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". One of his earliest drafts of the "Plan of the City of New York," which shows in great detail many of the time's most famous landmarks in addition to a small illustration of Manhattan as seen from Governor's Island, was given to George III, England's king, as a gesture from the publishers.
