Chris Crawford earned a Master of Science degree in Physics from the University of Missouri in 1975. After teaching physics for several years, he joined Atari as a game designer in 1979. There he created a number of games: Energy Czar, an educational simulation about the energy crisis, Scram, a nuclear power plant simulation, Eastern Front (1941), a wargame, Gossip, a social interaction game, and Excalibur, an Arthurian game.Following the collapse of Atari in 1984, Crawford took up the Macintosh.

He is now commercializing his technology at his company website at storytron.com.Crawford has written five published books: The Art of Computer Game Design, now recognized as a classic in the field, in 1982; Balance of Power (the book) in 1986; The Art of Interactive Design in 2002; Chris Crawford on Game Design in 2003; and Chris Crawford on Interactive Storytelling in 2004.He created the first periodical on game design, the Journal of Computer Game Design, in 1987. He founded and served as Chairman of the Computer Game Developers' Conference, now known as the Game Developers' Conference.Crawford has given hundreds of lectures at conferences and universities around the world, and published dozens of magazine articles and academic papers.Crawford served as computer system designer and observer for the 1999 and 2002 NASA Leonid MAC airborne missions; he also has done some analysis of the resulting data. He lives in southern Oregon with his wife, 3 dogs, 7 cats, 2 ducks, and 3 burros.His current work is in interactive storytelling.
