Alexander Hamilton was a founding father of the United States who made major contributions to the country's founding and early development. He wrote most of the Federalist Papers and served as the first Secretary of the Treasury. However, in 1804, his ego led him to accept a duel challenge from Aaron Burr, which resulted in Hamilton's death from a gunshot wound later that day at the age of 47. Though Hamilton was highly intelligent and accomplished, his pride ultimately cost him his life in a duel, demonstrating how even brilliant minds can be destroyed by ego.
