  • 84 Bosch, Robert August

    [br]
    b. 23 September 1861 Albeck, near Ulm, Germany
    d. 9 March 1942 Stuttgart, Germany
    [br]
    German engineer, industrialist and pioneer of internal combustion engine electrical systems.
    [br]
    Robert was the eighth of twelve children of the landlord of a hotel in the village of Albeck. He wanted to be a botanist and zoologist, but at the age of 18 he was apprenticed as a precision mechanic. He travelled widely in the south of Germany, which is unusual for an apprenticeship. In 1884, he went to the USA, where he found employment with Thomas A. Edison and his colleague, the German electrical engineer Siegmund Bergmann. During this period he became interested and involved in the rights of workers.
    In 1886 he set up his own workshop in Stuttgart, having spent a short time with Siemens in England. He built up a sound reputation for quality, but the firm outgrew its capital and in 1892 he had to sack nearly all his employees. Fortunately, among the few that he was able to retain were Arnold Zähringer, who later became Manager, and an apprentice, Gottlieb Harold. These two, under Bosch, were responsible for the development of the low-tension (1897) and the high-tension (1902) magneto. They also developed the Bosch sparking plug, again in 1902. The distributor for multi-cylinder engines followed in 1910. These developments, with a strong automotive bias, were stimulated by Bosch's association with Frederick Simms, an Englishman domiciled in Hamburg, who had become a director of Daimler in Canstatt and had secured the UK patent rights of the Daimler engine. Simms went on to invent, in about 1898, a means of varying ignition timing with low-tension magnetos.
    It must be emphasized, as pointed out above, that the invention of neither type of magneto was due to Bosch. Nikolaus Otto introduced a crude low-tension magneto in 1884, but it was not patented in Germany, while the high-tension magneto was invented by Paul Winand, a nephew of Otto's partner Eugen Langen, in 1887, this patent being allowed to lapse in 1890.
    Bosch's social views were advanced for his time. He introduced an eight-hour day in 1906 and advocated industrial arbitration and free trade, and in 1932 he wrote a book on the prevention of world economic crises, Die Verhütung künftiger Krisen in der Weltwirtschaft. Other industrialists called him the "Red Bosch" because of his short hours and high wages; he is reputed to have replied, "I do not pay good wages because I have a lot of money, I have a lot of money because I pay good wages." The firm exists to this day as the giant multi-national company Robert Bosch GmbH, with headquarters still in Stuttgart.

  • 85 Butler, Edward

    [br]
    b. 1863
    d. 1940
    [br]
    English motoring pioneer, designer of a motor tricycle.
    [br]
    In 1884 Butler patented a design for a motor tricycle that was shown that year at the Stanley Cycle Show and in the following year at the Inventions Exhibition. In 1887 he patented his "Petrol-tricycle", which was built the following year. The cycle was steered through its two front wheels, while it was driven through its single rear wheel. The motor, which was directly connected to the rear wheel hub by means of overhung cranks, consisted of a pair of water-cooled 2 1/4 in. (57 mm) bore cylinders with an 8 in. (203 mm) stroke working on the Clerk two-stroke cycle. Ignition was by electric spark produced by a wiper breaking contact with the piston, adopted from Butler's own design of electrostatic ignition machine; this was later replaced by a Ruhmkorff coil and a battery. There was insufficient power with direct drive and the low engine speed of c.100 rpm, producing a road speed of approximately 12 mph (19 km/h), so Butler redesigned the engine with a 6 3/4 in. (171 mm) stroke and a four-stroke cycle with an epicyclic reduction gear drive of 4:1 and later 6:1 ratio which could run at 600 rpm. The combination of restrictive speed-limit laws and shortsightedness of his backers prevented development, despite successful road demonstrations. Interest was non-existent by 1895, and the following year this first English internal combustion engined motorcycle was broken up for the scrap value of some 163 lb (74 kg) of copper and brass contained in its structure.

