Sir Winston Leonard Spencer-Churchill, KG, OM, CH, TD, FRS, PC (Can) was a British politician who served as Prime Minister of the United Kingdom from 1940 to 1945, and again from 1951 to 1955. A noted statesman, orator and strategist, Churchill was also an officer in the British Army. A prolific author, he won the Nobel Prize in Literature in 1953 for his own historical writings, "for his mastery of historical and biographical description as well as for brilliant oratory in defending exalted human values." Out of respect for the well-known American author, Winston Churchill, Winston S. Churchill offered to use his middle initial in any works that he authored.
