3 Sperry, Elmer Ambrose
[br]b. 21 October 1860 Cincinnatus, Cortland County, New York, USAd. 16 June 1930 Brooklyn, New York, USA[br]American entrepreneur who invented the gyrocompass.[br]Sperry was born into a farming community in Cortland County. He received a rudimentary education at the local school, but an interest in mechanical devices was aroused by the agricultural machinery he saw around him. His attendance at the Normal School in Cortland provided a useful theoretical background to his practical knowledge. He emerged in 1880 with an urge to pursue invention in electrical engineering, then a new and growing branch of technology. Within two years he was able to patent and demonstrate his arc lighting system, complete with its own generator, incorporating new methods of regulating its output. The Sperry Electric Light, Motor and Car Brake Company was set up to make and market the system, but it was difficult to keep pace with electric-lighting developments such as the incandescent lamp and alternating current, and the company ceased in 1887 and was replaced by the Sperry Electric Company, which itself was taken over by the General Electric Company.In the 1890s Sperry made useful inventions in electric mining machinery and then in electric street-or tramcars, with his patent electric brake and control system. The patents for the brake were important enough to be bought by General Electric. From 1894 to 1900 he was manufacturing electric motor cars of his own design, and in 1900 he set up a laboratory in Washington, where he pursued various electrochemical processes.In 1896 he began to work on the practical application of the principle of the gyroscope, where Sperry achieved his most notable inventions, the first of which was the gyrostabilizer for ships. The relatively narrow-hulled steamship rolled badly in heavy seas and in 1904 Ernst Otto Schuck, a German naval engineer, and Louis Brennan in England began experiments to correct this; their work stimulated Sperry to develop his own device. In 1908 he patented the active gyrostabilizer, which acted to correct a ship's roll as soon as it started. Three years later the US Navy agreed to try it on a destroyer, the USS Worden. The successful trials of the following year led to widespread adoption. Meanwhile, in 1910, Sperry set up the Sperry Gyroscope Company to extend the application to commercial shipping.At the same time, Sperry was working to apply the gyroscope principle to the ship's compass. The magnetic compass had worked well in wooden ships, but iron hulls and electrical machinery confused it. The great powers' race to build up their navies instigated an urgent search for a solution. In Germany, Anschütz-Kämpfe (1872–1931) in 1903 tested a form of gyrocompass and was encouraged by the authorities to demonstrate the device on the German flagship, the Deutschland. Its success led Sperry to develop his own version: fortunately for him, the US Navy preferred a home-grown product to a German one and gave Sperry all the backing he needed. A successful trial on a destroyer led to widespread acceptance in the US Navy, and Sperry was soon receiving orders from the British Admiralty and the Russian Navy.In the rapidly developing field of aeronautics, automatic stabilization was becoming an urgent need. In 1912 Sperry began work on a gyrostabilizer for aircraft. Two years later he was able to stage a spectacular demonstration of such a device at an air show near Paris.Sperry continued research, development and promotion in military and aviation technology almost to the last. In 1926 he sold the Sperry Gyroscope Company to enable him to devote more time to invention.[br]Principal Honours and DistinctionsJohn Fritz Medal 1927. President, American Society of Mechanical Engineers 1928.BibliographySperry filed over 400 patents, of which two can be singled out: 1908. US patent no. 434,048 (ship gyroscope); 1909. US patent no. 519,533 (ship gyrocompass set).Further ReadingT.P.Hughes, 1971, Elmer Sperry, Inventor and Engineer, Baltimore: Johns Hopkins University Press (a full and well-documented biography, with lists of his patents and published writings).LRD -
4 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.

