  • 41 Reason, Richard Edmund

    [br]
    b. 21 December 1903 Exeter, Devon, England
    d. 20 March 1987 Great Bowden, Leicestershire, England
    [br]
    English metrologist who developed instruments for measuring machined-surface roughness.
    [br]
    Richard Edmund Reason was educated at Tonbridge School and the Royal College of Science (Imperial College), where he studied under Professor A.F.C.Pollard, Professor of Technical Optics. After graduating in 1925 he joined Taylor, Taylor and Hobson Ltd, Leicester, manufacturers of optical, electrical and scientific instruments, and remained with that firm throughout his career. One of his first contributions was in the development, with E.F.Fincham, of the Fincham Coincidence Optometer. At this time the firm, under William Taylor, was mainly concerned with optical instruments and lens manufacture, but in the 1930s Reason was also engaged in developing means for measuring the roughness of machined surfaces. The need for establishing standards and methods of measurement of surface finish was called for when the subcontracting of aero-engine components became necessary during the Second World War. This led to the development by Reason of an instrument in which a stylus was moved across the surface and the profile recorded electronically. This was called the Talysurf and was first produced in 1941. Further development followed, and from 1947 Reason tackled the problem of measuring roundness, producing the first Talyrond machine in 1949. The technology developed for these instruments was used in the production of others such as the Talymin Comparator and the Talyvel electronic level. Reason was also associated with the development of optical projection systems to measure the profile of parts such as gear teeth, screw threads and turbine blades. He retired in 1968 but continued as a consultant to the company. He served for many years on committees of the British Standards Institution on surface metrology and was a representative of Britain at the International Standards Organization.

  • 42 Roberts, Richard

    [br]
    b. 22 April 1789 Carreghova, Llanymynech, Montgomeryshire, Wales
    d. 11 March 1864 London, England
    [br]
    Welsh mechanical engineer and inventor.
    [br]
    Richard Roberts was the son of a shoemaker and tollkeeper and received only an elementary education at the village school. At the age of 10 his interest in mechanics was stimulated when he was allowed by the Curate, the Revd Griffith Howell, to use his lathe and other tools. As a young man Roberts acquired a considerable local reputation for his mechanical skills, but these were exercised only in his spare time. For many years he worked in the local limestone quarries, until at the age of 20 he obtained employment as a pattern-maker in Staffordshire. In the next few years he worked as a mechanic in Liverpool, Manchester and Salford before moving in 1814 to London, where he obtained employment with Henry Maudslay. In 1816 he set up on his own account in Manchester. He soon established a reputation there for gear-cutting and other general engineering work, especially for the textile industry, and by 1821 he was employing about twelve men. He built machine tools mainly for his own use, including, in 1817, one of the first planing machines.
    One of his first inventions was a gas meter, but his first patent was obtained in 1822 for improvements in looms. His most important contribution to textile technology was his invention of the self-acting spinning mule, patented in 1825. The normal fourteen-year term of this patent was extended in 1839 by a further seven years. Between 1826 and 1828 Roberts paid several visits to Alsace, France, arranging cottonspinning machinery for a new factory at Mulhouse. By 1826 he had become a partner in the firm of Sharp Brothers, the company then becoming Sharp, Roberts \& Co. The firm continued to build textile machinery, and in the 1830s it built locomotive engines for the newly created railways and made one experimental steam-carriage for use on roads. The partnership was dissolved in 1843, the Sharps establishing a new works to continue locomotive building while Roberts retained the existing factory, known as the Globe Works, where he soon after took as partners R.G.Dobinson and Benjamin Fothergill (1802–79). This partnership was dissolved c. 1851, and Roberts continued in business on his own for a few years before moving to London as a consulting engineer.
    During the 1840s and 1850s Roberts produced many new inventions in a variety of fields, including machine tools, clocks and watches, textile machinery, pumps and ships. One of these was a machine controlled by a punched-card system similar to the Jacquard loom for punching rivet holes in plates. This was used in the construction of the Conway and Menai Straits tubular bridges. Roberts was granted twenty-six patents, many of which, before the Patent Law Amendment Act of 1852, covered more than one invention; there were still other inventions he did not patent. He made his contribution to the discussion which led up to the 1852 Act by publishing, in 1830 and 1833, pamphlets suggesting reform of the Patent Law.
    In the early 1820s Roberts helped to establish the Manchester Mechanics' Institute, and in 1823 he was elected a member of the Literary and Philosophical Society of Manchester. He frequently contributed to their proceedings and in 1861 he was made an Honorary Member. He was elected a Member of the Institution of Civil Engineers in 1838. From 1838 to 1843 he served as a councillor of the then-new Municipal Borough of Manchester. In his final years, without the assistance of business partners, Roberts suffered financial difficulties, and at the time of his death a fund for his aid was being raised.

