Louis Daguerre
Louis Daguerre (1787-1851), French inventor of the daguerreotype, an early photographic process. A successful painter of panoramic views, he began work on the production of single positive photographic images with Nicéphore Niépce in 1829. Daguerre eventually succeeded in producing such images by ex-posing an iodized silver plate and developing and fixing the image produced. As the first practical form of photography, the daguerreotype was much used for portraits from the 1830s to the 1850s.