5 Du Cane, Peter
SUBJECT AREA: Ports and shipping[br]b. Englandd. 31 October 1984[br]English engineer, one of the foremost designers of small high-speed ships.[br]Peter Du Cane was appointed a midshipman in the Royal Navy in 1913, having commenced as a cadet at the tender age of 13. At the end of the First World War he transferred to the engineering branch and was posted ultimately to the Yangtze River gunboat fleet. In 1928 he resigned, trained as a pilot and then joined the shipbuilders Vosper Ltd of Portsmouth. For thirty-five years he held the posts of Managing Director and Chief Designer, developing the company's expertise in high-speed, small warships, pleasure craft and record breakers. During the Second World War the company designed and built many motor torpedo-boats, air-sea rescue craft and similar ships. Du Cane served for some months in the Navy, but at the request of the Government he returned to his post in the shipyard. The most glamorous products of the yard were the record breakers Bluebird II, with which Malcolm Campbell took the world water speed record in 1939, and the later Crusader, in which John Cobb lost his life. Despite this blow the company went from strength to strength, producing the epic Brave class fast patrol craft for the Royal Navy, which led to export orders. In 1966 the yard merged with John I.Thornycroft Ltd. Commander Du Cane retired seven years later.[br]Principal Honours and DistinctionsCommander of the Royal Navy.

7 Issigonis, Sir Alexander Arnold Constantine (Alec)
[br]b. 18 November 1906 Smyrna (now Izmir), Turkeyd. 2 October 1988 Birmingham, England[br]British automobile designer whose work included the Morris Minor and the Mini series.[br]His father was of Greek descent but was a naturalized British subject in Turkey who ran a marine engineering business. After the First World War, the British in Turkey were evacuated by the Royal Navy, the Issigonis family among them. His father died en route in Malta, but the rest of the family arrived in England in 1922. Alec studied engineering at Battersea Polytechnic for three years and in 1928 was employed as a draughtsman by a firm of consulting engineers in Victoria Street who were working on a form of automatic transmission. He had occasion to travel frequently in the Midlands at this time and visited many factories in the automobile industry. He was offered a job in the drawing office at Humber and lived for a couple of years in Kenilworth. While there he met Robert Boyle, Chief Engineer of Morris Motors (see Morris, William Richard), who offered him a job at Cowley. There he worked at first on the design of independent front suspension. At Morris Motors, he designed the Morris Minor, which entered production in 1948 and continued to be manufactured until 1971. Issigonis disliked mergers, and after the merger of Morris with Austin to form the British Motor Corporation (BMC) he left to join Alvis in 1952. The car he designed there, a V8 saloon, was built as a prototype but was never put into production. Following his return to BMC to become Technical Director in 1955, his most celebrated design was the Mini series, which entered production in 1959. This was a radically new concept: it was unique for its combination of a transversely mounted engine in unit with the gearbox, front wheel drive and rubber suspension system. This suspension system, designed in cooperation with Alex Moulton, was also a fundamental innovation, developed from the system designed by Moulton for the earlier Alvis prototype. Issigonis remained as Technical Director of BMC until his retirement.[br]Further ReadingPeter King, 1989, The Motor Men.

8 Mavor, Henry Alexander
[br]b. 1858 Stranraer, Scotlandd. 16 July 1915 Mauchline, Ayrshire, Scotland[br]Scottish engineer who pioneered the use of electricity for lighting, power and the propulsion of ships.[br]Mavor came from a distinguished Scottish family with connections in medicine, industry and the arts. On completion of his education at Glasgow University, he joined R.J.Crompton \& Co.; then in 1883, along with William C.Muir, he established the Glasgow firm which later became well known as Mavor and Coulson. It pioneered the supply of electricity to public undertakings and equipped the first two generating stations in Scotland. Mavor and his fellow directors appreciated the potential demand by industry in Glasgow for electricity. Two industries were especially well served; first, the coal-mines, where electric lighting and power transformed efficiency and safety beyond recognition; and second, marine engineering. Here Mavor recognized the importance of the variable-speed motor in working with marine propellers which have a tighter range of efficient working speeds. In 1911 he built a 50 ft (15 m) motor launch, appropriately named Electric Arc, at Dumbarton and fitted it with an alternating-current motor driven by a petrol engine and dynamo. Within two years British shipyards were building electrically powered ships, and by the beginning of the First World War the United States Navy had a 20,000-ton collier with this new form of propulsion.[br]Principal Honours and DistinctionsVice-President, Institution of Engineers and Shipbuilders in Scotland 1894–6.BibliographyMavor published several papers on electric power supply, distribution and the use of electricity for marine purposes in the Transactions of the Institution of Engineers and Shipbuilders in Scotland between the years 1890 and 1912.Further ReadingMavor and Coulson Ltd, 1911, Electric Propulsion of Ships, Glasgow.FMW -
