## About

John F. and Josephine Connelly established the Connelly Foundation in 1955. The couple built the endowment from proceeds of Crown Cork & Seal, the packaging manufacturer John Connelly led. Josephine C. Mandeville, their daughter, later served as Chair Emerita. The foundation allocates across private equity, venture capital, and real-estate secondaries. Confirmed holdings include Makena Perpetual Private Equity Fund, TIFF Keystone Fund, Fir Tree International Value Fund II and Whitehall Street Real Estate L.P. XI, and Shift Neighborhood Fund. Geographic exposure centers on the United States with additional global fund exposure. A public equity legacy stake remains in Crown Holdings Inc. Fourteen professionals operate from the West Conshohocken headquarters. The foundation belongs to the Philanthropy Network Greater Philadelphia, Council on Foundations, PEAK Grantmaking, and Exponent Philanthropy. In December 2024 it sponsored the Neumann Scholars Virtual Ceremony recognizing Catholic-school academic achievement. Governance separates the primary foundation from three adjacent family vehicles: the Connelly Family Foundation, Chuck Connelly Foundation, and Marilyn & John Connelly Charitable Fund. Investment advice is provided by SEI Private Trust Company and Glenmede, with Grant Thornton as auditor and Blank Rome as counsel.
