Polonsky Foundation
Established in London in 1985 by Hansard Global founder Dr. Leonard S. Polonsky, the Polonsky Foundation operates exclusively as a grant-making charity. Its corpus traces directly to Polonsky's financial-services career; the foundation maintains no return-seeking portfolio, instead deploying capital solely through charitable disbursements. Oversight sits with a board of managing trustees led by Dr. Polonsky's son, Marc A. L. Polonsky. Cultural-heritage digitisation forms the foundation's most visible program. It funds large-scale imaging and digital-platform builds at the Bodleian Library, the British Library, and the Bibliothèque nationale de France, among others. Outside of archives, grants extend to humanities research at academic institutions, arts-education initiatives, and the development of new creative work — spanning theatre commissions, musical performance residencies, and fellowships for emerging humanities scholars. The geographic footprint concentrates on UK and continental European beneficiary institutions, with selective deployments in Israel and the United States. Total corpus size and annual disbursement figures are not publicly reported. Physical holdings include a commercial office on Park Crescent in London, a residential property in New York City, and a vacation home in Aspen, Colorado. The Polonsky Academy for Advanced Study operates in Jerusalem. No external investment team, fund-commitment program, or co-investor club is observable from the foundation's public record. March 2025: Founder Leonard S. Polonsky passed away, consolidating stewardship further with Marc Polonsky and the existing trustee board. Unlike perpetual endowment vehicles that balance grant-making against portfolio growth, the Polonsky Foundation's posture is wholly distributional — a structure common among European founder-led philanthropies but distinct from the hybrid investing/grant-making model typical of American foundations. Grant commitments are booked bilaterally with cultural institutions rather than through donor collaboratives, and the foundation does not participate in pooled philanthropic funds. Governance passes along family lines: Marc Polonsky concurrently serves as a director of Hansard Global, maintaining an operational link between the wealth-generating entity and the charitable vehicle it funds.

Frequently asked questions
Who makes grant decisions at the Polonsky Foundation?
Managing Trustee Marc A. L. Polonsky — son of founder Leonard Polonsky — leads the board. Grant decisions are made by the trustees, who evaluate proposals directly against the foundation's three published subject areas: cultural heritage and digitisation, humanities education and research, and arts innovation.
How does the foundation differ from a university endowment or investor foundation?
The Polonsky Foundation is a pure grant-maker. It does not maintain an investment portfolio, allocate to funds, or seek financial returns. All capital flows out as charitable disbursements, placing it in a distinct regulatory and operational category from perpetuity-seeking endowments.
Does the Polonsky Foundation accept unsolicited grant proposals?
The foundation's published materials describe proactive grant-making to named partner institutions — including the Bodleian Library and the Bibliothèque nationale de France — rather than an open RFP process. Unsolicited-proposal posture is not publicly clarified.
What is the foundation's most significant ongoing program?
The digitisation of major library collections represents the most sustained program. Named collaborations include the Polonsky Foundation Digitisation Project, which has funded full manuscript-digitisation pipelines at Oxford's Bodleian Library and the Vatican Library, with partnerships extending to the British Library and the National Library of Israel.
How is the Polonsky Foundation connected to Hansard Global plc?
Dr. Leonard S. Polonsky founded Hansard Global, an Isle of Man-based financial-services firm. His son Marc Polonsky serves as a non-executive director of Hansard while simultaneously acting as Managing Trustee of the foundation, linking the wealth-origin entity and the philanthropic vehicle at the governance level.
