He spent more than three decades compiling a vast collection of postwar art that included paintings, drawings and sculpture by Andy Warhol, Roy Lichtenstein, Lucian Freud and Jasper Johns, among others. He developed close relationships with some of his favorite artists, like Brice Marden, Ed Ruscha and Mark Grotjahn.
As a supporter of art in the workplace, Mr. Marron lined the walls of UBS PaineWebber’s offices nationwide with works from his collection.
“We all spend probably a third of our lives in our offices,” Mr. Marron told The New York Times in 2005. “Therefore, if you can expose us to another aspect of creativity in our time, it’s a good thing, particularly in the securities business.”
Mr. Marron donated part of the UBS-owned collection — which was valued at about $15 million — to the Museum of Modern Art, where it was exhibited in 2005.
As the art market exploded in recent years, attracting dabblers and speculators, Mr. Marron remained an old-fashioned collector — passionate about the art itself, rather than looking to flip it for a profit.
He recently opened his own private gallery in Midtown Manhattan, which he filled with works from his own collection. He had no interest in making it public, however, preferring to enjoy the art on his own or with friends.
Donald Baird Marron was born on July 21, 1934, in Goshen, N.Y., the son of Edward J. Marron, a writer, and Ethel Baird Marron, a homemaker. He grew up in New York City.
