The M66 Foundation concentrates its giving on education, making large, general-support gifts to prominent academic institutions. Its grants favor elite private K–12 and higher education institutions, with repeat multi-year support to a small set of beneficiaries rather than broad grassroots funding. The foundation appears comfortable funding operating/general purposes rather than narrowly restricted programs.
Concentrated, high-dollar grants to a small number of institutions with repeat support to the same grantees; predominately unrestricted/general operating gifts.
The M66 Foundation Inc C/o Jonathan Korngold Director gives at a level that supports major institutional budgets, with a $600,000 grant to Harvard College as the largest recent award in the record. Its giving pattern centers on education and related institutional support, especially to elite private schools and selective universities. The foundation also shows repeat support for the same recipients over multiple years, including Harvard College and The Dalton School, which suggests a concentrated approach rather than a broad, open-ended grant portfolio. The recent record includes a mix of large and mid-sized general grants to prominent academic institutions and a few related civic or cultural organizations. Harvard College received $600,000 in 2024 and another $300,000 in 2025. The Dalton School received $300,000 in 2024 and $100,000 in 2023. Other education-linked awards include University of Florida, University of Pennsylvania, The Rockefeller University, and Dream Charter School East Harlem. The foundation also made general-support grants outside core education, including to Central Park Conservancy, American Museum of Natural History, and Council on Foreign Relations.
Education is the clearest throughline in the recent grants. The foundation gave $600,000 to Harvard College in 2024 and $300,000 in 2025, both listed as general support. The Dalton School also received repeated general grants, including $300,000 in 2024 and $100,000 in 2023. Beyond private-school and undergraduate support, the foundation backed public and research institutions as well. University of Florida received $166,667 in 2025 for general support, while The Rockefeller University received $15,000 in 2023, $10,000 in 2024, and $10,000 in 2025. It also supported Dream Charter School East Harlem with $15,000 in 2023 and Harlem Rbi - Dream Charter School with $10,000 in 2024 and $10,000 in 2025. These awards point to a preference for institutional stability across K–12, higher education, and education-adjacent organizations.
Typical gifts cluster around a $10,000 median, with the lower quartile at $5,000 and the upper quartile at $23,750. The foundation also makes occasional much larger awards, including six-figure grants, which pull the distribution upward. The record shows repeat giving to the same organizations across multiple years, including Harvard College, The Dalton School, Central Park Conservancy, and The Rockefeller University. Grants are listed as general support, indicating unrestricted operating-style funding rather than tightly project-specific awards.