  • 43 Root, Elisha King

    [br]
    b. 10 May 1808 Ludlow, Massachusetts, USA
    d. 31 August 1865 Hartford, Connecticut, USA
    [br]
    American mechanical engineer and inventor.
    [br]
    After an elementary education, Elisha K.Root was apprenticed as a machinist and worked in that occupation at Ware and Chicopee Falls, Massachusetts. In 1832 he went to Collinsville, Connecticut, to join the Collins Company, manufacturers of axes. He started as a lathe hand but soon became Foreman and, in 1845, Superintendent. While with the company, he devised and patented special-purpose machinery for forming axes which transformed the establishment from a primitive workshop to a modern factory.
    In 1849 Root was offered positions by four different manufacturers and accepted the post of Superintendent of the armoury then being planned at Hartford, Connecticut, by Samuel Colt for the manufacture of his revolver pistol, which he had invented in 1835. Initial acceptance of the revolver was slow, but by the mid1840s Colt had received sufficient orders to justify the establishment of a new factory and Root was engaged to design and install the machinery. The principle of interchangeable manufacture was adopted, and Root devised special machines for boring, rifling, making cartridges, etc., and a system of jigs, fixtures, tools and gauges. One of these special machines was a drop hammer that he invented and patented in 1853 and which established the art of die-forging on a modern basis. He was also associated with F.A. Pratt in the design of the "Lincoln" milling machine in 1855.
    When Colt died in 1862, Root became President of the company and continued in that capacity until his own death. It was said that he was one of the ablest and most highly paid mechanics from New England and that he was largely responsible for the success of both the Collins and the Colt companies.

  • 44 Taylor, Frederick Winslow

    [br]
    b. 20 March 1856 Germantown, Pennsylvania, USA
    d. 21 March 1915 Philadelphia, Pennsylvania, USA
    [br]
    American mechanical engineer and pioneer of scientific management.
    [br]
    Frederick W.Taylor received his early education from his mother, followed by some years of schooling in France and Germany. Then in 1872 he entered Phillips Exeter Academy, New Hampshire, to prepare for Harvard Law School, as it was intended that he should follow his father's profession. However, in 1874 he had to abandon his studies because of poor eyesight, and he began an apprenticeship at a pump-manufacturing works in Philadelphia learning the trades of pattern-maker and machinist. On its completion in 1878 he joined the Midvale Steel Company, at first as a labourer but then as Shop Clerk and Foreman, finally becoming Chief Engineer in 1884. At the same time he was able to resume study in the evenings at the Stevens Institute of Technology, and in 1883 he obtained the degree of Mechanical Engineer (ME). He also found time to take part in amateur sport and in 1881 he won the tennis doubles championship of the United States.
    It was while with the Midvale Steel Company that Taylor began the systematic study of workshop management, and the application of his techniques produced significant increases in the company's output and productivity. In 1890 he became Manager of a company operating large paper mills in Maine and Wisconsin, until 1893 when he set up on his own account as a consulting engineer specializing in management organization. In 1898 he was retained exclusively by the Bethlehem Steel Company, and there continued his work on the metal-cutting process that he had started at Midvale. In collaboration with J.Maunsel White (1856–1912) he developed high-speed tool steels and their heat treatment which increased cutting capacity by up to 300 per cent. He resigned from the Bethlehem Steel Company in 1901 and devoted the remainder of his life to expounding the principles of scientific management which became known as "Taylorism". The Society to Promote the Science of Management was established in 1911, renamed the Taylor Society after his death. He was an active member of the American Society of Mechanical Engineers and was its President in 1906; his presidential address "On the Art of Cutting Metals" was reprinted in book form.

