“Masculine? Feminine?” questioned the artist Claude Cahun, “It really depends on the situation. Neuter is the only gender that always suits me.” Cahun was born Lucy Schwob in 1894, but in 1914 she changed her name to Claude Cahun because it was gender neutral. This was 100 years before the subjects of gender, identity, and sexuality were common currency. Cahun was a surrealist photographer, sculptor, and writer whose work could be unsettling, especially her self-portraits, which often involved cross-dressing. She was also a bold resistance worker during W.W. II. Cahun died in 1954, and though she never sought fame, her work went on to influence David Bowie, Cindy Sherman, and Nan Goldin. In Rotterdam, 60 photographs by the artist are on view, along with archival material. —Elena Clavarino
