“Circle! Square! Progress!: Zurich’s Concrete Avant-garde” is a richly detailed and visually striking publication that explores one of Switzerland’s most influential modern art movements. As the first comprehensive survey of the Zurich Concretists, the book traces the origins and evolution of this avant-garde group rooted in Bauhaus principles and Constructivist thought. It highlights the work and impact of key figures such as Max Bill, Camille Graeser, Verena Loewensberg, and Richard Paul Lohse, placing them within a wider cultural and political context. Through a blend of essays and archival material, the book reveals how their ideas reshaped design, architecture, and visual language. The narrative also examines their struggles against anti-modernist sentiment during the 1930s and 1940s, offering a deeper historical perspective. Lavishly illustrated, it features a wealth of artworks, rare documents, and previously unpublished material. The publication draws connections to broader influences including mathematics, music, and graphic design. It vividly captures the creative energy of Zurich’s artistic scene, from intellectual debates to cultural experimentation. Both informative and visually compelling, it serves as a valuable resource for design enthusiasts and historians alike. This book stands as a definitive tribute to the legacy and innovation of the Zurich Concrete movement.
