Overview

The Abner Rosen Foundation was established in 1994 by the late real estate mogul Abner Rosen. Currently managed by his son Jonathan Rosen and daughter-in-law Jeannette Rosen, the foundation maintains a deliberately low public profile. With annual giving that has varied significantly in recent years ($69,301 in 2023, $124,028 in 2022, $116,750 in 2021), the foundation makes grants to carefully selected organisations. The foundation's grantmaking is heavily influenced by the Rosen family's personal collecting interests, particularly Jonathan's expertise as a numismatist and collector of ancient Mesopotamian cylinder seals. This results in focused support for arts and cultural institutions, Jewish causes, and higher education.

Funding Priorities

Grant Programs

The foundation operates a single discretionary grant programme with awards reportedly ranging from $12,500 to $1,000,000 based on secondary sources. The foundation made 9 awards in 2022 and 14 awards in 2021. The foundation makes grants on a trustee-discretion basis rather than through formal application cycles.

Priority Areas

Arts and Culture (Primary Focus)
The foundation prioritises institutions aligned with the Rosen family's collecting interests, particularly in ancient art, numismatics, and classical studies. Past support has included:

• The Metropolitan Museum of Art
• The Pierpont Morgan Library (now The Morgan Library & Museum)
• Central Park Conservancy
• New York University's Institute for the Study of the Ancient World

Jewish Causes and Israel
Strong support for Jewish cultural institutions and Israeli museums, including:

• American Friends of Israel Museum
• American Friends Lands Museum Jerusalem (reported seven-figure gift per secondary sources)

Higher Education
Selective support for university programmes, particularly those focused on ancient world studies and related disciplines, with New York University being a notable recipient.

What They Don't Fund

The foundation does not fund:

• Organisations outside its core interest areas
• General operating requests from organisations without existing relationships
• Individual scholarships or fellowships
• Political or advocacy organisations

Governance and Leadership

The foundation is managed by Jonathan Rosen (son of founder Abner Rosen) and Jeannette Rosen (Jonathan's wife), who serve as trustees. Jonathan Rosen is an accomplished collector with expertise in ancient numismatics and Mesopotamian cylinder seals, which directly influences the foundation's grantmaking priorities. He has been a Fellow of the American Numismatic Society since 1997 and is recognised as one of the foremost collectors of Archaic coinage. Both Jonathan and Jeannette Rosen are known philanthropists with connections to major cultural institutions including Lincoln Centre, the Metropolitan Museum of Art, and the Museum of Fine Arts in Boston.

Application Success Factors

Since the Abner Rosen Foundation operates exclusively through trustee-identified grants, there is no traditional application process. Organisations that receive funding typically:

1. Align with Family Collecting Interests: The foundation's support is heavily influenced by Jonathan Rosen's expertise in ancient numismatics and Mesopotamian artefacts. Institutions with strong programmes in ancient world studies, classical archaeology, or related fields are more likely to be on the foundation's radar.

2. Maintain Existing Relationships: The foundation gives to "preselected charitable organisations," indicating that grants flow to institutions with which the trustees already have connections.

3. Major Cultural Institutions: Past grantees are predominantly well-established cultural institutions in New York, particularly museums and libraries with significant collections in areas of interest to the family.

4. Support Specific Programmes or Collections: Rather than general operating support, grants often support specific initiatives or collections that align with the trustees' scholarly and collecting interests.

5. Jewish and Israeli Cultural Preservation: Organisations focused on Jewish heritage and Israeli museums receive significant support, including substantial seven-figure gifts according to secondary sources.

Key Takeaways for Grant Writers

• No Public Application Process: This foundation cannot be approached through traditional grant proposals; they identify and select grantees independently.
• Family Interests Drive Giving: Jonathan Rosen's expertise in ancient numismatics and Mesopotamian seals is the strongest predictor of funding alignment.
• Relationship-Based Philanthropy: Existing connections to the trustees or their network are essential for consideration.
• Highly Variable Giving: Annual giving has fluctuated significantly in recent years, from under $70,000 to over $120,000.
• New York Focus: While some national organisations receive support, there is a clear preference for New York-based cultural institutions.
• Quality Over Quantity: With 9-14 grants made in recent years, the foundation is highly selective.
• Low Profile Strategy: The absence of a website, application guidelines, or public communications suggests the family prefers quiet, strategic philanthropy.