  • 86 Curtiss, Glenn Hammond

    SUBJECT AREA: Aerospace
    [br]
    b. 21 May 1878 Hammondsport, New York, USA
    d. 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]
    b. 1811 or 1812 Newcastle upon Tyne, England
    d. 4 March 1878 Cannes, France
    [br]
    English locomotive builder who built the first locomotives for the narrow-gauge Festiniog Railway.
    [br]
    England trained with John Penn \& Sons, marine engine and boilermakers, and set up his own business at Hatcham Iron Works, South London, in about 1840. This was initially a general engineering business and made traversing screw jacks, which England had patented, but by 1850 it was building locomotives. One of these, Little England, a 2–2– 2T light locomotive owing much to the ideas of W.Bridges Adams, was exhibited at the Great Exhibition of 1851, and England then prospered, supplying many railways at home and abroad with small locomotives. In 1863 he built two exceptionally small 0–4–0 tank locomotives for the Festiniog Railway, which enabled the latter's Manager and Engineer C.E. Spooner to introduce steam traction on this line with its gauge of just under 2 ft (60 cm). England's works had a reputation for good workmanship, suggesting he inspired loyalty among his employees, yet he also displayed increasingly tyrannical behaviour towards them: the culmination was a disastrous strike in 1865 that resulted in the loss of a substantial order from the South Eastern Railway. From 1866 George England became associated with development of locomotives to the patent of Robert Fairlie, but in 1869 he retired due to ill health and leased his works to a partnership of his son (also called George England), Robert Fairlie and J.S.Fraser under the title of the Fairlie Engine \& Steam Carriage Company. However, George England junior died within a few months, locomotive production ceased in 1870 and the works was sold off two years later.

    SUBJECT AREA: Textiles
    [br]
    b. 14 May 1767 Traquair, near Peebles, Scotland
    d. September 1842 London, England
    [br]
    Scottish pioneer in the mechanization of the textile industry.
    [br]
    Peter Ewart, the youngest of six sons, was born at Traquair manse, where his father was a clergyman in the Church of Scotland. He was educated at the Free School, Dumfries, and in 1782 spent a year at Edinburgh University. He followed this with an apprenticeship under John Rennie at Musselburgh before moving south in 1785 to help Rennie erect the Albion corn mill in London. This brought him into contact with Boulton \& Watt, and in 1788 he went to Birmingham to erect a waterwheel and other machinery in the Soho Manufactory. In 1789 he was sent to Manchester to install a steam engine for Peter Drinkwater and thus his long connection with the city began. In 1790 Ewart took up residence in Manchester as Boulton \& Watt's representative. Amongst other engines, he installed one for Samuel Oldknow at Stockport. In 1792 he became a partner with Oldknow in his cotton-spinning business, but because of financial difficulties he moved back to Birmingham in 1795 to help erect the machines in the new Soho Foundry. He was soon back in Manchester in partnership with Samuel Greg at Quarry Bank Mill, Styal, where he was responsible for developing the water power, installing a steam engine, and being concerned with the spinning machinery and, later, gas lighting at Greg's other mills.
    In 1798, Ewart devised an automatic expansion-gear for steam engines, but steam pressures at the time were too low for such a device to be effective. His grasp of the theory of steam power is shown by his paper to the Manchester Literary and Philosophical Society in 1808, On the Measure of Moving Force. In 1813 he patented a power loom to be worked by the pressure of steam or compressed air. In 1824 Charles Babbage consulted him about automatic looms. His interest in textiles continued until at least 1833, when he obtained a patent for a self-acting spinning mule, which was, however, outclassed by the more successful one invented by Richard Roberts. Ewart gave much help and advice to others. The development of the machine tools at Boulton \& Watt's Soho Foundry has been mentioned already. He also helped James Watt with his machine for copying sculptures. While he continued to run his own textile mill, Ewart was also in partnership with Charles Macintosh, the pioneer of rubber-coated cloth. He was involved with William Fairbairn concerning steam engines for the boats that Fairbairn was building in Manchester, and it was through Ewart that Eaton Hodgkinson was introduced to Fairbairn and so made the tests and calculations for the tubes for the Britannia Railway Bridge across the Menai Straits. Ewart was involved with the launching of the Liverpool \& Manchester Railway as he was a director of the Manchester Chamber of Commerce at the time.
    In 1835 he uprooted himself from Manchester and became the first Chief Engineer for the Royal Navy, assuming responsibility for the steamboats, which by 1837 numbered 227 in service. He set up repair facilities and planned workshops for overhauling engines at Woolwich Dockyard, the first establishment of its type. It was here that he was killed in an accident when a chain broke while he was supervising the lifting of a large boiler. Engineering was Ewart's life, and it is possible to give only a brief account of his varied interests and connections here.

