Herbert Simon won both the Turing Award and the Nobel Prize

Herbert A. Simon (1916-2001) is one of very few people honored at the top level of two distinct fields. He shared the 1975 ACM Turing Award with Allen Newell for contributions to artificial intelligence and cognitive psychology, and in 1978 he won the Nobel Memorial Prize in Economic Sciences “for his pioneering research into the decision-making process within economic organizations,” as stated in the official Nobel Prize citation.
