Harry S. Truman
Born in a small farm of Missouri on May 8, 1884, Harry S. Truman became the 33rd President of the United States on April 12, 1945. Under his lead, the U.S. successfully won WWII. In WWI, Truman served in combat as an artillery officer in France. Following the war, he briefly owned a haberdashery, or a botton shop, and became a democrat in Missouri. Starting his political career, he was a county official, then in 1934, he became a U.S. Senator. He created the Truman Committee, which exposed waste, fraud, and corruption in wartime contracts. The creation of the committee gained him national prominence. Soon after Truman assumed presidency, Germany surrendered. However, the war with Japan was expected to last for a while longer.
