Bernard Ratzer

Bernard Ratzer was a British cartographer, best known for his 18th-century maps of early New York City. Today, his name is invoked as something of a Da Vinci of New York cartography, as his best known work was the 1770 "Plan of the City of New York".

A librarian at Harvard University discovered a 1769 Ratzer map showing the disputed border between New York and New Jersey. The Harvard libraries made this map publicly available in early 2016.
