53 Albert, Prince Consort
[br]b. 26 August 1819 The Rosenau, near Coburg, Germanyd. 14 December 1861 Windsor Castle, England[br]German/British polymath and Prince Consort to Queen Victoria.[br]Albert received a sound education in the arts and sciences, carefully designed to fit him for a role as consort to the future Queen Victoria. After their marriage in 1840, Albert threw himself into the task of establishing his position as, eventually, Prince Consort and uncrowned king of England. By his undoubted intellectual gifts, unrelenting hard work and moral rectitude, Albert moulded the British constitutional monarchy into the form it retains to this day. The purchase in 1845 of the Osborne estate in the Isle of Wight provided not only the growing royal family with a comfortable retreat from London and public life, but Albert with full scope for his abilities as architect and planner. With Thomas Cubitt, the eminent engineer and contractor, Albert erected at Osborne one of the most remarkable buildings of the nineteenth century. He went on to design the house and estate at Balmoral in Scotland, another notable creation.Albert applied his abilities as architect and planner in the promotion of such public works as the London sewer system and, in practical form, the design of cottages for workers, such as those in south London, as well as those on the royal estates. Albert's other main contribution to technology was as educationist in a broad sense. In 1847, he was elected Chancellor of Cambridge University. He was appalled at the low standards and narrow curriculum prevailing there and at Oxford. He was no mere figurehead, but took a close and active interest in the University's affairs. With his powerful influence behind them, the reforming fellows were able to force measures to raise standards and widen the curriculum to take account, in particular, of the rapid progress in the natural sciences. Albert was instrumental in ending the lethargy of centuries and laying the foundations of the modern British university system.In 1847 the Prince became Secretary of the Royal Society of Arts. With Henry Cole, the noted administrator who shared Albert's concern for the arts, he promoted a series of exhibitions under the auspices of the Society. From these grew the idea of a great exhibition of the products of the decorative and industrial arts. It was Albert who decided that its scope should be international. As Chairman of the organizing committee, by sheer hard work he drove the project through to a triumphant conclusion. The success of the Exhibition earned it a handsome profit for which Albert had found a use even before it closed. The proceeds went towards the purchase of a site in South Kensington, for which he drew up a grand scheme for a complex of museums and colleges for the education of the people in the sciences and the arts. This largely came to fruition and South Kensington today is a fitting memorial to the Prince Consort's wisdom and concern for the public good.[br]Further ReadingSir Theodore Martin, 1875–80, The Life of His Royal Highness, the Prince Consort, 5 vols, London; German edn 1876; French edn 1883 (the classic life of the Prince).R.R.James, 1983, Albert, Prince Consort: A Biography, London: Hamish Hamilton (the standard modern biography).L.R.Day, 1989, "Resources for the study of the history of technology in the Science Museum Library", IATUL Quarterly 3:122–39 (provides a short account of the rise of South Kensington and its institutions).LRD -
54 Clark, Edwin
SUBJECT AREA: Civil engineering[br]b. 7 January 1814 Marlow, Buckinghamshire, Englandd. 22 October 1894 Marlow, Buckinghamshire, England[br]English civil engineer.[br]After a basic education in mathematics, latin, French and geometry, Clark was articled to a solicitor, but he left after two years because he did not like the work. He had no permanent training otherwise, and for four years he led an idle life, becoming self-taught in the subjects that interested him. He eventually became a teacher at his old school before entering Cambridge, although he returned home after two years without taking a degree. He then toured the European continent extensively, supporting himself as best he could. He returned to England in 1839 and obtained further teaching posts. With the railway boom in progress he decided to become a surveyor and did some work on a proposed line between Oxford and Brighton.After being promised an interview with Robert Stephenson, he managed to see him in March 1846. Stephenson took a liking to Clark and asked him to investigate the strains on the Britannia Bridge tubes under various given conditions. This work so gained Stephenson's full approval that, after being entrusted with experiments and designs, Clark was appointed Resident Engineer for the Britannia Bridge across the Menai Straits. He not only completed the bridge, which was opened on 19 October 1850, but also wrote the history of its construction. After the completion of the bridge—and again without any professional experience—he was appointed Engineer-in-Chief to the Electric and International Telegraph Company. He was consulted by Captain Mark Huish of the London \& North Western Railway on a telegraphic system for the railway, and in 1853 he introduced the Block Telegraph System.Clark was engaged on the Crystal Palace and was responsible for many railway bridges in Britain and abroad. He was Engineer and part constructor of the harbour at Callao, Peru, and also of harbour works at Colón, Panama. On canal works he was contractor for the marine canal, the Morskoy Canal, in 1875 between Kronstadt and St Petersburg. His great work on canals, however, was the concept with Edward Leader Williams of the hydraulically operated barge lift at Anderton, Cheshire, linking the Weaver Navigation to the Trent \& Mersey Canal, whose water levels have a vertical separation of 50 ft (15 m). This was opened on 26 July 1875. The structure so impressed the French engineers who were faced with a bottleneck of five locks on the Neuffossée Canal south of Saint-Omer that they commissioned Clark to design a lift there. This was completed in 1878 and survives as a historic monument. The design was also adopted for four lifts on the Canal du Centre at La Louvière in Belgium, but these were not completed until after Clark's death.JHB -
