Marcel Duchamp (1887–1968) was a French artist whose revolutionary contributions to modern art extended beyond his iconic readymades to his explorations in photography. Duchamp often used photography as a conceptual tool, challenging conventions and engaging in artistic dialogues through experimentation. Collaborating closely with Man Ray, Duchamp produced enigmatic self-portraits, playful double exposures, and provocative staged photographs. His photographic alter ego, Rrose Sélavy, reflected his fascination with identity and the absurd. Though primarily celebrated for reshaping the landscape of contemporary art, Duchamp’s photographic works remain integral to understanding his relentless inquiry into the nature of representation and perception.
