Eddie Eagan

Eagan is still the only athlete to win gold at both the Summer and Winter Olympics in different sports: light-heavyweight boxing at Antwerp in 1920 and four-man bobsleigh at Lake Placid in 1932, having barely tried the sled before. The link was nerve and power at the push start rather than technique. A Rhodes Scholar and lawyer, he is the original example of how far raw athletic confidence can carry someone into a new sport.
