- This series of field sketches and finished maps of projected battle sites in New York, New Jersey, Connecticut and Pennsylvania during the Revolutionary war was begun by Robert Erskine, geographer and surveyor-general to the Continental Army, and completed by his successor, Simeon De Witt. Robert Erskine (1735-1780) was appointed Geographer to Washington’s army in 1777. He surveyed both sides of the Hudson River and a large area covering the adjoining states. Many of the maps are rough field sketches, from which more detailed maps were later drawn. Simeon DeWitt (1756-1834) succeeded Erskine as Geographer-in-Chief in 1780, and oversaw surveys of the roads heading south through Maryland and Virginia to Williamsburg and Yorktown, aiding in Washington’s decisive victory at Yorktown. The Erskine-De Witt series culminates with the detailed Winter-Cantonment of the American Army and it's [sic] Vicinity for 1783, which shows the final encampment of the Continental forces at New Windsor, New York, during the winter of 1782-1783., New-York Historical Society
- These 89 maps, hand-drawn and hand-colored, were created in 1899 under the leadership of Lawrence Veiller in conjunction with the Charity Organization Society of New York for display at the Tenement House Exhibition, held in Manhattan in February 1900. They depict neighborhoods throughout Manhattan, from the Battery to Harlem, in two series: “Strong-holds of poverty” and “Prevalence of disease.” Colored dots on the first series indicate the number of families requesting charitable assistance. On the second series, the dots represent instances of tuberculosis, typhoid fever, scarlet fever, and diphtheria. On both series, the population of each block is stamped at its center. The maps were donated to the New-York Historical Society by Lawrence Veiller in 1920.
- These highlights from the Patricia D. Klingenstein Library’s extensive map collection illuminate the tremendous geographic, political, and economic changes that transformed thirteen distinct colonies in North America into a new nation. Included are maps produced by Francis Maerschalck and Bernard Ratzer before the Revolutionary war; surveys by George Washington’s cartographers, Robert Erskine and Simeon DeWitt, and other maps that document military situations during the war; and maps instrumental in identifying and celebrating the new nation, like John Jay’s red-lined copy of the John Mitchell map used during the negotiations of the Treaty of Paris, 1782–1783.
