21 Leonardo da Vinci
[br]b. 15 April 1452 Vinci, near Florence, Italy,d. 2 May 1519 St Cloux, near Amboise, France.[br]Italian scientist, engineer, inventor and artist.[br]Leonardo was the illegitimate son of a Florentine lawyer. His first sixteen years were spent with the lawyer's family in the rural surroundings of Vinci, which aroused in him a lifelong love of nature and an insatiable curiosity in it. He received little formal education but extended his knowledge through private reading. That gave him only a smattering of Latin, a deficiency that was to be a hindrance throughout his active life. At sixteen he was apprenticed in the studio of Andrea del Verrochio in Florence, where he received a training not only in art but in a wide variety of crafts and technical arts.In 1482 Leonardo went to Milan, where he sought and obtained employment with Ludovico Sforza, later Duke of Milan, partly to sculpt a massive equestrian statue of Ludovico but the work never progressed beyond the full-scale model stage. He did, however, complete the painting which became known as the Virgin of the Rocks and in 1497 his greatest artistic achievement, The Last Supper, commissioned jointly by Ludovico and the friars of Santa Maria della Grazie and painted on the wall of the monastery's refectory. Leonardo was responsible for the court pageants and also devised a system of irrigation to supply water to the plains of Lombardy. In 1499 the French army entered Milan and deposed Leonardo's employer. Leonardo departed and, after a brief visit to Mantua, returned to Florence, where for a time he was employed as architect and engineer to Cesare Borgia, Duke of Romagna. Around 1504 he completed another celebrated work, the Mona Lisa.In 1506 Leonardo began his second sojourn in Milan, this time in the service of King Louis XII of France, who appointed him "painter and engineer". In 1513 Leonardo left for Rome in the company of his pupil Francesco Melzi, but his time there was unproductive and he found himself out of touch with the younger artists active there, Michelangelo above all. In 1516 he accepted with relief an invitation from King François I of France to reside at the small château of St Cloux in the royal domain of Amboise. With the pension granted by François, Leonardo lived out his remaining years in tranquility at St Cloux.Leonardo's career can hardly be regarded as a success or worthy of such a towering genius. For centuries he was known only for the handful of artistic works that he managed to complete and have survived more or less intact. His main activity remained hidden until the nineteenth and twentieth centuries, during which the contents of his notebooks were gradually revealed. It became evident that Leonardo was one of the greatest scientific investigators and inventors in the history of civilization. Throughout his working life he extended a searching curiosity over an extraordinarily wide range of subjects. The notes show careful investigation of questions of mechanical and civil engineering, such as power transmission by means of pulleys and also a form of chain belting. The notebooks record many devices, such as machines for grinding and polishing lenses, a lathe operated by treadle-crank, a rolling mill with conical rollers and a spinning machine with pinion and yard divider. Leonardo made an exhaustive study of the flight of birds, with a view to designing a flying machine, which obsessed him for many years.Leonardo recorded his observations and conclusions, together with many ingenious inventions, on thousands of pages of manuscript notes, sketches and drawings. There are occasional indications that he had in mind the publication of portions of the notes in a coherent form, but he never diverted his energy into putting them in order; instead, he went on making notes. As a result, Leonardo's impact on the development of science and technology was virtually nil. Even if his notebooks had been copied and circulated, there were daunting impediments to their understanding. Leonardo was left-handed and wrote in mirror-writing: that is, in reverse from right to left. He also used his own abbreviations and no punctuation.At his death Leonardo bequeathed his entire output of notes to his friend and companion Francesco Melzi, who kept them safe until his own death in 1570. Melzi left the collection in turn to his son Orazio, whose lack of interest in the arts and sciences resulted in a sad period of dispersal which endangered their survival, but in 1636 the bulk of them, in thirteen volumes, were assembled and donated to the Ambrosian Library in Milan. These include a large volume of notes and drawings compiled from the various portions of the notebooks and is now known as the Codex Atlanticus. There they stayed, forgotten and ignored, until 1796, when Napoleon's marauding army overran Italy and art and literary works, including the thirteen volumes of Leonardo's notebooks, were pillaged and taken to Paris. After the war in 1815, the French government agreed to return them but only the Codex Atlanticus found its way back to Milan; the rest remained in Paris. The appendix to one notebook, dealing with the flight of birds, was later regarded as of sufficient importance to stand on its own. Four small collections reached Britain at various times during the seventeenth and eighteenth centuries; of these, the volume in the Royal Collection at Windsor Castle is notable for its magnificent series of anatomical drawings. Other collections include the Codex Leicester and Codex Arundel in the British Museum in London, and the Madrid Codices in Spain.Towards the end of the nineteenth century, Leonardo's true stature as scientist, engineer and inventor began to emerge, particularly with the publication of transcriptions and translations of his notebooks. The volumes in Paris appeared in 1881–97 and the Codex Atlanticus was published in Milan between 1894 and 1904.[br]Principal Honours and Distinctions"Premier peintre, architecte et mécanicien du Roi" to King François I of France, 1516.Further ReadingE.MacCurdy, 1939, The Notebooks of Leonardo da Vinci, 2 vols, London; 2nd edn, 1956, London (the most extensive selection of the notes, with an English translation).G.Vasari (trans.

