Back in the late 80’s when I was at IBM Research, there was an IBM Fellow (Richard Garwin, a physicist) down the hall from me whom I talked to once or twice. I found out much later that he had been the person tasked by Teller to do the engineering design for the “Mike” device.
(In another “found out later” case, it turned out that the person down the hall from my first office there in 1970, Robert Dennard, had been the inventor, in 1966, of the first practical DRAM.)
I enjoy reading the “who would ever think?” type stories.
Thanx!
