Daguerreotype
Invented by Louis-Jacques-Mandé Daguerre and introduced worldwide in 1839, daguerreotype was almost completely superseded by 1860 with new, less expensive processes yielding more readily viewable images. In the late 20th century, there was a revival of daguerreotypy by a small number of photographers interested in making artistic use of early photographic processes.
Boulevard du Temple
A photograph of this street was taken in 1838 by Louis Daguerre from high in his 350-seat Diorama Building at 4, Rue Sanson, where it intersected with the Rue des Marais, and which from the rear looked out roughly southwards over the rooftops towards Boulevard du Temple (since demolished, the place where it stood is at the south side of Rue Léon Jouhaux just off the north corner of Place de la République). The image is one of the earlier Daguerreotypes (invented 1837), and it is thus believed to be the earliest surviving photograph showing a person.
