Czech photographer Jacques Biederer began his Parisian career in 1913 with G-rated portraiture, but soon moved on to more prurient subject matter—though this was still fairly “conventional” sexy materials for the day—ladies in their underwear, really. Then Biederer went through a period of full-on classical nudes, sometimes with couples, sometimes shot “on location,” outdoors or on a carefully arranged set. Then he got into fetish photography—whips, domination, corseting, pony play—pretty scandalous stuff, but always shot with an artistic eye. Biederer was a forerunner of someone like Irving Klaw in the US.