22 Paxton, Sir Joseph
[br]b. 3 August 1801 Milton Bryant, Bedfordshire, Englandd. 8 June 1865 Sydenham, London, England[br]English designer of the Crystal Palace, the first large-scale prefabricated ferrovitreous structure.[br]The son of a farmer, he had worked in gardens since boyhood and at the age of 21 was employed as Undergardener at the Horticultural Society Gardens in Chiswick, from where he went on to become Head Gardener for the Duke of Devonshire at Chatsworth. It was there that he developed his methods of glasshouse construction, culminating in the Great Conservatory of 1836–40, an immense structure some 277 ft (84.4 m) long, 123 ft (37.5 m) wide and 67 ft (20.4 m) high. Its framework was of iron and its roof of glass, with wood to contain the glass panels; it is now demolished. Paxton went on to landscape garden design, fountain and waterway engineering, the laying out of the model village of Edensor, and to play a part in railway and country house projects.The structure that made Paxton a household name was erected in Hyde Park, London, to house the Great Exhibition of 1851 and was aptly dubbed, by Punch, the Crystal Palace. The idea of holding an international exhibition for industry had been mooted in 1849 and was backed by Prince Albert and Henry Cole. The money for this was to be raised by public subscription and 245 designs were entered into a competition held in 1850; however, most of the concepts, received from many notable architects and engineers, were very costly and unsuitable, and none were accepted. That same year, Paxton published his scheme in the Illustrated London News and it was approved after it received over-whelming public support.Paxton's Crystal Palace, designed and erected in association with the engineers Fox and Henderson, was a prefabricated glasshouse of vast dimensions: it was 1,848 ft (563.3 m) long, 408 ft (124.4 m) wide and over 100 ft (30.5 m) high. It contained 3,300 iron columns, 2,150 girders. 24 miles (39 km) of guttering, 600,000 ft3 (17,000 m3) of timber and 900,000 ft2 (84,000 m) of sheet glass made by Chance Bros, of Birmingham. One of the chief reasons why it was accepted by the Royal Commission Committee was that it fulfilled the competition proviso that it should be capable of being erected quickly and subsequently dismantled and re-erected elsewhere. The Crystal Palace was to be erected at a cost of £79,800, much less than the other designs. Building began on 30 July 1850, with a labour force of some 2,000, and was completed on 31 March 1851. It was a landmark in construction at the time, for its size, speed of construction and its non-eclectic design, and, most of all, as the first great prefabricated building: parts were standardized and made in quantity, and were assembled on site. The exhibition was opened by Queen Victoria on 1 May 1851 and had received six million visitors when it closed on 11 October. The building was dismantled in 1852 and reassembled, with variations in design, at Sydenham in south London, where it remained until its spectacular conflagration in 1936.[br]Principal Honours and DistinctionsKnighted 1851.

