Nida Senff

Nida Senff was a Dutch backstroke swimmer, born Dina Willemina Jacoba Senff on 3 April 1920 and died on 27 June 1995. She won the 100 metre backstroke at the 1936 Summer Olympics in Berlin, in a final remembered for a mistake: she missed the turning point, went back to touch the wall, and still managed to win. Senff was Dutch national champion in the 100 metre backstroke in 1935 and 1937, and in 1936 and 1937 she set five world records across the 100 metre, 150 yard and 200 metre backstroke distances. At Berlin she raced alongside her compatriot Rie Mastenbroek, and both Dutch women reached the final. She was inducted into the International Swimming Hall of Fame in 1983. Her single Olympic appearance produced one gold medal, which makes her one of the champions of the 1936 Games in the pool.
