62 Napier, Robert
SUBJECT AREA: Ports and shipping[br]b. 18 June 1791 Dumbarton, Scotlandd. 23 June 1876 Shandon, Dunbartonshire, Scotland[br]Scottish shipbuilder one of the greatest shipbuilders of all time, known as the "father" of Clyde shipbuilding.[br]Educated at Dumbarton Grammar School, Robert Napier had been destined for the Church but persuaded his father to let him serve an apprenticeship as a blacksmith under him. For a while he worked in Edinburgh, but then in 1815 he commenced business in Glasgow, the city that he served for the rest of his life. Initially his workshop was in Camlachie, but it was moved in 1836 to a riverside factory site at Lancefield in the heart of the City and again in 1841 to the Old Shipyard in the Burgh of Govan (then independent of the City of Glasgow). The business expanded through his preparedness to build steam machinery, beginning in 1823 with the engines for the paddle steamer Leven, still to be seen a few hundred metres from Napier's grave in Dumbarton. His name assured owners of quality, and business expanded after two key orders: one in 1836 for the Honourable East India Company; and the second two years later for the Royal Navy, hitherto the preserve of the Royal Dockyards and of the shipbuilders of south-east England. Napier's shipyard and engine shops, then known as Robert Napier and Sons, were to be awarded sixty Admiralty contracts in his lifetime, with a profound influence on ship and engine procurement for the Navy and on foreign governments, which for the first time placed substantial work in the United Kingdom.Having had problems with hull subcontractors and also with the installation of machinery in wooden hulls, in 1843 Napier ventured into shipbuilding with the paddle steamer Vanguard, which was built of iron. The following year the Royal Navy took delivery of the iron-hulled Jackall, enabling Napier to secure the contract for the Black Prince, Britain's second ironclad and sister ship to HMS Warrior now preserved at Portsmouth. With so much work in iron Napier instigated studies into metallurgy, and the published work of David Kirkaldy bears witness to his open-handedness in assisting the industry. This service to industry was even more apparent in 1866 when the company laid out the Skelmorlie Measured Mile on the Firth of Clyde for ship testing, a mile still in use by ships of all nations.The greatest legacy of Robert Napier was his training of young engineers, shipbuilders and naval architects. Almost every major Scottish shipyard, and some English too, was influenced by him and many of his early foremen left to set up rival establishments along the banks of the River Clyde. His close association with Samuel Cunard led to the setting up of the company now known as the Cunard Line. Napier designed and engined the first four ships, subcontracting the hulls of this historic quartet to other shipbuilders on the river. While he contributed only 2 per cent to the equity of the shipping line, they came back to him for many more vessels, including the magnificent paddle ship Persia, of 1855.It is an old tradition on the Clyde that the smokestacks of ships are made by the enginebuilders. The Cunard Line still uses red funnels with black bands, Napier's trademark, in honour of the engineer who set them going.[br]Principal Honours and DistinctionsKnight Commander of the Dannebrog (Denmark).

63 Pascal, Blaise
SUBJECT AREA: Electronics and information technology[br]b. 19 June 1623 Clermont Ferrand, Franced. 19 August 1662 Paris, France[br]French mathematician, physicist and religious philosopher.[br]Pascal was the son of Etienne Pascal, President of the Court of Aids. His mother died when he was 3 years old and he was brought up largely by his two sisters, one of whom was a nun at Port Royal. They moved to Paris in 1631 and again to Rouen ten years later. He received no formal education. In 1654 he was involved in a carriage accident in which he saw a mystical vision of God and from then on confined himself to philosophical rather than scientific matters. In the field of mathematics he is best known for his work on conic sections and on the laws of probability. As a youth he designed a calculating machine of which, it is said, some seventy were made. His main contribution to technology was his elucidation of the laws of hydrostatics which formed the basis of all hydrostatic machines in subsequent years. Pascal, however, did not put these laws to any practical use: that was left to the English cabinet-maker and engineer Joseph Bramah more than a century later. Suffering from indifferent health, Pascal persuaded his brother-in-law Périer to repeat the experiments of Evangelista Torricelli on the pressure of the atmosphere. This involved climbing the 4,000 ft (1,220 m) of the Puy de Dôme, a mountain close to Clermont, with a heavy mercury-in-glass barometer. The experiment was reported in the 1647 pamphlet "Expériences nouvelles touchant le vide". The Hydrostatic Law was laid down by Pascal in Traité de l'équilibre des liqueurs, published a year after his death. In this he established the fact that in a fluid at rest the pressure is transmitted equally in all directions.