23 Stephenson, George
[br]b. 9 June 1781 Wylam, Northumberland, Englandd. 12 August 1848 Tapton House, Chesterfield, England[br]English engineer, "the father of railways".[br]George Stephenson was the son of the fireman of the pumping engine at Wylam colliery, and horses drew wagons of coal along the wooden rails of the Wylam wagonway past the house in which he was born and spent his earliest childhood. While still a child he worked as a cowherd, but soon moved to working at coal pits. At 17 years of age he showed sufficient mechanical talent to be placed in charge of a new pumping engine, and had already achieved a job more responsible than that of his father. Despite his position he was still illiterate, although he subsequently learned to read and write. He was largely self-educated.In 1801 he was appointed Brakesman of the winding engine at Black Callerton pit, with responsibility for lowering the miners safely to their work. Then, about two years later, he became Brakesman of a new winding engine erected by Robert Hawthorn at Willington Quay on the Tyne. Returning collier brigs discharged ballast into wagons and the engine drew the wagons up an inclined plane to the top of "Ballast Hill" for their contents to be tipped; this was one of the earliest applications of steam power to transport, other than experimentally.In 1804 Stephenson moved to West Moor pit, Killingworth, again as Brakesman. In 1811 he demonstrated his mechanical skill by successfully modifying a new and unsatisfactory atmospheric engine, a task that had defeated the efforts of others, to enable it to pump a drowned pit clear of water. The following year he was appointed Enginewright at Killingworth, in charge of the machinery in all the collieries of the "Grand Allies", the prominent coal-owning families of Wortley, Liddell and Bowes, with authorization also to work for others. He built many stationary engines and he closely examined locomotives of John Blenkinsop's type on the Kenton \& Coxlodge wagonway, as well as those of William Hedley at Wylam.It was in 1813 that Sir Thomas Liddell requested George Stephenson to build a steam locomotive for the Killingworth wagonway: Blucher made its first trial run on 25 July 1814 and was based on Blenkinsop's locomotives, although it lacked their rack-and-pinion drive. George Stephenson is credited with building the first locomotive both to run on edge rails and be driven by adhesion, an arrangement that has been the conventional one ever since. Yet Blucher was far from perfect and over the next few years, while other engineers ignored the steam locomotive, Stephenson built a succession of them, each an improvement on the last.During this period many lives were lost in coalmines from explosions of gas ignited by miners' lamps. By observation and experiment (sometimes at great personal risk) Stephenson invented a satisfactory safety lamp, working independently of the noted scientist Sir Humphry Davy who also invented such a lamp around the same time.In 1817 George Stephenson designed his first locomotive for an outside customer, the Kilmarnock \& Troon Railway, and in 1819 he laid out the Hetton Colliery Railway in County Durham, for which his brother Robert was Resident Engineer. This was the first railway to be worked entirely without animal traction: it used inclined planes with stationary engines, self-acting inclined planes powered by gravity, and locomotives.On 19 April 1821 Stephenson was introduced to Edward Pease, one of the main promoters of the Stockton \& Darlington Railway (S \& DR), which by coincidence received its Act of Parliament the same day. George Stephenson carried out a further survey, to improve the proposed line, and in this he was assisted by his 18-year-old son, Robert Stephenson, whom he had ensured received the theoretical education which he himself lacked. It is doubtful whether either could have succeeded without the other; together they were to make the steam railway practicable.At George Stephenson's instance, much of the S \& DR was laid with wrought-iron rails recently developed by John Birkinshaw at Bedlington Ironworks, Morpeth. These were longer than cast-iron rails and were not brittle: they made a track well suited for locomotives. In June 1823 George and Robert Stephenson, with other partners, founded a firm in Newcastle upon Tyne to build locomotives and rolling stock and to do general engineering work: after its Managing Partner, the firm was called Robert Stephenson \& Co.In 1824 the promoters of the Liverpool \& Manchester Railway (L \& MR) invited George Stephenson to resurvey their proposed line in order to reduce opposition to it. William James, a wealthy land agent who had become a visionary protagonist of a national railway network and had seen Stephenson's locomotives at Killingworth, had promoted the L \& MR with some merchants of Liverpool and had carried out the first survey; however, he overreached himself in business and, shortly after the invitation to Stephenson, became bankrupt. In his own survey, however, George Stephenson lacked the assistance of his son Robert, who had left for South America, and he delegated much of the detailed work to incompetent assistants. During a devastating Parliamentary examination in the spring of 1825, much of his survey was shown to be seriously inaccurate and the L \& MR's application for an Act of Parliament was refused. The railway's promoters discharged Stephenson and had their line surveyed yet again, by C.B. Vignoles.The Stockton \& Darlington Railway was, however, triumphantly opened in the presence of vast crowds in September 1825, with Stephenson himself driving the locomotive Locomotion, which had been built at Robert Stephenson \& Co.'s Newcastle works. Once the railway was at work, horse-drawn and gravity-powered traffic shared the line with locomotives: in 1828 Stephenson invented the horse dandy, a wagon at the back of a train in which a horse could travel over the gravity-operated stretches, instead of trotting behind.Meanwhile, in May 1826, the Liverpool \& Manchester Railway had successfully obtained its Act of Parliament. Stephenson was appointed Engineer in June, and since he and Vignoles proved incompatible the latter left early in 1827. The railway was built by Stephenson and his staff, using direct labour. A considerable controversy arose c. 1828 over the motive power to be used: the traffic anticipated was too great for horses, but the performance of the reciprocal system of cable haulage developed by Benjamin Thompson appeared in many respects superior to that of contemporary locomotives. The company instituted a prize competition for a better locomotive and the Rainhill Trials were held in October 1829.Robert Stephenson had been working on improved locomotive designs since his return from America in 1827, but it was the L \& MR's Treasurer, Henry Booth, who suggested the multi-tubular boiler to George Stephenson. This was incorporated into a locomotive built by Robert Stephenson for the trials: Rocket was entered by the three men in partnership. The other principal entrants were Novelty, entered by John Braithwaite and John Ericsson, and Sans Pareil, entered by Timothy Hackworth, but only Rocket, driven by George Stephenson, met all the organizers' demands; indeed, it far surpassed them and demonstrated the practicability of the long-distance steam railway. With the opening of the Liverpool \& Manchester Railway in 1830, the age of railways began.Stephenson was active in many aspects. He advised on the construction of the Belgian State Railway, of which the Brussels-Malines section, opened in 1835, was the first all-steam railway on the European continent. In England, proposals to link the L \& MR with the Midlands had culminated in an Act of Parliament for the Grand Junction Railway in 1833: this was to run from Warrington, which was already linked to the L \& MR, to Birmingham. George Stephenson had been in charge of the surveys, and for the railway's construction he and J.U. Rastrick were initially Principal Engineers, with Stephenson's former pupil Joseph Locke under them; by 1835 both Stephenson and Rastrick had withdrawn and Locke was Engineer-in-Chief. Stephenson remained much in demand elsewhere: he was particularly associated with the construction of the North Midland Railway (Derby to Leeds) and related lines. He was active in many other places and carried out, for instance, preliminary surveys for the Chester \& Holyhead and Newcastle \& Berwick Railways, which were important links in the lines of communication between London and, respectively, Dublin and Edinburgh.He eventually retired to Tapton House, Chesterfield, overlooking the North Midland. A man who was self-made (with great success) against colossal odds, he was ever reluctant, regrettably, to give others their due credit, although in retirement, immensely wealthy and full of honour, he was still able to mingle with people of all ranks.[br]Principal Honours and DistinctionsPresident, Institution of Mechanical Engineers, on its formation in 1847.

