Truman (May 8, 1884--December 26, 1972) was the 33rd President of the United States (1945--1953), taking office upon the death of Franklin D. Roosevelt . A World War I veteran, he assumed the presidency during the waning months of World War II and the beginning of the Cold War . He is known for implementing the Marshall Plan to rebuild the economy of Western Europe, for establishing the Truman Doctrine and NATO against Soviet and Chinese Communism, and for intervening in the Korean War . In domestic affairs, he was a moderate Democrat whose liberal proposals were a continuation of Franklin Roosevelt's New Deal, but the conservative - dominated Congress blocked most of them . He used the veto power 180 times, more than any president since and saw 12 overridden by Congress; only Grover Cleveland and Franklin D. Roosevelt used the veto more often, and only Gerald Ford and Andrew Johnson saw so many veto overrides . He is the only world leader to have used nuclear weapons in war . He desegregated the U.S. Armed Forces, supported a newly independent Israel and was a founder of the United Nations . </P> <P> Truman was born in Lamar, Missouri, and spent most of his youth on his family's 550 - acre farm near Independence . In the last months of World War I, he served in combat in France as an artillery officer with his National Guard unit . After the war, he briefly owned a haberdashery in Kansas City, Missouri, and joined the Democratic Party and the political machine of Tom Pendergast . Truman was first elected to public office as a county official in 1922, and then as a U.S. Senator in 1934 . He gained national prominence as chairman of the Truman Committee, formed in March 1941, which aimed to find and correct waste and inefficiency in Federal Government wartime contracts . After serving as a United States Senator from Missouri (1935--1945) and briefly as Vice President (1945), he succeeded to the presidency on April 12, 1945, upon the death of Franklin D. Roosevelt . Germany surrendered just a few weeks after he assumed the presidency but the war with Imperial Japan raged on and was expected to last at least another year . Truman approved the use of atomic bombs to end the fighting and to spare the U.S. and Japanese lives that would inevitably be lost in the planned invasion of Japan and Japanese - held islands in the Pacific . This decision and the numerous resulting issues remain the subject of debate to this day . Critics argue that the nuclear bombings were unnecessary since conventional methods could have achieved surrender, while defenders assert that it ultimately saved more lives that would have been lost during an invasion . Truman presided over an unexpected surge in economic prosperity as the U.S. sought readjustment after long years of depression and war . His presidency was a turning point in foreign affairs as the United States engaged in an internationalist foreign policy and renounced isolationism . Truman helped found the United Nations in 1945, issued the Truman Doctrine in 1947 to contain Communism and got the $13 billion Marshall Plan enacted to rebuild Western Europe . His political coalition was based on the white South, labor unions, farmers, ethnic groups and traditional Democrats across the North . Truman was able to rally these groups of supporters during the 1948 presidential election and win a surprise victory that secured a presidential term in his own right . </P>
