From 1942 until 1945 she was an apprentice at Boissonnas in Geneva, known as the house of a "dynasty" of photographers . In 1945 Sabine Weiss moved to a studio in Geneva, but in 1946 she decided to leave the city of her childhood to live in Paris. She knew there was no turning back. She asked Willy Maywald to become her assistant. In 1949, she met the painter Hugh Weiss and realized right away that she would spend her life with him. Sabine Weiss left Maywald, where she mastered her craft and started a long career, experimenting fashion, photojournalism, advertising and everything else she was asked to do.