28 Arnold, Aza
SUBJECT AREA: Textiles[br]b. 4 October 1788 Smithfield, Pawtucket, Rhode Island, USAd. 1865 Washington, DC, USA[br]American textile machinist who applied the differential motion to roving frames, solving the problem of winding on the delicate cotton rovings.[br]He was the son of Benjamin and Isabel Arnold, but his mother died when he was 2 years old and after his father's second marriage he was largely left to look after himself. After attending the village school he learnt the trade of a carpenter, and following this he became a machinist. He entered the employment of Samuel Slater, but left after a few years to engage in the unsuccessful manufacture of woollen blankets. He became involved in an engineering shop, where he devised a machine for taking wool off a carding machine and making it into endless slivers or rovings for spinning. He then became associated with a cotton-spinning mill, which led to his most important invention. The carded cotton sliver had to be reduced in thickness before it could be spun on the final machines such as the mule or the waterframe. The roving, as the mass of cotton fibres was called at this stage, was thin and very delicate because it could not be twisted to give strength, as this would not allow it to be drawn out again during the next stage. In order to wind the roving on to bobbins, the speed of the bobbin had to be just right but the diameter of the bobbin increased as it was filled. Obtaining the correct reduction in speed as the circumference increased was partially solved by the use of double-coned pulleys, but the driving belt was liable to slip owing to the power that had to be transmitted.The final solution to the problem came with the introduction of the differential drive with bevel gears or a sun-and-planet motion. Arnold had invented this compound motion in 1818 but did not think of applying it to the roving frame until 1820. It combined the direct-gearing drive from the main shaft of the machine with that from the cone-drum drive so that the latter only provided the difference between flyer and bobbin speeds, which meant that most of the transmission power was taken away from the belt. The patent for this invention was issued to Arnold on 23 January 1823 and was soon copied in Britain by Henry Houldsworth, although J.Green of Mansfield may have originated it independendy in the same year. Arnold's patent was widely infringed in America and he sued the Proprietors of the Locks and Canals, machine makers for the Lowell manufacturers, for $30,000, eventually receiving $3,500 compensation. Arnold had his own machine shop but he gave it up in 1838 and moved the Philadelphia, where he operated the Mulhausen Print Works. Around 1850 he went to Washington, DC, and became a patent attorney, remaining as such until his death. On 24 June 1856 he was granted patent for a self-setting and self-raking saw for sawing machines.[br]Bibliography28 June 1856, US patent no. 15,163 (self-setting and self-raking saw for sawing machines).Further ReadingDictionary of American Biography, Vol. 1.W.English, 1969, The Textile Industry, London (a description of the principles of the differential gear applied to the roving frame).D.J.Jeremy, 1981, Transatlantic Industrial Revolution.

29 Donkin, Bryan II
[br]b. 29 April 1809 London, Englandd. 4 December 1893 Blackheath, Kent, England[br]English mechanical engineer.[br]Bryan Donkin was the fifth son of Bryan Donkin I (1768–1855) and was educated at schools in Bromley (Kent), London, Paris and Nantes. He was an apprentice in his father's Bermondsey works and soon became an active and valuable assistant in the design and construction of papermaking, printing, pumping and other machinery. In 1829 he was sent to France to superintend the construction of paper mills and other machinery at Nantes. He later became a partner in the firm which in 1858 received an order to construct and set up a large paper mill at St Petersburg. This work took him to Russia several times before its completion in 1862. He obtained several patents relating to paper-making and steam engines. He was elected an associate of the Institution of Civil Engineers in 1835 and a member in 1840.[br]Principal Honours and DistinctionsMember, Smeatonian Society of Civil Engineers 1859; President 1872.RTS -
30 Poniatoff, Alexander Mathew
