Overview

The Della Pietra Foundation (EIN: 83-2596679) is a private independent foundation established in 2019 by Vincent Della Pietra and Barbara Amonson. With total assets of $58.7 million and annual giving of approximately $4.6 million, per 2023 990-PF, the foundation focuses on advancing STEM education, mathematical sciences, biomedical research, and scientific discovery. Vincent and his twin brother Stephen Della Pietra are physicists who earned degrees from Princeton and Harvard before working at IBM and later Renaissance Technologies, where they manage research groups. Their philanthropic approach reflects their scientific backgrounds and commitment to public education, particularly supporting programmes that inspire the next generation of mathematicians, physicists, and scientists. The foundation has been a major supporter of Stony Brook University, with the Della Pietra family investing over $10 million across campus programmes.

Funding Priorities

Grant Programmes

The foundation does not operate formal grant programmes with published guidelines. Instead, grants are awarded at the discretion of the trustees to organisations aligned with their interests. Notable funding areas include:

Higher Education - STEM Focus: Major multi-million dollar grants to universities for mathematics, physics, and geometry programmes

• Princeton University (listed as grantee)
• Stony Brook University (multiple programmes)

Youth STEM Education: Support for gifted student programmes in mathematics and science

• Applied mathematics programmes for high school students
• Saturday enrichment programmes

Biomedical Research: Endowed chairs and research initiatives

• Biomedical imaging research
• Global health initiatives

Scientific Communication: Public lecture series and science outreach

• Della Pietra Lecture Series at Simons Center for Geometry and Physics

Priority Areas

Based on documented grants, the foundation prioritises:

• Mathematics Education: Applied mathematics programmes, particularly for gifted high school students
• Theoretical Physics: Geometry and physics research centres
• Biomedical Sciences: Medical imaging and paediatric health research
• Public Science Education: Lecture series and outreach programmes that make advanced science accessible to students and the public
• Global Health: International health research initiatives
• Arts and Culture: Limited support for university arts programmes

What They Don't Fund

The foundation has not publicly listed exclusions, but their documented giving patterns show:

• Focus exclusively on education, science, and research
• No evidence of funding for social services, direct service programmes, or operating support for community organisations
• Grants appear concentrated on institutions rather than individual projects or grassroots organisations

Governance and Leadership

Vincent Della Pietra (Secretary): Twin brother of Stephen Della Pietra. Earned undergraduate degree in physics from Princeton and doctorate in physics from Harvard. Conducted postdoctoral research at the Institute for Advanced Study before working at IBM on statistical pattern recognition. Currently co-manages the General Research Group at Renaissance Technologies. String theorist with deep expertise in mathematical physics and statistical methods.

Barbara Amonson (President): Wife of Vincent Della Pietra. Active in philanthropic leadership alongside her husband, particularly in supporting STEM education and scientific research.

Philanthropic Philosophy

Vincent and Stephen Della Pietra have articulated clear values in their giving:

On Public Universities: Stephen stated, "We chose to create the program at Stony Brook because we believe in the power of the public university to reach more students and inspire the next generation of great mathematicians." This reflects their commitment to maximising educational impact through public institutions.

On Stony Brook's Role: Stephen noted, "Stony Brook has proven to be the intellectual center of Long Island," explaining their sustained investment in the institution.

On Science Communication: The brothers started the Della Pietra Lecture Series "as means to bring greater awareness of recent and impactful discoveries in Physics and Mathematics to the Long Island community, in particular to high school, undergraduate and graduate students with an interest in the sciences."

Their giving is motivated by personal experience with mathematics education during their own high school years and concern about low STEM participation rates among college graduates.

Application Process & Timeline

How to Apply

This foundation does not have a public application process. The Della Pietra Foundation makes contributions exclusively to preselected charitable organisations and does not accept unsolicited requests for funds. This is characteristic of private family foundations where grants are awarded through trustee discretion rather than competitive application processes.

Grants appear to be initiated through:

• Existing relationships with institutions (particularly Stony Brook University)
• Direct trustee identification of organisations and programmes aligned with foundation priorities
• Networks within the scientific and academic communities

Getting on Their Radar

The foundation's giving is highly concentrated on institutions where the Della Pietra family has established relationships, particularly Stony Brook University and Princeton University. Their documented giving shows:

• Long-term institutional relationships: Multiple grants over several years to the same institutions, particularly Stony Brook
• Scientific community connections: Both Vincent and Stephen are active in mathematical and physics research communities through their work at Renaissance Technologies and relationships with institutions like the Institute for Advanced Study
• Geographic concentration: Strong focus on Long Island institutions

Organisations seeking funding would likely need:

• Established credibility in STEM education or research
• Connection to individuals or institutions in the Della Pietra family's professional or philanthropic network
• Programmes aligned with mathematical sciences, physics, or biomedical research

Application Success Factors

Since the foundation operates on an invitation-only basis, traditional application success factors do not apply. However, their documented giving patterns reveal what attracts their support:

Alignment with Trustee Interests

Mathematics and Theoretical Physics: The foundation strongly favours programmes in these fields, reflecting the trustees' professional backgrounds. The Simons Center for Geometry and Physics received $5 million, demonstrating their commitment to advancing these disciplines.

Youth STEM Development: The $500,000 gift for the Della Pietra Family Applied Mathematics Program shows prioritisation of programmes that identify and nurture mathematical talent in high school students. Programmes offering advanced mathematical training to gifted students align with their concerns about low STEM participation rates.

Public Science Education: The establishment and ongoing support of the Della Pietra Lecture Series demonstrates their value for making advanced science accessible. Programmes with three-tier approaches (technical, student-focused, and public) match their model.

Institutional Characteristics

Public Universities: Stephen's explicit statement about "the power of the public university to reach more students" indicates preference for public institutions over private ones, despite their own Ivy League backgrounds.

Research Excellence: Support for centres like the Simons Center for Geometry and Physics shows they fund institutions at the forefront of their fields.

Long Island Connection: Stony Brook's status as "the intellectual center of Long Island" matters to them, suggesting regional impact is a consideration.

Programme Design Elements

Matching Grant Opportunities: Their $1.5 million biomedical imaging gift was matched by the Simons Foundation for $3 million total impact, suggesting they appreciate leverage opportunities.

Named Recognition: Multiple named programmes and spaces (Della Pietra Chair, Della Pietra Lecture Series, Della Pietra Family Auditorium, Della Pietra Family Applied Mathematics Program) indicate they value recognition.

Multi-Level Impact: Programmes serving multiple audiences (high school students, undergraduates, graduate students, faculty, public) align with their documented interests.

Key Takeaways for Grant Writers

• Invitation-only model: This foundation cannot be approached through traditional grant applications; focus on building relationships within scientific and academic networks where trustees are active
• STEM focus is absolute: 100% of documented grants support mathematics, physics, biomedical science, or STEM education—no evidence of funding outside these areas
• Public university preference: Despite Ivy League backgrounds, trustees explicitly value public universities' ability to "reach more students"
