Stieglitz encouraged him. Duchamp became his closest (and lifelong) friend, and collaborator, and told him of a Paris hotel room just vacated by Tzara. Éluard, Cocteau, Picasso, Dalí, Brassai and Breton, as well as Tzara, were among his Paris circle of friends. Boiffard, Abbott and Miller all worked as his assistant, Miller becoming his lover, collaborator then friend for life. Brandt, whom Pound said he’d introduced, was more of a student. Atget disapproved of Ray’s promotion of his work. Oppenheim posed for him, Ernst married in a double ceremony with him, and Antheil recalled him punching someone at a première.
