Arp, Hans

French abstract painter, sculptor, and poet. He was one of the founders of the Dada movement in 1916, and was later associated with the Surrealists. Using chance and automatism, Arp developed an abstract sculpture whose sensuous shapes suggest organic forms. In many of his works, in particular his early collages, he collaborated with his wife Sophie Taeuber-Arp (1889–1943).

From 1916 to 1919 Arp took a leading role in Dada activities in Zürich, Switzerland. He started making wood reliefs, sometimes painted, with simple organic forms. In 1925 he exhibited with the surrealists, but he was also in contact with abstract artists. From 1930 onwards he also made free-standing sculpture in stone, bronze, and wood.