  • 89 Maxim, Sir Hiram Stevens

    [br]
    b. 5 February 1840 Brockway's Mills, Maine, USA
    d. 24 November 1916 Streatham, London, England
    [br]
    American (naturalized British) inventor; designer of the first fully automatic machine gun and of an experimental steam-powered aircraft.
    [br]
    Maxim was born the son of a pioneer farmer who later became a wood turner. Young Maxim was first apprenticed to a carriage maker and then embarked on a succession of jobs before joining his uncle in his engineering firm in Massachusetts in 1864. As a young man he gained a reputation as a boxer, but it was his uncle who first identified and encouraged Hiram's latent talent for invention.
    It was not, however, until 1878, when Maxim joined the first electric-light company to be established in the USA, as its Chief Engineer, that he began to make a name for himself. He developed an improved light filament and his electric pressure regulator not only won a prize at the first International Electrical Exhibition, held in Paris in 1881, but also resulted in his being made a Chevalier de la Légion d'honneur. While in Europe he was advised that weapons development was a more lucrative field than electricity; consequently, he moved to England and established a small laboratory at Hatton Garden, London. He began by investigating improvements to the Gatling gun in order to produce a weapon with a faster rate of fire and which was more accurate. In 1883, by adapting a Winchester carbine, he successfully produced a semi-automatic weapon, which used the recoil to cock the gun automatically after firing. The following year he took this concept a stage further and produced a fully automatic belt-fed weapon. The recoil drove barrel and breechblock to the vent. The barrel then halted, while the breechblock, now unlocked from the former, continued rearwards, extracting the spent case and recocking the firing mechanism. The return spring, which it had been compressing, then drove the breechblock forward again, chambering the next round, which had been fed from the belt, as it did so. Keeping the trigger pressed enabled the gun to continue firing until the belt was expended. The Maxim gun, as it became known, was adopted by almost every army within the decade, and was to remain in service for nearly fifty years. Maxim himself joined forces with the large British armaments firm of Vickers, and the Vickers machine gun, which served the British Army during two world wars, was merely a refined version of the Maxim gun.
    Maxim's interests continued to occupy several fields of technology, including flight. In 1891 he took out a patent for a steam-powered aeroplane fitted with a pendulous gyroscopic stabilizer which would maintain the pitch of the aeroplane at any desired inclination (basically, a simple autopilot). Maxim decided to test the relationship between power, thrust and lift before moving on to stability and control. He designed a lightweight steam-engine which developed 180 hp (135 kW) and drove a propeller measuring 17 ft 10 in. (5.44 m) in diameter. He fitted two of these engines into his huge flying machine testrig, which needed a wing span of 104 ft (31.7 m) to generate enough lift to overcome a total weight of 4 tons. The machine was not designed for free flight, but ran on one set of rails with a second set to prevent it rising more than about 2 ft (61 cm). At Baldwyn's Park in Kent on 31 July 1894 the huge machine, carrying Maxim and his crew, reached a speed of 42 mph (67.6 km/h) and lifted off its rails. Unfortunately, one of the restraining axles broke and the machine was extensively damaged. Although it was subsequently repaired and further trials carried out, these experiments were very expensive. Maxim eventually abandoned the flying machine and did not develop his idea for a stabilizer, turning instead to other projects. At the age of almost 70 he returned to the problems of flight and designed a biplane with a petrol engine: it was built in 1910 but never left the ground.
    In all, Maxim registered 122 US and 149 British patents on objects ranging from mousetraps to automatic spindles. Included among them was a 1901 patent for a foot-operated suction cleaner. In 1900 he became a British subject and he was knighted the following year. He remained a larger-than-life figure, both physically and in character, until the end of his life.