55 Fabre, Henri
SUBJECT AREA: Aerospace[br]b. 29 November 1882 Marseilles, Franced. June 1984 France[br]French engineer, designer of the first seaplane, in which he made the first flight from water.[br]After obtaining a degree in engineering, Fabre specialized in hydrodynamics. Around 1904 he developed an interest in flying and followed the progress of early French aviators such as Archdeacon, Voisin and Blériot who were experimenting with float-gliders. Fabre carried out many experiments during the following years, including airflow tests on various surfaces and hydrodynamic tests on different designs for floats. He also built a propeller-driven motor car to develop the most efficient design for a propeller. In 1909 he built his first "hydro-aeroplane", but it failed to fly. By March 1910 he built a new float plane which was very different from contemporary French aeroplanes. It was a tail-first (canard) monoplane and had unusual Warren girder spars exposed to the airstream. The engine was a conventional Gnome rotary mounted at the rear of the machine. On 28 March 1910 Fabre, who had no previous experience of flying, decided he was ready to test his hydro-aeroplane. First he made several straight runs to test the planing properties of his three floats, then he made several short hops. In the afternoon Fabre took off from the harbour at La Mède near Marseille before official witnesses: he was able to claim the first flight by a powered seaplane. His hydro-aeroplane is preserved in the Musée de l'Air et de l'Espace in Paris.Despite several accidents, Fabre continued to improve his design and in October of 1910 Glenn Curtiss, the American designer, visited Fabre to compare notes. A year later Curtiss built the first of his many successful seaplanes. Fabre did not continue as an aircraft designer, but he went on to design and manufacture floats for other people.[br]Bibliography1980, J'ai vu naître l'aviation, Grenoble (autobiography).JDS -
56 Gurney, Sir Goldsworthy
SUBJECT AREA: Automotive engineering, Land transport, Mining and extraction technology, Steam and internal combustion engines[br]b. 14 February 1793 Treator, near Padstow, Cornwall, Englandd. 28 February 1875 Reeds, near Bude, Cornwall, England[br]English pioneer of steam road transport.[br]Educated at Truro Grammar School, he then studied under Dr Avery at Wadebridge to become a doctor of medicine. He settled as a surgeon in Wadebridge, spending his leisure time in building an organ and in the study of chemistry and mechanical science. He married Elizabeth Symons in 1814, and in 1820 moved with his wife to London. He delivered a course of lectures at the Surrey Institution on the elements of chemical science, attended by, amongst others, the young Michael Faraday. While there, Gurney made his first invention, the oxyhydrogen blowpipe. For this he received the Gold Medal of the Society of Arts. He experimented with lime and magnesia for the production of an illuminant for lighthouses with some success. He invented a musical instrument of glasses played like a piano.In 1823 he started experiments related to steam and locomotion which necessitated taking a partner in to his medical practice, from which he resigned shortly after. His objective was to produce a steam-driven vehicle to run on common roads. His invention of the steam-jet of blast greatly improved the performance of the steam engine. In 1827 he took his steam carriage to Cyfarthfa at the request of Mr Crawshaw, and while there applied his steam-jet to the blast furnaces, greatly improving their performance in the manufacture of iron. Much of the success of George Stephenson's steam engine, the Rocket was due to Gurney's steam blast.In July 1829 Gurney made a historic trip with his road locomotive. This was from London to Bath and back, which was accomplished at a speed of 18 mph (29 km/h) and was made at the instigation of the Quartermaster-General of the Army. So successful was the carriage that Sir Charles Dance started to run a regular service with it between Gloucester and Cheltenham. This ran for three months without accident, until Parliament introduced prohibitive taxation on all self-propelled vehicles. A House of Commons committee proposed that these should be abolished as inhibiting progress, but this was not done. Sir Goldsworthy petitioned Parliament on the harm being done to him, but nothing was done and the coming of the railways put the matter beyond consideration. He devoted his time to finding other uses for the steam-jet: it was used for extinguishing fires in coal-mines, some of which had been burning for many years; he developed a stove for the production of gas from oil and other fatty substances, intended for lighthouses; he was responsible for the heating and the lighting of both the old and the new Houses of Parliament.

