121 Brown, Joseph Rogers
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 26 January 1810 Warren, Rhode Island, USAd. 23 July 1876 Isles of Shoals, New Hampshire, USA[br]American machine-tool builder and co-founder of Brown \& Sharpe.[br]Joseph Rogers Brown was the eldest son of David Brown, who was modestly established as a maker of and dealer in clocks and watches. Joseph assisted his father during school vacations and at the age of 17 left to obtain training as a machinist. In 1829 he joined his father in the manufacture of tower clocks at Pawtucket, Rhode Island, and two years later went into business for himself in Pawtucket making lathes and small tools. In 1833 he rejoined his father in Providence, Rhode Island, as a partner in the manufacture of docks, watches and surveying and mathematical instruments. David Brown retired in 1841.J.R.Brown invented and built in 1850 a linear dividing engine which was the first automatic machine for graduating rules in the United States. In 1851 he brought out the vernier calliper, the first application of a vernier scale in a workshop measuring tool. Lucian Sharpe was taken into partnership in 1853 and the firm became J.R.Brown \& Sharpe; in 1868 the firm was incorporated as the Brown \& Sharpe Manufacturing Company.In 1855 Brown invented a precision gear-cutting machine to make clock gears. The firm obtained in 1861 a contract to make Wilcox \& Gibbs sewing machines and gave up the manufacture of clocks. At about this time F.W. Howe of the Providence Tool Company arranged for Brown \& Sharpe to make a turret lathe required for the manufacture of muskets. This was basically Howe's design, but Brown added a few features, and it was the first machine tool built for sale by the Brown \& Sharpe Company. It was followed in 1862 by the universal milling machine invented by Brown initially for making twist drills. Particularly for cutting gear teeth, Brown invented in 1864 a formed milling cutter which could be sharpened without changing its profile. In 1867 the need for an instrument for checking the thickness of sheet material became apparent, and in August of that year J.R.Brown and L.Sharpe visited the Paris Exhibition and saw a micrometer calliper invented by Jean Laurent Palmer in 1848. They recognized its possibilities and with a few developments marketed it as a convenient, hand-held measuring instrument. Grinding lathes were made by Brown \& Sharpe in the early 1860s, and from 1868 a universal grinding machine was developed, with the first one being completed in 1876. The patent for this machine was granted after Brown's sudden death while on holiday.[br]Further ReadingJ.W.Roe, 1916, English and American Tool Builders, New Haven: Yale University Press; repub. 1926, New York and 1987, Bradley, Ill.: Lindsay Publications Inc.

122 Jeanneret, Charles-Edouard (Le Corbusier)
SUBJECT AREA: Architecture and building[br]b. 6 October 1887 La Chaux-de-Fonds, Switzerlandd. 27 August 1965 Cap Martin, France[br]Swiss/French architect.[br]The name of Le Corbusier is synonymous with the International style of modern architecture and city planning, one utilizing functionalist designs carried out in twentieth-century materials with modern methods of construction. Charles-Edouard Jeanneret, born in the watch-making town of La Chaux-de-Fonds in the Jura mountain region, was the son of a watch engraver and dial painter. In the years before 1918 he travelled widely, studying building in many countries. He learned about the use of reinforced concrete in the studio of Auguste Perret and about industrial construction under Peter Behrens. In 1917 he went to live in Paris and spent the rest of his life in France; in 1920 he adopted the name of Le Corbusier, one derived from that of his ancestors (Le Corbesier), and ten years later became a French citizen.Le Corbusier's long working life spanned a career divided into three distinct parts. Between 1905 and 1916 he designed a number of simple and increasingly modern houses; the years 1921 to 1940 were ones of research and debate; and the twenty years from 1945 saw the blossoming of his genius. After 1917 Le Corbusier gained a reputation in Paris as an architect of advanced originality. He was particularly interested in low-cost housing and in improving accommodation for the poor. In 1923 he published Vers une architecture, in which he planned estates of mass-produced houses where all extraneous and unnecessary features were stripped away and the houses had flat roofs and plain walls: his concept of "a machine for living in". These white boxes were lifted up on stilts, his pilotis, and double-height living space was provided internally, enclosed by large areas of factory glazing. In 1922 Le Corbusier exhibited a city plan, La Ville contemporaine, in which tall blocks made from steel and concrete were set amongst large areas of parkland, replacing the older concept of city slums with the light and air of modern living. In 1925 he published Urbanisme, further developing his socialist ideals. These constituted a major reform of the industrial-city pattern, but the ideas were not taken up at that time. The Depression years of the 1930s severely curtailed architectural activity in France. Le