Alexander Parkes (1813-1890), chemist and inventor noted for his development of various industrial processes and materials but particularly the material which was the basis for the first "plastic",
Much of Alexander Parkes's work was related to metallurgy. He was one of the first to propose introducing small amounts of phosphorus into metal alloys to enhance their strength. In all he took out 66 patents.

1841 Another of Parkes's important contributions was the discovery of the cold vulcanization process (1841), a method of waterproofing fabrics by means of a solution of rubber and carbon disulfide. This was carried out by Elkington, Mason and Co for a number of years.
1846 Charles Macintosh and Co purchased the cold cure process for £5,000.
1850 Jane Henshall Parkes died
1850 Moved to South Wales to supervise the erection of Elkington, Mason and Co's copper-smelting works based on his patent which he had sold to the Elkingtons.
1850 One of Parkes' most significant inventions was a method of extracting silver from lead ore. This procedure, commonly called the Parkes process, involves adding zinc to lead and melting the two together. When stirred, the molten zinc reacts and forms compounds with any silver and gold present in the lead. These zinc compounds are lighter than the lead and, on cooling, form a crust that can be readily removed. This was used at Sims' works at Llanelly.

1853 Left South Wales
1854 Married Mary Ann Roderick in Gloucester
c.1855 Parkes also produced a flexible, durable material called Parkesine from a mixture of chloroform and castor oil that led to the development of the first plastic, celluloid. Parkesine was displayed at the 1862 Great International Exhibition in London and the 1867 exhibition in Paris, receiving medals on both occasions.
