An absorbing study of Swiss artist Sophie Taeuber-Arp’s influential work, focusing on the formal logic that drove her innovative creative production. Edited and with text by Briony Fer, Sophie Taeuber-Arp: The Rule of Curves examines the work of leading twentieth-century artist Sophie Taeuber-Arp (1889–1943), whose pioneering, multifaceted work challenged traditional hierarchies, reconciled extremes, and asserted art’s urgent relevance to daily life. This bilingual, clothbound volume focuses on the formal logic that drove her bold and wide-ranging creative production while revealing how moving and working between mediums simultaneously expanded and crystallized her aesthetic. Alongside Fer’s discerning insights into Taeuber-Arp’s work, an essay by Jenny Nachtigall explores the artist’s bold engagement with the intellectual context of international modernism through a discussion of Taeuber-Arp’s relationship with Vitalism.
