In 1855 a British chemist, Alexander Parkes (1813-1890), found that pyroxylin (a partly nitrated cellulose), if dissolved in alcohol and ether in which camphor had also been dissolved, would produce a hard solid upon evaporation, which would soften and become malleable when heated.
The first of these was pyroxylin, prepared by Parkes seventeen years earlier (see 1855).
