This spring OSMOS Address, a project space in the East Village run by curator and editor Cay Sophie Rabinowitz, presents the first solo exhibition in New York of Sibylle Bergemann (1941-2010). The Berlin born-and-raised photographer, who studied at the Kunsthochschule Berlin-Weißensee in the 60s, began working for the East German women’s magazine Sibylle (coincidentally her name) in the 70s and, along with her husband Arno Fischer, became the center of a community of artists, designers, and photographers living in the German Democratic Republic. In 1990, the year of Germany’s reunification, she co-founded Ostkreuz, an agency which now represents a score of photographers.
