William Penn Foundation

• 1. Introduction

  ›

  The William Penn Foundation began not with that name, but with a wife's. When Otto Haas and his wife Phoebe established their grant-making organization in Philadelphia in 1945, they called it the Phoebe Waterman Foundation. Otto Haas was a businessman, and the couple wanted their resources to do something lasting for the city they called home. That founding name, now largely forgotten, hints at a quieter story behind one of Philadelphia's most significant philanthropic institutions. What did the foundation eventually become? What does it fund, and how much has it grown? And what does the scale of its giving reveal about the needs of the Greater Philadelphia region?

• 2. From Phoebe to Penn

  ›

  Philadelphia in 1945 was a city rebuilding its identity after the strains of wartime. Otto Haas chose that moment to formalize his family's charitable intentions in the form of a named foundation. The original name honored his wife Phoebe directly, placing her at the center of the institution's identity from the start. At some point the organization took on a new name: the William Penn Foundation, invoking the founder of Pennsylvania himself. That shift connected the foundation's work to a much older civic inheritance, one rooted in the ideals Penn brought to the region in the late seventeenth century. The name change signaled ambitions that reached beyond a single family's legacy and toward the broader story of the city.

• 3. What the Foundation Funds

  ›

  The foundation's stated mission describes three distinct goals: fostering rich cultural expression, strengthening children's futures, and deepening connections to nature and community. Those goals translate into grants across education, arts, and the environment. Taken together, they suggest a theory of what a city needs to thrive: not just economic output, but creative vitality, the preparation of its youngest residents, and access to the natural world. The foundation directs all of this toward what it calls the Greater Philadelphia region, a geographic frame that extends its reach beyond the city limits. Recipient charities working in any of these three areas have made the foundation a consistent presence in the civic life of the region for decades.

• 4. The Scale of Giving

  ›

  In 2008, the foundation disbursed new and continuing grants worth just under $63 million. By 2021, that annual total had grown to more than $183 million. The difference between those two figures, spread across thirteen years, reflects both the foundation's expanding resources and a deepening appetite to deploy them. A grant-maker disbursing that level of funding each year becomes a structural force in the nonprofit landscape it serves. Organizations in education, the arts, and environmental work in the Philadelphia region plan around the foundation's cycles, compete for its attention, and in many cases depend on its continued support to sustain programs that serve thousands of residents.
