Career

In 1949 and in 1950 she was part of the Dutch team that set a new world record in the now obsolete 3×100 medley relay event. She competed in the 200 m breaststroke at the 1952 Olympics and finished in eighth place. In those years it was allowed to use the butterfly stroke in breaststroke events, as the 1952 Olympic winners did.

She retired shortly thereafter.
