Fritza Riedler is one of the early portraits of Gustav Klimt. Society underwent dramatic changes at the turn of the century. Klimt's portraits of females give an indication of the emergence of an increasingly confident middle class. His 1898 portrait of Sonja Knips elevated him to the role of portraitist of a well-heeled Viennese bourgeoisie. His likenesses of Fritza Riedler and Adele Bloch-Bauer (one of the most expensive paintings in the world) have lost nothing of their appeal to this day. Likewise that of his companion until the end of his life, Emilie Flöge, who was an emancipated and modern woman.
