About the author
Born in Bath, Maine, in 1846, Henry Gannett studied at Harvard before building a career that linked exploration, statistics, and mapmaking. He worked on the Hayden Survey in the American West and later became one of the central figures in the early United States Geological Survey, where his work helped establish modern topographic mapping in the United States.
He is often described as the "father of mapmaking in America," a nickname tied to his long influence on federal surveying and geographic standards. Beyond field and survey work, he also contributed to census geography and produced gazetteers, reports, and other reference works that helped readers understand the physical and human landscape of the country.
Gannett died in 1914, but his reputation endured through the institutions and mapping practices he helped build. For readers interested in exploration, geography, or the growth of American scientific work, his life offers a window into the era when much of the nation was being systematically charted for the first time.
