Who was Truman?
Born in Missouri in 1884, Truman farmed, failed as a haberdasher, commanded an artillery battery in France and rose through the Kansas City machine to the Senate, where he made his name investigating waste in war contracts. He was Vice-President for eighty-two days, had met Roosevelt twice, and learned of the Manhattan Project only after Roosevelt died in April 1945. He authorised the use of the atomic bomb, attended Potsdam, announced the doctrine to Congress in March 1947 to move an appropriation for Greece and Turkey, signed the Marshall Plan legislation, ordered the Berlin airlift in June 1948, desegregated the armed forces by executive order the same year, and took the United States into Korea in 1950. He relieved MacArthur in April 1951.
