Sir Arthur Charles Clarke (16 December 1917 – 19 March 2008) was a British science fiction 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.

Clarke was born in Minehead, Somerset, England. As a boy, he grew up on a farm enjoying stargazing and reading old American science fiction pulp magazines. During the Second World War he served in the Royal Air Force as a radar specialist and was involved in the early warning radar defence system which contributed to the RAF's success during the Battle of Britain. Clarke spent most of his wartime service working on Ground Controlled Approach (GCA) radar. After the war he earned a first-class degree in mathematics and physics at King's College London.

In the postwar years, Clarke became the Chairman of the British Interplanetary Society from 1946–1947 and again from 1951–1953. Although he was not the originator of the concept of geostationary satellites, one of his most important contributions may be his idea that they would be ideal telecommunications relays. The concept was published in Wireless World in October 1945. Clarke also wrote a number of non-fiction books describing the technical details and societal implications of rocketry and space flight. The most notable of these may be The Exploration of Space (1951) and The Promise of Space (1968). In recognition of these contributions the geostationary orbit 36,000 kilometres above the equator is officially recognised by the International Astronomical Union as a Clarke Orbit.

His first professional novel appeared in Astounding Science Fiction in 1946, Along with his writing Clarke briefly worked as Assistant Editor of Science Abstracts (1949) before devoting himself to writing full-time from 1951 onward.

In 1948 he wrote "The Sentinel" for a BBC competition. Though the story was rejected, it changed the course of Clarke's career. Not only was it the basis for 2001: A Space Odyssey, but "The Sentinel" also introduced a more cosmic element to Clarke's work. Many of Clarke's later works feature a technologically advanced but still-prejudiced mankind being confronted by a superior alien intelligence. In the cases of The City and the Stars (and its original version, Against the Fall of Night), Childhood's End, and the 2001 series, this encounter produces a conceptual breakthrough that accelerates humanity into the next stage of its evolution.

Clarke lived in Sri Lanka from 1956 until his death in 2008, He was an avid scuba diver and a member of the Underwater Explorers Club. In 1956, while scuba diving, Clarke uncovered ruined masonry, architecture and idol images of the sunken original Koneswaram temple — including carved columns with flower insignias, and stones in the form of elephant heads — spread on the shallow surrounding seabed

His many predictions culminated in 1958 when he began a series of magazine essays that eventually became Profiles of the Future, published in book form in 1962. A timetable up to the year 2100 describes inventions and ideas including such things as a "global library".
