I. Osgood Carlton and the First Map of Maine

Osgood Carleton (1741-1816) was the key figure in the early mapping of the Eastern District of the Commonwealth of Massachusetts: Maine. A land surveyor and teacher of the mathematical arts in Boston, he compiled existing manuscript maps and plans into maps of the district for books on U.S. geography [map 1] and Maine history [2], in 1793 and 1795 respectively. These were the first printed maps of Maine.
