An interesting and surprising fact about Feynman's books is that he never _wrote_ any of them, as such; he famously disliked writing. QED is essentially a transcript of a lecture (although I don't know how much polishing and editing was done by Feynman himself; probably some). Same with his collection of physics lectures. His most popular book, "Surely You're Joking, Mr. Feynman", was transcribed from a series of interviews, pretty much verbatim.
