Mark Andrew Spitz (born February 10, 1950) is an American former competition swimmer, nine-time Olympic champion, and former world record-holder in multiple events. He won seven gold medals at the 1972 Summer Olympics in Munich, an achievement only surpassed by Michael Phelps who won eight golds at the 2008 Summer Olympics in Beijing. Spitz set new world records in all seven events in which he competed in 1972, a record that still stands. Since the year 1900, no other swimmer has ever gained so great a percentage of all the medals awarded for Olympic events held in a single Games.🏊💫
