Louis-Jacques-Mandé Daguerre
November 18th, 1787 to July 10th, 1851

Daguerre was a "French painter and physicist who invented the daguerreotype, the first practical process of photography. Though the first permanent photograph from nature was made in 1826/27 by Joseph-Nicéphore Niepce of France, it was of poor quality and required about eight hours' exposure time. The process that Daguerre developed required only 20 to 30 minutes. The two became partners in the development of Niepce's heliographic process from 1829 until the death of Niepce in 1833. Daguerre continued his experiments, and he discovered that exposing an iodized silver plate in a camera would result in a lasting image after a chemical fixing process."

In the past I worked with many of the obsolete photographic process [Bromoil, Carbon, Cyanotype. Daguerreotype, Ferro-gallic, Gum-bichromate] and all had their own peculiar difficulties but the Daguerreotype was the most complex and hazardous.
