Was Paul Dirac so strange?

I don't think Paul Dirac was strange. In a way, he was having the normal life of a scientist, keeping himself on purpose or not away of his (very troubled) times. Lacking the glamour, extravaganza and mistery of another personality of 20st century physics, Oppenheimer (whose biography I am reading right now) Dirac was rather an autist - the dialogues between he and his wife are offering various examples in this sense. His political statements, on the side of communism, but lacking any direct involvement against the Nazis, including by sending a wake-up call to his colleagues and friends, were weak. His religious option was an understatement. I was expecting to find more scientifical background of his works. Instead, the book is a lengthy focus on various episodes of his life - with psychoanalitical interpretations. Maybe it is hard to write about scientists' lives.
