Louis Jacques Mande Daguerre
Louis Jacques Mande Daguerre, (1787-1851), French painter and inventor of the daguerreotype, born at Cormeilles, Seina-et-Oise. He became an artist, and with Pierre Prevost executed a number of panoramic views. In 1822 he established a pictorial exhibition called the diorama, which was so successful that he opened another one in London. But his great ambition was to produce permanent pictures by means of sunlight, and in 1829 he joined with J. N. Niepce, who had already been working for years at the same problem.
Niepce died in 1833, but Daguerre persevered until he succeeded in producing such pictures on an iodised silver plate, called after him daguerreotypes. First described in 1839, the process remained in use until the late 1850s. He wrote many works on this subject, including Historique et description des precedes de daguerreotypie, 1839. His success was rewarded with the decoration of the Legion of Honour, and annuities for himself and Niepce's representative.
