Georges-Louis Le Rouge (c. 1712-c. 1790) was the most prolific publisher of maps and charts of North America during the period of the American Revolution. He published both an atlas of charts, in which the present work appeared—the Neptune Americo-Septentrional—and the Atlas Ameriquain Septentrional, also in 1778, described as “the best collection of French maps for North America during the Revolutionary War” (Cobb, Krieger). A former German military officer, Le Rouge established a successful map business in Paris and attained the title of “Ingenieur Geographe du Roi.”
