Biographical Note
Photographer Mathew Brady is represented, as well as his former employees Alexander Gardner, James Gibson, and Timothy O'Sullivan, who set up their own firm in 1863 because they wanted credit for their work which had previously all appeared under Brady's name. Other photographers include George N. Barnard, who photographed 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.
