Moses Forster Sweetser (September 23, 1848 - 1897) authored travel books on the White Mountains, Maine in 1880, Massachusetts (1889), and a handbook on the U.S. (1891).
He also wrote several biographies on artists including Guido Reni, Raphael, Fra Angelico, Sir Joshua Reynolds, Leonardo da Vinci, Bartolomé Esteban Murillo, Washington Allston, Landseer, Claude Lorraine, and Dürer.
He toured Europe and climbed in the Alps on a two-year jaunt before returning stateside and writing travel guidebooks along the lines of the Karl Baedecker's series he relied on in Europe.
The Mount Washington Observatory Collection has an image of Sweetser.
He helped encourage visitors to the White Mountains of New Hampshire with his guidebook.
