A Parisian college professor, Martin originated the ferrotype, or tintype-images produced on black lacquered tinned iron by the wetcollodion process. He described the process in 1852 and 1853 in memoirs he presented to the Academie des Sciences. Also, Martin experimented in the production of guncotton (pyroxylin), and, in aid- ing the Paris Observatory, he constructed "a reflection mirror of greater dimensions than had been achieved before that time " (Eder). Also, he developed a procedure for silver-plating mirror surfaces with invert sugar and silver nitrate, and he was concerned with the calculation of photographic lenses.