Corbusier designed houses for the wealthy there, but most of his work prior to 1945 was overseas: his Centrosoyus Administration Building in Moscow (1929–36) and the Ministry of Education Building in Rio de Janeiro (1943) are examples. Immediately after the end of the Second World War Le Corbusier won international fame for his Unité d'habitation theme, the first example of which was built in the boulevard Michelet in Marseille in 1947–52. His answer to the problem of accommodating large numbers of people in a small space at low cost was to construct an immense all-purpose block of pre-cast concrete slabs carried on a row of massive central supports. The Marseille Unité contains 350 apartments in eight double storeys, with a storey for shops half-way up and communal facilities on the roof. In 1950 he published Le Modular, which described a system of measurement based upon the human male figure. From this was derived a relationship of human and mathematical proportions; this concept, together with the extensive use of various forms of concrete, was fundamental to Le Corbusier's later work. In the world-famous and highly personal Pilgrimage Church of Notre Dame du Haut at Ronchamp (1950–5), Le Corbusier's work was in Expressionist form, a plastic design in massive rough-cast concrete, its interior brilliantly designed and lit. His other equally famous, though less popular, ecclesiastical commission showed a contrasting theme, of "brutalist" concrete construction with uncompromisingly stark, rectangular forms. This is the Dominican Convent of Sainte Marie de la Tourette at Eveux-sur-l'Arbresle near Lyon, begun in 1956. The interior, in particular, is carefully worked out, and the lighting, from both natural and artificial sources, is indirect, angled in many directions to illuminate vistas and planes. All surfaces are carefully sloped, the angles meticulously calculated to give optimum visual effect. The crypt, below the raised choir, is painted in bright colours and lit from ceiling oculi.One of Le Corbusier's late works, the Convent is a tour de force.[br]Principal Honours and DistinctionsHonorary Doctorate Zurich University 1933.

123 Maybach, Wilhelm
[br]b. 9 February 1846 Heilbronn, Württemberg, Germanyd. 14 December 1929 Stuttgart, Germany[br]German engineer and engine designer, inventor of the spray carburettor.[br]Orphaned at the age of 10, Maybach was destined to become one of the world's most renowned engine designers. From 1868 he was apprenticed as a draughtsman at the Briiderhaus Engineering Works in Reurlingen, where his talents were recognized by Gottlieb Daimler, who was Manager and Technical Director. Nikolaus Otto had by then developed his atmospheric engine and reorganized his company, Otto \& Langen, into Gasmotorenfabrik Deutz, of which he appointed Daimler Manager. After employment at a machine builders in Karlsruhe, in 1872 Maybach followed Daimler to Deutz where he worked as a partner on the design of high-speed engines: his engines ran at up to 900 rpm, some three times as fast as conventional engines of the time. Maybach made improvements to the timing, carburation and other features. In 1881 Daimler left the Deutz Company and set up on his own as a freelance inventor, moving with his family to Bad Cannstatt; in April 1882 Maybach joined him as Engineer and Designer to set up a partnership to develop lightweight high-speed engines suitable for vehicles. A motor cycle appeared in 1885 and a modified horse-drawn carriage was fitted with a Maybach engine in 1886. Other applications to small boats, fire-engine pumps and small locomotives quickly followed, and the Vee engine of 1890 that was fitted into the French Peugeot automobiles had a profound effect upon the new sport of motor racing. In 1895 Daimler won the first international motor race and the same year Maybach became Technical Director of the Daimler firm. In 1899 Emil Jellinek, Daimler agent in France and also Austro-Hungarian consul, required a car to compete with Panhard and Levassor, who had been victorious in the Paris-Bordeaux race; he wanted more power and a lower centre of gravity, and turned to Maybach with his requirements, the 35 hp Daimler- Simplex of 1901 being the outcome. Its performance and road holding superseded those of all others at the time; it was so successful that Jellinek immediately placed an order for thirty-six cars. His daughter's name was Mercedes, after whom, when the merger of Daimler and Benz came about, the name Mercedes-Benz was adopted.In his later years, Maybach designed the engine for the Zeppelin airships. He retired from the Daimler Company in 1907.[br]Principal Honours and DistinctionsSociety of German Engineers Grashof Medal (its highest honour). In addition to numerous medals and titles from technical institutions, Maybach was awarded an honorary doctorate from the Stuttgart Institute of Technology.Further ReadingF.Schidberger, Gottlieb Daimler, Wilhelm Maybach and Karl Benz, Stuttgart: Daimler Benz AG.1961, The Annals of Mercedes-Benz Motor Vehicles and Engines, 2nd edn, Stuttgart: Daimler Benz AG.E.Johnson, 1986, The Dawn of Motoring.KAB / IMcN -
124 Otis, Elijah Graves
