1968 Mexico City Games, 1972 Munich Games
Medal count: Nine golds, one silver, one bronze
Spitz won four medals, including two gold, at the 1968 games, but it was his performance four years later that made him one of the most successful Olympians of all time. He won gold in all seven events in which he participated, setting world records with each victory. The seven golds in one Olympiad was a record until Michael Phelps won eight in 2008.
