William Penn Foundation

Otto and Phoebe Haas established the William Penn Foundation in 1945. Their descendants continue to occupy key board seats, including Katherine H. Christiano as current Board Chair and several other family members in governance roles. The foundation remains headquartered in Philadelphia and directs nearly all activity toward the surrounding region. The foundation allocates 34 percent of assets to private equity funds and maintains holdings in hedge funds, real asset vehicles, and U.S. government securities. It participates in both fund commitments and direct program-related investments. All capital deployment stays within North America, with the large majority inside the Greater Philadelphia region. The organization employs 46 professionals and retains Commonfund as outsourced investment advisor alongside several other managers. It maintains membership in the Philanthropy Network Greater Philadelphia. In January 2024 the foundation participated as a speaker at the Leading Philanthropy Conference on regional grantmaking strategies. Governance rests with a board composed of Haas family members across multiple generations. This structure keeps investment policy and grant decisions inside a single family-controlled entity rather than delegating to an external multi-family platform or commercial asset manager.
