21 Watts, Philip
SUBJECT AREA: Ports and shipping[br]b. 30 May 1846 Portsmouth, Englandd. 15 March 1926 probably London, England[br]English naval architect, shipbuilding manager and ultimately Director of Naval Construction.[br]Since he had a long family connection with the naval base at Portsmouth, it is not surprising that Watts started to serve his apprenticeship there in 1860. He was singled out for advanced training and then in 1866 was one of three young men selected to attend the Royal School of Naval Architecture at South Kensington in London. On completing his training he joined the technical staff, then had a period as a ship overseer before going to assist William Froude for two years, an arrangement which led to a close friendship between Watts and the two Froudes. Some interesting tasks followed: the calculations for HM Armoured Ram Polyphemus; the setting up of a "calculating" section within the Admiralty; and then work as a constructor at Chatham Dockyard. In 1885 the first major change of direction took place: Watts resigned from naval service to take the post of General Manager of the Elswick shipyard of Sir W.G.Armstrong. This was a wonderful opportunity for an enthusiastic and highly qualified man, and Watts rose to the challenge. Elswick produced some of the finest warships at the end of the nineteenth century and its cruisers, such as the Esmeralda of the Chilean Navy, had a legendary name.In 1902 he was recalled to the Navy to succeed Sir William White as Director of Naval Construction (DNC). This was one of the most exciting times ever in warship design and it was during Watts's tenure of the post that the Dreadnought class of battleship was produced, the submarine service was developed and the destroyer fleet reached high levels of performance. It has been said that Watts's distinct achievements as DNC were greater armament per ton displacement, higher speeds and better manoeuvring, greater protection and, almost as important, elegance of appearance. Watt retired in 1912 but remained a consultant to the Admiralty until 1916, and then joined the board of Armstrong Whitworth, on which he served until his death.[br]Principal Honours and DistinctionsKnighted 1905. FRS 1900. Chairman, Board of Trade's Load Line Committee 1913. Vice-President, Society for Nautical Research (upon its founding), and finally Chairman for the Victory preservation and technical committee. Honorary Vice-President, Institution of Naval Architects 1916. Master of the Worshipful Company of Shipwrights 1915.BibliographyWatts produced many high-quality technical papers, including ten papers to the Institution of Naval Architects.FMW -

33 Goldmark, Peter Carl
[br]b. 2 December 1906 Budapest, Hungaryd. 7 December 1977 Westchester Co., New York, USA[br]Austro-Hungarian engineer who developed the first commercial colour television system and the long-playing record.[br]After education in Hungary and a period as an assistant at the Technische Hochschule, Berlin, Goldmark moved to England, where he joined Pye of Cambridge and worked on an experimental thirty-line television system using a cathode ray tube (CRT) for the display. In 1936 he moved to the USA to work at Columbia Broadcasting Laboratories. There, with monochrome television based on the CRT virtually a practical proposition, he devoted his efforts to finding a way of producing colour TV images: in 1940 he gave his first demonstration of a working system. There then followed a series of experimental field-sequential colour TV systems based on segmented red, green and blue colour wheels and drums, where the problem was to find an acceptable compromise between bandwidth, resolution, colour flicker and colour-image breakup. Eventually he arrived at a system using a colour wheel in combination with a CRT containing a panchromatic phosphor screen, with a scanned raster of 405 lines and a primary colour rate of 144 fields per second. Despite the fact that the receivers were bulky, gave relatively poor, dim pictures and used standards totally incompatible with the existing 525-line, sixty fields per second interlaced monochrome (black and white) system, in 1950 the Federal Communications Commission (FCC), anxious to encourage postwar revival of the industry, authorized the system for public broadcasting. Within eighteen months, however, bowing to pressure from the remainder of the industry, which had formed its own National Television Systems Committee (NTSC) to develop a much more satisfactory, fully compatible system based on the RCA three-gun shadowmask CRT, the FCC withdrew its approval.While all this was going on, Goldmark had also been working on ideas for overcoming the poor reproduction, noise quality, short playing-time (about four minutes) and limited robustness and life of the long-established 78 rpm 12 in. (30 cm) diameter shellac gramophone record. The recent availability of a new, more robust, plastic material, vinyl, which had a lower surface noise, enabled him in 1948 to reduce the groove width some three times to 0.003 in. (0.0762 mm), use a more lightly loaded synthetic sapphire stylus and crystal transducer with improved performance, and reduce the turntable speed to 33 1/3 rpm, to give thirty minutes of high-quality music per side. This successful development soon led to the availability of stereophonic recordings, based on the ideas of Alan Blumlein at EMI in the 1930s.In 1950 Goldmark became a vice-president of CBS, but he still found time to develop a scan conversion system for relaying television pictures to Earth from the Lunar Orbiter spacecraft. He also almost brought to the market a domestic electronic video recorder (EVR) system based on the thermal distortion of plastic film by separate luminance and coded colour signals, but this was overtaken by the video cassette recorder (VCR) system, which uses magnetic tape.[br]Principal Honours and DistinctionsInstitute of Electrical and Electronics Engineers Morris N.Liebmann Award 1945.

