The collection of Civil War stereographs from the New-York Historical Society's Department of Prints, Photographs, and Architectural Collections covers the entire period of the Civil War, from the first Battle of Bull Run through the surrender at Appomattox, and the triumphal parade of Union forces in Washington D.C. Most of the images were made in the eastern theatre of the war, with a majority of scenes from Virginia. Compelling images of death on the battlefield and the destruction of cities, railroads and bridges show the devastating effects of the war. Individual and group portraits of participants are included, along with images of soldiers relaxing in camps, drilling in the field, and preparing for attack in trenches and other fortifications. There are images of African Americans fleeing slavery by crossing the Union lines, as well as African Americans on southern plantations and serving in the Army and the Navy. Because of their journalistic style, stereographs offer an immediate and graphic look at the war. When seen with a stereograph viewer which creates a three-dimensional effect, the small views (which range in size from 3 1/8 x 6 3/4 inches to 4 x 7 inches) become even more vivid and detailed. While photographers did not usually depict actual battle scenes, they captured images of camp life before battles and of battlefields afterward. Significant Civil War sites are documented, including Fort Sumter and the house at Appomattox where Lee surrendered. These views are also significant because of the photographers who made them. Mathew Brady is represented in the collection, as well as his former employees Alexander Gardner, James Gibson, and Timothy O'Sullivan. Other photographers represented include George N. Barnard, who took photographs in Virginia and the Carolinas, Sam A. Cooley, who was the 'Official Photographer' for the 10th Army Corps, and local photographers from Richmond, Gettysburg, and other locations. The 732 stereographs presented here came to the Society from various sources, although most were acquired in 1960 and 1961 from George T. Bagoe (1886?-1948), who specialized in collecting Civil War stereographs, among other subjects. Other significant groups of views were acquired in 1922, 1923 and 1936.
