Amy Van Dyken
1996 Atlanta Games, 2000 Sydney Games
Medal count: Six golds
Van Dyken, who started swimming as a way to combat her asthma, won four events in 1996 – the 50 meter freestyle, 100 meter butterfly, 4×100-meter freestyle, and 4×100-meter medley – to become the first woman to ever earn four gold medals in a single Olympics. Despite shoulder problems, she won two more golds when the women repeated in the relays at the 2000 games.
