Countess Fanny "Franziska" zu Reventlow (Fanny Liane Wilhelmine Sophie Auguste Adrienne) 18 May 1871 – 26 July 1918) was a German writer, artist and translator, who became famous as the "Bohemian Countess" of Schwabing (an entertainment district in Munich) in the years leading up to World War I.
While many of her peers were pressing for improved social, political, and economic rights for women, Reventlow argued that ardent feminists, whom she labelled "viragos," were actually harming women by attempting to erase or deny the natural differences between men and women. Reventlow maintained that sexual freedom, and the abolition of the institution of marriage, were the best means by which women could hope to achieve a more equal social standing with men. via Wikipedia