  • 45 Wilkinson, David

    [br]
    b. 5 January 1771 Smithfield (now Slatersville), Rhode Island, USA
    d. 3 February 1852 Caledonia Springs, Ontario, Canada
    [br]
    American mechanical engineer and inventor of a screw-cutting lathe.
    [br]
    David Wilkinson was the third son of Oziel Wilkinson (1744–1815), a blacksmith who c.1783 established at Pawtucket, Rhode Island, a plant for making farm tools and domestic utensils. This enterprise he steadily expanded with the aid of his sons, until by 1800 it was regarded as the leading iron and machinery manufacturing business in New England. At the age of 13, David Wilkinson entered his father's workshops. Their products included iron screws, and the problem of cutting the threads was one that engaged his attention. After working on it for some years he devised a screw-cutting lathe, for which he obtained a patent in 1798. In about 1800 David and his brother Daniel established their own factory at Pawtucket, known as David Wilkinson \& Co., where they specialized in the manufacture of textile machinery. Later they began to make cast cannon and installed a special boring machine for machining them. The firm prospered until 1829, when a financial crisis caused its collapse. David Wilkinson set up a new business in Cohoes, New York, but this was not a success and from 1836 he travelled around finding work chiefly in canal and bridge construction in New Jersey, Ohio and Canada. In 1848 he petitioned Congress for some reward for his invention of the screw-cutting lathe of 1798; he was awarded $10,000.

    d. 22 December 1906 Bridgeport, Connecticut, USA
    [br]
    American mechanical engineer and machine-tool manufacturer who designed machines for boring.
    [br]
    Edward Payson Bullard served his apprenticeship at the Whitin Machine Works, Whitinsville, Massachusetts, and worked at the Colt Armory in Hartford, Connecticut, until 1863; he then entered the employ of Pratt \& Whitney, also in Hartford. He later formed a partnership with J.H.Prest and William Parsons manufacturing millwork and tools, the firm being known as Bullard \& Prest. In 1866 Bullard organized the Norwalk Iron Works Company of Norwalk, Connecticut, but afterwards withdrew and continued the business in Hartford. In 1868 the firm of Bullard \& Prest was dissolved and Bullard became Superintendent of a large machine shop in Athens, Georgia. He later organized the machine tool department of Post \& Co. at Cincinnati, and in 1872 he was made General Superintendent of the Gill Car Works at Columbus, Ohio. In 1875 he established a machinery business in Beekman Street, New York, under the name of Allis, Bullard \& Co. Mr Allis withdrew in 1877, and the Bullard Machine Company was organized.
    In 1880 Bullard secured entire control of the business and also became owner of the Bridgeport Machine Tool Works, Bridgeport, Connecticut. In 1883 he designed his first vertical boring and turning mill with a single head and belt feed and a 37 in. (94 cm) capacity; this was the first small boring machine designed to do the accurate work previously done on the face plate of a lathe. In 1889 Bullard gave up his New York interests and concentrated his entire attention on manufacturing at Bridgeport, the business being incorporated in 1894 as the Bullard Machine Tool Company. The company specialized in the construction of boring machines, the design being developed so that it became essentially a vertical turret lathe. After Bullard's death, his son Edward Payson Bullard II (b. 10 July 1872 Columbus, Ohio, USA; d. 26 June 1953 Fairfield, Connecticut, USA) continued as head of the company and further developed the boring machine into a vertical multi-spindle automatic lathe which he called the "Mult-au-matic" lathe. Both father and son were members of the American Society of Mechanical Engineers.

