. At this time, chemistry was still in a quite primitive state: although the atomic theory was accepted, the major elements had been discovered, and techniques to analyse 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

 could be partly transformed into a crude mixture which when extracted with alcohol produced a substance with an intense purple colour. Perkin, who had an interest in painting and photography, immediately became enthusiastic about this result and carried out further trials with his friend Arthur Church and his brother Thomas. Since these experiments were not part of the work on quinine which had been assigned to Perkin, the trio carried them out in a hut in Perkin's garden, so as to keep them secret from Hofmann.

They satisfied themselves that they might be able to scale up production of the purple substance and commercialise it as a dye, which they called mauveine

 in August 1856, when he was still only 18. At the time, all dyes used for colouring cloth were natural substances, many of which were expensive and labour-intensive to extract. Furthermore, many lacked stability, or fastness. The colour purple, which had been a mark of aristocracy and prestige since ancient times, was especially expensive and difficult to produce — the dye used, known as Tyrian purple

, was made from the glandular mucus of certain molluscs. Its extraction was variable and complicated, and so Perkin and his brother realised that they had discovered a possible substitute whose production could be commercially successful.

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. However, he was active in all of these areas: he persuaded his father to put up the capital, and his brothers to partner him in the creation of 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

After the discovery of mauveine, many new aniline dyes appeared (some discovered by Perkin himself), and factories producing them were constructed across Europe.

Later years

William Perkin continued active research in organic chemistry for the rest of his life: he discovered and marketed other synthetic dyes, including Britannia Violet and Perkin's Green ; he discovered ways to make coumarin
