Patrick Andrew Clayton DSO MBE (16 April 1896 – 17 March 1962) was a British surveyor and soldier. He was the basis for the character of Peter Madox in The English Patient.
Career
Clayton was born in Croydon, London, in April 1896 and, after serving as an officer with the Royal Field Artillery of the British Army during World War I, spent nearly 20 years with the Egyptian Survey department during the 1920s and 1930s extensively mapping large areas of previously unmapped desert. In 1931, Clayton was running triangulation from Wadi Halfa to Uweinat when he came across refugees fleeing from the Italian occupation of Kufra, via Uweinat and helped save many from death in the arid desert. Clayton had collaborated extensively with Ralph Bagnold in the preparation and mapping associated with Bagnold's pre-war exploration trips.
At the start of the war Clayton was a government surveyor in Tanganyika. Bagnold had him returned to Egypt because of his detailed knowledge of the Western Desert. He was commissioned into the Intelligence Corps and served in the British Army's Long Range Desert Group (LRDG).
Death
Pat Clayton died on 17 March 1962 at the age of 65 of an aneurysm.
