Murray Campbell is a research staff member at the IBM T.J. Watson Research Center in Yorktown Heights, New York. Earlier at IBM, Campbell was a key member of the team that designed and built the Deep Blue supercomputer system that defeated reigning World Chess Champion Garry Kasparov in a six-game match in 1997.
Campbell was a strong expert-level player while still in high school and brought this knowledge to the development of Deep Blue’s evaluation function--the component of Deep Blue that assesses the value of the current position in a game. He also worked closely with the team's chess consultant, international grandmaster Joel Benjamin, in developing Deep Blue's opening book.
Campbell is now manager of the Deep Computing in Commerce department at IBM.