    d. 28 February 1844 London, England
    [br]
    English machine tool builder and inventor.
    [br]
    Although known as Clement in his professional life, his baptism at Asby and his death were registered under the name of Joseph Clemmet. He worked as a slater until the age of 23, but his interest in mechanics led him to spend much of his spare time in the local blacksmith's shop. By studying books on mechanics borrowed from his cousin, a watchmaker, he taught himself and with the aid of the village blacksmith made his own lathe. By 1805 he was able to give up the slating trade and find employment as a mechanic in a small factory at Kirkby Stephen. From there he moved to Carlisle for two years, and then to Glasgow where, while working as a turner, he took lessons in drawing; he had a natural talent and soon became an expert draughtsman. From about 1809 he was employed by Leys, Mason \& Co. of Aberdeen designing and making power looms. For this work he built a screw-cutting lathe and continued his self-education. At the end of 1813, having saved about £100, he made his way to London, where he soon found employment as a mechanic and draughtsman. Within a few months he was engaged by Joseph Bramah, and after a trial period a formal agreement dated 1 April 1814 was made by which Clement was to be Chief Draughtsman and Superintendent of Bramah's Pimlico works for five years. However, Bramah died in December 1814 and after his sons took over the business it was agreed that Clement should leave before the expiry of the five-year period. He soon found employment as Chief Draughtsman with Henry Maudslay \& Co. By 1817 Clement had saved about £500, which enabled him to establish his own business at Prospect Place, Newington Butts, as a mechanical draughtsman and manufacturer of high-class machinery. For this purpose he built lathes for his own use and invented various improvements in their detailed design. In 1827 he designed and built a facing lathe which incorporated an ingenious system of infinitely variable belt gearing. He had also built his own planing machine by 1820 and another, much larger one in 1825. In 1828 Clement began making fluted taps and dies and standardized the screw threads, thus anticipating on a small scale the national standards later established by Sir Joseph Whitworth. Because of his reputation for first-class workmanship, Clement was in the 1820s engaged by Charles Babbage to carry out the construction of his first Difference Engine.

    [br]
    b. 27 November 1876 Mutz, Austria
    d. 23 August 1834 Unterach, Austria
    [br]
    Austrian engineer, inventor of the Kaplan turbine.
    [br]
    Kaplan was educated at the Realschule in Vienna and went on to the Technische Hochschule to study machine construction, gaining his engineer's diploma in 1900. He spent a year in voluntary service in the Navy before entering Ganz \& Co. at Lebersdorf, where he was engaged in the manufacture of diesel engines. In 1903 he turned to an academic career, first with a professorship in kinematics, theoretical machine studies and machine construction at the Technische Hochschule in Brunn (now Brno). In 1918 he became Professor of Water Turbine Construction, remaining as such until his early retirement for health reasons in 1931.
    Kaplan's first publication on turbines, in 1908, was an extension of work carried out for his doctorate at the Technische Hochschule in Vienna and concerned the Francis-type turbine. Kaplan went on to develop and patent the form of water turbine that came to bear his name. It is a reaction turbine which uses a large flow on a low head and which is made like a ship's propeller with variable-pitch vanes running in a close-fitting casing. Its application was neglected at first, but since the 1920s it has become the basic turbine for most high-powered hydroelectric plant: the turbines have been capable of around 85 per cent efficiency and modern developments have raised this figure still further. Perhaps the most impressive application of the Kaplan turbine and its derivatives is the great tidal-power scheme in the estuary of the Rance by St-Malo in France, completed in 1966. The turbines probably have to meet a greater demand for flexibility than any others, for they must operate at constant speed with variable head, as the tide ebbs and flows.

