This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.

Key takeaways

  • The foundation does not accept unsolicited requests and says its grants go to preselected organisations, so a cold application is not the route to take.
  • Its filing describes its grants as general support across museums, hospitals, colleges, libraries, policy, environmental and community bodies, so check your work against those kinds of recipients.
  • About 8 in 10 of its grants fall between $5,000 and $2,500,000, and half are $100,000 or less, so a modest request sits well within the usual range, although its largest grant was $13,500,000.
  • Two-thirds of its grant dollars went to organisations it had funded in earlier filings, so repeat relationships matter.
  • No geographic focus is stated, and its grants are concentrated in New York, Massachusetts and District of Columbia, but that is a pattern in its grants and not a rule about who may apply.

Overview

Sue & Edgar Wachenheim Foundation is a US private foundation based in Purchase, NY.

What they fund

Profile based on the foundation's IRS Form 990-PF filings (TY2024, TY2023, TY2022) only: no website or other web source for the foundation was found. Every statement is checked against the filings. Sources read on 12 October 2026.

Priority Areas

The foundation’s filings describe its grants as general support rather than naming a particular funding field. Its recorded grants went to museums and other cultural institutions, hospitals, colleges and schools, libraries, policy and international-affairs organisations, environmental organisations, and community and social-service bodies. The recipient list includes institutions and organisations in several states; the grant record is especially concentrated in New York, with additional recipients in Massachusetts and the District of Columbia. The filing also indicates that grants go to preselected charitable organisations, rather than through an unsolicited application process.

Geographic Focus

No geographic focus is stated; the filings show grants mainly in New York, Massachusetts and District of Columbia.
