49 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 -
50 Humfrey, William
SUBJECT AREA: Metallurgy[br]b. c.1515d. 14 July 1579[br]English goldsmith and Assay Master of the Royal Mint who attempted to introduce brass production to England.[br]William Humfrey, goldsmith of the parish of St Vedast, was appointed Assay Master of the Royal Mint in 1561. At the Tower of London he assumed responsibility for the weight of silver and for production standards at a time of intense activity in recoining the debased coinage of the realm. Separation of copper from the debased silver involved liquation techniques which enabled purification of the recovered silver and copper. German co-operation in introducing these methods to England developed their interest in English copper mining, resulting in the formation of the Mines Royal Company. Shareholders in this government-led monopoly included Humfrey, whose assay of Keswick copper ore, mined with German expertise, was bitterly disputed. As a result of this dispute, Humfrey promoted the formation of a smaller monopoly, the Company of Mineral Battery Works, with plans to mine lead and especially the zinc carbonate ore, calamine, using it to introduce brassmaking and wire manufacture into England. Humfrey acquired technical assistance from further skilled German immigrants, relying particularly on Christopher Schutz of Annaberg in Saxony, who claimed experience in such matters. However, the brassmaking project set up at Tintern was abandoned by 1569 after failure to make a brass suitable for manufacturing purposes. The works changed its production to iron wire. Humfrey had meanwhile been under suspicion of embezzlement at the Tower in connection with his work there. He died intestate while involved in litigation regarding infringement of rights and privileges claimed from his introduction of new techniques in later lead-mining activities under the auspices of the Company of Mineral and Battery Works.[br]Further ReadingM.B.Donald, 1961, Elizabethan Monopolies, London: Oliver \& Boyd (the most detailed account).——1955, Elizabethan Copper, reprinted 1989, Michael Moon.JD -
51 Ives, Frederic Eugene
SUBJECT AREA: Photography, film and optics[br]b. 17 February 1856 Litchfield, Connecticut, USAd. 27 May 1937 Philadelphia, Pennsylvania, USA[br]American printer who pioneered the development of photomechanical and colour photographic processes.[br]Ives trained as a printer in Ithaca, New York, and became official photographer at Cornell University at the age of 18. His research into photomechanical processes led in 1886 to methods of making halftone reproduction of photographs using crossline screens. In 1881 he was the first to make a three-colour print from relief halftone blocks. He made significant contributions to the early development of colour photography, and from 1888 he published and marketed a number of systems for the production of additive colour photographs. He designed a beam-splitting camera in which a single lens exposed three negatives through red, green and blue filters. Black and white transparencies from these negatives were viewed in a device fitted with internal reflectors and filters, which combined the three colour separations into one full-colour image. This device was marketed in 1895 under the name Kromskop; sets of Kromograms were available commercially, and special cameras, or adaptors for conventional cameras, were available for photographers who wished to take their own colour pictures. A Lantern Kromskop was available for the projection of Kromskop pictures. Ives's system enjoyed a few years of commercial success before simpler methods of making colour photographs rendered it obsolete. Ives continued research into colour photography; his later achievements included the design, in 1915, of the Hicro process, in which a simple camera produced sets of separation negatives that could be printed as dyed transparencies in complementary colours and assembled in register on paper to produce colour prints. Later, in 1932, he introduced Polychrome, a simpler, two-colour process in which a bipack of two thin negative plates or films could be exposed in conventional cameras. Ives's interest extended into other fields, notably stereoscopy. He developed a successful parallax stereogram process in 1903, in which a three-dimensional image could be seen directly, without the use of viewing devices. In his lifetime he received many honours, and was a recipient of the Royal Photographic Society's Progress Medal in 1903 for his work in colour photography.[br]Further ReadingB.Coe, 1978, Colour Photography: The First Hundred Years, London J.S.Friedman, 1944, History of Colour Photography, Boston.

