I think above all else Feynman was charismatic & engaging. Absolutely brilliant. He was also known to be extremely difficult in his credit-seeking (earned or not). Certainly wasn't a fraud, but I think letters like Oppenheimer's probably hurt the candidates more than are helpful (whether or not read by candidate). If read, it can't help with ego/bullying.