34 Grimthorpe (of Grimthorpe), Edmund Beckett, Baron
SUBJECT AREA: Horology[br]b. 12 May 1816 Newark, Nottinghamshire, Englandd. 29 April 1905 St Albans, Hertfordshire, England[br]English lawyer and amateur horologist who was the first successfully to apply the gravity escapement to public clocks.[br]Born Edmund Beckett Denison, he was educated at Eton and Trinity College, Cambridge, where he studied mathematics, graduating in 1838. He was called to the Bar in 1841 and became a Queen's Counsel in 1854. He built up a large and lucrative practice which gave him the independence to pursue his many interests outside law. His interest in horology may have been stimulated by a friend and fellow lawyer, J.M. Bloxham, who interestingly had invented a gravity escapement with an affinity to the escapement eventually used by Denison. Denison studied horology with his usual thoroughness and by 1850 he had published his Rudimentary Treatise on Clock and Watchmaking. It was natural, therefore, that he should have been invited to be a referee when a disagreement arose over the design of the clock for the new Houses of Parliament. Typically, he interpreted his brief very liberally and designed the clock himself. The most distinctive feature of the clock, in its final form, was the incorporation of a gravity escapement. A gravity escapement was particularly desirable in a public clock as it enabled the pendulum to receive a constant impulse (and thus swing with a constant amplitude), despite the variable forces that might be exerted by the wind on the exposed hands. The excellent performance of the prestigious clock at Westminster made Denison's form of gravity escapement de rigueur for large mechanical public clocks produced in Britain and in many other countries. In 1874 he inherited his father's baronetcy, dropping the Denison name, but later adopted the name Grimthorpe when he was created a Baron in 1886.[br]Principal Honours and DistinctionsPeerage 1886. President, British Horological Institute 1868–1905.BibliographyHis highly idiosyncratic A Rudimentary Treatise on Clocks and Watchmaking first published in 1850, went through eight editions, with slight changes of title, and became the most influential work in English on the subject of public clocks.Further ReadingVaudrey Mercer, 1977, The Life and Letters of Edward John Dent, London, pp. 650–1 (provides biographical information relating to horology; also contains a reliable account of Denison's involvement with the clock at Westminster).A.L.Rawlings, 1948, The Science of Clocks and Watcher, repub. 1974, pp. 98–102 (provides a technical assessment of Denison's escapement).DVBiographical history of technology > Grimthorpe (of Grimthorpe), Edmund Beckett, Baron

35 King, James Foster
SUBJECT AREA: Ports and shipping[br]b. 9 May 1862 Erskine, Scotlandd. 11 August 1947 Glasgow, Scotland[br]Scottish naval architect and classification society manager who made a significant contribution to the safety of shipping.[br]King was educated at the High School of Glasgow, and then served an apprenticeship with the Port Glasgow shipyard of Russell \& Co. This was followed by experience in drawing offices in Port Glasgow, Hull and finally in Belfast, where he was responsible for the separate White Star Line drawing office of Harland \& Wolff Ltd, which was then producing the plans for the Atlantic passenger liners Majestic and Teutonic. Following certain unpopular government shipping enactments in 1890, a protest from shipbuilders and shipowners in Ireland, Liverpool and the West of Scotland led to the founding of a new classification society to compete against Lloyd's Register of Shipping. It became known as the British Corporation Register and had headquarters in Glasgow. King was recruited to the staff and by 1903 had become Chief Surveyor, a position he held until his retirement thirty-seven years later. By then the Register was a world leader, with hundreds of thousands of tons of shipping on its books; it acted as consultant to many governments and international agencies. Throughout his working life, King did everything in his power to quantify the risks and problems of ship operation: his contribution to the Load Lines Convention of 1929 was typical, and few major enactments in shipping were designed without his approval. During the inter-war period the performance of the British Corporation outshone that of all rivals, for which King deserved full credit. His especial understanding was for steel structures, and in this respect he ensured that the British Corporation enabled owners to build ships of strengths equal to any others despite using up to 10 per cent less steel within the structure. In 1949 Lloyd's Register of Shipping and the British Corporation merged to form the largest and most influential ship classification society in the world.[br]Principal Honours and DistinctionsCBE 1920.