[br]b. 25 March 1892 Kazan District, Russiad. 24 October 1980[br]Russian (naturalized American in 1932) electrical engineer responsible for the development of the professional tape recorder and the first commercially-successful video tape recorder (VTR).[br]Poniatoff was educated at the University of Kazan, the Imperial College in Moscow, and the Technische Hochschule in Karlsruhe, gaining degrees in mechanical and electrical engineering. He was in Germany when the First World War broke out, but he managed to escape back to Russia, where he served as an Air Force pilot with the Imperial Russian Navy. During the Russian Revolution he was a pilot with the White Russian Forces, and escaped into China in 1920; there he found work as an assistant engineer in the Shanghai Power Company. In 1927 he immigrated to the USA, becoming a US citizen in 1932. He obtained a post in the research and development department of the General Electric Company in Schenectady, New York, and later at Dalmo Victor, San Carlos, California. During the Second World War he was involved in the development of airborne radar for the US Navy.In 1944, taking his initials to form the title, Poniatoff founded the AMPEX Corporation to manufacture components for the airborne radar developed at General Electric, but in 1946 he turned to the production of audio tape recorders developed from the German wartime Telefunken Magnetophon machine (the first tape recorder in the truest sense). In this he was supported by the entertainer Bing Crosby, who needed high-quality replay facilities for broadcasting purposes, and in 1947 he was able to offer a professional-quality product and the business prospered.With the rapid post-war boom in television broadcasting in the USA, a need soon arose for a video recorder to provide "time-shifting" of live TV programmes between the different US time zones. Many companies therefore endeavoured to produce a video tape recorder (VTR) using the same single-track, fixed-head, longitudinal-scan system used for audio, but the very much higher bandwidth required involved an unacceptably high tape-speed. AMPEX attempted to solve the problem by using twelve parallel tracks and a machine was demonstrated in 1952, but it proved unsatisfactory.The development team, which included Charles Ginsburg and Ray Dolby, then devised a four-head transverse-scan system in which a quadruplex head rotating at 14,400 rpm was made to scan across the width of a 2 in. (5 cm) tape with a tape-to-head speed of the order of 160 ft/sec (about 110 mph; 49 m/sec or 176 km/h) but with a longitudinal tape speed of only 15 in./sec (0.38 m/sec). In this way, acceptable picture quality was obtained with an acceptable tape consumption. Following a public demonstration on 14 April 1956, commercial produc-tion of studio-quality machines began to revolutionize the production and distribution of TV programmes, and the perfecting of time-base correctors which could stabilize the signal timing to a few nanoseconds made colour VTRs a practical proposition. However, AMPEX did not rest on its laurels and in the face of emerging competition from helical scan machines, where the tracks are laid diagonally on the tape, the company was able to demonstrate its own helical machine in 1957. Another development was the Videofile system, in which 250,000 pages of facsimile could be recorded on a single tape, offering a new means of archiving information. By 1986, quadruplex VTRs were obsolete, but Poniatoff's role in making television recording possible deserves a place in history.Poniatoff was President of AMPEX Corporation until 1955 and then became Chairman of the Board, a position he held until 1970.[br]Further ReadingA.Abrahamson, 1953, "A short history of television recording", Part I, JSMPTE 64:73; 1973, Part II, Journal of the Society of Motion Picture and Television Engineers, 82:188 (provides a fuller background).Audio Biographies, 1961, ed.

31 Wasborough, Matthew
SUBJECT AREA: Steam and internal combustion engines[br]b. 1753 Bristol, Englandd. 21 October 1781 Bristol, England[br]English patentee of an application of the flywheel to create a rotative steam engine.[br]A single-cylinder atmospheric steam engine had a power stroke only when the piston descended the cylinder: a means had to be found of returning the piston to its starting position. For rotative engines, this was partially solved by the patent of Matthew Wasborough in 1779. His father was a partner in a Bristol brass-founding and clockmaking business in Narrow Wine Street where he was joined by his son. Wasborough proposed to use some form of ratchet gear to effect the rotary motion and added a flywheel, the first time one was used in a steam engine, "in order to render the motion more regular and uniform". He installed one engine to drive the lathes in the Bristol works and another at James Pickard's flour mill at Snow Hill, Birmingham, where Pickard applied his recently patented crank to it. It was this Wasborough-Pickard engine which posed a threat to Boulton \& Watt trying to develop a rotative engine, for Wasborough built several engines for cornmills in Bristol, woollen mills in Gloucestershire and a block factory at Southampton before his early death. Matthew Boulton was told that Wasborough was "so intent upon the study of engines as to bring a fever on his brain and he dyed in consequence thereof…. How dangerous it is for a man to wade out of his depth" (Jenkins 1936:106).[br]Bibliography1779, British patent no. 1,213 (rotative engine with flywheel).Further ReadingJ.Tann, 1978–9, "Makers of improved Newcomen engines in the late 18th century, and R.A.Buchanan", 1978–9, "Steam and the engineering community in the eighteenth century", Transactions of the Newcomen Society 50 ("Thomas Newcomen.
