Clarke was born in Minehead, Somerset, England. As a boy he enjoyed stargazing and reading old American science fiction pulp magazines. After secondary school and studying at Huish's Grammar School, Taunton, he was unable to afford a university education and got a job as an auditor in the pensions section of the Board of Education.
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 time working on Ground Controlled Approach (GCA) radar as documented in the semi-autobiographical Glide Path, his only non-SF novel. Although GCA did not see much practical use in the war, after several years of development it was vital to the Berlin Airlift of 1948–1949. He initially served in the ranks, and was a Corporal when he was commissioned as a Pilot Officer (Technical Branch) on 27 May 1943. He was promoted Flying Officer on 27 November 1943 He was demobilised with the rank of Flight Lieutenant. After the war he earned a first-class degree in mathematics and physics at King's College London. ...... Read more:http://en.wikipedia.org/wiki/Arthur_C._Clarke
