Wilson (1838-1903) began his career in the mid 1860s in Philadelphia and remained in that city until his death. He was the founder and influential publisher of the Philadelphia Photographer Magazine and served as an officer of the Photographic Society of the United States. Wilson's "Centennial Photographic Company" made hundreds of stereoscopic negative for the Centennial Exposition of the United States in 1876, and duplicated their efforts for the "World's Industrial and Cotton Exposition" held in New Orleans from December 1884 until June 1885. It is unknown if this image was taken in New Orleans or Philadelphia, but is the first mammoth plate we have seen by Wilson.
