No question about it. Those years were certainly memorable for me.

By the way, I forgot to mention another noteworthy person whom I met: Stanislaus Ulum. He was a mathematician at Los Alamos. Teller got as far as he presumably could in developing the theory necessary for production of the hydrogen bomb, then ran into a problem that he could not handle: How to eliminate the need for a huge refrigeration system as part of the bomb to enable it to work, too heavy to carry in an airplane. Ulum worked out the theory that finally enabled Teller to make the hydrogen bomb so that it would achieve a fusion reaction.

I took differential equations under Ulum during my senior year at the University of Wisconsin in the 1942-1943 school year. He was a Hungarian and I remember him for his weird accent and his sort of a wild-eyed look, but mostly I rember him as being a remarkably good teacher.
