Braque, Gris, Léger and Picasso at an early point, thus mentally and financially supporting the artists. In 1918 he opened his gallery "L'Effort Moderne" and organized exhitions of i.a. Laurens, Léger, Braque, Gris, Picasso, Mondrian and Picabia. In 1941 he was forced to close his gallery due to the antisemitic laws.
