Why they rank here
For 36 years the standard by which all Olympic swimmers were judged. At the Munich 1972 Games, Spitz won seven gold medals in seven events, every single one in world-record time, a perfect performance not surpassed until Phelps in 2008. Across two Olympics he collected nine golds and 11 medals in total, and over his career he set 33 world records in freestyle and butterfly. He retired at just 22, at his peak, before the World Championships even existed (the first were held in 1973), which is why his title tally sits outside that column. His combination of sprint speed and butterfly power, and the sheer perfection of Munich, keeps him among the immortals despite his short career.
