Also during the time from 1952
to 1955, I took the exam and qualified for the Advanced Engineering Program
– we had a few hours of class work and 20 hours of homework to do every
week (included advanced mathematics, heat transfer, and other topics not
normally taught to an electrical engineer). It was considered an honor to be accepted into this program –
Brainard Fancher, who was the general manager of the Semiconductor Products
Department was also a graduate of the program. Anyway, after this program, in the late spring of 1955, Jim
Sweeney was the manager of marketing up at “Semiconductor” and he was
looking to setup an applications engineering group. So I went to interview and took his job
offer and we moved to Syracuse in the summer of 1955.
Sweeney suggested to me that it
would be a good idea to come up with a manual for transistors similar to
the RCA Tube Manual, which he was used to.
So I wrote the first GE Transistor Manual (must have been in 1956 or
1957) , and, if you notice, there are quite a few diagrams and artwork –
this was done by the Advertising Dept under Sweeney. The Manual was a real success, and so
every year or so we would update the manual with a new edition. Various engineers would design and test
the circuits we used in these manuals – Erich Gottlieb worked on the radio
circuits, Peter Sylvan did the unijunction transistors and Dwight Jones and
I did the audio projects. We always
tried these circuits with multiple transistors to make sure they would work
ok. The first manual was introduced
at an Electronics Convention in New York, and Sweeney was selling them for
50 cents each.

The fifth edition came out in
1960 and it has my name listed as the Manager of Applications on the first
page, along with all the other applications engineers. The seventh edition was the last and
largest – it was edited by J.F. Clearly, as I had moved over to manage
engineering for the new signal diode project.
GE established a diode project,
to develop a diffused planar diode that would perform better than the point
contact diode – we were first in the industry with this type of
product. We also designed it to be
temperature resistant and this was needed for programs like the Minuteman
missile. The diode was very
successful and we continued to be the applications/manufacturing group for any new, experimental products
developed at the Research Labs by folks like Nick Holonyak, such as tunnel diodes, high frequency oscillator
transistors, light emitting diodes, and SCR’s. I remember one conference, early on, where several papers had
been given on the promising Tunnel Diode technology and about how these
devices weren’t yet available commercially. Well, I was able to announce immediate delivery from GE and
this caused quite a sensation at the conference. In 1961, we came out with the first and only edition of the
GE Tunnel Diode manual. Although
tunnel diodes were easy to make and seemed to have excellent performance
(negative resistance, high frequency switching) they never really caught
on. We never produced a 2nd
edition of the manual.
