122 Camm, Sir Sydney
[br]b. 5 August 1893 Windsor, Berkshire, Englandd. 12 March 1966 Richmond, Surrey, England[br]English military aircraft designer.[br]He was the eldest of twelve children and his father was a journeyman carpenter, in whose footsteps Camm followed as an apprentice woodworker. He developed an early interest in aircraft, becoming a keen model maker in his early teens and taking a major role in founding a local society to this end, and in 1912 he designed and built a glider able to carry people. During the First World War he worked as a draughtsman for the aircraft firm Martinsyde, but became increasingly involved in design matters as the war progressed. In 1923 Camm was recruited by Sopwith to join his Hawker Engineering Company as Senior Draughtsman, but within two years had risen to be Chief Designer. His first important contribution was to develop a method of producing metal aircraft, using welded steel tubes, and in 1926 he designed his first significant aircraft, the Hawker Horsley torpedo-bomber, which briefly held the world long-distance record before it was snatched by Charles Lindbergh in his epic New York-Paris flight in 1927. His Hawker Hart light bomber followed in 1928, after which came his Hawker Fury fighter.By the mid-1930s Camm's reputation as a designer was such that he was able to wield significant influence on the Air Ministry when Royal Air Force (RAF) aircraft specifications were being drawn up. His outstanding contribution came, however, with the unveiling of his Hawker Hurricane in 1935. This single-seater fighter was to prove one of the backbones of the RAF during 1939–45, but during the war he also designed two other excellent fighters: the Tempest and the Typhoon. After the Second World War Camm turned to jet aircraft, producing in 1951 the Hawker Hunter fighter/ground-attack aircraft, which saw lengthy service in the RAF and many other air forces. His most revolutionary contribution was the design of the Harrier jump-jet, beginning with the P.1127 prototype in 1961, followed by the Kestrel three years later. These were private ventures, but eventually the Government saw the enormous merit in the vertical take-off and landing concept, and the Harrier came to fruition in 1967. Sadly Camm, who was on the Board of Sopwith Hawker Siddeley Group, died before the aircraft came into service. He is permanently commemorated in the Camm Memorial Hall at the RAF Museum, Hendon, London.[br]Principal Honours and DistinctionsCBE 1941. Knighted 1953.

123 Mies van der Rohe, Ludwig
SUBJECT AREA: Architecture and building[br]b. 27 March 1886 Aachen, Germanyd. 17 August 1969 Chicago, USA[br]German architect, third of the great trio of long-lived, second-generation modernists who established the international style in the inter-war years and brought it to maturity (See Jeanneret (Le Corbusier) and Gropius).[br]Mies van der Rohe was the son of a stonemason and his early constructional training came from his father. As a young man he gained experience of the modern school from study of the architecture of the earlier leaders, notably Peter Behrens, Hendrik Berlage and Frank Lloyd Wright. He commenced architectural practice in 1913 and soon after the First World War was establishing his own version of modern architecture. His building materials were always of the highest quality, of marble, stone, glass and, especially, steel. He stripped his designs of all extraneous decoration: more than any of his contemporaries he followed the theme of elegance, functionalism and an ascetic concentration on essentials. He believed that architectural design should not look backwards but should reflect the contemporary achievement of advanced technology in both its construction and the materials used, and he began early in his career to act upon these beliefs. Typical was his early concrete and glass office building of 1922, after which, more importantly, came his designs for the German Pavilion at the Barcelona Exposition of 1929. These designs included his famous Barcelona chair, made from chrome steel and leather in a geometrical design, one which has survived as a classic and is still in production. Another milestone was his Tugendhat House in Brno (1930), a long, low, rectilinear structure in glass and steel that set a pattern for many later buildings of this type. In 1930 Mies followed his colleagues as third Director of the Bauhaus, but due to the rise of National Socialism in Germany it was closed in 1933. He finally left Germany for the USA in 1937, and the following year he took up his post as Director of Architecture in Chicago at what is now known as the Illinois Institute of Technology and where he remained for twenty years. In America Mies van der Rohe continued to develop his work upon his original thesis. His buildings are always recognizable for their elegance, fine