2 Bright, Sir Charles Tilston
SUBJECT AREA: Telecommunications[br]b. 8 June 1832 Wanstead, Essex, Englandd. 3 May 1888 Abbey Wood, London, England[br]English telegraph engineer responsible for laying the first transatlantic cable.[br]At the age of 15 years Bright left the London Merchant Taylors' School to join the two-year-old Electric Telegraph Company. By 1851 he was in charge of the Birmingham telegraph station. After a short time as Assistant Engineer with the newly formed British Telegraph Company, he joined his brother (who was Manager) as Engineer-in-Chief of the English and Irish Magnetic Telegraph Company in Liverpool, for which he laid thousands of miles of underground cable and developed a number of innovations in telegraphy including a resistance box for locating cable faults and a two-tone bell system for signalling. In 1853 he was responsible for the first successful underwater cable between Scotland and Ireland. Three years later, with the American financier Cyrus Field and John Brett, he founded and was Engineer-in-chief of the Atlantic Telegraph Company, which aimed at laying a cable between Ireland and Newfoundland. After several unsuccessful attempts this was finally completed on 5 August 1858, Bright was knighted a month later, but the cable then failed! In 1860 Bright resigned from the Magnetic Telegraph Company to set up an independent consultancy with another engineer, Joseph Latimer Clark, with whom he invented an improved bituminous cable insulation. Two years later he supervised construction of a telegraph cable to India, and in 1865 a further attempt to lay an Atlantic cable using Brunel's new ship, the Great Eastern. This cable broke during laying, but in 1866 a new cable was at last successfully laid and the 1865 cable recovered and repaired. The year 1878 saw extension of the Atlantic cable system to the West Indies and the invention with his brother of a system of neighbourhood fire alarms and even an automatic fire alarm.In 1861 Bright presented a paper to the British Association for the Advancement of Science on the need for electrical standards, leading to the creation of an organization that still exists in the 1990s. From 1865 until 1868 he was Liberal MP for Greenwich, and he later assisted with preparations for the 1881 Paris Exhibition.[br]Principal Honours and DistinctionsKnighted 1858. Légion d'honneur.

3 Plimsoll, Samuel
SUBJECT AREA: Ports and shipping[br]b. 10 February 1824 Bristol, Englandd. 8 June 1898 Folkestone, Kent, England[br]English inventor of the Plimsoll Line on ships.[br]Plimsoll was educated privately and at Dr Eadon's school in Sheffield. On leaving school he became Clerk to a solicitor and then to a brewery, where he rose to become Manager. In 1851 he acted as an honorary secretary to the Great Exhibition. Two years later he went to London and set up as a coal merchant: he published two pamphlets on the coal trade in 1862. After several unsuccessful attempts, he managed to be elected as Member of Parliament for Derby in 1868, in the Radical interest. He concerned himself with mercantile shipping and in 1870 he began his campaign to improve safety at sea, particularly by the imposition of a load-line on vessels to prevent dangerous overloading. In 1871 he introduced a resolution into the House of Commons and also a bill, the Government also having proposed one on the same subject, but strong opposition from the powerful shipping-business interest forced a withdrawal. Plimsoll published a pamphlet, Our Seamen, bitterly attacking the shipowners. This aroused public feeling and controversy, and under pressure the Government appointed a Royal Commission in 1873, under the chairmanship of the Duke of Somerset, to examine the matter. Their report did not support Plimsoll's proposal for a load-line, but that did not prevent him from bringing forward his own bill, which was narrowly defeated by only three votes. The Government then introduced its own merchant shipping bill in 1875, but it was so mauled by the Opposition that the Prime Minister, Disraeli, threatened to withdraw it. That provoked a violent protest from Plimsoll in the House, including a description of the shipowners which earned him temporary suspension from the House. He was allowed to return after an apology, but the incident served to heighten public feeling for the seamen. The Government were obliged to hustle through the Merchant Shipping Act 1876, which ensured, among other things, that ships should be marked with what has become universally known as the Plimsoll Line; Plimsoll himself became known as "The Seamen's Friend".In 1880 he relinquished his parliamentary seat at Derby, but he continued his campaign to improve conditions for seamen and to ensure that the measures in the Act were properly carried out.LRD -
4 Field, Cyrus West