    [br]
    b. 6 October 1735 (?) Halifax, Yorkshire, England
    d. 5 November 1800 Brighton, Sussex, England
    [br]
    English instrument-maker who developed machines for accurately measuring angular and linear scales.
    [br]
    Jesse Ramsden was the son of an innkeeper but received a good general education: after attending the free school at Halifax, he was sent at the age of 12 to his uncle for further study, particularly in mathematics. At the age of 16 he was apprenticed to a cloth-worker in Halifax and on completion of the apprenticeship in 1755 he moved to London to work as a clerk in a cloth warehouse. In 1758 he became an apprentice in the workshop of a London mathematical instrument-maker named Burton. He quickly gained the skill, particularly in engraving, and by 1762 he was able to set up on his own account. He married in 1765 or 1766 the youngest daughter of the optician John Dollond FRS (1706– 61) and received a share of Dollond's patent for making achromatic lenses.
    Ramsden's experience and reputation increased rapidly and he was generally regarded as the leading instrument-maker of his time. He opened a shop in the Haymarket and transferred to Piccadilly in 1775. His staff increased to about sixty workers and apprentices, and by 1789 he had constructed nearly 1,000 sextants as well as theodolites, micrometers, balances, barometers, quadrants and other instruments.
    One of Ramsden's most important contributions to precision measurement was his development of machines for obtaining accurate division of angular and linear scales. For this work he received a premium from the Commissioners of the Board of Longitude, who published his descriptions of the machines. For the trigonometrical survey of Great Britain, initiated by General William Roy FRS (1726–90) and continued by the Board of Ordnance, Ramsden supplied a 3 ft (91 cm) theodolite and steel measuring chains, and was also engaged to check the glass tubes used to measure the fundamental base line.

