What did he accomplish?

He made some Surrealist films with Luis Buñuel. They were called Un Chien andalou (1928) and L'Âge d'or (1930). The Persistence of Memory (1931) was by far his most famous painting. After this painting he started to shine. During the Surrealist movement when he adopted a more academic style, he later designed stage sets, jewelry, interiors, and book illustrations. His highly accessible art and the publicity attracted by the eccentricity, exhibitionism, and flamboyant behavior he cultivated throughout his life made him extremely wealthy. He will always be remembered for his bizarre images and his soft watches.
