Born in Ukraine and raised by a wealthy uncle in St. Petersburg, Delaunay studied painting in Germany and Paris but is best known for her fashion and textile designs. This portfolio of her work was published in conjunction with her display at the 1925 Exposition des Arts Décoratifs in Paris. Delaunay made no distinction between the fine and decorative arts, transferring to everyday, functional objects the principles of simultanéité, the iconographic theory and technique that she developed with her husband, Robert Delaunay. Simultanéité used color contrasts to create the illusion of depth, movement, and perspective. The Delaunays were frequent collaborators with the artists of the Dada movement; Sonia designed "poem dresses" for the poet Tristan Tzara, for example, and this portfolio features poems by Tzara and others, responding to her designs.
