Richard Greenblatt was primary author of The Greenblatt Chess Program in 1966 and 1967, and along with [|Tom Knight], main designer of the [|MIT Lisp machine]. In 1978 Mac Hack got adapted to the Chess-orientated Processing System CHEOPS, one of the first dedicated hardware approaches in computer chess.

In 1979, Greenblatt founded [|Lisp Machines, Inc.] to build and sell [|Lisp machines], competing with [|Symbolics], a company founded by his former [|MIT AI Lab] fellows around [|Russell Noftsker], [|Tom Knight] and Jack Holloway. Lisp Machines, Inc. went bankrupt in 1987. || toc =Photos= =Selected Publication=
