In 2011, the Jean and Suzanne Planque Foundation deposited at the Granet Museum the funds of Jean Planque (1910-1998), a major Swiss collector, made up of some 300 paintings, drawings and sculptures since the Impressionists and post-Impressionists (Cézanne, Monet, Van Gogh, Degas) to major artists of the 20th century such as Bonnard, Picasso, Braque, Léger, de Staël or Dubuffet.
