Henry: I saw your post about isotopes. I knew the guy who discovered kinetic isotope effects.
Me: You did?
Henry: Yes. Jacob Bigeleisen. We roomed together during graduate school at Berkeley. He wasn't famous then of course. That came later. He went to Columbia afterwards. That was early in the war, when the Manhattan Project was still in Manhattan.
Me: Wow! Tell me more about it!
