American Eddie Eagan is the only person to win a gold medal at both the Summer and Winter Olympic Games in different events. The Harvard and Oxford University law graduate won a gold medal in light-heavyweight boxing at Antwerp in 1920 and then, 12 years later, was a member of the United States four-man bobsleigh team that won at Lake Placid. Later, the Denver-born Eagan became a lawyer, and served in the army as a colonel during the Second World War.
