I like Richard Feynman quite a bit, if not for anything else then the Feynman integral. A couple of great bios on him is Genius (Pantheon) and The Beat of a Different Drum (Oxford). Gleick's 'Genius' is easier to read then Mehra's 'Drum,' which goes into the physics and math in more detail.
I recall the Gleick book to be a very good read.
No love for Niels?
Bohr was obviously a great physicist and great interpreter of abstract results, but in my view not quite a revolutionary in the field. He definitely makes the short list (most Nobel winners do, I suppose), but not, IMO, the REAL short list.
You say you want a revolution? (Ary?)
