Sandy Douglas, English computer scientist and academic, designed OXO (died 2010)

Alexander Shafto "Sandy" Douglas CBE was a British professor of computer science, credited with creating the first graphical computer game, OXO, a version of noughts and crosses, in 1952 on the EDSAC computer at University of Cambridge.

OXO is a video game developed by A S Douglas in 1952 which simulates a game of noughts and crosses (tic-tac-toe). It was one of the first games developed in the early history of video games. Douglas programmed the game as part of a thesis on human-computer interaction at the University of Cambridge.