proportions, high-quality materials and clean, geometrical forms; nearly all are of glass and steel in rectangular shapes. The structure and design evolved according to the individual needs of each commission, and there were three fundamental types of design. One type was the single or grouped high-rise tower, built for apartments for the wealthy, as in his Lake Shore Drive Apartments in Chicago (1948–51), or for city-centre offices, as in his Seagram Building in New York (1954–8, with Philip Johnson) or his Chicago Federal Centre (1964). Another form was the long, low rectangle based upon the earlier Tugendhat House and seen again in the New National Gallery in Berlin (1965–8). Third, there were the grouped schemes when the commission called for buildings of varied purpose on a single, large site. Here Mies van der Rohe achieved a variety and interest in the different shapes and heights of buildings set out in spatial harmony of landscape. Some examples of this type of scheme were housing estates (Lafayette Park Housing Development in Detroit, 1955–6), while others were for educational, commercial or shopping requirements, as at the Toronto Dominion Centre (1963–9).[br]Further ReadingL.Hilbersheimer, 1956, Ludwig Mies van der Rohe, Chicago: P.Theobald.Peter Blake, 1960, Mies van der Rohe, Architecture and Structure, Penguin, Pelican.

125 Cartwright, Revd Edmund
[br]b. 24 April 1743 Marnham, Nottingham, Englandd. 30 October 1823 Hastings, Sussex, England[br]English inventor of the power loom, a combing machine and machines for making ropes, bread and bricks as well as agricultural improvements.[br]Edmund Cartwright, the fourth son of William Cartwright, was educated at Wakefield Grammar School, and went to University College, Oxford, at the age of 14. By special act of convocation in 1764, he was elected Fellow of Magdalen College. He married Alice Whitaker in 1772 and soon after was given the ecclesiastical living of Brampton in Derbyshire. In 1779 he was presented with the living of Goadby, Marwood, Leicestershire, where he wrote poems, reviewed new works, and began agricultural experiments. A visit to Matlock in the summer of 1784 introduced him to the inventions of Richard Arkwright and he asked why weaving could not be mechanized in a similar manner to spinning. This began a remarkable career of inventions.Cartwright returned home and built a loom which required two strong men to operate it. This was the first attempt in England to develop a power loom. It had a vertical warp, the reed fell with the weight of at least half a hundredweight and, to quote Gartwright's own words, "the springs which threw the shuttle were strong enough to throw a Congreive [sic] rocket" (Strickland 19.71:8—for background to the "rocket" comparison, see Congreve, Sir William). Nevertheless, it had the same three basics of weaving that still remain today in modern power looms: shedding or dividing the warp; picking or projecting the shuttle with the weft; and beating that pick of weft into place with a reed. This loom he proudly patented in 1785, and then he went to look at hand looms and was surprised to see how simply they operated. Further improvements to his own loom, covered by two more patents in 1786 and 1787, produced a machine with the more conventional horizontal layout that showed promise; however, the Manchester merchants whom he visited were not interested. He patented more improvements in 1788 as a result of the experience gained in 1786 through establishing a factory at Doncaster with power looms worked by a bull that were the ancestors of modern ones. Twenty-four looms driven by steam-power were installed in Manchester in 1791, but the mill was burned down and no one repeated the experiment. The Doncaster mill was sold in 1793, Cartwright having lost £30,000, However, in 1809 Parliament voted him £10,000 because his looms were then coming into general use.In 1789 he began working on a wool-combing machine which he patented in 1790, with further improvements in 1792. This seems to have been the earliest instance of mechanized combing. It used a circular revolving comb from which the long fibres or "top" were. carried off into a can, and a smaller cylinder-comb for teasing out short fibres or "noils", which were taken off by hand. Its output equalled that of twenty hand combers, but it was only relatively successful. It was employed in various Leicestershire and Yorkshire mills, but infringements were frequent and costly to resist. The patent was prolonged for fourteen years after 1801, but even then Cartwright did not make any profit. His 1792 patent also included a machine to make ropes with the outstanding and basic invention of the "cordelier" which he communicated to his friends, including Robert Fulton, but again it brought little financial benefit. As a result of these problems and the lack