Claude Cahun (klod ka.œ̃, 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. Cahun is best known as a writer and self-portraitist, who assumed a variety of performative personae. In her writing she consistently referred to herself as "elle" (she), and this article follows her practice; but she also said that her actual gender was fluid. For example, in Disavowals, Cahun writes: "Masculine? Feminine? It depends on the situation. is the only gender that always suits me." Cahun is most well known for her androgynous appearance, which challenged the strict gender roles of her time. During World War II, Cahun was also active as a resistance worker and propagandist. Cahun was born in Nantes in 1894, into a well-off literary Jewish family. Avant-garde writer Marcel Schwob was her uncle and Orientalist David Léon Cahun was her great-uncle. When Cahun was four years old, her mother, Mary-Antoinette Courbebaisse, began suffering from mental illness, which ultimately led to her mother's permanent internment at a psychiatric facility. In her mother's absence, Cahun was brought up by her grandmother, Mathilde. Cahun attended a private school (Parsons Mead School) in Surrey after experiences with antisemitism at high school in Nantes. She attended the University of Paris, Sorbonne. She began making photographic self-portraits as early as 1912 (aged 18), and continued taking images of herself throughout the 1930s. Around 1914, she changed her name to Claude Cahun, after having previously used the names Claude Courlis (after the curlew) and Daniel Douglas (after Lord Alfred Douglas). During the early 1920s, she settled in Paris with lifelong partner Suzanne Malherbe, who adopted the pseudonym Marcel Moore. The two became step-sisters in 1917 after Cahun's divorced father and Moore's widowed mother married, eight years after Cahun and Moore's artistic and romantic partnership began.
