Claude Cahun (born Lucy Renee Mathilde Schwob, 25 October 1894 – 8 December 1954) was a French surrealist photographer, sculptor, and writer.
Schwob adopted the pseudonym Claude Cahun in 1914. She is best known as a writer and self-portraitist, who assumed a variety of performative personae.
Cahun's work is both political and personal. In Disavowals, she writes: "Masculine? Feminine? It depends on the situation. Neuter is the only gender that always suits me."
During World War II, Cahun was also active as a resistance worker and propagandist.