  • 97 Edison, Thomas Alva

    [br]
    b. 11 February 1847 Milan, Ohio, USA
    d. 18 October 1931 Glenmont
    [br]
    American inventor and pioneer electrical developer.
    [br]
    He was the son of Samuel Edison, who was in the timber business. His schooling was delayed due to scarlet fever until 1855, when he was 8½ years old, but he was an avid reader. By the age of 14 he had a job as a newsboy on the railway from Port Huron to Detroit, a distance of sixty-three miles (101 km). He worked a fourteen-hour day with a stopover of five hours, which he spent in the Detroit Free Library. He also sold sweets on the train and, later, fruit and vegetables, and was soon making a profit of $20 a week. He then started two stores in Port Huron and used a spare freight car as a laboratory. He added a hand-printing press to produce 400 copies weekly of The Grand Trunk Herald, most of which he compiled and edited himself. He set himself to learn telegraphy from the station agent at Mount Clements, whose son he had saved from being run over by a freight car.
    At the age of 16 he became a telegraphist at Port Huron. In 1863 he became railway telegraphist at the busy Stratford Junction of the Grand Trunk Railroad, arranging a clock with a notched wheel to give the hourly signal which was to prove that he was awake and at his post! He left hurriedly after failing to hold a train which was nearly involved in a head-on collision. He usually worked the night shift, allowing himself time for experiments during the day. His first invention was an arrangement of two Morse registers so that a high-speed input could be decoded at a slower speed. Moving from place to place he held many positions as a telegraphist. In Boston he invented an automatic vote recorder for Congress and patented it, but the idea was rejected. This was the first of a total of 1180 patents that he was to take out during his lifetime. After six years he resigned from the Western Union Company to devote all his time to invention, his next idea being an improved ticker-tape machine for stockbrokers. He developed a duplex telegraphy system, but this was turned down by the Western Union Company. He then moved to New York.
    Edison found accommodation in the battery room of Law's Gold Reporting Company, sleeping in the cellar, and there his repair of a broken transmitter marked him as someone of special talents. His superior soon resigned, and he was promoted with a salary of $300 a month. Western Union paid him $40,000 for the sole rights on future improvements on the duplex telegraph, and he moved to Ward Street, Newark, New Jersey, where he employed a gathering of specialist engineers. Within a year, he married one of his employees, Mary Stilwell, when she was only 16: a daughter, Marion, was born in 1872, and two sons, Thomas and William, in 1876 and 1879, respectively.
    He continued to work on the automatic telegraph, a device to send out messages faster than they could be tapped out by hand: that is, over fifty words per minute or so. An earlier machine by Alexander Bain worked at up to 400 words per minute, but was not good over long distances. Edison agreed to work on improving this feature of Bain's machine for the Automatic Telegraph Company (ATC) for $40,000. He improved it to a working speed of 500 words per minute and ran a test between Washington and New York. Hoping to sell their equipment to the Post Office in Britain, ATC sent Edison to England in 1873 to negotiate. A 500-word message was to be sent from Liverpool to London every half-hour for six hours, followed by tests on 2,200 miles (3,540 km) of cable at Greenwich. Only confused results were obtained due to induction in the cable, which lay coiled in a water tank. Edison returned to New York, where he worked on his quadruplex telegraph system, tests of which proved a success between New York and Albany in December 1874. Unfortunately, simultaneous negotiation with Western Union and ATC resulted in a lawsuit.
    Alexander Graham Bell was granted a patent for a telephone in March 1876 while Edison was still working on the same idea. His improvements allowed the device to operate over a distance of hundreds of miles instead of only a few miles. Tests were carried out over the 106 miles (170 km) between New York and Philadelphia. Edison applied for a patent on the carbon-button transmitter in April 1877, Western Union agreeing to pay him $6,000 a year for the seventeen-year duration of the patent. In these years he was also working on the development of the electric lamp and on a duplicating machine which would make up to 3,000 copies from a stencil. In 1876–7 he moved from Newark to Menlo Park, twenty-four miles (39 km) from New York on the Pennsylvania Railway, near Elizabeth. He had bought a house there around which he built the premises that would become his "inventions factory". It was there that he began the use of his 200- page pocket notebooks, each of which lasted him about two weeks, so prolific were his ideas. When he died he left 3,400 of them filled with notes and sketches.
