17 Caro, Heinrich
[br]b. 13 February 1834 Poznan, Polandd. 11 October 1911 Dresden, Germany[br]German dyestuffi chemist.[br]Caro received vocational training as a dyer at the Gewerbeinstitut in Berlin from 1852, at the same time attending chemistry lectures at the university there. In 1855 he was hired as a colourist by a firm of calico printers in Mulheim an der Ruhr, where he was able to demonstrate the value of scientific training in solving practical problems. Two years later, the year after Perkin's discovery of aniline dyes, he was sent to England in order to learn the latest dyeing techniques. He took up a post an analytical chemist with the chemical firm Roberts, Dale \& Co. in Manchester; after finding a better way of synthesizing Perkin's mauve, he became a partner in the business. Caro was able to enlarge both his engineering experience and his chemical knowledge there, particularly by studying Hofmann's researches on the aniline dyes. He made several discoveries, including induline, Bismark brown and Martius yellow.Like other German chemists, however, he found greater opportunities opening up in Germany, and in 1866 he returned to take up a post in Bunsen's laboratory in Heidelberg. In 1868 Caro obtained the important directorship of Badische Anilin-Soda- Fabrik (BASF), the first true industrial research organization and leading centre of dyestuffs research. A steady stream of commercial successes followed. In 1869, after Graebe and Liebermann had showed him their laboratory synthesis of the red dye alizarin, Caro went on to develop a cheaper and commercially viable method. During the 1870s he collaborated with Adolf von Baeyer to make methylene blue and related dyes, and then went on to the azo dyes. His work on indigo was important, but was not crowned with commercial success; that came in 1897 when his successor at BASF discovered a suitable process for producing indigo on a commercial scale. Caro had resigned his post in 1889, by which time he had made notable contributions to German supremacy in the fast-developing dyestuffs industry.[br]Further ReadingA.Bernthsen, 1912, obituary, Berichte derDeutschen Chemischen Gesellschaft, 45; 1,987–2,042 (a substantial obituary).LRD -
18 Perkin, Sir William Henry
[br]b. 12 March 1838 London, Englandd. 14 July 1907 Sudbury, England[br]English chemist, discoverer of aniline dyes, the first synthetic dyestuffs.[br]He early showed an aptitude for chemistry and in 1853 entered the Royal College of Chemistry as a student under A.W.von Hofmann, the first Professor at the College. By the end of his first year, he had carried out his first piece of chemical research, on the action of cyanogen chloride on phenylamine, which he published in the Journal of the Chemical Society (1857). He became honorary assistant to von Hofmann in 1857; three years previously he had set up his own chemical laboratory at home, where he had discovered the first of the azo dyes, aminoazonapththalene. In 1856 Perkin began work on the synthesis of quinine by oxidizing a salt of allyl toluidine with potassium dichromate. Substituting aniline, he obtained a dark-coloured precipitate which proved to possess dyeing properties: Perkin had discovered the first aniline dye. Upon receiving favourable reports on the new material from manufacturers of dyestuffs, especially Pullars of Perth, Perkin resigned from the College and turned to the commercial exploitation of his discovery. This proved highly successful. From 1858, the dye was manufactured at his Greenford Green works as "Aniline Purple" or "Tyrian Purple". It was later to be referred to by the French as mauve. Perkin's discovery led to the development of the modern dyestuffs industry, supplanting dyes from the traditional vegetable sources. In 1869, he introduced two new methods for making the red dye alizarin, in place of the process that involved the use of the madder plant (Rubia tinctorum). In spite of German competition, he dominated the British market until the end of 1873. After eighteen years in chemical industry, Perkin retired and devoted himself entirely to the pure chemical research which he had been pursuing since the 1850s. He eventually contributed ninety papers to the Chemical Society and further papers to other bodies, including the Royal Society. For example, in 1867 he published his synthesis of unsaturated organic acids, known as "Perkin's synthesis". Other papers followed, on the structure of "Aniline Purple". In 1881 Perkin drew attention to the magnetic-rotatory power of some of the substances he had been dealing with. From then on, he devoted particular attention to the application of this phenomenon to the determination of chemical structure.Perkin won wide recognition for his discoveries and other contributions to chemistry.The half-centenary of his great discovery was celebrated in July 1906 and later that year he received a knighthood.[br]Principal Honours and DistinctionsKnighted 1906.