SUBJECT AREA: Telecommunications[br]b. 30 November 1819 Stockbridge, Massachusetts, USAd. 12 July 1892 New York City, New York, USA[br]American financier and entrepreneur noted for his successful promotion of the first transatlantic telegraph cable.[br]At the age of 15 Field left home to seek his fortune in New York, starting work on Broadway as an errand boy for $1 per week. Returning to Massachusetts, in 1838 he became an assistant to his brother Matthew, a paper-maker, leaving to set up his own business two years later. By the age of 21 he was also a partner in a New York firm of paper wholesalers, but this firm collapsed because of large debts. Out of the wreckage he set up Cyrus W.Field \& Co., and by 1852 he had paid off all the debts. With $250,000 in the bank he therefore retired and travelled in South America. Returning to the USA, he then became involved with the construction of a telegraph line in Newfoundland by an English engineer, F.N. Osborne. Although the company collapsed, he had been fired by the dream of a transatlantic cable and in 1854 was one of the founders of the New York, Newfoundland and London Telegraph Company. He began to promote surveys and hold discussions with British telegraph pioneers and with Isambard Brunel, who was then building the Great Eastern steamship. In 1856 he helped to set up the Atlantic Telegraph Company in Britain and, as a result of his efforts and those of the British physicist and inventor Sir William Thomson (Lord Kelvin), work began in 1857 on the laying of the first transatlantic cable from Newfoundland to Ireland. After many tribulations the cable was completed on 5 August 1857, but it failed after barely a month. Following several unsuccessful attempts to repair and replace it, the cable was finally completed on 27 July 1866. Building upon his success, Field expanded his business interests. In 1877 he bought a controlling interest in and was President of the New York Elevated Railroad Company. He also helped develop the Wabash Railroad and became owner of the New York Mail and Express newspaper; however, he subsequently suffered large financial losses.[br]Principal Honours and DistinctionsCongressional Gold Medal.Further ReadingA.C.Clarke, 1958, Voice Across the Sea, London: Frederick Muller (describes the development of the transatlantic telegraph).H.M.Field, 1893, Story of the Atlantic Telegraph (also describes the transatlantic telegraph development).L.J.Judson (ed.), 1893, Cyrus W.Field: His Life and Work (a complete biography).KF -
5 Niepce, Joseph Nicéphore
SUBJECT AREA: Photography, film and optics[br]b. 1765 Franced. 5 July 1833 Chalon, France[br]French inventor who was the first to produce permanent photographic images with the aid of a camera.[br]Coming from a prosperous family, Niepce was educated in a Catholic seminary and destined for the priesthood. The French Revolution intervened and Niepce became an officer in an infantry regiment. An attack of typhoid fever in Italy ended his military career, and he returned to France and was married. Returning to his paternal home in Chalon in 1801, he joined with his brother Claude to construct an ingenious engine called the pyréolophore, which they patented in 1807. The French Government also encouraged the brothers in their attempts to produce large quantities of indigo-blue dye from wood, a venture that was ultimately unsuccessful.Nicéphore began to experiment with lithography, which led him to take an interest in the properties of light-sensitive materials. He pursued this interest after Claude moved to Paris in 1816 and is reported to have made negative images in a camera obscura using paper soaked in silver chloride. Niepce went on to experiment with bitumen of judea, a substance that hardened on exposure to light. In 1822, using bitumen of judea on glass, he produced a heliograph from an engraving. The first images from nature may have been made as early as 1824, but the world's earliest surviving photographic image was made in 1826. A view of the courtyard of Niepce's home in Chalon was captured on a pewter plate coated with bitumen of judea; an exposure of several hours was required, the softer parts of the bitumen being dissolved away by a solvent to reveal the image.In 1827 he took examples of his work to London where he met Francis Bauer, Secretary of the Royal Society. Nothing came of this meeting, but on returning to France Niepce continued his work and in 1829 entered into a formal partnership with L.J.M. Daguerre with a view to developing their mutual interest in capturing images formed by the camera obscura. However, the partnership made only limited progress and was terminated by Niepce's death in 1833. It was another six years before the announcement of the first practicable photographic processes was made.[br]Bibliography1973.
