Elwin Roswell Sanborn (1869 – December 19, 1947) was the first official photographer for the New York Zoological Park, now known as the Bronx Zoo. A self-taught photographer, Sanborn learned to photograph wildlife by doing it. He recorded nearly every species that came into the Bronx Zoo during the first three decades of the twentieth century using black and white photography.
Elwin Roswell Sanborn began his career at the Bronx Zoo in 1899, the same year it opened to the public on 265 acres in the northwestern area of the Bronx.
