Jacques Cortelyou

Cortelyou's map of New Amsterdam (the Castello Plan).

Jacques Cortelyou (c. 1625–1693) was an influential early citizen of New Amsterdam (later New York City) who was Surveyor General of the early Dutch colony. Cortelyou's main accomplishment was the so-called Cortelyou Survey, the first map of New York City, commonly called the Castello Plan after the location in a Tuscan palace where it was rediscovered centuries later.
