The Abner Rosen Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The Abner Rosen Foundation states that it does not accept unsolicited requests and works by invitation only, so a cold application is not the route in; groups without a way to be invited should not send one.
- The filing shows a mixed portfolio of charitable organisations with no stated funding field, so check closely whether your work plainly matches before you seek an introduction.
- A modest request fits best: a typical grant band of $1,000 to $70,000 holds about 8 in 10 of its 25 grants, and half were $9,000 or less, though its largest grant was about $200,000, so that band is not a ceiling.
- Repeat support is part of its giving, since 23% of its grant dollars to organisations went to groups it had also funded in its earlier filings, so any existing connection is worth noting.
Overview
The Abner Rosen Foundation is a US private foundation based in New York, 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 7 October 2026.
Priority Areas
The filings do not name a specific funding field. Grants went to a varied group of charitable organisations, including a medical charity focused on bone marrow and cancer, an ornithology organisation, a school, an opera company, museums, an animal-welfare organisation, a neighbourhood organisation, a synagogue, a children’s organisation and an arts-research body. The stated purpose for every grant is only that it furthers the recipient’s exempt purpose; the filings do not identify a common programme or explain selection criteria. They therefore show a mixed charitable portfolio rather than a stated thematic strategy.
Geographic Focus
No geographic focus is stated; the filings show grants mainly in New York.
How to apply