    Late in 1877 he applied for a patent for a phonograph which was granted on 19 February 1878, and by the end of the year he had formed a company to manufacture this totally new product. At the time, Edison saw the device primarily as a business aid rather than for entertainment, rather as a dictating machine. In August 1878 he was granted a British patent. In July 1878 he tried to measure the heat from the solar corona at a solar eclipse viewed from Rawlins, Wyoming, but his "tasimeter" was too sensitive.
    Probably his greatest achievement was "The Subdivision of the Electric Light" or the "glow bulb". He tried many materials for the filament before settling on carbon. He gave a demonstration of electric light by lighting up Menlo Park and inviting the public. Edison was, of course, faced with the problem of inventing and producing all the ancillaries which go to make up the electrical system of generation and distribution-meters, fuses, insulation, switches, cabling—even generators had to be designed and built; everything was new. He started a number of manufacturing companies to produce the various components needed.
    In 1881 he built the world's largest generator, which weighed 27 tons, to light 1,200 lamps at the Paris Exhibition. It was later moved to England to be used in the world's first central power station with steam engine drive at Holborn Viaduct, London. In September 1882 he started up his Pearl Street Generating Station in New York, which led to a worldwide increase in the application of electric power, particularly for lighting. At the same time as these developments, he built a 1,300yd (1,190m) electric railway at Menlo Park.
    On 9 August 1884 his wife died of typhoid. Using his telegraphic skills, he proposed to 19-year-old Mina Miller in Morse code while in the company of others on a train. He married her in February 1885 before buying a new house and estate at West Orange, New Jersey, building a new laboratory not far away in the Orange Valley.
    Edison used direct current which was limited to around 250 volts. Alternating current was largely developed by George Westinghouse and Nicola Tesla, using transformers to step up the current to a higher voltage for long-distance transmission. The use of AC gradually overtook the Edison DC system.
    In autumn 1888 he patented a form of cinephotography, the kinetoscope, obtaining film-stock from George Eastman. In 1893 he set up the first film studio, which was pivoted so as to catch the sun, with a hinged roof which could be raised. In 1894 kinetoscope parlours with "peep shows" were starting up in cities all over America. Competition came from the Latham Brothers with a screen-projection machine, which Edison answered with his "Vitascope", shown in New York in 1896. This showed pictures with accompanying sound, but there was some difficulty with synchronization. Edison also experimented with captions at this early date.
    In 1880 he filed a patent for a magnetic ore separator, the first of nearly sixty. He bought up deposits of low-grade iron ore which had been developed in the north of New Jersey. The process was a commercial success until the discovery of iron-rich ore in Minnesota rendered it uneconomic and uncompetitive. In 1898 cement rock was discovered in New Village, west of West Orange. Edison bought the land and started cement manufacture, using kilns twice the normal length and using half as much fuel to heat them as the normal type of kiln. In 1893 he met Henry Ford, who was building his second car, at an Edison convention. This started him on the development of a battery for an electric car on which he made over 9,000 experiments. In 1903 he sold his patent for wireless telegraphy "for a song" to Guglielmo Marconi.
    In 1910 Edison designed a prefabricated concrete house. In December 1914 fire destroyed three-quarters of the West Orange plant, but it was at once rebuilt, and with the threat of war Edison started to set up his own plants for making all the chemicals that he had previously been buying from Europe, such as carbolic acid, phenol, benzol, aniline dyes, etc. He was appointed President of the Navy Consulting Board, for whom, he said, he made some forty-five inventions, "but they were pigeonholed, every one of them". Thus did Edison find that the Navy did not take kindly to civilian interference.
    In 1927 he started the Edison Botanic Research Company, founded with similar investment from Ford and Firestone with the object of finding a substitute for overseas-produced rubber. In the first year he tested no fewer than 3,327 possible plants, in the second year, over 1,400, eventually developing a variety of Golden Rod which grew to 14 ft (4.3 m) in height. However, all this effort and money was wasted, due to the discovery of synthetic rubber.
    In October 1929 he was present at Henry Ford's opening of his Dearborn Museum to celebrate the fiftieth anniversary of the incandescent lamp, including a replica of the Menlo Park laboratory. He was awarded the Congressional Gold Medal and was elected to the American Academy of Sciences. He died in 1931 at his home, Glenmont; throughout the USA, lights were dimmed temporarily on the day of his funeral.

