Frederick Scott Archer

Died 2 May 1857 (born 1813).English inventor of the wet-collodian process, the first practical photographic process which enabled making additional copies of a picture, that was used from 1851 until about 1880.

By 1848, he had discovered that collodion, a solution of gun-cotton in ether, could make plates superior to either Henry Talbot's calotype or the daguerrotype. Although sensitivity required fresh preparation and use while still moist, this new “wet plate”photography was favoured for three decades. Having never patented his process, Archer made no commercial gain for his process, and was in poverty when he died.«
