I was reading Genius: The Life and Science of Richard Feynman and came across this section:
Image transcribed: "One of Feynman’s fraternity brothers was surprised to see him return home while the examination was still going on. Feynman learned later that the scorers had been astounded by the gap between his result and the next four."
I got this screenshot from https://books.google.com/books?id=IWQ_y90P2uIC&q=putna#v=snippet&q=putnam&f=false
Is this true? From what I can tell, he was simply one of the 5 top scorers in the 1939 Putnam.
It seems that other resources say the same thing, but I can't find any primary evidence.
