Greenblatt, Richard D.
Richard D. Greenblatt, born in 1945, is a computer programmer. In late 1966, as an MIT undergraduate, he began to develop a computer chess program of his own. He had been challenged by Hubert Dreyfus, who criticized the usefulness of Artificial Intelligence and was an anti-computer opponent, that computers would not be able to play chess or be good enough to beat a ten-year-old. An early version was up and running by the end of 1966. MIT was using a computer time-sharing grand called Project MAC (Multiple Access Computing). Greenblatt’s program ran on a PDP 6. He called his creation MAC HACK 6 and programmed it in assembly language. His program was able to beat Greenblatt’s critic, Hubert Dreyfus, which checkmated him in the middle of the board. In 1967, It was the first computer chess program to play in chess tournaments with human players. Greenblatt was offered an MIT degree if he would write a thesis about his chess program, but he never got around to writing a thesis. Greenblatt was the main designer of the MIT Lisp machine. In 1980, Greenblatt founded LMI (Lisp Machines, Inc) to market Lisp machines.
