Joseph Beuys spent his entire life dying, his widow once said. In January 1986, his heart did in fact stop beating. Urns with his ashes were committed to the depths of the North Sea. Since then, he has been regularly resurrected -- as a myth, a heroic figure, a saint of contemporary art history and an innovator, even on the political scene. During the nearly 30 years since his death, he has become larger than life and, ultimately, sacrosanct: a German icon.
