Herbert Hoover, the 31st president of the United States, was also left-handed.
Harry S. Truman, 33rd president of the United States, wrote left-handed as a child, but was forced by his parents to learn to write right-handed.
Only in the last few decades has left-handedness become socially acceptable. Before that, parents and teachers would force children to become righties. They had little choice, too: back in the day, all everyday items were designed for righties.
Gerald Ford, the 38th president of the United States, was left-handed, but switched back and forth.
Of his handedness, Gerald Ford once said, "For as long as I can remember, I have been left-handed when I've been sitting down and right-handed standing up."
Ronald Reagan, the 40th president of the United States, is left-handed, but was forced by schoolteachers to write right-handed.
George H.W. Bush was the second consecutive left-handed president of the United States.
Bill Clinton was the third consecutive left-handed person to hold the office.
Barack Obama, the 44th president of the United States, had jokes for anyone who noticed he was left-handed when he first entered office.
