U.S. swimmer Mark Spitz wins his seventh gold medal at the 1972 Summer Olympics in Munich. Spitz swam the fly leg of the 400-meter medley relay, and his team set a new world-record time of 3 minutes, 48.16 seconds. Remarkably, Spitz also established new world records in the six other events in which he won the gold. At the time, no other athlete had won so many gold medals at a single Olympiad. The record would stand until Michael Phelps took home eight gold medals at the Beijing Games in 2008.
