In the turmoil of the 1920s and '30s, Claude Cahun challenged gender stereotypes with her powerful photographs, photomontages and writings: work that appears contemporary when viewed with 21st-century eyes. Cahun wrote poetry and prose for major French literary magazines, worked in avant-garde theatre, and was both a comrade and critical outsider of the Surrealists. Her artful resistance tactics during the Second World War mocked and disrupted the Nazi occupiers of the Isle of Jersey, where she lived and worked collaboratively with Marcel Moore, her stepsister, lover and life partner. Together they created some of the most compelling photographs and photomontages of the period. This is the first work in English to tell the full story of Claude Cahun's art and life. The book includes generous reproductions of work by Cahun and other renowned photographers, as well as some of her writings, here translated into English for the first time. Exist Otherwise is a significant contribution to our understanding of photography, Surrealism and the histories of women artists and queer culture.
