John Montresor was a British military engineer and cartographer who worked in North America.
His father was a military engineer and his youth was spent in British Gibraltar. Montresor studied in London, and in 1754 accompanied his father to North America when he was appointed chief engineer to Major General Edward Braddock's troops. John participated in various expeditions, delivered dispatches, and witnessed the sieges of Louisbourg and Quebec. During his service, he also did the necessary research and prepared maps of Acadia, the St. Lawrence River, and his route along the Kennebec River.
One of John Montresor's major accomplishments is the strategic map of the Hudson River, one of the most detailed maps of the New York City area during the American Revolution, first published in 1775. The map extends from Lake Champlain down the Hudson to Long Island, with insets of Lake Champlain and the White Hills in the upper Connecticut Valley.
John Montresor was promoted to captain in 1776, returned to England in 1779, and retired from the army. He died in prison 20 years later, accused of excessive spending while in the service.
