My father was out there and had the privilege of seeing Castle Bravo in 1954. I don’t know for sure if he saw Mike. Bravo was much bigger than expected. Oops. My father died of cancer, but it was many years later.

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.)

My Dad was there. How do I post a picture?

The fission-fusion method that was proved to work in the "Mike" test remains fundamental to H bomb design, with the hydrogen put into a stable compound form to save enough weight and space to make such bombs practical and deliverable as weapons. In addition, "Mike" spurred the career of its designer and advocate, conservative Hungarian emigre Edward Teller, against the leftist Robert Oppenheimer, the head of the Manhattan Project, who had opposed the development of the H Bomb.
