Exploring the decades-long working relationship between Fred Sandback and Dia Art Foundation, which served as a venue for his "situational" sculpture

In 1968, sculptor Fred Sandback (1943-2003) mounted his first solo exhibition at Heiner Friedrich's Munich gallery, displaying works made from elastic cord or acrylic yarn that traced planes and volumes in space. Thus began a long-term relationship that extended to Dia Art Foundation, the institution cofounded by Friedrich in 1974. Until now, there has been little published on Sandback's extraordinary alliance with Dia. Essayists Julian M. Rose, Corinna Thierolf and Edward A. Vazquez, as well as conversation partners Matilde Guidelli-Guidi and Curtis Harvey, unearth and explore archival documents, sketches and photographs to reveal how the institution offered Sandback both space and time to meticulously hone his sculptural interventions in the architectural environments of Dia, including the Fred Sandback Museum in Winchendon, Massachusetts, and Dia Beacon, New York.