57 Halske, Johann Georg
[br]b. 30 July 1814 Hamburg, Germanyd. 18 March 1890 Berlin, Germany[br]German engineer who introduced precision methods into the manufacture of electrical equipment; co-founder of Siemens \& Halske.[br]Halske moved to Berlin when he was a young man, and in 1844 was working for the university, at first independently and then jointly with F. Bötticher, developing and building electric medical appliances. In 1845 he met Werner von Siemens and together they became founder members of the Berlin Physics Society. It was in Halske's workshop that Siemens, assisted by the skill of the former, was able to work out his inventions in telegraphy. In 1847 the two men entered into partnership to manufacture telegraph equipment, laying the foundations of the successful firm of Siemens \& Halske. At the outset, before Werner von Siemens gave up his army career, Halske acted as the sole manager of the firm and was also involved in testing the products. Inventions they developed included electric measuring instruments and railway signalling equipment, and they installed many telegraph lines, notably those for the Russian Government. When gutta-percha became available on the market, the two men soon developed an extrusion process for applying this new material to copper conductors. To the disappointment of Halske, who was opposed to mass production, the firm introduced series production and piece wages in 1857. The expansion of the business, particularly into submarine cable laying, caused some anxiety to Halske, who left the firm on amicable terms in 1867. He then worked for a few years developing the Arts and Crafts Museum in Berlin and became a town councillor.[br]Further ReadingS. von Weihr and H.Götzeler, 1983, The Siemens Company.

58 Jenkins, Charles Francis
[br]b. 1867 USAd. 1934 USA[br]American pioneer of motion pictures and television.[br]During the early years of the motion picture industry, Jenkins made many innovations, including the development in 1894 of his own projector, the "Phantoscope", which was widely used for a number of years. In the same year he also suggested the possibility of electrically transmitting pictures over a distance, an interest that led to a lifetime of experimentation. As a result of his engineering contributions to the practical realization of moving pictures, in 1915 the National Motion Picture Board of Trade asked him to chair a committee charged with establishing technical standards for the industry. This in turn led to his proposing the creation of a professional society for those engineers in the industry, and the following year the Society of Motion Picture Engineers (later to become the Society of Motion Picture and Television Engineers) was formed, with Jenkins as its first President. Soon after this he began experiments with mechanical television, using both the Nipkow hole-spiral disc and a low-definition system of his own, based on rotating bevelled glass discs (his so-called "prismatic rings") and alkali-metal photocells. In the 1920s he gave many demonstrations of mechanical television, including a cable transmission of a crude silhouette of President Harding from Washington, DC, to Philadelphia in 1923 and a radio broadcast from Washington in 1928. The following year he formed the Jenkins Television Company to make television transmitters and receivers, but it soon went into debt and was acquired by the de Forest Company, from whom RCA later purchased the patents.[br]Principal Honours and DistinctionsFirst President, Society of Motion Picture Engineers 1916.Bibliography1923, "Radio photographs, radio movies and radio vision", Transactions of the Society of Motion Picture Engineers 16:78.1923, "Recent progress in the transmission of motion pictures by radio", Transactions ofthe Society of Motion Picture Engineers 17:81.1925, "Radio movies", Transactions of the Society of Motion Picture Engineers 21:7. 1930, "Television systems", Journal of the Society of Motion Picture Engineers 15:445. 1925.