9 Sprague, Frank Julian
[br]b. 25 July 1857 Milford, Connecticut, USAd. 25 October 1934 New York, USA[br]American electrical engineer and inventor, a leading innovator in electric propulsion systems for urban transport.[br]Graduating from the United States Naval Academy, Annapolis, in 1878, Sprague served at sea and with various shore establishments. In 1883 he resigned from the Navy and obtained employment with the Edison Company; but being convinced that the use of electricity for motive power was as important as that for illumination, in 1884 he founded the Sprague Electric Railway and Motor Company. Sprague began to develop reliable and efficient motors in large sizes, marketing 15 hp (11 kW) examples by 1885. He devised the method of collecting current by using a wooden, spring-loaded rod to press a roller against the underside of an overhead wire. The installation by Sprague in 1888 of a street tramway on a large scale in Richmond, Virginia, was to become the prototype of the universally adopted trolley system with overhead conductor and the beginning of commercial electric traction. Following the success of the Richmond tramway the company equipped sixty-seven other railways before its merger with Edison General Electric in 1890. The Sprague traction motor supported on the axle of electric streetcars and flexibly mounted to the bogie set a pattern that was widely adopted for many years.Encouraged by successful experiments with multiple-sheave electric elevators, the Sprague Elevator Company was formed and installed the first set of high-speed passenger cars in 1893–4. These effectively displaced hydraulic elevators in larger buildings. From experience with control systems for these, he developed his system of multiple-unit control for electric trains, which other engineers had considered impracticable. In Sprague's system, a master controller situated in the driver's cab operated electrically at a distance the contactors and reversers which controlled the motors distributed down the train. After years of experiment, Sprague's multiple-unit control was put into use for the first time in 1898 by the Chicago South Side Elevated Railway: within fifteen years multiple-unit operation was used worldwide.[br]Principal Honours and DistinctionsPresident, American Institute of Electrical Engineers 1892–3.

11 Booth, Hubert Cecil
SUBJECT AREA: Civil engineering, Domestic appliances and interiors, Mechanical, pneumatic and hydraulic engineering, Ports and shipping[br]b. 1871 Gloucester, England d. 1955[br]English mechanical, civil and construction engineer best remembered as the inventor of the vacuum cleaner.[br]As an engineer Booth contributed to the design of engines for Royal Navy battleships, designed and supervised the erection of a number of great wheels (in Blackpool, Vienna and Paris) and later designed factories and bridges.In 1900 he attended a demonstration, at St Paneras Station in London, of a new form of railway carriage cleaner that was supposed to blow the dirt into a container. It was not a very successful experiment and Booth, having considered the problem carefully, decided that sucking might be better than blowing. He tried out his idea by placing a piece of damp cloth over an upholstered armchair. When he sucked air by mouth through his cloth the dirt upon it was tangible proof of his theory.Various attempts were being made at this time, especially in America, to find a successful cleaner of carpets and upholstery. Booth produced the first truly satisfactory machine, which he patented in 1901, and coined the term "vacuum cleaner". He formed the Vacuum Cleaner Co. (later to become Goblin BVC Ltd) and began to manufacture his machines. For some years the company provided a cleaning service to town houses, using a large and costly vacuum cleaner (the first model cost £350). Painted scarlet, it measured 54×10×42 in. (137×25×110 cm) and was powered by a petrol-driven 5 hp piston engine. It was transported through the streets on a horse-driven van and was handled by a team of operators who parked outside the house to be cleaned. With the aid of several hundred feet of flexible hose extending from the cleaner through the windows into all the rooms, the machine sucked the dirt of decades from the carpets; at the first cleaning the weight of many such carpets was reduced by 50 per cent as the dirt was sucked away.Many attempts were made in Europe and America to produce a smaller and less expensive machine. Booth himself designed the chief British model in 1906, the Trolley- Vac, which was wheeled around the house on a trolley. Still elaborate, expensive and heavy, this machine could, however, be operated inside a room and was powered from an electric light fitting. It consisted of a sophisticated electric motor and a belt-driven rotary vacuum pump. Various hoses and fitments made possible the cleaning of many different surfaces and the dust was trapped in a cloth filter within a small metal canister. It was a superb vacuum cleaner but cost 35 guineas and weighed a hundredweight (50 kg), so it was difficult to take upstairs.Various alternative machines that were cheaper and lighter were devised, but none was truly efficient until a prototype that married a small electric motor to the machine was produced in 1907 in America.[br]Further ReadingThe Story of the World's First Vacuum Cleaner, Leatherhead: BSR (Housewares) Ltd.

