 | | DAGUERRE, LOUIS JACQUES MANDÉ [Daguerre, Louis Jacques Mandé], 1789-1851, French scene painter and physicist, inventor of the daguerreotype, a photograph produced on a silver-coated copper plate treated with iodine vapor. |
 | | In 1829 his experiments with the daguerreotype were joined with those of J. Nicéphore Niepce, who had been doing related work since 1814. |
 | | Daguerre completed the invention of the daguerreotype alone, and in 1839 it was made public and ceded to the Academy of Sciences, only a few weeks before the rival invention of the calotype was announced by William Henry Fox Talbot. |
