Jasper Johns
While at PaineWebber, Marron personally directed the firm's acquisition of more than 850 post-1945 works by major American and European artists -- including Jasper Johns, Roy Lichtenstein, Willem de Kooning, and Susan Rothenberg, among many others -- to create the PaineWebber Collection. In 2002, UBS PaineWebber promised MoMA 37 works, including paintings, drawings and sculpture by Andy Warhol (including "Cagney", 1962), Roy Lichtenstein, Lucian Freud, and Jasper Johns. The donation was to be made over 15 years and was completed in 2017.