36 Marconi, Marchese Guglielmo
[br]b. 25 April 1874 Bologna, Italyd. 20 July 1937 Rome, Italy[br]Italian radio pioneer whose inventiveness and business skills made radio communication a practical proposition.[br]Marconi was educated in physics at Leghorn and at Bologna University. An avid experimenter, he worked in his parents' attic and, almost certainly aware of the recent work of Hertz and others, soon improved the performance of coherers and spark-gap transmitters. He also discovered for himself the use of earthing and of elevated metal plates as aerials. In 1895 he succeeded in transmitting telegraphy over a distance of 2 km (1¼ miles), but the Italian Telegraph authority rejected his invention, so in 1896 he moved to England, where he filed the first of many patents. There he gained the support of the Chief Engineer of the Post Office, and by the following year he had achieved communication across the Bristol Channel.The British Post Office was also slow to take up his work, so in 1897 he formed the Wireless Telegraph \& Signal Company to work independently. In 1898 he sold some equipment to the British Army for use in the Boer War and established the first permanent radio link from the Isle of Wight to the mainland. In 1899 he achieved communication across the English Channel (a distance of more than 31 miles or 50 km), the construction of a wireless station at Spezia, Italy, and the equipping of two US ships to report progress in the America's Cup yacht race, a venture that led to the formation of the American Marconi Company. In 1900 he won a contract from the British Admiralty to sell equipment and to train operators. Realizing that his business would be much more successful if he could offer his customers a complete radio-communication service (known today as a "turnkey" deal), he floated a new company, the Marconi International Marine Communications Company, while the old company became the Marconi Wireless Telegraph Company.His greatest achievement occurred on 12 December 1901, when Morse telegraph signals from a transmitter at Poldhu in Cornwall were received at St John's, Newfoundland, a distance of some 2,100 miles (3,400 km), with the use of an aerial flown by a kite. As a result of this, Marconi's business prospered and he became internationally famous, receiving many honours for his endeavours, including the Nobel Prize for Physics in 1909. In 1904, radio was first used to provide a daily bulletin at sea, and in 1907 a transatlantic wireless telegraphy service was inaugurated. The rescue of 1,650 passengers from the shipwreck of SS Republic in 1909 was the first of many occasions when wireless was instrumental in saving lives at sea, most notable being those from the Titanic on its maiden voyage in April 1912; more lives would have been saved had there been sufficient lifeboats. Marconi was one of those who subsequently pressed for greater safety at sea. In 1910 he demonstrated the reception of long (8 km or 5 miles) waves from Ireland in Buenos Aires, but after the First World War he began to develop the use of short waves, which were more effectively reflected by the ionosphere. By 1918 the first link between England and Australia had been established, and in 1924 he was awarded a Post Office contract for short-wave communication between England and the various parts of the British Empire.With his achievements by then recognized by the Italian Government, in 1915 he was appointed Radio-Communications Adviser to the Italian armed forces, and in 1919 he was an Italian delegate to the Paris Peace Conference. From 1921 he lived on his yacht, the Elettra, and although he joined the Fascist Party in 1923, he later had reservations about Mussolini.[br]Principal Honours and DistinctionsNobel Prize for Physics (jointly with K.F.

