He was a member of the League for Proletarian Culture (1919-1920). In 1921 he travelled with Jan Appel to participate in the 3rd World Congress of the Comintern in 1921 as a delegate of the Communist Workers Party of Germany. This involved hijacking the SS Senator Schröder to go to Murmansk, Soviet Russia, rather than fishing near Iceland.
