calls at “The Attic,” where, after working hours, delightful intercourse, social and scientific, was held, often far into the night. After moving to New Haven, Beecher made his single journey abroad in company with the late Dr. George Baur, visiting many Euro- pean museums. | September 12, 1894, Professor Beecher married Miss Mary Salome Galligan, of Warren, Pennsylvania, who, with two daugh- ters, his mother, and one brother, survives him. Always delicate, of medium height, dark hair and eyes, and apparently good physique, Professor Beecher had the aspect of a man whose years might be long in the land, and of late had seemed to enjoy excellent health, but he died suddenly, from an affection of the heart, February 14, 1904, with no warning to soften the blow to those who loved him. His remains lie in Grove Street Cemetery, New Haven, in the shadow of the Shef- field Scientific School. The director of the school has said of him: “Quiet and unas- 64. CHARLES EMERSON BEECHER. = sunmling, he never sought adulation, but when there was earnest work to be done, requiring skill, patience, and good judgment, he would labor quietly and industriously, bringing to bear upon the problem such a meastire of common sense and of thoughtful- ness that confidence in and respect’ for his conclusions were in- evitable. * * * No matter how trivial the duty, it was al- ways done at the appointed time, and thoroughly done. * * * As a friend he was loyal and trustworthy, and his memory will always be cherished by his associates in the Sheffield Scientific School.” One of his pupils has testified to the inspiration given by him to his students, and how his patience, perseverance, and in- genuity served as an incentive to his associates, who were drawn closely to him by his enthusiasm and entire lack of egotism. There is no doubt that in the death of Professor Beecher not only has Yale sustained a serious icss and Paleontology a severe blow, but the ranks of those capable of bringing to the study of fossils keen insight and a philosophical spirit of inquiry, guided by principles whose value can hardly be exaggerated, are dimin- ished by one whom science could ill afford to lose and to whom, humanly speaking, there should have remained many vears of industrious and fruitful research.