of remuneration for his inventions, Cartwright moved to London in 1796 and for a time lived in a house built with geometrical bricks of his own design.Other inventions followed fast, including a tread-wheel for cranes, metallic packing for pistons in steam-engines, and bread-making and brick-making machines, to mention but a few. He had already returned to agricultural improvements and he put forward suggestions in 1793 for a reaping machine. In 1801 he received a prize from the Board of Agriculture for an essay on husbandry, which was followed in 1803 by a silver medal for the invention of a three-furrow plough and in 1805 by a gold medal for his essay on manures. From 1801 to 1807 he ran an experimental farm on the Duke of Bedford's estates at Woburn.From 1786 until his death he was a prebendary of Lincoln. In about 1810 he bought a small farm at Hollanden near Sevenoaks, Kent, where he continued his inventions, both agricultural and general. Inventing to the last, he died at Hastings and was buried in Battle church.[br]Principal Honours and DistinctionsBoard of Agriculture Prize 1801 (for an essay on agriculture).

126 Porter, Charles Talbot
SUBJECT AREA: Steam and internal combustion engines[br]b. 18 January 1826 Auburn, New York, USAd. 1910 USA[br]American inventor of a stone dressing machine, an improved centrifugal governor and a high-speed steam engine.[br]Porter graduated from Hamilton College, New York, in 1845, read law in his father's office, and in the autumn of 1847 was admitted to the Bar. He practised for six or seven years in Rochester, New York, and then in New York City. He was drawn into engineering when aged about 30, first through a client who claimed to have invented a revolutionary type of engine and offered Porter the rights to it as payment of a debt. Having lent more money, Porter saw neither the man nor the engine again. Porter followed this with a similar experience over a patent for a stone dressing machine, except this time the machine was built. It proved to be a failure, but Porter set about redesigning it and found that it was vastly improved when it ran faster. His improved machine went into production. It was while trying to get the steam engine that drove the stone dressing machine to run more smoothly that he made a discovery that formed the basis for his subsequent work.Porter took the ordinary Watt centrifugal governor and increased the speed by a factor of about ten; although he had to reduce the size of the weights, he gained a motion that was powerful. To make the device sufficiently responsive at the right speed, he balanced the centrifugal forces by a counterweight. This prevented the weights flying outwards until the optimum speed was reached, so that the steam valves remained fully open until that point and then the weights reacted more quickly to variations in speed. He took out a patent in 1858, and its importance was quickly recognized. At first he manufactured and sold the governors himself in a specially equipped factory, because this was the only way he felt he could get sufficient accuracy to ensure a perfect action. For marine use, the counterweight was replaced by a spring.Higher speed had brought the advantage of smoother running and so he thought that the same principles could be applied to the steam engine itself, but it was to take extensive design modifications over several years before his vision was realized. In the winter of 1860–1, J.F. Allen met Porter and sketched out his idea of a new type of steam inlet valve. Porter saw the potential of this for his high-speed engine and Allen took out patents for it in 1862. The valves were driven by a new valve gear designed by Pius Fink. Porter decided to display his engine at the International Exhibition in London in 1862, but it had to be assembled on site because the parts were finished in America only just in time to be shipped to meet the deadline. Running at 150 rpm, the engine caused a sensation, but as it was non-condensing there were few orders. Porter added condensing apparatus and, after the failure of Ormerod Grierson \& Co., entered into an agreement with Joseph Whitworth to build the engines. Four were exhibited at the 1867 Paris Exposition Universelle, but Whitworth and Porter fell out and in 1868 Porter returned to America.Porter established another factory to build his engine in America, but he ran into all sorts of difficulties, both mechanical and financial. Some engines were built, and serious production was started c. 1874, but again there were further problems and Porter had to leave his firm. High-speed engines based on his designs continued to be made until after 1907 by the Southwark Foundry and Machine Company, Philadelphia, so Porter's ideas were proved viable and led to many other high-speed designs.[br]Bibliography1908, Engineering Reminiscences, New York: J.

