The intense colourism of the works he painted between 1900 and 1905 brought him notoriety as one of the Fauves (French for "wild beasts"). Many of his finest works were created in the decade or so after 1906, when he developed a rigorous style that emphasized flattened forms and decorative pattern. In 1917, he relocated to a suburb of Nice on the French Riviera, and the more relaxed style of his work during the 1920s gained him critical acclaim as an upholder of the classical tradition in French painting.Wattenmaker, Richard J.; Distel, Anne, et al. (1993). Great French Paintings from the Barnes Foundation. New York: Alfred A. Knopf. . p. 272 After 1930, he adopted a bolder simplification of form. When ill health in his final years prevented him from painting, he created an important body of work in the medium of cut paper collage.
