Robert Cornelius was an American photographer and pioneer in the history of photography. His daguerreotype self-portrait taken in 1839 is generally accepted as the first known photographic portrait of a person taken in the United States, the second in the world, and a significant achievement for self-portraiture. He operated some of the earliest photography studios in the United States between 1840 and 1842 and implemented innovative techniques to significantly reduce the exposure time required for portraits.
