In 1908 Jacques Biederer, a Czech immigrant, moved to Paris and set up a photography studio. He was joined by his brother Charles in 1913 who helped him run the studio. He most likely began as a portrait photographer who sometime later switched to making erotic studies of undraped figures. His earliest known photographs are of nudes in classical poses which were typical of that era. Over time his compositions became more contemporary. He began to shoot outdoors and created photo-sets that told a simple story, such as a romantic couple cavorting in a park. At first, Biederer signed his photographs. When he began specializing in nudes and more risque subjects, he marked some with his initials J.B. or just a "B" beneath an accent mark, and then stopped signing them altogether. However, many unmarked images can be identified by the frequently used props, set decorations, and theme.