37 Percy, John
SUBJECT AREA: Metallurgy[br]b. 23 March 1817 Nottingham, Englandd. 19 June 1889 London, England[br]English metallurgist, first Professor of Metallurgy at the School of Mines, London.[br]After a private education, Percy went to Paris in 1834 to study medicine and to attend lectures on chemistry by Gay-Lussac and Thenard. After 1838 he studied medicine at Edinburgh, obtaining his MD in 1839. In that year he was appointed Professor of Chemistry at Queen's College, Birmingham, moving to Queen's Hospital at Birmingham in 1843. During his time at Birmingham, Percy became well known for his analysis of blast furnace slags, and was involved in the manufacture of optical glass. On 7 June 1851 Percy was appointed Metallurgical Professor and Teacher at the Museum of Practical Geology established in Jermyn Street, London, and opened in May 1851. In November of 1851, when the Museum became the Government (later Royal) School of Mines, Percy was appointed Lecturer in Metallurgy. In addition to his work at Jermyn Street, Percy lectured on metallurgy to the Advanced Class of Artillery at Woolwich from 1864 until his death, and from 1866 he was Superintendent of Ventilation at the Houses of Parliament. He served from 1861 to 1864 on the Special Committee on Iron set up to examine the performance of armour-plate in relation to its purity, composition and structure.Percy is best known for his metallurgical text books, published by John Murray. Volume I of Metallurgy, published in 1861, dealt with fuels, fireclays, copper, zinc and brass; Volume II, in 1864, dealt with iron and steel; a volume on lead appeared in 1870, followed by one on fuels and refractories in 1875, and the first volume on gold and silver in 1880. Further projected volumes on iron and steel, noble metals, and on copper, did not materialize. In 1879 Percy resigned from his School of Mines appointment in protest at the proposed move from Jermyn Street to South Kensington. The rapid growth of Percy's metallurgical collection, started in 1839, eventually forced him to move to a larger house. After his death, the collection was bought by the South Kensington (later Science) Museum. Now comprising 3,709 items, it provides a comprehensive if unselective record of nineteenth-century metallurgy, the most interesting specimens being those of the first sodium-reduced aluminium made in Britain and some of the first steel produced by Bessemer in Baxter House. Metallurgy for Percy was a technique of chemical extraction, and he has been criticized for basing his system of metallurgical instruction on this assumption. He stood strangely aloof from new processes of steel making such as that of Gilchrist and Thomas, and tended to neglect early developments in physical metallurgy, but he was the first in Britain to teach metallurgy as a discipline in its own right.[br]Principal Honours and DistinctionsFRS 1847.

38 Stephenson, George
[br]b. 9 June 1781 Wylam, Northumberland, Englandd. 12 August 1848 Tapton House, Chesterfield, England[br]English engineer, "the father of railways".[br]George Stephenson was the son of the fireman of the pumping engine at Wylam colliery, and horses drew wagons of coal along the wooden rails of the Wylam wagonway past the house in which he was born and spent his earliest childhood. While still a child he worked as a cowherd, but soon moved to working at coal pits. At 17 years of age he showed sufficient mechanical talent to be placed in charge of a new pumping engine, and had already achieved a job more responsible than that of his father. Despite his position he was still illiterate, although he subsequently learned to read and write. He was largely self-educated.In 1801 he was appointed Brakesman of the winding engine at Black Callerton pit, with responsibility for lowering the miners safely to their work. Then, about two years later, he became Brakesman of a new winding engine erected by Robert Hawthorn at Willington Quay on the Tyne. Returning collier brigs discharged ballast into wagons and the engine drew the wagons up an inclined plane to the top of "Ballast Hill" for their contents to be tipped; this was one of the earliest applications of steam power to transport, other than experimentally.In 1804 Stephenson moved to West Moor pit, Killingworth, again as Brakesman. In 1811 he demonstrated his mechanical skill by successfully modifying a new and unsatisfactory atmospheric engine, a task that had defeated the efforts of others, to enable it to pump a drowned pit clear of water. The following year he was appointed Enginewright at Killingworth, in charge of the machinery in all the collieries of the "Grand Allies", the prominent coal-owning families of Wortley, Liddell and Bowes, with authorization also to work for others. He built many stationary engines and he closely examined locomotives of John Blenkinsop's type on the Kenton \& Coxlodge wagonway, as well as those of William Hedley at Wylam.It was in 1813 that Sir Thomas Liddell requested George Stephenson to build a steam locomotive for the Killingworth wagonway: Blucher made its first trial run on 25 July 1814 and was based on Blenkinsop's locomotives, although it lacked their rack-and-pinion drive. George Stephenson is credited with building the first locomotive both to run on edge rails and be driven by adhesion, an arrangement that has been the conventional one ever since. Yet Blucher was far from perfect and over the next few years, while other engineers ignored the steam locomotive, Stephenson built a succession of them, each an improvement on the last.During this period many lives were lost in coalmines from explosions of gas ignited by miners' lamps. By observation and experiment (sometimes at great personal risk) Stephenson invented a satisfactory safety lamp, working independently of the noted scientist Sir Humphry Davy who also invented such a lamp around the same time.In 1817 George Stephenson designed his first locomotive for an outside customer, the