Rie Mastenbroek

Hendrika Wilhelmina Rie Mastenbroek was a Dutch swimmer, born in Rotterdam on 26 February 1919 and died there in 2003, who became a triple Olympic champion at the age of seventeen. Coached by Ma Braun, who had earlier guided her own daughter to Olympic gold, she won three gold medals and a silver at the 1934 European Championships and repeated that haul at the 1936 Summer Olympics, taking the 100 m freestyle, 400 m freestyle and 4 by 100 m freestyle relay and finishing second in the 100 m backstroke behind her teammate Nida Senff. She broke nine world records during her career, six in backstroke and three in freestyle. After becoming a swimming instructor in 1937 she lost her amateur status and could no longer compete. She entered the International Swimming Hall of Fame in 1968, received the Olympic Order in 1997, and the Rie Mastenbroek Trophy is named after her.
