as I noted in another post, there can’t be many of those guys still around
Feynmann was at Alamagordo around age 24, and was the young genius of the bunch, and he’s been dead for years already; the last one of that generation to go was probably Ed Teller, who was ten years older than Feynmann, but died in 2003. Teller is sometimes called controversial, but that’s only because he was anti-communist. He’s easily the most interesting of all of them, even though Feynmann is the most fun.
