Louis Jacques Mande
He was the inventor of the daguerreotype, a photograph produced on a silver-coated copper plate treated with iodine vapor. Around 1826 he - in conjunction with Nicephore Niepce - perfected the photographic process named after him. Until Niepce's death in 1833 they worked together on the photographic process. Daguerre completed the invention of the daguerreotype alone, and in 1839 it was made public and ceded to the Academy of Sciences.
