Top Museum Donors in Philadelphia: Who Supports the Arts

· 9 MIN READ · TOP MUSEUM DONORS

Philadelphia has a deep cultural infrastructure built on sustained private giving. The Philadelphia Museum of Art, Barnes Foundation, Academy of Natural Sciences of Drexel University, Penn Museum, and National Constitution Center all depend on a core group of donors who show up year after year. The city also has strong representation from community foundations and family foundations with long histories in the region. The PatronView database tracks gift acknowledgments across these institutions and more, covering everything from major art museums to natural history collections.

Rankings reflect the number of individual gift acknowledgments in the PatronView database. Contribution count captures breadth of giving history, not a single cumulative dollar total. For more information about our data collection and methodology, see Data Sources here.
