Douglas Noel Adams (11 March 1952 – 11 May 2001) 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.
