First known selfie, taken by Robert Cornelius in 1839. Robert Cornelius, an American pioneer in photography, produced a daguerreotype of himself in 1839, which is also one of the first photographs of a person. Because the process was slow he was able to uncover the lens, run into the shot for a minute or more, and then replaces the lens cap. He recorded on the back "The first light Picture ever taken. 1839. Woman taking her picture in a mirror, ca. 1900. The debut of the portable Kodak Brownie box camera in 1900 led to photographic self-portraiture becoming a more widespread technique. The method was usually by mirror and stabilizing the camera either on a nearby object or on a tripod while framing via a viewfinder at the top of the box. Russian Grand Duchess Anastasia Nikolaevna at the age of 13 was one of the first teenagers to take her own picture using a mirror to send to a friend in 1914. In the letter that accompanied the photograph, she wrote, "I took this picture of myself looking at the mirror. It was very hard as my hands were trembling." The earliest usage of the word selfie has been traced to 2002 when it first appeared in an Australian internet forum (ABC Online) on 13 September. As with other new technologies, the protocols and etiquette for taking and disseminating selfies remains under development, with appropriate use a matter for consideration.
