Douglas Noël Adams was an English author, comic radio dramatist, and musician. He is best known as the author of the
Hitchhiker's Guide to the Galaxy
series. Hitchhiker's began on radio, and developed into a "trilogy" of five books (which sold more than fifteen million copies during his lifetime) as well as a television series, a comic book series, a computer game, and a feature film that was completed after Adams' death. The series has also been adapted for live theatre using various scripts; the earliest such productions used material newly written by Adams. He was known to some fans as Bop Ad (after his illegible signature), or by his initials "DNA".
In addition to The Hitchhiker's Guide to the Galaxy
, Douglas Adams wrote or co-wrote three stories of the science fiction television series Doctor Who and served as Script Editor during the seventeenth season. His other written works include the Dirk Gently novels, and he co-wrote two Liff books and Last Chance to See
, itself based on a radio series. Adams also originated the idea for the computer game Starship Titanic
, which was produced by a company that Adams co-founded, and adapted into a novel by Terry Jones. A posthumous collection of essays and other material, including an incomplete novel, was published as
The Salmon of Doubt
His fans and friends also knew Adams as an environmental activist and a lover of fast cars, cameras, the Macintosh computer, and other "techno gizmos".
Toward the end of his life he was a sought-after lecturer on topics including technology and the environment.
