Douglas Adams was an English writer, humorist, and dramatist. Adams is best known as the author of The Hitchhiker’s Guide to the Galaxy, which originated in 1978 as a BBC radio comedy before developing into a "trilogy" of five books that sold more than 15 million copies in his lifetime, a television series, several stage plays, comics, a computer game, and in 2005 a feature film. Adams’s contribution to UK radio is commemorated in The Radio Academy’s Hall of Fame.
Adams also wrote Dirk Gently’s Holistic Detective Agency (1987) and The Long Dark Tea-Time of the Soul (1988), and co-wrote The Meaning of Liff (1983), The Deeper Meaning of Liff (1990), Last Chance to See (1990), and three stories for the television series Doctor Who. A posthumous collection of his work, including an unfinished novel, was published as The Salmon of Doubt in 2002.
