Book excerpt: Women of the Avant-Garde 1920-1940 presents eight female artists who made major contributions to Dada, Surrealism, Constructivism and other European avant-gardes of the modernist era: Claude Cahun, Sonia Delaunay, Germaine Dulac, Florence Henri, Hannah Höch, Katarzyna Kobro, Dora Maar and Sophie Taeuber-Arp. The artists are constellated in relation to one another across five themed sections that illuminate the nature of their respective innovations: "Composing Color," "Constructing Space," "Different Rules," "New Identities" and "Another Reality."
