Mark Spitz, a swimmer from the United States, set a world record when he won seven gold medals (while on the way to setting a new world record for each of his seven gold medals) in a single Olympics, bringing his lifetime total to nine (he had won two golds in Mexico City’s Games four years earlier). Being Jewish, Spitz was asked to leave Munich before the closing ceremonies for his own protection, after fears arose that he would be an additional target of those responsible for the Munich massacre. Spitz’s record stood until 2008, when it was beaten by Michael Phelps who won 8 gold medals in the pool.
