computer pioneer
Slug
Steve Russell is a programmer and computer scientist most famous for leading team of programmers that created the first computer video game, Spacewar, while studying at the Massachusetts Institute of Technology (MIT). The game was conceived in 1961 and released in 1962. It took Steve and his team about 200 man-hours to write the first version, which was developed on a DEC (Digital Equipment Corporation) PDP-1 minicomputer.
Steve also wrote the first two implementations of Lisp for the IBM 704 after having a class about the (until then) theoretical language. He invented the continuation to solve a problem for one of the users of his Lisp implementation.
