History

Tinicum Marsh

Back when William Penn arrived, the Tinicum Marsh covered more than 5,700 acres along the Delaware River. For centuries, Native Americans and early European settlers drew food and resources from its waters and plants.

Everything changed with industrialization. Airport construction and urban expansion chipped away at the marsh. By mid-twentieth century, it had shrunk to a tiny fraction of what it once was. But locals fought to save what remained.

Refuge Establishment

Congress established the refuge in 1972 as the nation's first urban wildlife refuge. A decade later, in 1991, it was renamed to honor Senator John Heinz of Pennsylvania. He'd been a fierce environmental advocate until his death in a plane crash that same year.
