12 Marshall, William
SUBJECT AREA: Agricultural and food technology[br]b. baptized 28 July 1745 Yorkshire, Englandd. 1818 Pickering, Yorkshire, England[br]English commentator and writer on agriculture who established the first agricultural college in Britain.[br]Little is known for certain about William Marshall's early life, other than that he was baptized at Sinnington in the West Riding of Yorkshire. On his own account he was involved in trade in the West Indies from the age of 15 for a period of fourteen years. It is assumed that he was financially successful in this, for on his return to England in 1774 he was able to purchase Addisham Farm in Surrey. Having sacked his bailiff he determined to keep a minute book relating to all transactions on the farm, which he was now managing for himself. On these entries he made additional comments. The publication of these writings was the beginning of a substantial review of agriculture in Britain and a criticism of existing practices. From 1779 he acted as agent on a Norfolk estate, and his five years in that position resulted in The Rural Economy of Norfolk, the first of a series of county reviews that he was to write, intending the somewhat ambitious task of surveying the whole country. By 1808 Marshall had accumulated sufficient capital to be able to purchase a substantial property in the Vale of Cleveland, where he lived for the rest of his life. At the time of his death he was engaged in the erection of a building to serve as an agricultural college; the same building is now a rural-life museum.[br]BibliographyOther titles in his Rural Economy series included Yorkshire in 1788, Gloucester in 1789, The Midland Counties in 1790, The West of England in 1796, and The Southern Counties two years later. Further titles included Experiments and Observations Concerning Agriculture and the Weather in 1779, Observations on the Different Breeds of Sheep in 1792, The General View of the Agriculture of Central HighlandScotland in 1794, and Planting and Rural Ornament in 1796. He also wrote On the Enclosure of Commonable and Intermixed Lands in 1801, On the Landed Property of England, an Elementary Practical Treatise in 1804, and On the Management of Landed Estates in 1806. He was not asked to write any of the County Surveys produced by the Board of Agriculture, despite his own claims to the origin of the idea. Instead in 1817 he wrote A Review and Complete Abstract of the Reports of the Board of Agriculture as his own criticism of them.Further ReadingJoan Thirsk, 1989, The Agrarian History of England and Wales, Vol. VI (deals with the years 1750 to 1850, the period associated with Marshall).Pamela Horn, 1982, William Marshall (1745–1818) and the Georgian Countryside, Beacon (gives a more specific account).AP -
13 De Forest, Lee
SUBJECT AREA: Broadcasting, Electronics and information technology, Photography, film and optics, Recording, Telecommunications[br]b. 26 August 1873 Council Bluffs, Iowa, USAd. 30 June 1961 Hollywood, California, USA[br]American electrical engineer and inventor principally known for his invention of the Audion, or triode, vacuum tube; also a pioneer of sound in the cinema.[br]De Forest was born into the family of a Congregational minister that moved to Alabama in 1879 when the father became President of a college for African-Americans; this was a position that led to the family's social ostracism by the white community. By the time he was 13 years old, De Forest was already a keen mechanical inventor, and in 1893, rejecting his father's plan for him to become a clergyman, he entered the Sheffield Scientific School of Yale University. Following his first degree, he went on to study the propagation of electromagnetic waves, gaining a PhD in physics in 1899 for his thesis on the "Reflection of Hertzian Waves from the Ends of Parallel Wires", probably the first US thesis in the field of radio.He then joined the Western Electric Company in Chicago where he helped develop the infant technology of wireless, working his way up from a modest post in the production area to a position in the experimental laboratory. There, working alone after normal working hours, he developed a detector of electromagnetic waves based on an electrolytic device similar to that already invented by Fleming in England. Recognizing his talents, a number of financial backers enabled him to set up his own business in 1902 under the name of De Forest Wireless Telegraphy Company; he was soon demonstrating wireless telegraphy to interested parties and entering into competition with the American Marconi Company.Despite the failure of this company because of fraud by his partners, he continued his experiments; in 1907, by adding a third electrode, a wire mesh, between the anode and cathode of the thermionic diode invented by Fleming in 1904, he was able to produce the amplifying device now known as the triode valve and achieve a sensitivity of radio-signal reception much greater than possible with the passive carborundum and electrolytic detectors hitherto available. Patented under the name Audion, this new vacuum device was soon successfully used for experimental broadcasts of music and speech in New York and Paris. The invention of the Audion has been described as the beginning of the electronic era. Although much development work was required before its full potential was realized, the Audion opened the way to progress in all areas of sound transmission, recording and reproduction. The patent was challenged by Fleming and it was not until 1943 that De Forest's claim was finally recognized.Overcoming the near failure of his new company, the De Forest Radio Telephone Company, as well as unsuccessful charges of fraudulent promotion of the Audion, he continued to exploit the potential of his invention. By 1912 he had used transformer-coupling of several Audion stages to achieve high gain at radio frequencies, making long-distance communication a practical proposition, and had applied positive feedback from the Audion output anode to its input grid to realize a stable transmitter oscillator and modulator. These successes led to prolonged patent litigation with Edwin Armstrong and others, and he eventually sold the manufacturing rights, in retrospect often for a pittance.During the early 1920s De Forest began a fruitful association with T.W.Case, who for around ten years had been working to perfect a moving-picture sound system. De Forest claimed to have had an interest in sound films as early as 1900, and Case now began to supply him with photoelectric cells and primitive sound cameras. He eventually devised a variable-density sound-on-film system utilizing a glow-discharge modulator, the Photion. By 1926 De Forest's Phonofilm had been successfully demonstrated in over fifty theatres and this system became the basis of Movietone. Though his ideas were on the right lines, the technology was insufficiently developed and it was left to others to produce a system acceptable to the film industry. However, De Forest had played a key role in transforming the nature of the film industry; within a space of five years the production of silent films had all but ceased.In the following decade De Forest applied the Audion to the development of medical diathermy. Finally, after spending most of his working life as an independent inventor and entrepreneur, he worked for a time during the Second World War at the Bell Telephone Laboratories on military applications of electronics.[br]Principal Honours and DistinctionsInstitute of Electronic and Radio Engineers Medal of Honour 1922.

