Douglas Noel Adams was an English author, scriptwriter, essayist, humorist, satirist 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 and generated 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 and The Long Dark Tea-Time of the Soul , and co-wrote The Meaning of Liff , The Deeper Meaning of Liff , Last Chance to See , and three stories for the television series Doctor Who; he also served as script editor for the show's seventeenth season in 1979. A posthumous collection of his works, including an unfinished novel, was published as The Salmon of Doubt in 2002.
Adams was known as an advocate for environmentalism and conservation, as a lover of fast cars, cameras, technological innovation and the Apple Macintosh, and as a "devout atheist".
