Harry S. Truman was the 33rd president of the United States. He assumed presidency after the sudden demise of President Franklin D. Roosevelt, and was in the office from 1945 to 1953. He oversaw America’s participation in ‘World War II’ and is infamous for approving the use of atomic weapons against Japan. Born in an ordinary family in Missouri, Truman did not complete college education as he dropped out of a business college. After graduating from high school, he took up a number of jobs before volunteering for military duty during ‘World War I.’ Thanks to his valor and bravery, he won respect and admiration and was made the captain. Post ‘World War I,’ Truman forayed into business but was not very successful in his venture. He then entered politics and was elected to the United States Senate in 1934, and was re-elected in 1940. President Roosevelt chose Truman as his running mate for the 1944 presidential election and they won the elections. Truman served as the vice president for just eighty-two days as the untimely demise of President Roosevelt thrust him to the chair of presidency. Truman’s reelection in the 1948 presidential elections is considered to be one of the greatest election upsets in American history; he defied all predictions and public opinion polls to emerge victorious. After the completion of his second term, he returned to Independence, Missouri where he spent the rest of his life.
