81 Deville, Henri Etienne Sainte-Claire
SUBJECT AREA: Metallurgy[br]b. 11 March 1818 St Thomas, Virgin Islandsd. 1 July 1881 Boulogne-sur-Seine, France[br]French chemist and metallurgist, pioneer in the large-scale production of aluminium and other light metals.[br]Deville was the son of a prosperous shipowner with diplomatic duties in the Virgin Islands. With his elder brother Charles, who later became a distinguished physicist, he was sent to Paris to be educated. He took his degree in medicine in 1843, but before that he had shown an interest in chemistry, due particularly to the lectures of Thenard. Two years later, with Thenard's influence, he was appointed Professor of Chemistry at Besançon. In 1851 he was able to return to Paris as Professor at the Ecole Normale Supérieure. He remained there for the rest of his working life, greatly improving the standard of teaching, and his laboratory became one of the great research centres of Europe. His first chemical work had been in organic chemistry, but he then turned to inorganic chemistry, specifically to improve methods of producing the new and little-known metal aluminium. Essentially, the process consisted of forming sodium aluminium trichloride and reducing it with sodium to metallic aluminium. He obtained sodium in sufficient quantity by reducing sodium carbonate with carbon. In 1855 he exhibited specimens of the metal at the Paris Exhibition, and the same year Napoleon III asked to see them, with a view to using it for breastplates for the Army and for spoons and forks for State banquets. With the resulting government support, he set up a pilot plant at Jarvel to develop the process, and then set up a small company, the Société d'Aluminium at Nan terre. This raised the output of this attractive and useful metal, so it could be used more widely than for the jewellery to which it had hitherto been restricted. Large-scale applications, however, had to await the electrolytic process that began to supersede Deville's in the 1890s. Deville extended his sodium reduction method to produce silicon, boron and the light metals magnesium and titanium. His investigations into the metallurgy of platinum revolutionized the industry and led in 1872 to his being asked to make the platinum-iridium (90–10) alloy for the standard kilogram and metre. Deville later carried out important work in high-temperature chemistry. He grieved much at the death of his brother Charles in 1876, and his retirement was forced by declining health in 1880; he did not survive for long.[br]BibliographyDeville published influential books on aluminium and platinum; these and all his publications are listed in the bibliography in the standard biography by J.Gray, 1889, Henri Sainte-Claire Deville: sa vie et ses travaux, Paris.Further ReadingM.Daumas, 1949, "Henri Sainte-Claire Deville et les débuts de l'industrie de l'aluminium", Rev.Hist.Sci 2:352–7.J.C.Chaston, 1981, "Henri Sainte-Claire Deville: his outstanding contributions to the chemistry of the platinum metals", Platinum Metals Review 25:121–8.LRDBiographical history of technology > Deville, Henri Etienne Sainte-Claire

82 Mansfield, Charles Blachford
SUBJECT AREA: Chemical technology[br]b. 8 May 1819 Rowner, Hampshire, Englandd. 26 February 1855 London, England[br]English chemist, founder of coal-tar chemistry.[br]Mansfield, the son of a country clergyman, was educated privately at first, then at Winchester College and at Cambridge; ill health, which dogged his early years, delayed his graduation until 1846. He was first inclined to medicine, but after settling in London, chemistry seemed to him to offer the true basis of the grand scheme of knowledge he aimed to establish. After completing the chemistry course at the Royal College of Chemistry in London, he followed the suggestion of its first director, A.W.von Hofmann, of investigating the chemistry of coal tar. This work led to a result of great importance for industry by demonstrating the valuable substances that could be extracted from coal tar. Mansfield obtained pure benzene, and toluene by a process for which he was granted a patent in 1848 and published in the Chemical Society's journal the same year The following year he published a pamphlet on the applications of benzene.Blessed with a private income, Mansfield had no need to support himself by following a regular profession. He was therefore able to spread his brilliant talents in several directions instead of confining them to a single interest. During the period of unrest in 1848, he engaged in social work with a particular concern to improve sanitation. In 1850, a description of a balloon machine in Paris led him to study aeronautics for a while, which bore fruit in an influential book, Aerial Navigation (London, 1851). He then visited Paraguay, making a characteristically thorough and illuminating study of conditions there. Upon his return to London in 1853, Mansfield resumed his chemical studies, especially on salts. He published his results in 1855 as Theory of Salts, his most important contribution to chemical theory.Mansfield was in the process of preparing specimens of benzene for the Paris Exhibition of 1855 when a naphtha still overflowed and caught fire. In carrying it to a place of safety, Mansfield sustained injuries which unfortunately proved fatal.[br]Bibliography1851, Aerial Navigation, London. 1855, Theory of Salts, London.Further ReadingE.R.Ward, 1969, "Charles Blachford Mansfield, 1819–1855, coal tar chemist and social reformer", Chemistry and Industry 66:1,530–7 (offers a good and well-documented account of his life and achievements).LRDBiographical history of technology > Mansfield, Charles Blachford

83 Temple, Lewis
SUBJECT AREA: Ports and shipping[br]b. 1800 Richmond, Virginia, USAd. 1854 New Bedford, Massachusetts, USA[br]African-American inventor of the toggle harpoon for whaling.[br]An African-American blacksmith, he emigrated as a young man to New Bedford, Massachusetts, and set up a shop at Coffin's Wharf that was devoted to whalecraft. In 1845 he was able to establish a blacksmith's shop at Walnut Street Wharf. There, in 1848, Temple introduced his toggle harpoon. This was found to be more effective than the barb attached to a rope used up until then, and was rapidly taken up by the whaling industry. As Temple did not patent his device, many other blacksmiths were able to make it and he gained little financial return from his invention. Injuries sustained in an accident in 1853 undermined his health and he died the following year.[br]Further ReadingP.P.James, 1989, The Real McCoy: AfricanAmerican Invention and Innovation 1629– 1930, Washington, DC: Smithsonian Institution, pp. 35–7.LRD -
84 Vail, Alfred Lewis
SUBJECT AREA: Telecommunications[br]b. 25 September 1807 Morristown, New Jersey, USAd. 18 January 1859 Morristown, New Jersey, USA[br]American telegraph pioneer and associate of Samuel Morse; widely credited with the invention of "Morse" code.[br]After leaving school, Vail was initially employed at his father's ironworks in Morristown, but he then decided to train for the Presbyterian ministry, graduating from New York City University in 1836. Unfortunately, he was then obliged to abandon his chosen career because of ill health. He accidentally met Samuel Morse not long afterwards, and he became interested in the latter's telegraph experiments; in return for a share of the rights, he agreed to construct apparatus and finance the filing of US and foreign patents. Working in Morristown with Morse and Leonard Gale, and with financial backing from his father, Vail constructed around his father's plant a telegraph with 3 miles (4.8 km) of wire. It is also possible that he, rather than Morse, was largely responsible for devising the so-called Morse code, a series of dot and dash codes representing the letters of the alphabet, and in which the simplest codes were chosen for those letters found to be most numerous in a case of printer's type. This system was first demonstrated on 6 January 1838 and there were subsequent public demonstrations in New York and Philadelphia. Eventually Congress authorized an above-ground line between Washington and Baltimore, and on 24 May 1844 the epoch-making message "What hath God wrought?" was transmitted.Vail remained with Morse for a further four years, but he gradually lost interest in telegraphy and resigned, receiving no credit for his important contribution.[br]BibliographyThe Magnetic Telegraph.Further Reading1845, American Electrotelegraph 135.J.J.Fahie, 1884, A History of the Electric Telegraph to the Year 1837, London: E\&F Spon.KF -
