Harry S. Truman (May 8, 1884 – December 26, 1972) was the 33rd president of the United States from 1945 to 1953, succeeding upon the death of Franklin D. Roosevelt after serving as vice president. He implemented the Marshall Plan to rebuild the economy of Western Europe, and established the Truman Doctrine and NATO. Truman was born in Lamar, Missouri, on May 8, 1884, the oldest child of John Anderson Truman and Martha Ellen Young Truman. He was named for his maternal uncle, Harrison 'Harry' Young. His middle name, 'S', honors his grandfathers, Anderson Shipp Truman and Solomon Young. A brother, John Vivian, was born soon after Harry, followed by sister Mary Jane. Truman's ancestry is primarily English with some Scots-Irish, German, and French.
