Do you know the story of the CK722?
In the 1950s, Raytheon was making tiny transistors for hearing aids to
replace the pre-WW II subminiature tubes.
Aside: Those tubes, developed by Norm Krim, were ruggedized and used in
the WW II Proximity Fuzes, one of THE big inventions of WW II.
Neat story. Strange that his name (according to google books)
doesn't appear in "The Deadly Fuze". It's still a good book, BTW.