12 Curtiss, Glenn Hammond
SUBJECT AREA: Aerospace[br]b. 21 May 1878 Hammondsport, New York, USAd. 23 July 1930 Buffalo, New York, USA[br]American designer of aeroplanes, especially seaplanes.[br]Curtiss started his career in the bicycle business, then became a designer of motor-cycle engines, and in 1904 he designed and built an airship engine. The success of his engine led to him joining the Aerial Experimental Association (AEA), founded by the inventor Alexander Graham Bell. Working with the AEA, Curtiss built several engines and designed a biplane, June Bug, in which he won a prize for the first recorded flight of over 1 km (1,100yd) in the USA. In 1909 Curtiss joined forces with Augustus M.Herring, who had earlier flown Octave Chanute's gliders, to form the Herring-Curtiss Company. Their Gold Bug was a success and led to the Golden Flyer, in which Glenn Curtiss won the Gordon Bennett Cup at Rheims in France with a speed of 75.7 km/h (47 mph). At this time the Wright brothers accused Curtiss and the new Curtiss Aeroplane Company of infringing their patent rights, and a bitter lawsuit ensued. The acrimony subsided during the First World War and in 1929 the two companies merged to form the Curtiss-Wright Corporation.Curtiss had started experimenting with water-based aircraft in 1908, but it was not until 1911 that he managed to produce a successful float-plane. He then co-operated with the US Navy in developing catapults to launch aircraft from ships at sea. During the First World War, Curtiss produced the JN-4 Jenny trainer, which became probably his best-known design. This sturdy bi-plane continued in service long after the war and was extensively used by "barnstorming" pilots at air shows and for early mail flights. In 1919 a Navy-Curtiss NC-4 flying boat achieved the first flight across the Atlantic, having made the crossing in stages, refuelling en route. Curtiss himself, however, had little interest in aviation in his later years and turned his attention to real-estate development in Florida.[br]Principal Honours and DistinctionsRobert J.Collier Trophy 1911, 1912.

13 Cousteau, Jacques-Yves
SUBJECT AREA: Ports and shipping[br]b. 11 June 1910 Saint-André-de-Cubzac, France[br]French marine explorer who invented the aqualung.[br]He was the son of a country lawyer who became legal advisor and travelling companion to certain rich Americans. At an early age Cousteau acquired a love of travel, of the sea and of cinematography: he made his first film at the age of 13. After an interrupted education he nevertheless passed the difficult entrance examination to the Ecole Navale in Brest, but his naval career was cut short in 1936 by injuries received in a serious motor accident. For his long recuperation he was drafted to Toulon. There he met Philippe Tailliez, a fellow naval officer, and Frédéric Dumas, a champion spearfisher, with whom he formed a long association and began to develop his underwater swimming and photography. He apparently took little part in the Second World War, but under cover he applied his photographic skills to espionage, for which he was awarded the Légion d'honneur after the war.Cousteau sought greater freedom of movement underwater and, with Emile Gagnan, who worked in the laboratory of Air Liquide, he began experimenting to improve portable underwater breathing apparatus. As a result, in 1943 they invented the aqualung. Its simple design and robust construction provided a reliable and low-cost unit and revolutionized scientific and recreational diving. Gagnan shunned publicity, but Cousteau revelled in the new freedom to explore and photograph underwater and exploited the publicity potential to the full.The Undersea Research Group was set up by the French Navy in 1944 and, based in Toulon, it provided Cousteau with the Opportunity to develop underwater exploration and filming techniques and equipment. Its first aims were minesweeping and exploration, but in 1948 Cousteau pioneered an extension to marine archaeology. In 1950 he raised the funds to acquire a surplus US-built minesweeper, which he fitted out to further his quest for exploration and adventure and named Calypso. Cousteau also sought and achieved public acclaim with the publication in 1953 of The