Marianne Jouvenel
She started swimming in 1927 after her mother found out about the collective lessons of Mouettes de Paris. In July 1929 she obtained her school swimming certificate. When she was thirteen years old she swam every day in the summer and three times per week in the winter in the Lutetia swimming pool. In addition to swimming she also did stretching exercises, cycling and skiing. She had classical opera dance classes by professor Paul Raymond.
