Sir Arthur Charles Clarke (16 December 1917 – 19 March 2008) was a British author, inventor and futurist, famous for his short stories and novels, among them 2001: A Space Odyssey (1968), and as a host and commentator in the British television series Mysterious World. For many years, Robert A. Heinlein, Isaac Asimov, and Clarke were known as the "Big Three" of science fiction.
