Spitz set new world records in all seven events in which he competed in 1972. Spitz holds more medals than any other Jew in the history of the Olympics.
Between 1968 and 1972, Spitz won nine Olympic golds, a silver, and a bronze; five Pan American golds; 31 Amateur Athletic Union (AAU) titles; and eight National Collegiate Athletic Association (NCAA) titles. During those years, he set 35 world records, but two were in trials and unofficial. He was named World Swimmer of the Year in 1969, 1971, and 1972 by Swimming World Magazine. He was the third athlete to win nine Olympic gold medals.
