Benjamin W. Kilburn is remembered both as a visual historian of immigration and international tourism and as the world's most extensive manufacturer of stereoscopic views from 1865 to 1910. He became a pioneer of photojournalism documenting the presidential inauguration of Grover Cleveland, the Johnstown Flood in Pennsylvania, the Boer War, the Boxer Rebellion, and the Spanish-American War, among other events. He also is credited with invention of a photo gun camera, which was manufactured by Scovill Mfg. Co. from 1882 to 1886, to circumvent the tripod usage while taking pictures among the White Mountains, New Hampshire.
