Mark Spitz

Mark Andrew Spitz is an American former competitive swimmer and nine-time Olympic champion. He was the most successful competitor at the 1972 Summer Olympics in Munich, winning seven gold medals, each in world-record time. This achievement set a record that lasted for 36 years, until it was surpassed by fellow American Michael Phelps, who won eight golds at the 2008 Summer Olympics in Beijing, though Phelps, like Spitz, set seven world records.
