Summary
Bill Ackman, the billionaire founder and CEO of Pershing Square Capital Management, and architect Neri Oxman have committed $25 million to the Center for Jewish History as a landmark challenge grant announced in December 2025. The pledge is structured as a matching endowment commitment: if the Center raises an additional $25 million, Ackman and Oxman's $25 million gift will be matched, anchoring the institution's broader $100 million endowment capital campaign. This represents the single largest commitment in the Center's 25-year operating history.
The financial structure demonstrates sophisticated philanthropic engineering. Ackman and Oxman have agreed to manage the endowment fund through an investment entity operated by Pershing Square at no management fee, with a distribution rate of 5% of the fund principal paid annually to the Center. This arrangement ensures predictable, sustainable funding while leveraging Pershing Square's investment expertise to optimize long-term capital growth—a model increasingly favored by family offices and institutional donors seeking tax efficiency and professional stewardship.
Ackman's involvement with the Center reflects a decades-long family commitment to Jewish history preservation. The Ackman family established the Ackman and Ziff Family Genealogy Institute in 2007, creating the nation's first permanent Jewish genealogy center open to the public. This initiative was inspired by Larry Ackman's personal devotion to documenting and remembering family ancestry. Ackman himself served as Board Chair from 2011 to 2014, during which period he played a critical role in eliminating accumulated institutional debt and establishing the financial foundation necessary for long-term organizational stability.
According to Dr. Gavriel Rosenfeld, President of the Center for Jewish History, the timing of the gift carries particular resonance, arriving "at a moment of both urgency and hope" and acknowledging Ackman and Oxman as "stalwart guardians" of the institution. The challenge grant structure incentivizes broader donor engagement and provides institutional leadership with a concrete, achievable intermediate milestone toward the larger endowment goal—a best-practice mechanism common in major institutional capital campaigns.
