John McCarthy (September 4, 1927 – October 24, 2011) was an American computer scientist and cognitive scientist. He was one of the founders of the discipline of artificial intelligence, and part of just a small group of artificial intelligence researchers in the 1950s and 1960s. He co-authored the proposal for the Dartmouth workshop which coined the term "artificial intelligence" (AI), led the development of the symbolic programming language family Lisp and had a large influence in the language ALGOL, popularized time-sharing, and created garbage collection.
