                  and artificial intelligence are legendary. He
                  invented Lisp, made substantial contributions to
                  early work in timesharing and the theory of
                  computation, and was one of the founders of
                  artificial intelligence and knowledge
                  representation. This article, written in honor of
                  McCarthy’s 80th birthday, presents a brief
                  biography, an overview of the major themes of his
                  research, and a discussion of several of his major
                  papers. },