Silent World, an account of his submarine observations, illustrated by his own brilliant photography. The book was an immediate success and was translated into twenty-two languages. In 1955 Calypso sailed through the Red Sea and the western Indian Ocean, and the outcome was a film bearing the same title as the book: it won an Oscar and the Palme d'Or at the Cannes film festival. This was his favoured medium for the expression of his ideas and observations, and a stream of films on the same theme kept his name before the public.Cousteau's fame earned him appointment by Prince Rainier as Director of the Oceanographie Institute in Monaco in 1957, a post he held until 1988. With its museum and research centre, it offered Cousteau a useful base for his worldwide activities.In the 1980s Cousteau turned again to technological development. Like others before him, he was concerned to reduce ships' fuel consumption by harnessing wind power. True to form, he raised grants from various sources to fund research and enlisted technical help, namely Lucien Malavard, Professor of Aerodynamics at the Sorbonne. Malavard designed a 44 ft (13.4 m) high non-rotating cylinder, which was fitted onto a catamaran hull, christened Moulin à vent. It was intended that its maiden Atlantic crossing in 1983 should herald a new age in ship propulsion, with large royalties to Cousteau. Unfortunately the vessel was damaged in a storm and limped to the USA under diesel power. A more robust vessel, the Alcyone, was fitted with two "Turbosails" in 1985 and proved successful, with a 40 per cent reduction in fuel consumption. However, oil prices fell, removing the incentive to fit the new device; the lucrative sales did not materialize and Alcyone remained the only vessel with Turbosails, sharing with Calypso Cousteau's voyages of adventure and exploration. In September 1995, Cousteau was among the critics of the decision by the French President Jacques Chirac to resume testing of nuclear explosive devices under the Mururoa atoll in the South Pacific.[br]Principal Honours and DistinctionsLégion d'honneur.

14 Whitehead, Robert
SUBJECT AREA: Weapons and armour[br]b. 3 January 1823 Bolton-le-Moors, Lancashire, Englandd. 19 November 1903 Shrivenham, Wiltshire, England[br]English inventor of the torpedo.[br]At the age of 14 Whitehead was apprenticed by his father, who ran a cotton-bleaching business, to an engineering firm in Manchester. He moved in 1847 to join his uncle, who was the Manager of another engineering firm, and three years later Whitehead set up on his own in Milan, where he made mechanical improvements to the silk-weaving industry and designed drainage machines for the Lombardy marshes.In 1848 he was forced to move from Italy because of the revolution and settled in Fiume, which was then part of Austria. There he concen-. trated on designing and building engines for warships, and in 1864 the Austrians invited him to participate in a project to develop a "floating torpedo". In those days the torpedo was synonymous with the underwater mine, and Whitehead believed that he could do better than this proposal and produce an explosive weapon that could propel itself through the water. He set to work with his son John and a mechanic, producing the first version of his torpedo in 1866. It had a range of only 700 yd (640 m) and a speed of just 7 knots (13 km/h), as well as depth-keeping problems, but even so, especially after he had reduced the last problem by the use of a "balance chamber", the Austrian authorities were sufficiently impressed to buy construction rights and to decorate him. Other navies quickly followed suit and within twenty years almost every navy in the world was equipped with the Whitehead torpedo, its main attraction being that no warship, however large, was safe from it. During this time Whitehead continued to improve on his design, introducing a servo-motor and gyroscope, thereby radically improving range, speed and accuracy.[br]Principal Honours and DistinctionsOrder of Max Joseph (Austria) 1868. Légion d'honneur 1884. Whitehead also received decorations from Prussia, Denmark, Portugal, Italy and Greece.Further ReadingDictionary of National Biography, 1912, Vol. 3, Suppl. 2, London: Smith, Elder.CM
