Part-time Palm Beach resident Ken Griffin has made one of the largest contributions to the Museum of Modern Art in the history of the institution.

The founder and CEO of Citadel donated $40 million to MoMA, and the generous contribution is unrestricted meaning the museum can use the funds however it sees fit.

To memorialize Griffin’s generosity, MoMA’s cube-like structure will be names the Kenneth C. Griffin Building.

Griffin’s generosity is well known. In 2014, he made a $150 million gift to his alma mater Harvard, which at the time was the largest private contribution in the history of the school.

Back in his undergraduate days, Griffin began trading from his dorm room at Harvard using a fax machine. From those humble beginnings, he founded alternative asset manager Citadel in 1990. Citadel Group now includes Citadel Securities and Citadel Technology.
