Cologne artist Hans Salentin (1925-2009) was one of the most versatile German sculptors, especially from the 1960s to the 1980s. He first gained notoriety as an early member of the ZERO group. Salentin, who studied at the Düsseldorf Art Academy in a class with Heinz Mack and Otto Piene, began creating reliefs from roof tiles and aluminum sheets in 1960, which he continues to exhibit at major ZERO exhibitions. Despite his success, from the mid-1960s onward he turned to all-view sculptures made of cast aluminum, which he assembled based on objet trouvé and objet corrigé, recapitulating the contemporary isms. This resulted in contributions to Hard Edge and Pop Art, as well as Realism. His contributions to utopian design, which particularly encompassed vehicles and chairs, led to his participation in documenta 6 in Kassel in 1977. The monograph, published on the occasion of his 100th birthday, comprehensively presents his plastic and sculptural work from its beginnings. For the first time, it also includes the late abstract cardboard sculptures that Salentin created around 2000—after about two decades of turning to collage, drawing, and painting.
