Mathew B. Brady (May 18 1822 – January 15, 1896) was one of the first American photographers, best known for his scenes of the Civil War.

He studied under inventor Samuel F. B. Morse, who pioneered the daguerreotype technique in America. Brady opened his own studio in New York in 1844, and photographed Andrew Jackson and John Quincy Adams, among other celebrities. When the Civil War started, his use of a mobile studio and darkroom enabled vivid battlefield photographs that brought home the reality of war to the public. Thousands of war scenes were captured, as well as portraits of generals and politicians on both sides of the conflict, though most of these were taken by his assistants, rather than by Brady himself.
