PREFACE 



With genuine pleasure and pride this "Encyclopedia of Microscopy" is presented as the 

 fourth in a series of Reinhold contemporary^ integrated compilations of rapidly developing 

 areas of science, following the "Encyclopedia of Chemistry" (1957), the "Encyclopedia of 

 Chemistry Supplement" (1958), and the "Enc^'^clopedia of Spectroscopy" (December, 1960). 

 Actually, "Spectroscopy" and "^Microscopy" were planned, projected, assembled and edited 

 concurrently as twin volumes, but of necessity there was an interval of a few months in 

 publication of the two, or a slightly delaj'ed birth, as it were, of the second twin. 



These two great instrumental techniques, valuable in so many disciplines, are so inti- 

 mately related and interwoven that the simultaneous development of encyclopedias was the 

 most logical procedure. Even though microscopy as a science is about three centuries old 

 and spectroscopy only one, the common background and origins are well exemplified in the 

 respective historical articles by Professor E. K. Weise. It may not be surprising, then, that 

 one Preface was written originally for both Encyclopedias. This has appeared already in 

 "Spectroscopy," and it is hoped that users of this volume will have the opportunity to read 

 this more extended introduction to the pair of volumes, as well as to browse in a kindred 

 science. 



The "Encyclopedia of Microscopy" is the fruit of the joint efforts of a trulj' international 

 team of dedicated microscopists — English, Scotch, Canadian, South African, French, Ger- 

 man, Swiss, Dutch, Swedish, Japanese and American — and it is this fact that gives such 

 unique flavor, value and good will to the able and devoted coverage of a science which is as 

 wide and boundless as the world itself. 



This Encyclopedia, of course, is a mosaic of 26 kinds of microscopj^ alphabetically arranged, 

 and in most cases wdth numerous alphabetical subtopics under each. The numerous illus- 

 trations in this picture book — diagrams of all kinds, photographs of microscopes and related 

 instruments, and the micrographs made with them — speak eloquently' for themselves as 

 superb art as well as science, heretofore unpublished in most cases. Carefully chosen lists 

 of general and cross references, it is hoped, will add greatly to the value and usefulness of 

 this volume to inquisitive students and laymen seeking information and illumination in this 

 area which extends the powers of men's vision a millionfold or more, and to the experts who 

 continue to build an ever-new science. 



The Editor is indebted personally to all the eminent scientists throughout the world who 

 have contributed vitally important advice and encouragement, as well as one or more arti- 

 cles based on experience and devotion in a specialized field. The entire list of authors pre- 

 sented in the front pages is indeed a Roll of Honor. Special mention is due to colleagues at 

 the University of Illinois — Professors E. K. Weise of the Department of Mining and Metal- 

 lurgical Engineering, and R. Borasky, Director of the Electron Microscope Laboratory; 

 and to the two loyal and able secretaries serving consecutively, Mrs. Ruth Tuite (1958-9) 

 and Mrs. Claretta ]\Ietzger (1959-60), with whose help the entire task of planning, organiz- 

 ing and editing has somehow been accomplished. 



The patience, enduring faith, guidance and technical aid by the publishing staff, especi- 

 ally G. G. Hawley, Executive Editor, and Alberta Gordon, were indispensable factors in 

 bringing both Encyclopedias to material fruition, and in looking ahead to new worlds of
