One of the most innovative artists and designers of the 20th-century avant-garde, Sophie Taeuber-Arp (Swiss, 1889-1943) challenged the borders between abstract art, design and craft. Tate Modern’s major exhibition, which opens on July 15 and closes October 17, will be the first in the U.K .to trace Taeuber-Arp’s career as a painter, architect, teacher, writer, and designer of textiles, marionettes and interiors. Bringing together more than 200 objects from collections across Europe and America, the exhibition will show how she blazed a new path for the development of abstraction.
