The German painter-poet Max Ernst was a member of the dada movement and a founderof surrealism. A self-taught artist, he formed a Dada group in Cologne, Germany, with other avant-garde artists. He pioneered a method called frottage, in which a sheet of paper is placed on the surface of an objectand then penciled over until the texture of the surface is transferred. In 1925, he showed his work at the first surrealist painting exhibition in Paris.
