## About

Stony Brook Foundation was established in 1965 as a private non-profit corporation. It functions as the primary vehicle for private fundraising and asset management on behalf of Stony Brook University. James H. Simons served as Chair Emeritus until his death in 2024 and directed major gifts including a $500 million unrestricted donation from the Simons Foundation in 2023. The foundation allocates across public equities, fixed income, private equity, and real assets. Confirmed holdings include the Pollock-Krasner House and Study Center and the Southampton Campus. It participates in joint ventures such as the New York Climate Exchange on Governors Island. Geographic focus remains concentrated in New York State with additional land holdings in Alabama. The organization maintains 23.7 percent in private equity. It employs external advisors including TIFF Advisory Services, PNC Institutional Asset Management, and Grant Thornton. A recent operational event occurred in April 2024 when the foundation sponsored the Stars of Stony Brook Gala. The board includes trustees with ties to Renaissance Technologies and Euclidean Capital. Governance centers on a volunteer board of trustees that oversees both investment policy and real estate subsidiaries. Stony Brook Foundation Realty Inc. holds and develops university-adjacent properties under direct ownership structures. This architecture separates philanthropic receipt from operational asset management.
