Mary Kok

These included: 440 yd freestyle 880 yd freestyle 800 m freestyle 1760 yd freestyle 100 yd butterfly 100 m butterfly 400 yd individual medley 400 m individual medley 1 relay

Kok was to swim in the 1956 Summer Olympics in Melbourne for the Dutch Olympic Team until the night before she was to depart when the Netherlands boycotted the competition over Russia's invasion of Hungary. In 2016 Kok, along with other athletes whose athletic careers were affected by the boycott were honoured by the Hungarian government. Kok said in her speech, she had always felt that her gold medal was at the bottom of the swimming pool in Melbourne, but that the Hungarian people gave her the feeling that the honorary medal was given to her wholeheartedly. In 1960, Kok became the first Dutch woman to swim across the English Channel.

On 28 December 1962, she married Kees Oudegeest, and later became a swimming coach.

In 2015, Kok was invited by the Dutch Sports Federation to be recognised at their annual Athlete of the Year event. Kok won Athlete of the Year in 1955 at the age of 15 years.
