Moses Greenleaf (1777-1834) was Maine’s pioneer mapmaker. An outspoken advocate of Maine statehood and economic development, he prepared his first map in 1815 [map 7] to accompany his demonstration that Maine deserved independence: A Statistical View of the District of Maine (Boston: Cummings and Hilliard, 1816). This map was the first to depict the interior lakes and rivers of Maine with any degree of accuracy. Greenleaf’s 1820 reissue — the first map of the State of Maine — shows improvements in the delineation of several features, including Moosehead Lake [8].
