2 Coster, John
[br]b. c. 1647 Gloucestershire, Englandd. 13 October 1718 Bristol, England[br]English innovator in the mining, smelting and working of copper.[br]John Coster, son of an iron-forge manager in the Forest of Dean, by the age of 38 was at Bristol, where he was "chief agent and sharer therein" in the new lead-smelting methods using coal fuel. In 1685 the work, under Sir Clement Clerke, was abandoned because of patent rights claimed by Lord Grandison, who financed of earlier attempts. Clerke's business turned to the coal-fired smelting of copper under Coster, later acknowledged as responsible for the subsequent success through using an improved reverberatory furnace which separated coal fume from the ores being smelted. The new technique, applicable also to lead and tin smelting, revitalized copper production and provided a basis for new British industry in both copper and brass manufacture during the following century. Coster went on to manage a copper-smelting works, and by the 1690s was supplying Esher copper-and brass-works in Surrey from his Redbrook, Gloucestershire, works on the River Wye. In the next decade he extended his activities to Cornish copper mining, buying ore and organizing ore sales, and supplying the four major copper and brass companies which by then had become established. He also made copper goods in additional water-powered rolling and hammer mills acquired in the Bristol area. Coster was ably assisted by three sons; of these, John and Robert were mainly active in Cornwall. In 1714 the younger John, with his father, patented an "engine for drawing water out of deep mines". The eldest son, Thomas, was more involved at Redbrook, in South Wales and the Bristol area. A few years after the death of his father, Thomas became partner in the brass company of Bristol and sold them the Redbrook site. He became Member of Parliament for Bristol and, by then the only surviving son, planned a large new smelting works at White Rock, Swansea, South Wales, before his death in 1734. Partners outside the family continued the business under a new name.[br]Bibliography1714, British patent 397, with John Coster Jr.Further ReadingRhys Jenkins, 1942, "Copper works at Redbrook and Bristol", Transactions of the Bristol and Gloucestershire Archaeological Society 63.Joan Day, 1974–6, "The Costers: copper smelters and manufacturers", Transactions of the Newcomen Society 47:47–58.JD -
3 Dancer, John Benjamin
SUBJECT AREA: Photography, film and optics[br]b. 1812 Englandd. 1887 England[br]English instrument maker and photographer, pioneer of microphotography.[br]The son of a scientific instrument maker, Dancer was educated privately in Liverpool, where from 1817 his father practised his trade. John Benjamin became a skilled instrument maker in his own right, assisting in the family business until his father's death in 1835. He set up on his own in Liverpool in 1840 and in Manchester in 1841. In the course of his career Dancer made instruments for several of the leading scientists of the day, his clients including Brewster, Dalton and Joule.Dancer became interested in photography as soon as the new art was announced in 1839 and practised the processes of both Talbot and Daguerre. It was later claimed that as early as 1839 he used an achromatic lens combination to produce a minute image on a daguerreotype plate, arguably the world's first microphotograph and the precursor of modern microfilm. It was not until the introduction of Archer's wet-collodion process in 1851 that Dancer was able to perfect the technique however. He went on to market a long series of microphotographs which proved extremely popular with both the public and contemporary photographers. It was examples of Dancer's microphotographs that prompted the French photographer Dagron to begin his work in the same field. In 1853 Dancer constructed a binocular stereoscopic camera, the first practicable instrument of its type. In an improved form it was patented and marketed in 1856.Dancer also made important contributions to the magic lantern. He was the first to suggest the use of limelight as an illuminant, pioneered the use of photographic lantern slides and devised an ingenious means of switching gas from one lantern illuminant to another to produce what were known as dissolving views. He was a resourceful innovator in other fields of instrumentation and suggested several other minor improvements to scientific apparatus before his working life was sadly terminated by the loss of his sight.[br]Further ReadingAnon., 1973, "John Benjamin Dancer, originator of microphotography", British Journal of Photography (16 February): 139–41.H.Gernsheim and A.Gernsheim, 1969, The History of Photography, rev. edn, London.JW
