Schwob adopted the gender-ambiguous name Claude Cahun in 1917 and is best known for self-portraits, in which Cahun assumed a variety of personae.
Cahun's work was both political and personal, and often undermined traditional concepts of static gender roles. In their autobiography, Disavowals, they explained, "Masculine? Feminine? It depends on the situation. Neuter is the only gender that always suits me."
During WWII, Cahun was also active as a resistance worker and propagandist.
Born in Nantes in 1894, Cahun was born into a provincial but prominent intellectual Jewish family. Avant-garde writer Marcel Schwob was their uncle and Orientalist David Léon Cahun was their great-uncle. When Cahun was four years old, their mother, Mary-Antoinette Courbebaisse, began suffering from mental illness, which ultimately led to her permanent internment at a psychiatric facility. In their mother's absence, Cahun was brought up by their grandmother, Mathilde Cahun.
Cahun attended a private school (Parsons Mead School) in Surrey after experiences with anti-Semitism at their high school in Nantes. They attended the University of Paris, Sorbonne. They began making photographic self-portraits as early as 1912 (aged 18), and continued taking images of themself through the 1930s.
Around 1919, they changed their 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, they settled in Paris with lifelong partner and step-sibling Suzanne Malherbe, who adopted the pseudonym Marcel Moore.:69 For the rest of their lives together, Cahun and Moore collaborated on various written works, sculptures, photomontages and collages. The two published articles and novels, notably in the periodical Mercure de France, and befriended Henri Michaux, , and Robert Desnos.
Around 1922 Claude and Moore began holding artists' salons at their home. Among the regulars who would attend were artists Henri Michaux and André Breton and literary entrepreneurs Sylvia Beach and Adrienne Monnier.
Cahun's works encompassed writing, photography, and theatre. They are most remembered for their highly staged self-portraits and tableaux that incorporated the visual aesthetics of Surrealism. During the 1920s Cahun produced an astonishing number of self-portraits in various guises such as aviator, dandy, doll, body builder, vamp and vampire, angel, and Japanese puppet.:66
Many of Cahun's portraits feature the artist looking directly at the viewer, head shaved, often revealing only head and shoulders (eliminating body from the view), and a blurring of gender indicators and behaviors which serve to undermine the patriarchal gaze. Scholar Miranda Welby-Everard has written about the importance of theatre, performance, and costume that underlies Cahun's work, suggesting how this may have informed the artist's varying gender presentations.
Cahun's published writings include "Heroines," (1925) a series of monologues based upon female fairy tale characters intertwined with witty comparisons to the contemporary image of women; Aveux non avenus, (Carrefour, 1930) a book of essays and recorded dreams illustrated with photomontages; and several essays in magazines and journals.
In 1932 Cahun joined the Association des Écrivains et Artistes Révolutionnaires, where they met André Breton and René Crevel. Following this, they started associating with the surrealist group, and later participated in a number of surrealist exhibitions, including the London International Surrealist Exhibition (New Burlington Gallery) and Exposition surréaliste d'Objets ( Gallery, Paris), both in 1936. Cahun's photograph from the London exhibition of Sheila Legge standing in the middle of Trafalgar Square, their head obscured by a flower arrangement and pigeons perching on their outstretched arms, appeared in numerous newspapers and was later reproduced in a number of books. In 1934, Cahun published a short polemic essay, Les Paris sont Ouverts, and in 1935 took part in the founding of the left-wing anti-fascist alliance Contre Attaque, alongside André Breton and Georges Bataille. Breton called Cahun "one of the most curious spirits of our time."
In 1994 the Institute of Contemporary Arts in London held an exhibition of Cahun's photographic self-portraits from 1927–47, alongside the work of two young contemporary British artists, Virginia Nimarkoh and Tacita Dean, entitled Mise en Scene. In the surrealist self-portraits, Cahun represented themself as an androgyne, nymph, model, and soldier.
In 2007, David Bowie created a multi-media exhibition of Cahun's work in the gardens of the General Theological Seminary in New York. It was part of a venue called the Highline Festival, which also included offerings by Air, Laurie Anderson, and Mike Garson. Bowie said of Cahun:
You could call her transgressive or you could call her a cross dressing Man Ray with surrealist tendencies. I find this work really quite mad, in the nicest way. Outside of France and now the UK she has not had the kind of recognition that, as a founding follower, friend and worker of the original surrealist movement, she surely deserves." 
Collaboration with Marcel Moore
Cahun's work was often a collaboration with Marcel Moore. Cahun and Moore collaborated frequently, though this often goes unrecognized. It is believed that Moore was often the person standing behind the camera during Cahun's portrait shoots and was an equal partner in their collages.
With the majority of the photographs attributed to Cahun coming from a personal collection, not one meant for public display, it has been proposed that these personal photographs allowed for Cahun to experiment with gender presentation and the role of the viewer to a greater degree.
World War II activism
In 1937 Cahun and Moore settled in Jersey. Following the fall of France and the German occupation of Jersey and the other Channel Islands, they became active as resistance workers and propagandists. Fervently against war, the two worked extensively in producing anti-German fliers. Many were snippets from English-to-German translations of BBC reports on the Nazis' crimes and insolence, which were pasted together to create rhythmic poems and harsh criticism. The couple then dressed up and attended many German military events in Jersey, strategically placing their in soldier's pockets, on their chairs, and in cigarette boxes for soldiers to find. Additionally, they inconspicuously crumpled up and threw their fliers into cars and windows. In many ways, Cahun and Moore's resistance efforts were not only political but artistic actions, using their creative talents to manipulate and undermine the authority which they despised. In many ways, Cahun's life's work was focused on undermining a certain authority; however, their activism posed a threat to her physical safety.
In 1944, Cahun and Moore were arrested and sentenced to death, but the sentence was never carried out as the island was liberated from German occupation in 1945. However, Cahun's health never recovered from their treatment in jail, and they died in 1954. Cahun is buried in St Brelade's Church with partner Marcel Moore.
Social critique and legacy
Cahun made work for themself and did not want to be famous. It wasn't until 40 years after her death that Cahun's work became recognized. In many ways, Cahun's life was marked by a sense of role reversal, and like many early queer pioneers, their public identity became a commentary upon the public's notions of sexuality, gender, beauty, and logic. their adoption of a gender neutral name and their androgynous self-portraits display a revolutionary way of thinking and creating, experimenting with the audience's understanding of photography as a documentation of reality. Their poetry challenged gender roles and attacked the increasingly modern world's social and economic boundaries. Also, Cahun's participation in the Parisian Surrealist movement diversified the group's artwork and ushered in new representations. Most Surrealist artists were men, and their primary images were of women depicted as isolated symbols of eroticism. Cahun epitomized the chameleonic and various possibilities of genders and of the body. Their photographs, writings, and general life as an artistic and political revolutionary continue to influence artists.
Cahun's collected writings were published in 2002 as Claude Cahun – Écrits (ISBN 2-85893-616-1), edited by François Leperlier.