    d. 27 October 1942 Plainville, Connecticut, USA
    [br]
    American mechanical engineer and machine-tool designer.
    [br]
    After an elementary education at the public schools of Plainville and Thomaston, Connecticut, Charles H.Norton started work in 1866 at the Seth Thomas Clock Company in Thomaston. He was soon promoted to machinist, and further progress led to his successive appointments as Foreman, Superintendent of Machinery and Manager of the department making tower clocks. He designed many public clocks.
    In 1886 he obtained a position as Assistant Engineer with the Brown \& Sharpe Manufacturing Company at Providence, Rhode Island, and was engaged in redesigning their universal grinding machine to give it more rigidity and make it more suitable for use as a production machine. In 1890 he left to become a partner in a newly established firm, Leland, Faulconer \& Norton Company at Detroit, Michigan, designing and building machine tools. He withdrew from this firm in 1895 and practised as a consulting mechanical engineer for a short time before returning to Brown \& Sharpe in 1896. There he designed a grinding machine incorporating larger and wider grinding wheels so that heavier cuts could be made to meet the needs of the mass-production industries, especially the automobile industry. This required a heavier and more rigid machine and greater power, but these ideas were not welcomed at Brown \& Sharpe and in 1900 Norton left to found the Norton Grinding Company in Worcester, Massachusetts. Here he was able to develop heavy-production grinding machines, including special machines for grinding crank-shafts and camshafts for the automobile industry.
    In setting up the Norton Grinding Company, Charles H.Norton received financial support from members of the Norton Emery Wheel Company (also of Worcester and known after 1906 as the Norton Company), but he was not related to the founder of that company. The two firms were completely independent until 1919 when they were merged. From that time Charles H.Norton served as Chief Engineer of the machinery division of the Norton Company, until 1934 when he became their Consulting Engineer.

    [br]
    American mechanical engineer and machine-tool manufacturer.
    [br]
    Francis A.Pratt served an apprenticeship as a machinist with Warren Aldrich, and on completing it in 1848 he entered the Gloucester Machine Works as a journeyman machinist. From 1852 to 1854 he worked at the Colt Armory in Hartford, Connecticut, where he met his future partner, Amos Whitney. He then became Superintendent of the Phoenix Iron Works, also at Hartford and run by George S.Lincoln \& Company. While there he designed the well-known "Lincoln" miller, which was first produced in 1855. This was a development of the milling machine built by Robbins \& Lawrence and designed by F.W. Howe, and incorporated a screw drive for the table instead of the rack and pinion used in the earlier machine.
    Whitney also moved to the Phoenix Iron Works, and in 1860 the two men started in a small way doing machine work on their own account. In 1862 they took a third partner, Monroe Stannard, and enlarged their workshop. The business continued to expand, but Pratt and Whitney remained at the Phoenix Iron Works until 1864 and in the following year they built their first new factory. The Pratt \& Whitney Company was incorporated in 1869 with a capital of $350,000, F.A.Pratt being elected President. The firm specialized in making machine tools and tools particularly for the armament industry. In the 1870s Pratt made no less than ten trips to Europe gaining orders for equipping armouries in many different countries. Pratt \& Whitney was one of the leading firms developing the system of interchangeable manufacture which led to the need to establish national standards of measurement. The Rogers-Bond Comparator, developed with the backing of Pratt \& Whitney, played an important part in the establishment of these standards, which formed the basis of the gauges of many various types made by the firm. Pratt remained President of the company until 1898, after which he served as their Consulting Engineer for a short time before retiring from professional life. He was granted a number of patents relating to machine tools. He was a founder member of the American Society of Mechanical Engineers in 1880 and was elected a vice-president in 1881. He was an alderman of the city of Hartford.

    [br]
    b. 1601
    d. 3 April 1667 Lambeth (?), London, England
    [br]
    English inventor of a steam-operated pump for raising water, described in his work A Century of…Inventions.
    [br]
    Edward Somerset became 6th Earl and 2nd Marquis of Worcester and Titular Earl of Glamorgan. He was educated privately and then abroad, visiting Germany, Italy and France. He was made Councillor of Wales in 1633 and Deputy Lord Lieutenant of Monmouthshire in 1635. On the outbreak of the Civil War, he was commissioned to levy forces against the Scots in 1640. He garrisoned Raglan Castle for the King and was employed by Charles I to bring troops in from Ireland. He was declared an enemy of the realm by Parliament and was banished, remaining in France for some years. On the Restoration, he recovered most of his estates, principally in South Wales, and was able to devote most of his time to mechanical studies and experiments.
    Soon after 1626, he had employed the services of a skilled Dutch or German mechanic, Caspar Kaltoff, to make small-scale models for display to interested people. In 1638 he showed Charles I a 14 ft (4.3m) diameter wheel carrying forty weights that was claimed to have solved the problem of perpetual motion. He wrote his Century of the Names and Scantlings of Such Inventions as at Present I Can Call to Mind to have Tried and Perfected in 1655, but it was not published until 1663: no. 68 describes "An admirable and most forcible way to drive up water by fire", which has been claimed as an early steam-engine. Before the Civil War he made experiments at Raglan Castle, and after the war he built one of his engines at Vauxhall, London, where it raised water to a height of 40 ft (12 m). An Act of Parliament enabling Worcester to receive the benefit and profits of his water-commanding engine for ninety-nine years did not restore his fortunes. Descriptions of this invention are so vague that it cannot be reconstructed.

