DAGUERRE, LOUIS JACQUES MANDE (da-gar'), a French inventor; born in Cormeilles, Seine-et-Oise, in 1789. He was a scene-painter at Paris, and as early as 1814 had his attention directed by Nic^phore Niepce to the subject of photographic pictures on metal. In 1829 they made a formal agreement to work out the invention together, but it was not till after Niepce's death, on July 5, 1833, that Daguerre succeeded in perfecting the process since called daguerreotype. The new process excited the greatest in- terest. Daguerre was made an officer of the Legion of Honor, and an annuity of 6,000 francs was settled on him. Da- guerre died July 10, 1851. DAGUERREOTYPE PROCESS, the original photographic process, consisting in sensitizing a silver plate with the vapor of iodine, and then placing it in a camera obscura previously focused, and afterward developing the picture by vapor of mercury. It is then fixed by immersion in hyposulphate of sodium. After thorough washing and drying the picture is covered with glass to prevent its being rubbed off. Daguerreotype has now been superseded by the collodion and other processes. See Photography.
