Within chronological themed chapters, this book highlights Sonia Delaunay's (1885-1979) unique contribution to 20th-century art as an artist who successfully bridged the fine and decorative arts, moving freely between the two. A successful fashion designer in the 1920s and a pioneer in abstract painting, along with her husband Robert, Sonia Delaunay is a landmark figure in 20th-century visual art who consciously applied the fine art idea to fashion and other aspects of design. Delaunay operated at a time when the artistic concerns of her avant-garde contemporaries were confined to the sphere of "High Art", e.g., experimenting with Cubist or Futurist ideas. Today, an increasing number of artists and designers are working across disciplines, breaking down the barriers between art and design. A prime force of such movement, Delaunay's work is of great relevance to our times.
