Casimir Theodor Goerck (c. 1755 - November 19 or December 11, 1798) was one of the few people officially recognized as 'city surveyor' for New York City. Of Polish or German origin, Goerck came to America to serve as an artillery officer in the Continental Army during the American Revolution. Per The Iconography of Manhattan Island, Goerck first arrived on the scene in New York City in 1785. New York City hired Goerck that year to survey the city's 'Common Lands'. The Bayard family, relatives of Peter Stuyvesant, hired Goerck in 1788 to survey the part of their estate that was west of Broadway so that the land could be sold in lots. This survey resulted in the implementation of one of the first attempts to apply a grid to Manhattan Island. Mercer, Greene, Wooster, and other streets that are now at the core of Soho were laid down here. Goerck was asked once again in 1794 by the Common Council to resurvey the 'Common Lands' in an effort to make the lots more rectangular and regular. He also was tasked with adding roads, all in an effort to help facilitate the sale of the 'Common Lands'. After two years, Goerck completed this second survey in 1796. Goerck was commissioned by the Common Council yet again in 1797 to prepare a map of the city as it existed with the help of French architect Joseph-Fran├žois Mangin. Unfortunately, Goerck died of yellow fever before this map was finished.
