EARLY TRANSISTOR HISTORY AT RCA

Richard Endres

 

Biographic Note

 

Dick Endres was instrumental in early transistor applications work at RCA, making substantial contributions in transistorized digital computer circuits.  His early work is best documented in the text, “Transistor Electronics” – he co-authored this highly regarded book, which was first published in 1955 by Prentice Hall.  While at RCA, Dick was named co-inventor of a very early patent (filed in 1949) for point contact transistor oscillator circuit applications – in addition, he was actively involved in the first RCA digital computer programs, including the Solectron memory tube and the BIZMAC computer.  He left RCA in 1955, and went on to establish several companies involved in  electronics and consulting, including RESE Engineering, Computest and Venture Resources.

Oral History – Dick Endres

 

My first assignments at RCA were at the David Sarnoff Research Center in Princeton, and then in the Advanced Developmet Department of  Industrial Product Division in Camden.  I knew Slade, Giacoletto, Lohman, et. al. but my activities didn't intersect much with theirs.  Also, they were fairly experienced engineers while I was just fresh out of Purdue on the lowest rung of the engineering ladder.

 

I started at RCA in March of '48, and was fortunate to be assigned to transistor circuit development in September.  (I seem to remember that BTL revealed the transistor in Physical Review in July, not June, but could be wrong.)

 

Those early years activities at RCA were digital computer related, so my transistor work was mostly on non-linear circuits.  In Advanced Development, I was associated with Arthur Lo in some of that work.  As he may have told you, Zawles, Waldhauer (deceased) and Cheng, who collaborated with us on the book, were in  the Home Instruments Division.

 

Transistor Electronics was published by Prentice Hall in the U.S., by MacMillan in the U.K., Spanish language in (I believe) Argentina, and finally translated into Japanese by the head of the EE Dept. at Tokyo University.  As I mentioned, we received no royalties from the Russian translation!
