PREFACE 


“L’avenir de &lectricite, c’est dans le vi 
future of electricity lies in the vacuum.) This remark, 
made before the Academie a generation ago by a famous French 
physicist, has proved to be prophetic. For the world has 
witnessed amazing developments in that branch of electricity 
which is based upon the employment of a vacuum: ELECTRONICS. 
Yet in spite of these great developments (or possibly be- 
cause of them), and in spite of an increasingly urgent need 
for foreign-language dictionaries, students of electronics 
and allied problems have been forced to proceed without a 
lexicographical tool which brings together the terminologies 
of the two languages most vital to their work, German and 
English. 


The authors believe that this volume will be wel- 
comed by all electronics engineers and all physicists, not- 
withstanding certain limitations in size and scope which 
have been imposed by the war. It contains nearly 21,000 en- 
tries, representing most of the terminology current in 1939 
and an appreciable number of terms introduced during the war 
years. 


Owing to a lack of earlier German-English dictionar- 
les in the general field of physics, the task of compilation 
has proved unusually difficult. The only outstanding refer- 
ence books hitherto available for consultation have been 
Sattelberg’s Worterbuch der elektrischen Nachrichtentechnik 
(1926) covering the signal art in general, and Austin M. 
Patterson’s famous German-English Dictionary for Chemists 
(1935). The bulk of the material in the present volume 
has been drawn from magazines, scientific journals, books, 


and patent literature. The definitions gleaned from other 
books have in most instances been amplified and re-worded. 


A somewhat unorthodox policy has been followed by 
frequently adding explanatory annotations to the English- 


language expressions. This has been done in order to supply 
related terminology for the benefit of the reader who may be 
unfamiliar with a given subject. Ample cross-references 


have been inserted throughout. And for those who desire 
fuller information, source and reference books--including a 
number of outstanding works of British origin--have been 
listed in a bibliography. The authors recommend purchase of 
some of the items included in this list, particularly the 
Electronics Dictionary by Nelson M. Cooke and John Markus. 


Indeed, the authors are deeply indebted to these authors and 
their book for much- valuable information. 


We also wish to express our gratitude to all those 
who have aided us in one way or another, especially to E. R. 
Weinmann, Arthur Worischeck, Walter Brunberg and Dr. G. Orn- 
sen who assisted in the proofreading. We shall be equally 
grateful to those who bring to our attention such errors, 
imperfections, and omissions as are inevitable in the first 
printing of a work which is a pioneer in its field. A re- 
vised and amplified edition is being planned for a future 
date, and correspondence with the authors is solicited from 
those wishing to co-operate in the compilation of a revised 
text.