    [br]
    A loom on which more than one ribbon could be woven at once may have been invented by Anton Möller at Danzig in 1586. It arrived in England from the Low Countries and was being used in London by 1616 and in Lancashire by 1680. Means were being devised in Switzerland c.1730 for driving these looms by power, but this was prohibited because it was feared that these looms would deprive other weavers of work. In England, a patent was taken out by John Kay of Bury and John Stell of Keighley in 1745 for improvements to these looms and it is probably that Gartside received permission to use this invention. In Manchester, Gartside set up a mill with swivel looms driven by a water-wheel; this was probably prior to 1758, because a man was brought up at the Lancaster Assizes in March of that year for threatening to burn down "the Engine House of Mr. Gartside in Manchester, Merchant". He set up his factory near Garrett Hall on the south side of Manchester and it may still have been running in 1764. However, the enterprise failed because it was necessary for each loom to be attended by one person in order to prevent any mishap occurring, and therefore it was more economic to use hand-frames, which the operatives could control more easily.

    English marine engineer and educator.
    [br]
    Sir Alexander Kennedy was trained as a marine engineer. The son of a Congregational minister, he was educated at the City of London School and the School of Mines, Jermyn Street. He was then apprenticed to J. \& W.Dudgeon of Millwall, marine engineers, and went on to become a draughtsman to Sir Charles Marsh Palmer of Jarrow (with whom he took part in the development of the compound steam-engine for marine use) and T.M.Tennant \& Co. of Leith. In 1874 he was appointed Professor of Engineering at University College, London. He built up an influential School of Engineering, being the first in England to integrate laboratory work as a regular feature of instruction. The engineering laboratory that he established in 1878 has been described as "the first of its kind in England" (Proceedings of the Institution of Civil Engineers). He and his students conducted important experiments on the strength and elasticity of materials, boiler testing and related subjects. He followed the teaching of Franz Reuleaux, whose Kinematics of Machinery he translated from the German.
    While thus breaking new educational ground at University College, Kennedy concurrently established a very thriving private practice as a consulting engineer in partnership with Bernard Maxwell Jenkin (the son of Fleeming Jenkin), to pursue which he relinquished his academic posts in 1889. He planned and installed the whole electricity system for the Westminster Electric Supply Corporation, and other electricity companies. He was also heavily involved in the development of electrically powered transport systems. During the First World War he served on a panel of the Munitions Invention Department, and after the war he undertook to record photographically the scenes of desolation in his book From Ypres to Verdun (1921). Towards the end of his life, he pursued his interest in archaeology with the exploration of Petra, recorded in a monograph: Petra. Its History and Monuments (1925). He also joined the Institution of Mechanical Engineers in 1879, becoming the President of that body in 1894, and he joined the Institution of Electrical Engineers in 1890. Kennedy was thus something of an engineering polymath, as well as being an outstanding engineering educationalist.

    b. 1719 Scotland
    d. 27 November 1811
    [br]
    Scottish millwright and inventor of the threshing machine.
    [br]
    The son of the millwright James Meikle, who is credited with the introduction of the winnowing machine into Britain, Andrew Meikle followed in his father's footsteps. His inventive inclinations were first turned to developing his father's idea, and together with his own son George he built and patented a double-fan winnowing machine.
    However, in the history of agricultural development Andrew Meikle is most famous for his invention of the threshing machine, patented in 1784. He had been presented with a model of a threshing mill designed by a Mr Ilderton of Northumberland, but after failing to make a full-scale machine work, he developed the concept further. He eventually built the first working threshing machine for a farmer called Stein at Kilbagio. The patent revolutionized farming practice because it displaced the back-breaking and soul-destroying labour of flailing the grain from the straw. The invention was of great value in Scotland and in northern England when the land was becoming underpopulated as a result of heavy industrialization, but it was bitterly opposed in the south of England until well into the nineteenth century. Although the introduction of the threshing machine led to the "Captain Swing" riots of the 1830s, in opposition to it, it shortly became universal.
    Meikle's provisional patent in 1785 was a natural progression of earlier attempts by other millwrights to produce such a machine. The published patent is based on power provided by a horse engine, but these threshing machines were often driven by water-wheels or even by windmills. The corn stalks were introduced into the machine where they were fed between cast-iron rollers moving quite fast against each other to beat the grain out of the ears. The power source, whether animal, water or wind, had to cause the rollers to rotate at high speed to knock the grain out of the ears. While Meikle's machine was at first designed as a fixed barn machine powered by a water-wheel or by a horse wheel, later threshing machines became mobile and were part of the rig of an agricultural contractor.
    In 1788 Meikle was awarded a patent for the invention of shuttered sails for windmills. This patent is part of the general description of the threshing machine, and whilst it was a practical application, it was superseded by the work of Thomas Cubitt.
    At the turn of the century Meikle became a manufacturer of threshing machines, building appliances that combined the threshing and winnowing principles as well as the reciprocating "straw walkers" found in subsequent threshing machines and in conventional combine harvesters to the present day. However, he made little financial gain from his invention, and a public subscription organized by the President of the Board of Agriculture, Sir John Sinclair, raised £1,500 to support him towards the end of his life.
