France, 19th and early 20th century: Post-Impressionism; Switzerland, 20th century

Oskar Reinhart's rather conservative approach prevented him from collecting the more avant-garde art produced by the Post-Impressionists and his own contemporaries. Hence the few twentieth-century works in the collection tend to reflect his orientation towards traditional artistic values.

Vincent van Gogh (1853-1890), Henri de Toulouse-Lautrec (1864-1901), Edouard Vuillard (1868-1940), Maurice Utrillo (1883-1955), Pablo Picasso (1881-1973), André Derain (1880-1954), Karl Walser (1877-1943)