SUBJECT AREA: Metallurgy[br]b. 31 December 1888 Thizy, Rhône, Franced. 15 August 1960 Fontenoy-aux-Roses, France[br]French metallurgist, inventor of the alloys Elinvar and Platinite and of the method of strengthening nickel-chromium alloys by a precipitate ofNi3Al which provided the basis of all later super-alloy development.[br]Soon after graduating from the Ecole des Mines at St-Etienne in 1910, Chevenard joined the Société de Commentry Fourchambault et Decazeville at their steelworks at Imphy, where he remained for the whole of his career. Imphy had for some years specialized in the production of nickel steels. From this venture emerged the first austenitic nickel-chromium steel, containing 6 per cent chromium and 22–4 per cent nickel and produced commercially in 1895. Most of the alloys required by Guillaume in his search for the low-expansion alloy Invar were made at Imphy. At the Imphy Research Laboratory, established in 1911, Chevenard conducted research into the development of specialized nickel-based alloys. His first success followed from an observation that some of the ferro-nickels were free from the low-temperature brittleness exhibited by conventional steels. To satisfy the technical requirements of Georges Claude, the French cryogenic pioneer, Chevenard was then able in 1912 to develop an alloy containing 55–60 per cent nickel, 1–3 per cent manganese and 0.2–0.4 per cent carbon. This was ductile down to −190°C, at which temperature carbon steel was very brittle.By 1916 Elinvar, a nickel-iron-chromium alloy with an elastic modulus that did not vary appreciably with changes in ambient temperature, had been identified. This found extensive use in horology and instrument manufacture, and even for the production of high-quality tuning forks. Another very popular alloy was Platinite, which had the same coefficient of thermal expansion as platinum and soda glass. It was used in considerable quantities by incandescent-lamp manufacturers for lead-in wires. Other materials developed by Chevenard at this stage to satisfy the requirements of the electrical industry included resistance alloys, base-metal thermocouple combinations, magnetically soft high-permeability alloys, and nickel-aluminium permanent magnet steels of very high coercivity which greatly improved the power and reliability of car magnetos. Thermostatic bimetals of all varieties soon became an important branch of manufacture at Imphy.During the remainder of his career at Imphy, Chevenard brilliantly elaborated the work on nickel-chromium-tungsten alloys to make stronger pressure vessels for the Haber and other chemical processes. Another famous alloy that he developed, ATV, contained 35 per cent nickel and 11 per cent chromium and was free from the problem of stress-induced cracking in steam that had hitherto inhibited the development of high-power steam turbines. Between 1912 and 1917, Chevenard recognized the harmful effects of traces of carbon on this type of alloy, and in the immediate postwar years he found efficient methods of scavenging the residual carbon by controlled additions of reactive metals. This led to the development of a range of stabilized austenitic stainless steels which were free from the problems of intercrystalline corrosion and weld decay that then caused so much difficulty to the manufacturers of chemical plant.Chevenard soon concluded that only the nickel-chromium system could provide a satisfactory basis for the subsequent development of high-temperature alloys. The first published reference to the strengthening of such materials by additions of aluminium and/or titanium occurs in his UK patent of 1929. This strengthening approach was adopted in the later wartime development in Britain of the Nimonic series of alloys, all of which depended for their high-temperature strength upon the precipitated compound Ni3Al.In 1936 he was studying the effect of what is now known as "thermal fatigue", which contributes to the eventual failure of both gas and steam turbines. He then published details of equipment for assessing the susceptibility of nickel-chromium alloys to this type of breakdown by a process of repeated quenching. Around this time he began to make systematic use of the thermo-gravimetrie balance for high-temperature oxidation studies.[br]Principal Honours and DistinctionsPresident, Société de Physique.
