George Heap (1715 - 1752) was a Pennsylvania landholder and county Coroner, who was additionally an assistant surveyor-general for the province, a mapmaker, and mapseller. He is most noted for his drawing the most important early view of Philadelphia - The East Prospect of the City of Philadelphia - as well as his Map of Philadelphia and Parts Adjacent with Perspective View of the State House, 1750 The Prospect was, apparently, the death of him: He finished drawing the view in September 1752 and set out in early December of that year for England in order to have it engraved. His voyage had not exited the Delaware before he 'was seized with a pain in his head and died'. He was buried at Christ Church, Philadelphia.
