Robert Cornelius
American photographer and pioneer who took the first known photographic portrait of a person in the United States — a daguerreotype self-portrait taken in 1839.
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 — and a landmark achievement for self-portraiture in the history of the medium.

I

Photography

Cornelius operated some of the earliest photography studios in the United States between 1840 and 1842, implementing innovative techniques to significantly reduce the exposure time required for portraits. His work helped make portrait photography accessible at a time when the process was still slow and technically demanding.

Life & Inventions

Cornelius was an inventor, businessman, and lamp manufacturer. He created and patented the "solar lamp" in 1843, which burned brighter and allowed for the use of cheaper lard as a fuel source rather than more expensive whale oil. This invention had a practical impact on everyday life well beyond his contributions to photography.
