Maris, Willem (1844 - 1910), was a pupil of his two brothers and was influenced by Mauve. His subjects are almost entirely confined to meadows and cattle. In his later years he became a leader of Dutch Impressionism, urging his pupils - among them Breitner - to paint in the open air and to use vivid colours. Examples of works by all three brothers are in the Gemeentemuseum in The Hague
