Book excerpt: This book chronicles the creative period of the 1950s and 1960s, a high point in American art. In his collaborations with Merce Cunningham and John Cage, and as a pivotal figure linking abstract expressionism and pop art, Robert Rauschenberg was part of a revolution during which artists moved art off the walls of museums and galleries and into the center of the social scene. Rauschenberg's vitally important and productive career spans this revolution, reaching beyond it to the present day. The book features the artists and the art world surrounding Rauschenberg--from Jackson Pollock, and Willem de Kooning to Jasper Johns, Frank Stella, and Andy Warhol, together with dealers Betty Parsons, and Leo Castelli, and the patron Peggy Guggenheim.
