Abstract. The French-born artist Trouvelot arrived in the United States in 1855. His interest in astronomy began with his observations and sketches of spectacular auroras in the 1870s. This work drew the interest of Harvard College Observatory astronomers and he was invited to join the staff. Using Harvard’s 15-inch refractor and other telescopes, Trouvelot made many drawings of celestial objects. He was invited to Washington in 1875 to use the Naval Observatory’s