[br]Bibliography1647, "Expériences nouvelles touchant le vide". 1663, Traité de l'équilibre des liqueurs.Further ReadingJ.Mesnard, 1951, Pascal, His Life and Works.I.McNeil, 1972, Hydraulic Power, London: Longmans.IMcN -
64 Poniatoff, Alexander Mathew
[br]b. 25 March 1892 Kazan District, Russiad. 24 October 1980[br]Russian (naturalized American in 1932) electrical engineer responsible for the development of the professional tape recorder and the first commercially-successful video tape recorder (VTR).[br]Poniatoff was educated at the University of Kazan, the Imperial College in Moscow, and the Technische Hochschule in Karlsruhe, gaining degrees in mechanical and electrical engineering. He was in Germany when the First World War broke out, but he managed to escape back to Russia, where he served as an Air Force pilot with the Imperial Russian Navy. During the Russian Revolution he was a pilot with the White Russian Forces, and escaped into China in 1920; there he found work as an assistant engineer in the Shanghai Power Company. In 1927 he immigrated to the USA, becoming a US citizen in 1932. He obtained a post in the research and development department of the General Electric Company in Schenectady, New York, and later at Dalmo Victor, San Carlos, California. During the Second World War he was involved in the development of airborne radar for the US Navy.In 1944, taking his initials to form the title, Poniatoff founded the AMPEX Corporation to manufacture components for the airborne radar developed at General Electric, but in 1946 he turned to the production of audio tape recorders developed from the German wartime Telefunken Magnetophon machine (the first tape recorder in the truest sense). In this he was supported by the entertainer Bing Crosby, who needed high-quality replay facilities for broadcasting purposes, and in 1947 he was able to offer a professional-quality product and the business prospered.With the rapid post-war boom in television broadcasting in the USA, a need soon arose for a video recorder to provide "time-shifting" of live TV programmes between the different US time zones. Many companies therefore endeavoured to produce a video tape recorder (VTR) using the same single-track, fixed-head, longitudinal-scan system used for audio, but the very much higher bandwidth required involved an unacceptably high tape-speed. AMPEX attempted to solve the problem by using twelve parallel tracks and a machine was demonstrated in 1952, but it proved unsatisfactory.The development team, which included Charles Ginsburg and Ray Dolby, then devised a four-head transverse-scan system in which a quadruplex head rotating at 14,400 rpm was made to scan across the width of a 2 in. (5 cm) tape with a tape-to-head speed of the order of 160 ft/sec (about 110 mph; 49 m/sec or 176 km/h) but with a longitudinal tape speed of only 15 in./sec (0.38 m/sec). In this way, acceptable picture quality was obtained with an acceptable tape consumption. Following a public demonstration on 14 April 1956, commercial produc-tion of studio-quality machines began to revolutionize the production and distribution of TV programmes, and the perfecting of time-base correctors which could stabilize the signal timing to a few nanoseconds made colour VTRs a practical proposition. However, AMPEX did not rest on its laurels and in the face of emerging competition from helical scan machines, where the tracks are laid diagonally on the tape, the company was able to demonstrate its own helical machine in 1957. Another development was the Videofile system, in which 250,000 pages of facsimile could be recorded on a single tape, offering a new means of archiving information. By 1986, quadruplex VTRs were obsolete, but Poniatoff's role in making television recording possible deserves a place in history.Poniatoff was President of AMPEX Corporation until 1955 and then became Chairman of the Board, a position he held until 1970.[br]Further ReadingA.Abrahamson, 1953, "A short history of television recording", Part I, JSMPTE 64:73; 1973, Part II, Journal of the Society of Motion Picture and Television Engineers, 82:188 (provides a fuller background).Audio Biographies, 1961, ed.

