Murray Gell-Mann said exactly this. He basically got tired of working with him because everything about his personality was to generate stories and mythologies about himself.
To me, this whole idea shows what a fool the average man is.
As if we all know so much about Richard Feynman compared to Murray Gell-Mann because of what a great scientist Richard Feynman was. When OBVIOUSLY, the reason is because of the degree Feynman self promoted himself compared to
other scientists.