SUBJECT AREA: Architecture and building[br]b. 3 August 1811 Halifax, Vermont, USAd. 8 April 1861 Yonkers, New York, USA[br]American mechanic and inventor of the safety passenger elevator.[br]Otis was educated in public schools and worked in a variety of jobs in the trucking and construction industries as well as in a machine shop, a carriage makers, a grist mill, and a saw mill and in a bedstead factory. It was when supervisor of construction of a new bedstead factory at Yonkers in 1852 that he developed the innovative safety features of an elevator that was to be the foundation of his later success. If the ropes or cables of a hoist should break, springs would force pawls on the lift cage to engage the ratcheted guide rails fitted into the sides of the shaft and so stop the lift. In 1853 he was planning to leave his job to join the California Gold Rush but representatives of two New York City firms who had seen his Safety Elevator and were impressed with the safety devices requested that he make them replicas. He purchased space in the Yonkers plant and began manufacture of the lifts. Demand was small at first until in 1854 he exhibited at the American Institute Fair in New York City with an impressive performance. Standing on top of the lift cage, he ordered the rope supporting it to be cut. The safety pawls engaged and the cage stopped its downward movement. From then on orders gradually increased and in 1857 he installed the first safety lift for passengers in the Haughtwout Store in New York City. The invention immediately became popular and started a revolution in architecture and the construction industry, leading to the design and building of skyscrapers, as previously buildings were limited to six or seven storeys, because of the stairs people had to climb. Otis patented several other devices, the most important of which was for a steam elevator which established the future of the Otis Elevator Company. He died at Yonkers in 1861, leaving his business to his sons.[br]Further ReadingScribner's and Webster's Dictionaries of Biography.IMcN / DY -
125 Sopwith, Sir Thomas (Tommy) Octave Murdoch
SUBJECT AREA: Aerospace[br]b. 18 January 1888 London, Englandd. 27 January 1989 Stockbridge, Hampshire, England[br]English aeronautical engineer and industrialist.[br]Son of a successful mining engineer, Sopwith did not shine at school and, having been turned down by the Royal Navy as a result, attended an engineering college. His first interest was motor cars and, while still in his teens, he set up a business in London with a friend in order to sell them; he also took part in races and rallies.Sopwith's interest in aviation came initially through ballooning, and in 1906 he purchased his own balloon. Four years later, inspired by the recent flights across the Channel to France and after a joy-ride at Brooklands, he bought an Avis monoplane, followed by a larger biplane, and taught himself to fly. He was awarded the Royal Aero Society's Aviator Certificate No. 31 on 21 November 1910, and he quickly distinguished himself in flying competitions on both sides of the Atlantic and started his own flying school. In his races he was ably supported by his friend Fred Sigrist, a former motor engineer. Among the people Sopwith taught to fly were an Australian, Harry Hawker, and Major Hugh Trenchard, who later became the "father" of the RAF.In 1912, depressed by the poor quality of the aircraft on trial for the British Army, Sopwith, in conjunction with Hawker and Sigrist, bought a skating rink in Kingston-upon-Thames and, assisted by Fred Sigrist, started to design and build his first aircraft, the Sopwith Hybrid. He sold this to the Royal Navy in 1913, and the following year his aviation manufacturing company became the Sopwith Aviation Company Ltd. That year a seaplane version of his Sopwith Tabloid won the Schneider Trophy in the second running of this speed competition. During 1914–18, Sopwith concentrated on producing fighters (or "scouts" as they were then called), with the Pup, the Camel, the 1½ Strutter, the Snipe and the Sopwith Triplane proving among the best in the war. He also pioneered several ideas to make flying easier for the pilot, and in 1915 he patented his adjustable tailplane and his 1 ½ Strutter was the first aircraft to be fitted with air brakes. During the four years of the First World War, Sopwith Aviation designed thirty-two different aircraft types and produced over 16,000 aircraft.The end of the First World War brought recession to the aircraft industry and in 1920 Sopwith, like many others, put his company into receivership; none the less, he immediately launched a new, smaller company with Hawker, Sigrist and V.W.Eyre, which they called the H.G. Hawker Engineering Company Ltd to avoid any confusion with the former company. He began by producing cars and motor cycles under licence, but was determined to resume aircraft production. He suffered an early blow with the death of Hawker in an air crash in 1921, but soon began supplying aircraft to the Royal Air Force again. In this he was much helped by taking on a new designer, Sydney Camm, in 1923, and during the next decade they produced a number of military aircraft types, of which the Hart light bomber and the Fury fighter, the first to exceed 200 mph (322 km/h), were