SEE ALSO DARLOT & JAMIN, successor to this company. Production was mainly of Petzal lenses. Jamin was at 14, Rue Chapon, Paris. Darlot probably began work here. Certainly he was later at 125, Boulevarde Voltaire, Paris. The company was founded by J. Th. Jamin in 1822 (ie it was pre-photographic) and was purchased by Darlot (1828-1895), a former employee, sometime between 1855-1860, with lenses carrying both names from around 1860-1861 until the early 1870s.
