Mark Spitz becomes the first competitor to win seven medals at a single Olympic Games.

Mark Andrew Spitz is an American former competitive swimmer and nine-time Olympic champion. He was the most successful athlete 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. Phelps, like Spitz, set seven world records.

The modern Olympic Games are the world's preeminent international sporting events. They feature summer and winter sports competitions in which thousands of athletes from around the world participate in a variety of competitions. The Olympic Games, open to both amateur and professional athletes, involves more than 200 teams, each team representing a sovereign state or territory. By default, the Games generally substitute for any world championships during the year in which they take place. The Olympics are staged every four years. Since 1994, they have alternated between the Summer and Winter Olympics every two years during the four-year Olympiad.
