Peter Grubb was a Pennsylvania iron industry pioneer who founded the Grubb Family Iron Dynasty when he discovered Cornwall Iron Banks in 1737, still the largest domestic iron ore deposit east of Lake Superior. He founded Cornwall, Pennsylvania, and became an ironmaster as he mined the ore and built the historic Cornwall Iron Furnace. He named them after Cornwall, UK, the birthplace of his father John Grubb.

Peter leased the operation for 20 years and retired to Wilmington, where he bought and sold real estate. Later, Cornwall Iron Works was an important contributor to the Revolution under the ownership of his sons Curtis and Peter Jr., the latter's descendants went on to become one of Pennsylvania's most prominent iron producers well into the late 1800's.

Peter first married Martha Bates Wall, widow of James Wall, at Caln Meeting in 1732. They had two sons, Curtis and Peter Jr. After her death when Peter Jr. was an infant, he wed Hannah Mendenhall Marshall, the widow of Thomas Marshall, at Concord Meeting in 1741. They had no children.