14 Hamilton, Harold Lee (Hal)
[br]b. 14 June 1890 Little Shasta, California, USAd. 3 May 1969 California, USA[br]American pioneer of diesel rail traction.[br]Orphaned as a child, Hamilton went to work for Southern Pacific Railroad in his teens, and then worked for several other companies. In his spare time he learned mathematics and physics from a retired professor. In 1911 he joined the White Motor Company, makers of road motor vehicles in Denver, Colorado, where he had gone to recuperate from malaria. He remained there until 1922, apart from an eighteenth-month break for war service.Upon his return from war service, Hamilton found White selling petrol-engined railbuses with mechanical transmission, based on road vehicles, to railways. He noted that they were not robust enough and that the success of petrol railcars with electric transmission, built by General Electric since 1906, was limited as they were complex to drive and maintain. In 1922 Hamilton formed, and became President of, the Electro- Motive Engineering Corporation (later Electro-Motive Corporation) to design and produce petrol-electric rail cars. Needing an engine larger than those used in road vehicles, yet lighter and faster than marine engines, he approached the Win ton Engine Company to develop a suitable engine; in addition, General Electric provided electric transmission with a simplified control system. Using these components, Hamilton arranged for his petrol-electric railcars to be built by the St Louis Car Company, with the first being completed in 1924. It was the beginning of a highly successful series. Fuel costs were lower than for steam trains and initial costs were kept down by using standardized vehicles instead of designing for individual railways. Maintenance costs were minimized because Electro-Motive kept stocks of spare parts and supplied replacement units when necessary. As more powerful, 800 hp (600 kW) railcars were produced, railways tended to use them to haul trailer vehicles, although that practice reduced the fuel saving. By the end of the decade Electro-Motive needed engines more powerful still and therefore had to use cheap fuel. Diesel engines of the period, such as those that Winton had made for some years, were too heavy in relation to their power, and too slow and sluggish for rail use. Their fuel-injection system was erratic and insufficiently robust and Hamilton concluded that a separate injector was needed for each cylinder.In 1930 Electro-Motive Corporation and Winton were acquired by General Motors in pursuance of their aim to develop a diesel engine suitable for rail traction, with the use of unit fuel injectors; Hamilton retained his position as President. At this time, industrial depression had combined with road and air competition to undermine railway-passenger business, and Ralph Budd, President of the Chicago, Burlington \& Quincy Railroad, thought that traffic could be recovered by way of high-speed, luxury motor trains; hence the Pioneer Zephyr was built for the Burlington. This comprised a 600 hp (450 kW), lightweight, two-stroke, diesel engine developed by General Motors (model 201 A), with electric transmission, that powered a streamlined train of three articulated coaches. This train demonstrated its powers on 26 May 1934 by running non-stop from Denver to Chicago, a distance of 1,015 miles (1,635 km), in 13 hours and 6 minutes, when the fastest steam schedule was 26 hours. Hamilton and Budd were among those on board the train, and it ushered in an era of high-speed diesel trains in the USA. By then Hamilton, with General Motors backing, was planning to use the lightweight engine to power diesel-electric locomotives. Their layout was derived not from steam locomotives, but from the standard American boxcar. The power plant was mounted within the body and powered the bogies, and driver's cabs were at each end. Two 900 hp (670 kW) engines were mounted in a single car to become an 1,800 hp (l,340 kW) locomotive, which could be operated in multiple by a single driver to form a 3,600 hp (2,680 kW) locomotive. To keep costs down, standard locomotives could be mass-produced rather than needing individual designs for each railway, as with steam locomotives. Two units of this type were completed in 1935 and sent on trial throughout much of the USA. They were able to match steam locomotive performance, with considerable economies: fuel costs alone were halved and there was much less wear on the track. In the same year, Electro-Motive began manufacturing diesel-electrie locomotives at La Grange, Illinois, with design modifications: the driver was placed high up above a projecting nose, which improved visibility and provided protection in the event of collision on unguarded level crossings; six-wheeled bogies were introduced, to reduce axle loading and improve stability. The first production passenger locomotives emerged from La Grange in 1937, and by early 1939 seventy units were in service. Meanwhile, improved engines had been developed and were being made at La Grange, and late in 1939 a prototype, four-unit, 5,400 hp (4,000 kW) diesel-electric locomotive for freight trains was produced and sent out on test from coast to coast; production versions appeared late in 1940. After an interval from 1941 to 1943, when Electro-Motive produced diesel engines for military and naval use, locomotive production resumed in quantity in 1944, and within a few years diesel power replaced steam on most railways in the USA.Hal Hamilton remained President of Electro-Motive Corporation until 1942, when it became a division of General Motors, of which he became Vice-President.