Sir William Henry Perkin, (born March 12, 1838, London, England—died July 14, 1907, Sudbury, near Harrow, Middlesex), British chemist who discovered aniline dyes.
In 1853 Perkin entered the Royal College of Chemistry, London, where he studied under August Wilhelm von Hofmann. While Perkin was working as Hofmann’s laboratory assistant, he undertook the synthesis of quinine. He obtained instead a bluish substance with excellent dyeing properties that later became known as aniline purple, Tyrian purple, or mauve.