59 Merritt, William Hamilton
[br]b. 3 July 1793 Bedford, Winchester County, New York, USAd. 5 July 1862 aboard a vessel on the Cornwall Canal, Canada[br]American-born Canadian merchant, entrepreneur and promoter of the First and Second Welland Canals bypassing the Niagara Falls and linking Lakes Ontario and Erie.[br]Although he was born in the USA, his family moved to Canada in 1796. Educated in St Catharines and Niagara, he received a good training in mathematics, navigation and surveying. He served with distinction in the 1812–14 war, although he was captured by the Americans in 1814. After the war he established himself in business operating a sawmill, a flour mill, a small distillery, a potashery, a cooperage and a smithy, as well as running a general store. By 1818 he was one of the leading figures in the area and realized that for real economic progress it was essential to improve communications in the Niagara peninsula; in that year he surveyed a route for a waterway that would carry boats.In c. 1820 he began discussions with neighbouring landowners and businessmen, who, on 19 January 1824 together obtained a charter for building the first Welland Canal to link Lakes Ontario and Erie. They were greatly influenced by the realization that the completion of the Erie Canal would attract trade through the United States instead of through Canada. Construction began on 30 November 1824, largely with redundant labour from the Erie Canal. Merritt foresaw the need for financial support and for publicity to sustain interest in the project. Accordingly he started a newspaper, the Farmer's Journal and Welland Canal Intelligencer, which was published until 1835. He also visited York (now Toronto), the capital of Upper Canada, and obtained some support, but the Government was reluctant to assist financially. He was more successful in raising money in New York. Then in 1828 he visited England to see Telford and persuaded both Telford and the Duke of Wellington, among others, to purchase shares. The Canal opened on 30 November 1829. In 1832 Merritt became a member of the Legislative Assembly of Upper Canada, and after the Union of the Canadas in 1841 he was elected to the new Assembly, later serving as Minister of Public Works and then as President of the Assembly. He advocated improvements to the St Lawrence River and also promoted railways. He pioneered a bridge across the Niagara River that was opened in 1849 and later carried a railway. He was not a canal engineer, but he did pioneer communications in developing territory.[br]Further ReadingR.M.Styran and R.R.Taylor, 1988, The Welland Canals.

60 Norton, Charles Hotchkiss
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 23 November 1851 Plainville, Connecticut, USAd. 27 October 1942 Plainville, Connecticut, USA[br]American mechanical engineer and machine-tool designer.[br]After an elementary education at the public schools of Plainville and Thomaston, Connecticut, Charles H.Norton started work in 1866 at the Seth Thomas Clock Company in Thomaston. He was soon promoted to machinist, and further progress led to his successive appointments as Foreman, Superintendent of Machinery and Manager of the department making tower clocks. He designed many public clocks.In 1886 he obtained a position as Assistant Engineer with the Brown \& Sharpe Manufacturing Company at Providence, Rhode Island, and was engaged in redesigning their universal grinding machine to give it more rigidity and make it more suitable for use as a production machine. In 1890 he left to become a partner in a newly established firm, Leland, Faulconer \& Norton Company at Detroit, Michigan, designing and building machine tools. He withdrew from this firm in 1895 and practised as a consulting mechanical engineer for a short time before returning to Brown \& Sharpe in 1896. There he designed a grinding machine incorporating larger and wider grinding wheels so that heavier cuts could be made to meet the needs of the mass-production industries, especially the automobile industry. This required a heavier and more rigid machine and greater power, but these ideas were not welcomed at Brown \& Sharpe and in 1900 Norton left to found the Norton Grinding Company in Worcester, Massachusetts. Here he was able to develop heavy-production grinding machines, including special machines for grinding crank-shafts and camshafts for the automobile industry.In setting up the Norton Grinding Company, Charles H.Norton received financial support from members of the Norton Emery Wheel Company (also of Worcester and known after 1906 as the Norton Company), but he was not related to the founder of that company. The two firms were completely independent until 1919 when they were merged. From that time Charles H.Norton served as Chief Engineer of the machinery division of the Norton Company, until 1934 when he became their Consulting Engineer.[br]Principal Honours and DistinctionsCity of Philadelphia, John Scott Medal 1925.BibliographyNorton was granted more than one hundred patents and was author of Principles of Cylindrical Grinding, 1917, 1921, Worcester, Mass.Further ReadingRobert S.Woodbury, 1959, History of the Grinding Machine, Cambridge, Mass, (contains biographical information and details of the machines designed by Norton).RTSBiographical history of technology > Norton, Charles Hotchkiss