    Christopher M.Spencer served an apprenticeship from 1847 to 1849 in the machine shop at the silk mills of Cheney Brothers in his native town and remained there for a few years as a journeyman machinist. In 1853 he went to Rochester, New York, to obtain experience with machinery other than that used in the textile industry. He then spent some years with the Colt Armory at Hartford, Connecticut, before returning to Cheney Brothers, where he obtained his first patent, which was for a silk-winding machine.
    Spencer had long been interested in firearms and in 1860 he obtained a patent for a repeating rifle. The Spencer Repeating Rifle Company was organized for its manufacture, and before the end of the American Civil War about 200,000 rifles had been produced. He patented a number of other improvements in firearms and in 1868 was associated with Charles E.Billings (1835–1920) in the Roper Arms Company, set up at Amherst, Massachusetts, to manufacture Spencer's magazine gun. This was not a success, however, and in 1869 they moved to Hartford, Connecticut, and formed the Billings \& Spencer Company. There they developed the technology of the drop hammer and Spencer continued his inventive work, which included an automatic turret lathe for producing metal screws. The patent that he obtained for this in 1873 inexplicably failed to protect the essential feature of the machine which provided the automatic action, with the result that Spencer received no patent right on the most valuable feature of the machine.
    In 1874 Spencer withdrew from active connection with Billings \& Spencer, although he remained a director, and in 1876 he formed with others the Hartford Machine Screw Company. However, he withdrew in 1882 to form the Spencer Arms Company at Windsor, Connecticut, for the manufacture of another of his inventions, a repeating shotgun. But this company failed and Spencer returned to the field of automatic lathes, and in 1893 he organized the Spencer Automatic Machine Screw Company at Windsor, where he remained until his retirement.

    [br]
    b. 8 October 1832 Biddeford, Maine, USA
    d. 5 August 1920 Poland Springs, Maine, USA
    [br]
    American mechanical engineer and machine-tool manufacturer.
    [br]
    Amos Whitney was a member of the same distinguished family as Eli Whitney. His father was a locksmith and machinist and he was apprenticed at the age of 14 to the Essex Machine Company of Lawrence, Massachusetts. In 1850 both he and his father were working at the Colt Armory in Hartford, Connecticut, where he first met his future partner, F.A. Pratt. They both subsequently moved to the Phoenix Iron Works, also at Hartford, and in 1860 they started in a small way doing machine work on their own account. In 1862 they took a third partner, Monroe Stannard, and enlarged their workshop. The business continued to expand, but Pratt and Whitney remained at the Phoenix Iron Works until 1864 and in the following year they built their first new factory. The Pratt \& Whitney Company was incorporated in 1869 with a capital of $350,000, Amos Whitney being appointed General Superintendent. The firm specialized in making machine tools and tools particularly for the armament industry. Pratt \& Whitney was one of the leading firms developing the system of interchangeable manufacture which led to the need to establish national standards of measurement. The Rogers-Bond Comparator, developed with the backing of Pratt \& Whitney, played an important part in the establishment of these standards, which formed the basis of the gauges of many various types made by the firm.
    Amos Whitney was made Vice-President of Pratt \& Whitney Company in 1893 and was President from 1898 until 1901, when the company was acquired by the Niles- Bement-Pond Company: he then remained as one of the directors. He was elected a Member of the American Society of Mechanical Engineers in 1913.

