It has been a little over one year since Agnes Gund sold Roy Lichtenstein’s 1962 work Masterpiece for $165m to launch the Art for Justice Fund with the aim of reforming the US prison system. The fund has already awarded $22m in grants to 30 organizations, with another round due to be announced later this spring.

“I didn’t used to sell anything, but then I was interested in doing philanthropic things,” Gund told us in a recent interview. When Gund bought her first major piece after her father died in 1966—a Henry Moore from New York dealer Sidney Janis—she says she “started to have nightmares about it because I thought, ‘How could I be spending this money?’ And that was when I decided that I would give works of art to different museums. So, it was sort of to assuage the guilt of buying something that at the time was very expensive, but which now seems like nothing, because the prices have skyrocketed.”

As her involvement in social causes grew, she would “ask to do something and then think, ‘Oh my gosh, how am I going to pay for it?’” Fortunately, she is not undertaking this current endeavor alone. Other collectors, including Jo Carole Lauder, Daniel Loeb and Donald Marron, have followed Gund’s example and sold works or made cash donations to the Art for Justice Fund, with the goal of matching her $100m seed gift.
