Sir William Perkin

Died 14 Jul 1907 at age 69 (born 12 Mar 1838). Sir William Henry Perkin was an English chemist and inventor who, in his youth, was enthused about chemistry by attending public lectures by Michael Faraday. While experimenting to synthesize quinine from a coal tar chemical, Perkins mixed aniline and sodium dichromate and unexpectedly found a dense colour - he named as aniline purple - 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.
