William Henry Jackson
William Henry Jackson (April 4, 1843 – June 30, 1942) was an American photographer, Civil War veteran, painter, and an explorer famous for his images of the American West. In 1866 Jackson boarded a Union Pacific Railroad train and traveled until it reached the end of the line at that time, about one hundred miles west of Omaha, Nebraska, where he then joined a wagon train heading west to Great Salt Lake as a bullwhacker, on the Oregon Trail. In 1867 along with his brother Edward Jackson he settled down in Omaha and entered the photography business. On ventures that often lasted for several days, Jackson acted as a missionary around the Omaha region, and it was there that Jackson made his now famous photographs of the American Indians: Osages, Otoes, Pawnees, Winnebagoes and Omahas.
