Otto Dix, German Expressionist, painted the dancer Anita Berber, in 1925 (see portrait in red). This image has documented her existence, which few of us today know of, but in her time in Weimar, Berlin, Berber was the essence of decadence, a sometime-prostitute, a cabaret dancer with a famous Sun-worshipping dance, a bisexual, a cocaine addict, and a sometime sex-slave. (See more below)
Berber was used by the Nazis to describe their distaste for Berlin, its immorality, and what they called “the Jewish mindset” since they blamed the rampant prostitution and vice of Weimar, Berlin, on Jews. I haven’t found any data yet proving she was actually Jewish, however, but this never stopped a Nazi.
