From Thomas Jefferson Encyclopedia
Thomas Jefferson was right-handed. One of his most famous letters, however - sometimes referred to as the "Head and Heart" letter - was written entirely with his left hand after he had broken his right wrist in Paris in 1786. Although the letter is surprisingly legible, it is clearly different from his normal handwriting.
