Huelsenbeck helped introduce Hausmann to Dada, but they went on to feud for forty years. Heartfield, Grosz and Baader were fellow-members of the Berlin Dada scene, Richter then arriving from Zürich and Schwitters from Hanover. Schwitters remained a correspondent until his death; Moholy-Nagy and Richter were also lifelong friends to Hausmann. Höch was his lover. He had what Richter described as “a remarkable, cold-blooded relationship” with Jung. As a latter-day recluse in France, among his correspondents from a younger generation of artists were Maciunas, Chopin, Spoerri, Johns, Houédard and Themerson.
