On Kawara
Since the early 1960s he and his wife, Carol Androccio, gathered nearly 9,000 works of art through purchases, in trades with other artists and dealers, or as gifts. In this way he acquired works by approximately 750 artists, including Flavin, Ryman, Hanne Darboven, Eva Hesse, Donald Judd, On Kawara, Carl Andre, Dan Graham, Hans Haacke, Gerhard Richter, and others. In 2007, the exhibition "Selections from The LeWitt Collection" at the Weatherspoon Art Museum assembled approximately 100 paintings, sculptures, drawings, prints, and photographs, among them works by Andre, Alice Aycock, Bernd and Hilla Becher, Jan Dibbets, Jackie Ferrara, Gilbert and George, Alex Katz, Robert Mangold, Brice Marden, Mario Merz, Shirin Neshat, Pat Steir, and many other artists.