52 Jobard, Jean-Baptiste-Ambroise Marcelin
SUBJECT AREA: Mining and extraction technology[br]b. 14 May 1792 Baissey, Haute-Marne, Franced. 27 October 1861 Brussels, Belgium[br]French technologist, promoter of Belgian industry.[br]After attending schools in Langres and Dijon, Jobard worked in Groningen and Maastricht as a cadastral officer from 1811 onwards. After the Netherlands had been constituted as a new state in 1814, he became a Dutch citizen in 1815 and settled in Brussels. In 1825, when he had learned of the invention of lithography by Alois Senefelder, he retired and established a renowned lithographic workshop in Belgium, with considerable commercial profit. After the political changes which led to the separation of Belgium from the Netherlands in 1830, he devoted his activities to the progress of science and industry in this country, in the traditional idea of enlightenment. His main aim was to promote all branches of the young economy, to which he contributed with ceaseless energy. He cultivated especially the transfer of technology in many articles he wrote on his various journeys, such as to Britain, France, Germany and Switzerland, and he continued to do so when he became the Director of the Museum of Industry in Brussels in 1841, editing its Bulletin until his death. Jobard, as a member of societies for the encouragement of arts and industry in many countries, published on almost any subject and produced many inventions. Being a restless character by nature, and having, in addition, a strong attitude towards designing and constructing, he also contributed to mining technology in 1828 when he was the first European to practise successfully the Chinese method of rope drilling near Brussels.[br]Bibliography1840, Plan d'organisation du Musée de l'industrie, présenté au Ministre de l'interieur, Brussels.1844, Machines à vapeur, arrêtes et instructions, Brussels.1846, Comment la Belgique peut devenir industrielle, à propos de la Société d'exportation, Brussels.considérées comme blason de l'industrie et du commerce, dédié à la Société des inventeurs et protecteurs de l'industrie, Brussels.1855, Discours prononcé à l'assemblée des industriels réunis pour l'adoption de la marque obligatoire, Paris.Further ReadingH.Blémont, 1991, article in Dictionnaire de biographie française, Paris, pp. 676–7 (for a short account of his life).A.Siret, 1888–9, article in Biographie nationale de belgique, Vol. X, Brussels, col. 494– 500 (provides an impressive description of his restless character and a selected bibliography of his many publications.T.Tecklenburg, 1900, Handbuch der Tiefbohrkunde, 2nd edn, Vol. IV, Berlin, pp. 7–8 (contains detailed information on his method of rope drilling).WKBiographical history of technology > Jobard, Jean-Baptiste-Ambroise Marcelin

53 Sant'Elia, Antonio
SUBJECT AREA: Architecture and building[br]b. 30 April 1880 Como, Italyd. 10 October 1916 Monfalcone, Italy[br]Italian architectural designer and town planner.[br]Sant'Elia studied in Milan and in Bologna. In 1912 he began work in Milan, where he became part of the futurist movement in architecture. In the short time before the outbreak of the First World War, Sant'Elia began to create his designs for the city of the future; he was a talented draughtsman and made hundreds of imaginative drawings to illustrate his ideas.Fascinated by the possibilities of technology and by building in the USA, he was a visionary of future modern architecture. He planned cities for Italy, and in 1914 many of his drawings were shown at an exhibition of the Nuove Tendenze group in Milan. His Città Nuova was included; it envisaged electric power, skyscrapers, pedestrian precincts and traffic moving on overhead roadways at two and three different levels—a separation of pedestrian and wheeled traffic put forward by Leonardo da Vinci four centuries earlier in his sketchbooks. Sant'Elia was a socialist and developed his schemes as part of his suggestions for an ideal society.He was killed in action in 1916, but his drawings have survived and have influenced later work.[br]Further ReadingF.Tentori, 1955, Le Origini Liberty di Antonio Sant'Elia, Rome.——1955, L'Architettura Chronache e Storia, Rome.Rayner Banham, 1981, "Antonio Sant'Elia", Architectural Design.DY -
