Documenting Over 30 Years of

 Major Contributions by RCA to Transistor Development


The transistor was invented by John Bardeen, Walter Brattain and William Shockley at Bell Labs in December 1947.  Several major U.S. companies responded to this initial work with large scale research and manufacturing programs which transformed the early “lab curiosity” aspects of the transistor into a mature, ever-evolving technology, responsible for billions of dollars in commerce and providing the technological basis for the modern electronics and computer industries.  RCA was an early and substantial contributor to the development of the transistor.  This publication documents many of these major RCA accomplishments.  Interviews and correspondences with engineers and scientists who were involved form the basis for this material.  You’ll also find photographs of prototype and early production units, as well as a comprehensive coverage of early RCA transistor literature.


This photo shows one of the earliest RCA commercial transistors, a 2N32 point contact germanium unit from 1953 – there is a similar junction unit shown in the photo in the upper right, which has been taken from a 1953 RCA publication extolling the virtues and future of this new technology.
