While working as the first director of the Moreau Museum in Paris, to which he was appointed in 1903 in accordance with Moreau's will, he produced paintings with such subjects as clowns and prostitutes. From 1914, he began to make prints commissioned by the art dealer Ambroise Vollard. After 1918, he devoted himself to painting religious subjects.
