notorious

Anita Berber was a weimar-period caberet dancer, among many other things. She is the subject of this painting by Otto Dix, was probably the first person to dance naked onstage and is widely considered to be an important predecessor of modern performance art. You should read this article to learn more. Also of interest is this film, Anita - Tänze des Lasters, which is about a woman who "goes insane, believing herself to be the notorious Anita Berber, a nude art dancer/drug addict/scandalous figure of post-WWI Berlin."

It all sounds VERY interesting. Oh, and you can see some archival footage of her on this (German) news story.
