Too modern for me, my classic semiconductors are Germanium :-)
Perhaps they allow the relay/valve/germanium generation (which does
NOT include me by the way) to contribute too.

Michael Riordan (Crystal Fire) may be more appropriate for your interests.
The people mentioned seem appropriate for something called "Silicon Genesis"
though it probably should have said pioneers "in" the semiconductor industry
and not "of". There clearly was a semiconductor industry elsewhere before
Shockley and Fairchild.
People in "Silicon Valley" have an unfortunate habit of discounting technology
that was was created before there was a "Silicon Valley".

goes back a bit farther.
There is an active group at CHM working on documenting semiconductor history.

The same is true for networking people and what was around before ARPAnet.
There is an active group at CHM working on documenting
semiconductor
history.
Is there any liason between this CHM group and the Tube Collector
Association? We in the TCA have been branching out into early
semiconductors for a few years now (but generally not ICs).

If you can find it, take a look at an article that just came out in
the spring 2009 issue of Invention & Technology called "Long Live the
Vacuum Tube!" by Mara Vatz. It has amazing "facts" in it like:
"The basic structure of a vacuum tube is simple: two pieces of metal
separated by nothingness, a vacuum. One piece, the cathode, is heated,
which compels more electrons to leave its confines, or "evaporate", than
would happen at room temperature. The other piece, the anode, is not
heated. The temperature disparity between the two causes electrons
evaporating from the heated anode to travel across the vacuum to the
unheated cathode, but not the other way around."
and..
"Transistors perform essentially the same function, only on a far
smaller scale. But while vacuum tubes have nothing between their two
pieces of metal for an electron to latch onto, transistors are made
of nonconducting ceramic material, which isn't as clean as a vacuum".
This is from a book published by >> MIT PRESS <<
called "Falling for Science: Objects in Mind"
I was hoping this was an April issue, but it appears it is a real article.

It would not be a bad idea to get the two groups talking. There are
some SERIOUS researchers in the TCA, and quite a treasure trove of
documentation.

Eeewww...
So, when they compared tubes and transistors used in computers, did
they find the biggest tube they could get their hands on for the photo
shoot?

Well, there we have it! - a concise technical explanation of why tube
audio amps sound better then transistor amps.
