In 1969, Gerry Schum, the German video and broadcast pioneer, presented over Berlin television a video program entitled “In Land Art,” which he had made with Marinus Boezem, Jan Dibbets, Barry Flanagan, Richard Long, Walter De Maria, Dennis Oppenheim, Robert Smithson and Michael Heizer. The following year, Schum broadcast “Identifications,” another co-production he had made with Joseph Beuys, Daniel Buren, Gilbert and George and Mario Merz among others. These two programs comprise the bulk of Schum’s retrospective, which was organized by Dori ne Mignot of the Stedelijk Museum, Amsterdam.
