Sir William Perkin (1838-1907) was an English chemist and inventor, who in his youth was enthused about chemistry by attending public lectures by Faraday. While experimenting to synthesize quinine from a coal tar chemical, Perkins mixed aniline and sodium dichromate and unexpectedly found a dense colour, which he extracted with alcohol. He had discovered the first artificial dye. Textiles of his era were coloured from natural sources; his was a valuable alternative. At the age of 18, he patented the dye. His father invested in his efforts to manufacture the dye. It went on sale in 1857, and it became popular in France. By age 23 he was fathering a new synthetic organic chemical industry. He continued synthesis research. He was knighted in 1906.
