Will Crowther

William Crowther was a programmer at Bolt, Beranek and Newman (the company that built ARPANET) who created Colossal Cave Adventure in 1976 - the first text adventure game. Drawing on his experiences exploring Mammoth Cave in Kentucky and his love of Dungeons & Dragons, Crowther created something entirely new: an interactive fiction that let players explore a virtual world through text commands.
