Date of birth: December 16, 1917 Place of birth: Minehead, Somerset, England Arthur C. Clarke moved to London in 1936, there he joined the British Interplanetary Society (which he presided from 1946 - 1947 and from 1950 - 1953). There he started to experiment with astronomic material. During World War II, Clarke served as a RAF officer in charge of the first radar "talk-down" equipment during its experimental trials. His only non science fiction work "Glide Path" is based on his experiences in WWII. In 1945 he published the technical paper "Extra - Terrestrial Relays", which layed down the principles of satellite communications on geostationary orbits. These principles gave him numerous honors, like the Marconi International Fellowship in 1982, a Fellowship at King's College (London), a gold medal from the Franklin Institute, among others. Today, the geostationary orbit at 42,000 Km. is named the Clarke Orbit by the International Astronomical Union.
