Roger Duvoisin was born in Geneva. He studied at the École nationale supérieure des Arts Décoratifs in Paris.

Duvoisin wrote his first book in America. In 1947, the book he illustrated, White Snow, Bright Snow, written by Alvin Tresselt, was awarded the prestigious American prize for picture books, the Caldecott Medal.
