Timothy O’Sullivan

c.1840 (?New York) – 1882 (Staten Island, N.Y.)

O’Sullivan was employed as a photographer by Brady and was one of those sent out to cover, memorably, the Civil War. He had probably been taught the process by another of Brady’s employees, Gardner. King, who appears to have got on well with him, invited him on various expeditions in the American West and South-West.
