He was a painter, in oils and watercolours, etcher and book illustrator, renowned in France, Britain and America. He was one of the modernists chosen to exhibit in the Armory Show in New York in 1913. His monumental, dark-toned canvases of nudes, still lifes and landscapes, made with a thick impasto, are marked by a realism firmly rooted in the French tradition. His style and palette lightened, particularly after 1925, and his elegant watercolours and prints were created with a great spontaneity.