the best known. In the mid-1930s Sopwith began to build a large aviation empire, acquiring first the Gloster Aircraft Company and then, in quick succession, Armstrong-Whitworth, Armstrong-Siddeley Motors Ltd and its aero-engine counterpart, and A.V.Roe, which produced Avro aircraft. Under the umbrella of the Hawker Siddeley Aircraft Company (set up in 1935) these companies produced a series of outstanding aircraft, ranging from the Hawker Hurricane, through the Avro Lancaster to the Gloster Meteor, Britain's first in-service jet aircraft, and the Hawker Typhoon, Tempest and Hunter. When Sopwith retired as Chairman of the Hawker Siddeley Group in 1963 at the age of 75, a prototype jump-jet (the P-1127) was being tested, later to become the Harrier, a for cry from the fragile biplanes of 1910.Sopwith also had a passion for yachting and came close to wresting the America's Cup from the USA in 1934 when sailing his yacht Endeavour, which incorporated a number of features years ahead of their time; his greatest regret was that he failed in his attempts to win this famous yachting trophy for Britain. After his retirement as Chairman of the Hawker Siddeley Group, he remained on the Board until 1978. The British aviation industry had been nationalized in April 1977, and Hawker Siddeley's aircraft interests merged with the British Aircraft Corporation to become British Aerospace (BAe). Nevertheless, by then the Group had built up a wide range of companies in the field of mechanical and electrical engineering, and its board conferred on Sopwith the title Founder and Life President.[br]Principal Honours and DistinctionsKnighted 1953.

126 Villard de Honnecourt
[br]b. c. 1200 Honnecourt-sur-Escaut, near Cambrai, Franced. mid-13th century (?) France[br]French architect-engineer.[br]Villard was one of the thirteenth-century architect-engineers who were responsible for the design and construction of the great Gothic cathedrals and other churches of the time. Their responsibilities covered all aspects of the work, including (in the spirit of the Roman architect Vitruvius) the invention and construction of mechanical devices. In their time, these men were highly esteemed and richly rewarded, although few of the inscriptions paying tribute to their achievements have survived. Villard stands out among them because a substantial part of his sketchbook has survived, in the form of thirty-three parchment sheets of drawings and notes, now kept in the Bibliothèque Nationale in Paris. Villard's professional career lasted roughly from 1225 to 1250. As a boy, he went to work on the building of the Cistercian monastery at Vaucelles, not far from Honnecourt, and afterwards he was apprenticed to the masons' lodge at Cambrai Cathedral, where he began copying the drawings and layouts on the tracing-house floor. All his drawings are, therefore, of the plans, elevations and sections of cathedrals. These buildings have long since been destroyed, but his drawings, perhaps among his earliest, bear witness to their architecture. He travelled widely in France and recorded features of the great works at Reims, Laon and Chartres. These include the complex system of passageways built into the fabric of a great cathedral; Villard comments that one of their purposes was "to allow circulation in case of fire".Villard was invited to Hungary and reached there c. 1235. He may have been responsible for the edifice dedicated to St Elizabeth of Hungary, canonized in 1235, at Kassa (now Košice, Slovakia). Villard probably returned to France c. 1240, at least before the Tartar invasion of Hungary in 1241.His sketchbook, which dates to c. 1235, stands as a memorial to Villard's skill as a draughtsman, a student of perspective and a mechanical engineer. He took his sketchbook with him on his travels, and used ideas from it in his work abroad. It contains architectural designs, geometrical constructions for use in building, surveying exercises and drawings for various kinds of mechanical devices, for civil or military use. He was transmitting details from the highly developed French Gothic masons to the relatively underdeveloped eastern countries. The notebooks were annotated for the use of pupils and other master masons, and the notes on geometry were obviously intended for pupils. The prize examples are the pages in the book, clearly Villard's own work, related to mechanical devices. Whilst he, like many others of the period and after, played with designs for perpetual-motion machines, he concentrated on useful devices. These included the first Western representation of a perpetualmotion machine, which at least displays a concern to derive a source of energy: this was a water-powered sawmill, with automatic feed of the timber into the mill. This has been described as the first industrial automatic power-machine to involve two motions, for it not only converts the rotary motion of the water-wheel to the reciprocating motion of the saw, but incorporates a means of keeping the log pressed against the saw. His other designs included water-wheels, watermills, the Archimedean screw and other curious devices.[br]BibliographyOf several facsimile reprints with notes there are Album de Villard de Honnecourt, 1858, ed.
