Alexander ("Alec") Frederick Douglas-Home (/ˈhjuːm/ HYOOM), KT, PC (2 July 1903 – 9 October 1995) was a British Conservative politician who served as Prime Minister from October 1963 to October 1964. His reputation, however, rests more on his two spells as the UK's foreign minister than on his brief and uneventful premiership.
Within six years of entering the House of Commons in 1931, Douglas-Home (then called by the courtesy title Lord Dunglass) became parliamentary aide to Neville Chamberlain, witnessing at first hand Chamberlain's efforts as Prime Minister to preserve peace through appeasement in the two years before the outbreak of the Second World War. In 1940 Dunglass was diagnosed with spinal tuberculosis and was immobilised for two years. By the later stages of the war he had recovered enough to resume his political career, but lost his seat in the general election of 1945. He regained it in 1950, but the following year he left the Commons when, on the death of his father, he inherited the earldom of Home and thereby became a member of the House of Lords. Under the premierships of Winston Churchill, Anthony Eden and Harold Macmillan he was appointed to a series of increasingly senior posts, including Leader of the House of Lords and Foreign Secretary. In the latter post, which he held from 1960 to 1963, he supported United States resolve in the Cuban Missile Crisis and was the United Kingdom's signatory of the Partial Nuclear Test Ban Treaty in August 1963.
