Sir Winston Leonard Spencer-Churchill, KG, OM, CH, TD, PC, FRS was a British politician known chiefly for his leadership of the United Kingdom during World War II. He is widely regarded as one of the great wartime leaders. He served as Prime Minister from 1940 to 1945 and again from 1951 to 1955. A noted statesman and orator, Churchill was also an officer in the British Army, a historian, writer and artist. To date, he is the only British Prime Minister to have received the Nobel Prize in Literature, and the first person to be recognised as an honorary citizen of the United States.
