"was carried out personally by Richard Feynman"
Feynman's own essay on the subject is quite clear that he was tipped off by someone else and merely provided the media presence necessary to put the evidence into the public domain. I'll stick my neck out here and say he'd be a little upset at the way popular culture has deified him. He enjoyed the limelight, but he'd have hated the thought that personalities might be bigger than either evidence or a decent bit of research by a competent nobody.
