Sir Winston Leonard Spencer-Churchill, (1874 – 1965) was a British politician and statesman known for his leadership of the United Kingdom during the Second World War. He is widely regarded as one of the great wartime leaders. He served as Prime Minister twice (1940–45 and 1951–55). A noted statesman and orator, Churchill was also an officer in the British Army, a historian, a writer, and an artist. During the 1930s, Churchill took the lead in warning about the danger from Hitler and in campaigning for rearmament. On the outbreak of World War II, he was again appointed First Lord of the Admiralty. Following the resignation of Neville Chamberlain on 10 May 1940, Churchill became Prime Minister. His steadfast refusal to consider defeat, surrender or a compromise peace helped inspire British resistance, especially during the difficult early days of the War when Britain stood alone in its active opposition to Hitler. Churchill was particularly noted for his speeches and radio broadcasts, which helped inspire the British people.