    SUBJECT AREA: Civil engineering
    [br]
    b. c. 1590 St Maartensdijk, Zeeland, the Netherlands
    d. 4 February 1656 probably London, England
    [br]
    Dutch/British civil engineer responsible for many of the drainage and flood-protection schemes in low-lying areas of England in the seventeenth century.
    [br]
    At the beginning of the seventeenth century, several wealthy men in England joined forces as "adventurers" to put their money into land ventures. One such group was responsible for the draining of the Fens. The first need was to find engineers who were versed in the processes of land drainage, particularly when that land was at, or below, sea level. It was natural, therefore, to turn to the Netherlands to find these skilled men. Joachim Liens was one of the first of the Dutch engineers to go to England, and he started work on the Great Level; however, no real progress was made until 1621, when Cornelius Vermuyden was brought to England to assist in the work.
    Vermuyden had grown up in a district where he could see for himself the techniques of embanking and reclaiming land from the sea. He acquired a reputation of expertise in this field, and by 1621 his fame had spread to England. In that year the Thames had flooded and breached its banks near Havering and Dagenham in Essex. Vermuyden was commissioned to repair the breach and drain neighbouring marshland, with what he claimed as complete success. The Commissioners of Sewers for Essex disputed this claim and whthheld his fee, but King Charles I granted him a portion of the reclaimed land as compensation.
    In 1626 Vermuyden carried out his first scheme for drainage works as a consultant. This was the drainage of Hatfield Chase in South Yorkshire. Charles I was, in fact, Vermuyden's employer in the drainage of the Chase, and the work was undertaken as a means of raising additional rents for the Royal Exchequer. Vermuyden was himself an "adventurer" in the undertaking, putting capital into the venture and receiving the title to a considerable proportion of the drained lands. One of the important elements of his drainage designs was the principal of "washes", which were flat areas between the protective dykes and the rivers to carry flood waters, to prevent them spreading on to nearby land. Vermuyden faced bitter opposition from those whose livelihoods depended on the marshlands and who resorted to sabotage of the embankments and violence against his imported Dutch workmen to defend their rights. The work could not be completed until arbiters had ruled out on the respective rights of the parties involved. Disagreements and criticism of his engineering practices continued and he gave up his interest in Hatfield Chase. The Hatfield Chase undertaking was not a great success, although the land is now rich farmland around the river Don in Doncaster. However, the involved financial and land-ownership arrangements were the key to the granting of a knighthood to Cornelius Vermuyden in January 1628, and in 1630 he purchased 4,000 acres of low-lying land on Sedgemoor in Somerset.
    In 1629 Vermuyden embarked on his most important work, that of draining the Great Level in the fenlands of East Anglia. Francis Russell, 4th Earl of Bedford, was given charge of the work, with Vermuyden as Engineer; in this venture they were speculators and partners and were recompensed by a grant of land. The area which contains the Cambridgeshire tributaries of the Great Ouse were subject to severe and usually annual flooding. The works to contain the rivers in their flood period were important. Whilst the rivers were contained with the enclosed flood plain, the land beyond became highly sought-after because of the quality of the soil. The fourteen "adventurers" who eventually came into partnership with the Earl of Bedford and Vermuyden were the financiers of the scheme and also received land in accordance with their input into the scheme. In 1637 the work was claimed to be complete, but this was disputed, with Vermuyden defending himself against criticism in a pamphlet entitled Discourse Touching the Great Fennes (1638; 1642, London). In fact, much remained to be done, and after an interruption due to the Civil War the scheme was finished in 1652. Whilst the process of the Great Level works had closely involved the King, Oliver Cromwell was equally concerned over the success of the scheme. By 1655 Cornelius Vermuyden had ceased to have anything to do with the Great Level. At that stage he was asked to account for large sums granted to him to expedite the work but was unable to do so; most of his assets were seized to cover the deficiency, and from then on he subsided into obscurity and poverty.
    While Cornelius Vermuyden, as a Dutchman, was well versed in the drainage needs of his own country, he developed his skills as a hydraulic engineer in England and drained acres of derelict flooded land.
