This monograph surveys the diverse oeuvre of the ever-popular German artist Imi Knoebel, whose adventures in the elementary functions of form and color seem more relevant than ever. Opening up new perspectives on selected phases of Knoebel's career, and tackling many lesser-known explorations alongside his classic geometric/minimalistic fiberboard paintings, it examines, in chronological order, the artist's time at the Darmstadt Werkkunstschule and the Dusseldorf Art Academy, where he studied with Joseph Beuys, and where he met one of the artists with whom he would become most closely associated, Blinky Palermo. Also addressed here is Knoebel's relationship to American Minimalism, and his early explorations of serial light photography and printmaking. This volume focuses on these early activities and recent paintings from the 1990s to 2009.
