Benacerraf won the Nobel Prize in Physiology or Medicine in 1979 for his "discovery of the major histocompatibility complex genes which encode cell surface protein molecules important for the immune system's distinction between self and non-self". He shared the prize with Jean Dausset and George Davis Snell.
