David Francis Barry (1854-1934) was one of the most noted photographers of the American Indian and U.S. Army participants in the Sioux War of 1876 and is attributed with some of the most recognizable surviving images from this period in the history of the American West. Barry first came to the west in the 1870’s to apprentice under photographer O.S. Goff, who worked as the photographer at Fort Abraham Lincoln. It was from this post the Lieutenant Colonel George Armstrong Custer led his Seventh U.S. Cavalry division in May 1876 to the battle of the Little Bighorn in southwestern Montana. This is considered one of the largest collection of Barry photographs from one historic Montana family offered for public sale.