54 Stanley, Robert Crooks
[br]b. 1 August 1876 Little Falls, New Jersey, USAd. 12 February 1951 USA[br]American mining engineer and metallurgist, originator of Monel Metal[br]Robert, the son of Thomas and Ada (Crooks) Stanley, helped to finance his early training at the Stevens Institute of Technology, Hoboken, New Jersey, by working as a manual training instructor at Montclair High School. After graduating in mechanical engineering from Stevens in 1899, and as a mining engineer from the Columbia School of Mines in 1901, he accepted a two-year assignment from the S.S.White Dental Company to investigate platinum-bearing alluvial deposits in British Columbia. This introduced him to the International Nickel Company (Inco), which had been established on 29 March 1902 to amalgamate the major mining companies working the newly discovered cupro-nickel deposits at Sudbury, Ontario. Ambrose Monell, President of Inco, appointed Stanley as Assistant Superintendent of its American Nickel Works at Camden, near Philadelphia, in 1903. At the beginning of 1904 Stanley was General Superintendent of the Orford Refinery at Bayonne, New Jersey, where most of the output of the Sudbury mines was treated.Copper and nickel were separated there from the bessemerized matte by the celebrated "tops and bottoms" process introduced thirteen years previously by R.M.Thompson. It soon occurred to Stanley that such a separation was not invariably required and that, by reducing directly the mixed matte, he could obtain a natural cupronickel alloy which would be ductile, corrosion resistant, and no more expensive to produce than pure copper or nickel. His first experiment, on 30 December 1904, was completely successful. A railway wagon full of bessemerized matte, low in iron, was calcined to oxide, reduced to metal with carbon, and finally desulphurized with magnesium. Ingots cast from this alloy were successfully forged to bars which contained 68 per cent nickel, 23 per cent copper and about 1 per cent iron. The new alloy, originally named after Ambrose Monell, was soon renamed Monel to satisfy trademark requirements. A total of 300,000 ft2 (27,870 m2) of this white, corrosion-resistant alloy was used to roof the Pennsylvania Railway Station in New York, and it also found extensive applications in marine work and chemical plant. Stanley greatly increased the output of the Orford Refinery during the First World War, and shortly after becoming President of the company in 1922, he established a new Research and Development Division headed initially by A.J.Wadham and then by Paul D. Merica, who at the US Bureau of Standards had first elucidated the mechanism of age-hardening in alloys. In the mid- 1920s a nickel-ore body of unprecedented size was identified at levels between 2,000 and 3,000 ft (600 and 900 m) below the Frood Mine in Ontario. This property was owned partially by Inco and partially by the Mond Nickel Company. Efficient exploitation required the combined economic resources of both companies. They merged on 1 January 1929, when Mond became part of International Nickel. Stanley remained President of the new company until February 1949 and was Chairman from 1937 until his death.[br]Principal Honours and DistinctionsAmerican Society for Metals Gold Medal.

