Northwestern Swimming and Diving has earned tremendous success over time. Three-time All-American Olivia Rosendahl won the NCAA Women's Platform Diving championship in both 2017 and 2018, and the Wildcats have been represented in each of the last three Summer Olympic Games, most recently by swimmers Valerie Gruest-Slowing and Jordan Wilimovsky in Rio in 2016. In the summer before his senior season, Wilimovsky became the first American to compete in both indoor and outdoor swimming events in the same Olympics. In 2015, Wilimovsky became the world champion in 10 km water race. Matt Grevers, a Northwestern alum, won two gold medals (100-meter backstroke, 400-meter medley relay) and a silver medal (400-meter freestyle relay) at the 2012 London Olympic Games. At the 1924 Paris Olympic Games, three Northwestern alums won gold medals- Ralph Breyer (4 x 200-meter freestyle relay), Sybil Bauer (100-meter backstroke) and Robert “Bob” Skelton (200-meter breaststroke).
