British chemist known for his accidental discovery of the first synthetic dye
the organic chemist and son of William Henry Perkin

Sir William Henry Perkin (12 March 1838 – 14 July 1907) was a British chemist and entrepreneur best known for his serendipitous discovery of the first commercial synthetic organic dye, mauveine, made from aniline. Though he failed in trying to synthesise quinine for the treatment of malaria, he became successful in the field of dyes after his first discovery at the age of 18. Perkin set up a factory to produce the dye industrially. Lee Blaszczyk, professor of business history at the University of Leeds, states, "By laying the foundation for the synthetic organic chemicals industry, Perkin helped to revolutionize the world of fashion." the youngest of the seven children of George Perkin, a successful carpenter. His mother, Sarah, was of Scottish descent and moved to East London as a child. He was baptized in the Anglican parish church of St Paul's, Shadwell, which had been connected to James Cook, Jane Randolph Jefferson (mother of Thomas Jefferson) and John Wesley. At the age of 14, Perkin attended the City of London School, where he was taught by Thomas Hall, who fostered his scientific talent and encouraged him to pursue a career in chemistry. At this time, chemistry was still primitive: although the major elements had been discovered and techniques to analyze the proportions of the elements in many compounds were in place, it was still a difficult proposition to determine the arrangement of the elements in compounds. Hofmann had published a hypothesis on how it might be possible to synthesise quinine, an expensive natural substance much in demand for the treatment of malaria. Having invented the dye, Perkin was still faced with the problems of raising the capital for producing it, manufacturing it cheaply, adapting it for use in dyeing cotton, gaining acceptance for it among commercial dyers, and creating public demand for it. He was active in all of these areas: he persuaded his father to put up the capital, and his brothers to partner with him to build a factory; he invented a mordant for cotton; he gave technical advice to the dyeing industry; and he publicised his invention of the dye. Public demand was increased when a similar colour was adopted by Queen Victoria in Britain and by Empress Eugénie, wife of Napoleon III, in France, and when the crinoline or hooped skirt, whose manufacture used a large quantity of cloth, became fashionable. Everything fell into place: with hard work and lucky timing, Perkin became rich. His will was proved on 28 August 1907 at £86,231 4s. 11d. (roughly equivalent to £ in ).

Perkin married Jemima Harriet, the daughter of John Lissett, in 1859, which resulted in two sons, (William Henry Perkin Jr. and Arthur George Perkin). Perkin's second marriage was in 1866, to Alexandrine Caroline, daughter of Helman Mollwo. They had one son (Frederick Mollwo Perkin) and four daughters. All three sons became chemists. He was knighted in 1906, and in the same year was awarded the first Perkin Medal, established to commemorate the fiftieth anniversary of his discovery of mauveine. He was President of the Society of Chemical Industry from 1884 85. Perkin was a Liveryman of the Leathersellers' Company for 46 years and was elected Master of the Company for the year 1896–97. Today blue plaques mark the sites of Perkin's home on Cable Street, by the junction with King David Lane, and the Perkin factory in Greenford, Middlesex. A portrait, by Edward Railton Catterns (1838–1909), is owned by the University of Strathclyde. On 12 March 2018, search engine Google showed a Google Doodle to mark Perkin's 180th Birthday.

In 2013, the William Perkin Church of England High School opened in Greenford, Middlesex. The school is operated by the Twyford Church of England Academies Trust (which also operates Twyford Church of England High School). The school is named after William Perkin, and has adopted a mauve uniform and colour scheme, in tribute to his discovery of mauveine.

Since 2007, when Imperial College London gained its own Royal Charter, the Academic dress of Imperial College London features purple across the range of garments to celebrate the work of Perkin. In 2015, President of the College, Professor Alice Gast, stated that: "The colour purple symbolises the spirit of endeavour and discovery, and the risk taking nature that characterises those with an Imperial education and training."