55 Sutton, Thomas
SUBJECT AREA: Photography, film and optics[br]b. 1819 Englandd. 1875 Jersey, Channel Islands[br]English photographer and writer on photography.[br]In 1841, while studying at Cambridge, Sutton became interested in photography and tried out the current processes, daguerreotype, calotype and cyanotype among them. He subsequently settled in Jersey, where he continued his photographic studies. In 1855 he opened a photographic printing works in Jersey, in partnership with L.-D. Blanquart- Evrard, exploiting the latter's process for producing developed positive prints. He started and edited one of the first photographic periodicals, Photographic Notes, in 1856; until its cessation in 1867, his journal presented a fresher view of the world of photography than that given by its London-based rivals. He also drew up the first dictionary of photography in 1858.In 1859 Sutton designed and patented a wideangle lens in which the space between two meniscus lenses, forming parts of a sphere and sealed in a metal rim, was filled with water; the lens so formed could cover an angle of up to 120 degrees at an aperture of f12. Sutton's design was inspired by observing the images produced by the water-filled sphere of a "snowstorm" souvenir brought home from Paris! Sutton commissioned the London camera-maker Frederick Cox to make the Panoramic camera, demonstrating the first model in January 1860; it took panoramic pictures on curved glass plates 152×381 mm in size. Cox later advertised other models in a total of four sizes. In January 1861 Sutton handed over manufacture to Andrew Ross's son Thomas Ross, who produced much-improved lenses and also cameras in three sizes. Sutton then developed the first single-lens reflex camera design, patenting it on 20 August 1961: a pivoted mirror, placed at 45 degrees inside the camera, reflected the image from the lens onto a ground glass-screen set in the top of the camera for framing and focusing. When ready, the mirror was swung up out of the way to allow light to reach the plate at the back of the camera. The design was manufactured for a few years by Thomas Ross and J.H. Dallmeyer.In 1861 James Clerk Maxwell asked Sutton to prepare a series of photographs for use in his lecture "On the theory of three primary colours", to be presented at the Royal Institution in London on 17 May 1861. Maxwell required three photographs to be taken through red, green and blue filters, which were to be printed as lantern slides and projected in superimposition through three projectors. If his theory was correct, a colour reproduction of the original subject would be produced. Sutton used liquid filters: ammoniacal copper sulphate for blue, copper chloride for the green and iron sulphocyanide for the red. A fourth exposure was made through lemon-yellow glass, but was not used in the final demonstration. A tartan ribbon in a bow was used as the subject; the wet-collodion process in current use required six seconds for the blue exposure, about twice what would have been needed without the filter. After twelve minutes no trace of image was produced through the green filter, which had to be diluted to a pale green: a twelve-minute exposure then produced a serviceable negative. Eight minutes was enough to record an image through the red filter, although since the process was sensitive only to blue light, nothing at all should have been recorded. In 1961, R.M.Evans of the Kodak Research Laboratory showed that the red liquid transmitted ultraviolet radiation, and by an extraordinary coincidence many natural red dye-stuffs reflect ultraviolet. Thus the red separation was made on the basis of non-visible radiation rather than red, but the net result was correct and the projected images did give an identifiable reproduction of the original. Sutton's photographs enabled Maxwell to establish the validity of his theory and to provide the basis upon which all subsequent methods of colour photography have been founded.JW / BC -
56 Voigtländer, Peter Wilhelm Friedrich
SUBJECT AREA: Photography, film and optics[br]b. 1812 Vienna, Austria d. 1878[br]Austrian manufacturer of the first purpose-designed photographic objective; key member of a dynasty of optical instrument makers.[br]Educated at the Polytechnic Institute in Vienna, Voigtländer travelled widely before taking over the family business in 1837. The business had been founded by Voigtländer's grandfather in 1756, and was continued by his father, Johann Friedrich, the inventor of the opera glass, and by the 1830s enjoyed one of the highest reputations in Europe. When Petzval made the calculations for the first purpose-designed photographic objective in 1840, it was inevitable that he should go to Peter Voigtländer for advice. The business went on to manufacture Petzval's lens, which was also fitted to an all-metal camera of totally original design by Voigtländer.The Petzval lens was an extraordinary commercial success and Voigtländer sold specimens all over the world. Unfortunately Petzval had no formal agreement with Voigtländer and made little financial gain from his design, a fact which was to lead to dispute and separation; the Voigtländer concern continued to prosper, however. To meet the increasing demand for his products, Peter Voigtländer built a new factory in Brunswick and closed the business in Vienna. The closure is seen by at least one commentator as the death blow to Vienna's optical industry, a field in which it was once preeminent. The Voigtländer dynasty continued long after Peter's death and the name enjoyed a reputation for high-quality photographic equipment well into the twentieth century.[br]Principal Honours and DistinctionsHereditary Peerage bestowed by the Emperor of Austria 1868.Further ReadingL.W.Sipley, 1965, Photography's Great Inventors, Philadelphia (a brief biography).