65 Thomson, Sir William, Lord Kelvin
[br]b. 26 June 1824 Belfast, Ireland (now Northern Ireland)d. 17 December 1907 Largs, Scotland[br]Irish physicist and inventor who contributed to submarine telegraphy and instrumentation.[br]After education at Glasgow University and Peterhouse, Cambridge, a period of study in France gave Thomson an interest in experimental work and instrumentation. He became Professor of Natural Philosophy at Glasgow in 1846 and retained the position for the rest of his career, establishing the first teaching laboratory in Britain.Among his many contributions to science and engineering was his concept, introduced in 1848, of an "absolute" zero of temperature. Following on from the work of Joule, his investigations into the nature of heat led to the first successful liquefaction of gases such as hydrogen and helium, and later to the science of low-temperature physics.Cable telegraphy gave an impetus to the scientific measurement of electrical quantities, and for many years Thomson was a member of the British Association Committee formed in 1861 to consider electrical standards and to develop units; these are still in use. Thomson first became Scientific Adviser to the Atlantic Telegraph Company in 1857, sailing on the Agamemnon and Great Eastern during the cable-laying expeditions. He invented a mirror galvanometer and more importantly the siphon recorder, which, used as a very sensitive telegraph receiver, provided a permanent record of signals. He also laid down the design parameters of long submarine cables and discovered that the conductivity of copper was greatly affected by its purity. A major part of the success of the Atlantic cable in 1866 was due to Thomson, who received a knighthood for his contribution.Other instruments he designed included a quadrant electrostatic voltmeter to measure high voltages, and his "multi-cellular" instrument for low voltages. They could be used on alternating or direct current and were free from temperature errors. His balances for precision current measurement were widely used in standardizing laboratories.Thomson was a prolific writer of scientific papers on subjects across the whole spectrum of physics; between 1855 and 1866 he published some 110 papers, with a total during his life of over 600. In 1892 he was raised to the peerage as Baron Kelvin of Largs. By the time of his death he was looked upon as the "father" of British physics, but despite his outstanding achievements his later years were spent resisting change and progress.[br]Principal Honours and DistinctionsKnighted 1866.

66 Tompion, Thomas
SUBJECT AREA: Horology[br]baptized 25 July 1639 Ickwell Green, Englandd. 20 November 1713 London, England[br]English clock-and watchmaker of great skill and ingenuity who laid the foundations of his country's pre-eminence in that field.[br]Little is known about Tompion's early life except that he was born into a family of blacksmiths. When he was admitted into the Clockmakers' Company in 1671 he was described as a "Great Clockmaker", which meant a maker of turret clocks, and as these clocks were made of wrought iron they would have required blacksmithing skills. Despite this background, he also rapidly established his reputation as a watchmaker. In 1674 he moved to premises in Water Lane at the sign of "The Dial and Three Crowns", where his business prospered and he remained for the rest of his life. Assisted by journeymen and up to eleven apprentices at any one time, the output from his workshop was prodigious, amounting to over 5,000 watches and 600 clocks. In his lifetime he was famous for his watches, as these figures suggest, but although they are of high quality they do not differ markedly from those produced by other London watchmakers of that period. He is now known more for the limited number of elaborate clocks that he produced, such as the equation clock and the spring-driven clock of a year's duration, which he made for William III. Around 1711 he took into partnership his nephew by marriage, George Graham, who carried on the business after his death.Although Tompion does not seem to have been particularly innovative, he lived at a time when great advances were being made in horology, which his consummate skill as a craftsman enabled him to exploit. In this he was greatly assisted by his association with Robert Hooke, for whom Tompion constructed a watch with a balance spring in 1675; at that time Hooke was trying to establish his priority over Huygens for this invention. Although this particular watch was not successful, it made Tompion aware of the potential of the balance spring and he became the first person in England to apply Huygens's spiral spring to the balance of a watch. Although Thuret had constructed such a watch somewhat earlier in France, the superior quality of Tompion's wheel work, assisted by Hooke's wheel-cutting engine, enabled him to dominate the market. The anchor escapement (which reduced the amplitude of the pendulum's swing) was first applied to clocks around this time and produced further improvements in accuracy which Tompion and other makers were able to utilize. However, the anchor escapement, like the verge escapement, produced recoil (the clock was momentarily driven in reverse). Tompion was involved in attempts to overcome this defect with the introduction of the dead-beat escapement for clocks and the horizontal escapement for watches. Neither was successful, but they were both perfected later by George Graham.[br]Principal Honours and DistinctionsMaster of the Clockmakers' Company 1703.Bibliography1695, with William Houghton and Edward Barlow, British patent no. 344 (for a horizontal escapement).Further ReadingR.W.Symonds, 1951, Thomas Tompion, His Life and Work, London (a comprehensive but now slightly dated account).H.W.Robinson and W.Adams (eds), 1935, The Diary of Robert Hooke (contains many references to Tompion).D.Howse, 1970, The Tompion clocks at Greenwich and the dead-beat escapement', Antiquarian Horology 7:18–34, 114–33.DV
