The FBI Files of Richard Feynman

Earlier this year Michael Morisy, one of the founders of the group MuckRock which specializes in Freedom of Information Act requests, obtained files from the FBI  for Richard Feynman. Given the brevity of the response (365 pages) and the importance of Feynman to so many substantial federal projects, it seems to me this is likely incomplete, but that is but a guess.

Regardless, some apparently thought Feynman was a communist and a spy. One tipster (whose name the FBI redacted in its response) stated:

I do not know—but I believe that Richard Feynman is either a Communist or very strongly pro-Communist—and as such is a very definite security risk. This man is, in my opinion, an extremely complex and dangerous person, and a very dangerous person to have in a position of public trust, particularly a position that so vitally affects the safety and welfare of this nation-both present and future as that of Science Advisor [sic] for President Eisenhower.