Kilmarnock \& Troon Railway, and in 1819 he laid out the Hetton Colliery Railway in County Durham, for which his brother Robert was Resident Engineer. This was the first railway to be worked entirely without animal traction: it used inclined planes with stationary engines, self-acting inclined planes powered by gravity, and locomotives.On 19 April 1821 Stephenson was introduced to Edward Pease, one of the main promoters of the Stockton \& Darlington Railway (S \& DR), which by coincidence received its Act of Parliament the same day. George Stephenson carried out a further survey, to improve the proposed line, and in this he was assisted by his 18-year-old son, Robert Stephenson, whom he had ensured received the theoretical education which he himself lacked. It is doubtful whether either could have succeeded without the other; together they were to make the steam railway practicable.At George Stephenson's instance, much of the S \& DR was laid with wrought-iron rails recently developed by John Birkinshaw at Bedlington Ironworks, Morpeth. These were longer than cast-iron rails and were not brittle: they made a track well suited for locomotives. In June 1823 George and Robert Stephenson, with other partners, founded a firm in Newcastle upon Tyne to build locomotives and rolling stock and to do general engineering work: after its Managing Partner, the firm was called Robert Stephenson \& Co.In 1824 the promoters of the Liverpool \& Manchester Railway (L \& MR) invited George Stephenson to resurvey their proposed line in order to reduce opposition to it. William James, a wealthy land agent who had become a visionary protagonist of a national railway network and had seen Stephenson's locomotives at Killingworth, had promoted the L \& MR with some merchants of Liverpool and had carried out the first survey; however, he overreached himself in business and, shortly after the invitation to Stephenson, became bankrupt. In his own survey, however, George Stephenson lacked the assistance of his son Robert, who had left for South America, and he delegated much of the detailed work to incompetent assistants. During a devastating Parliamentary examination in the spring of 1825, much of his survey was shown to be seriously inaccurate and the L \& MR's application for an Act of Parliament was refused. The railway's promoters discharged Stephenson and had their line surveyed yet again, by C.B. Vignoles.The Stockton \& Darlington Railway was, however, triumphantly opened in the presence of vast crowds in September 1825, with Stephenson himself driving the locomotive Locomotion, which had been built at Robert Stephenson \& Co.'s Newcastle works. Once the railway was at work, horse-drawn and gravity-powered traffic shared the line with locomotives: in 1828 Stephenson invented the horse dandy, a wagon at the back of a train in which a horse could travel over the gravity-operated stretches, instead of trotting behind.Meanwhile, in May 1826, the Liverpool \& Manchester Railway had successfully obtained its Act of Parliament. Stephenson was appointed Engineer in June, and since he and Vignoles proved incompatible the latter left early in 1827. The railway was built by Stephenson and his staff, using direct labour. A considerable controversy arose c. 1828 over the motive power to be used: the traffic anticipated was too great for horses, but the performance of the reciprocal system of cable haulage developed by Benjamin Thompson appeared in many respects superior to that of contemporary locomotives. The company instituted a prize competition for a better locomotive and the Rainhill Trials were held in October 1829.Robert Stephenson had been working on improved locomotive designs since his return from America in 1827, but it was the L \& MR's Treasurer, Henry Booth, who suggested the multi-tubular boiler to George Stephenson. This was incorporated into a locomotive built by Robert Stephenson for the trials: Rocket was entered by the three men in partnership. The other principal entrants were Novelty, entered by John Braithwaite and John Ericsson, and Sans Pareil, entered by Timothy Hackworth, but only Rocket, driven by George Stephenson, met all the organizers' demands; indeed, it far surpassed them and demonstrated the practicability of the long-distance steam railway. With the opening of the Liverpool \& Manchester Railway in 1830, the age of railways began.Stephenson was active in many aspects. He advised on the construction of the Belgian State Railway, of which the Brussels-Malines section, opened in 1835, was the first all-steam railway on the European continent. In England, proposals to link the L \& MR with the Midlands had culminated in an Act of Parliament for the Grand Junction Railway in 1833: this was to run from Warrington, which was already linked to the L \& MR, to Birmingham. George Stephenson had been in charge of the surveys, and for the railway's construction he and J.U. Rastrick were initially Principal Engineers, with Stephenson's former pupil Joseph Locke under them; by 1835 both Stephenson and Rastrick had withdrawn and Locke was Engineer-in-Chief. Stephenson remained much in demand elsewhere: he was particularly associated with the construction of the North Midland Railway (Derby to Leeds) and related lines. He was active in many other places and carried out, for instance, preliminary surveys for the Chester \& Holyhead and Newcastle \& Berwick Railways, which were important links in the lines of communication between London and, respectively, Dublin and Edinburgh.He eventually retired to Tapton House, Chesterfield, overlooking the North Midland. A man who was self-made (with great success) against colossal odds, he was ever reluctant, regrettably, to give others their due credit, although in retirement, immensely wealthy and full of honour, he was still able to mingle with people of all ranks.[br]Principal Honours and DistinctionsPresident, Institution of Mechanical Engineers, on its formation in 1847.
