Harry Truman, pianist

Truman was one of the hardest-working presidents when it came to his instrument: He would wake up at 5AM and practice piano for two hours a day! He also wasn't afraid to boast about his skills. In October 1945, he performed for a group of Methodist women at a county fair and said, "When I played this, Stalin signed the Potsdam Agreement." Less wholesomely, he also once said, "My choice early in life was either to be a piano-player in a whorehouse or a politician. And to tell the truth, there's hardly any difference."
