Deep Thought was a computer designed to play chess. Deep Thought was initially developed at Carnegie Mellon University and later at IBM. It was second in the line of chess computers developed by Feng-hsiung Hsu, starting with ChipTest and culminating in Deep Blue. In addition to Hsu, the Deep Thought team included Thomas Anantharaman, Mike Browne, Murray Campbell and Andreas Nowatzyk. Deep Thought was easily defeated in both games of a two-game match with Garry Kasparov in 1989 as well as in a correspondence match with Michael Valvo. It was named after Deep Thought, a fictional computer in Douglas Adams' series, The Hitchhiker's Guide to the Galaxy.
