It’s been easily 15 years since I read Genius: The Life and Science of Richard Feynman by by James Gleick, and probably 25 or so since I read Feynman’s own books of stories about himself. I remember lots of stories about flirtation, and very probably promiscuity, but I don’t recall sexual predation. That’s not to say it didn’t happen. I haven’t read everything there is about Feynman’s life, and I don’t remember all that I actually have read. But I do not remember predation.