[br]Further ReadingP.M.Reck, 1948, On Time: The History of the Electro-Motive Division of General Motors Corporation, La Grange, Ill.: General Motors (describes Hamilton's career).PJGRBiographical history of technology > Hamilton, Harold Lee (Hal)

15 Hurter, Ferdinand
SUBJECT AREA: Photography, film and optics[br]b. 15 March 1844 Schaffhausen, Switzerlandd. 5 March 1898[br]Swiss chemist who, with Vero Charles Driffield, established the basis of modern sensitometry in England.[br]Ferdinand Hurter worked for three years as a dyer's apprentice before entering the Polytechnic in Zurich; he transferred to Heidelberg, where he graduated in 1866. A year later he secured an appointment as a chemist for the British alkali manufacturing company, Gaskell, Deacon \& Co. of Widnes, Cheshire. In 1871 he was joined at the company by the young engineer Vero Charles Driffield, who was to become his co-worker. Driffield had worked for a professional photographer before beginning his engineering apprenticeship and it was in 1876, when Hurter sought to draw on this experience, that the partnership began. At this time the speed of the new gelatine halide dry plates was expressed in terms of the speed of a wet-collodion plate, an almost worthless concept as the speed of a collodion plate was itself variable. Hurter and Driffield sought to place the study of photographic emulsions on a more scientific basis. They constructed an actinometer to measure the intensity of sunlight and in 1890 published the first of a series of papers on the sensitivity of photographic plates. They suggested methods of exposing a plate to lights of known intensities and measuring the densities obtained on development. They were able to plot curves based on density and exposure which became known as the H \& D curve. Hurter and Driffield's work allowed them to express the characteristics of an emulsion with a nomenclature which was soon adopted by British plate manufacturers. From the 1890s onwards most British-made plates were identified with H \& D ratings. Hurter and Driffield's partnership was ended by the former's death in 1898.[br]Further ReadingW.B.Ferguson (ed.), 1920, The Photographic Researches of Ferdinand Hurter \& Vero C.

16 Miller, Patrick
SUBJECT AREA: Ports and shipping[br]b. 1731 Glasgow, Scotlandd. 9 December 1815 Dalswinton, Dumfriesshire, Scotland[br]Scottish merchant and banker, early experimenter in powered navigation and in ship form.[br]In his own words, Patrick Miller was "without a sixpence" in his early youth; this is difficult to prove one way or another as he ended his life as Director and Deputy Governor of the Bank of Scotland. One thing is clear however, that from his earliest days, in common with most of his counterparts of the late eighteenth century, he was interested in experimental and applied science. Having acquired a substantial income from other sources, Miller was able to indulge his interest in ships and engineering. His first important vessel was the trimaran Edinburgh, designed by him and launched at Leith in 1786. Propulsion was man-powered using paddle wheels positioned in the spaces between the outer and central hulls. This led to several trials of similar craft on the Forth in the 1780s, and ultimately to the celebrated Dalswinton Loch trials. In 1785 Miller had purchased the Dumfriesshire estate of Dalswinton and commenced a series of experiments on agricultural development and other matters. With the help of William Symington he built a double-hull steamship with internal paddle wheels which was tested on the Loch in 1788. The 7.6 m (25 ft) long ship travelled at 5 mph (8 km/h) on her trials, and according to unsubstantiated tradition carried a group of well-known people including the poet Robert Burns (1759–1796).Miller carried out many more important experiments and in 1796 obtained a patent for the design of shallow-drafted ships able to carry substantial cargo on flat bottoms. His main achievement may have been to stimulate William Symington, who at the beginning of the nineteenth century went on to design and build two of the world's first important steamships, each named Charlotte Dundas, for service on the Forth and Clyde Canal.[br]Further ReadingH.Philip Spratt, 1958, The Birth of the Steamboat, London: Griffiths.

17 Radcliffe, William
SUBJECT AREA: Textiles[br]b. 1761 Mellor, Cheshire, Englandd. 1842 Mellor, Cheshire, England[br]English inventor of the sizing machine.[br]Radcliffe was brought up in the textile industry and learned carding and spinning as a child. When he was old enough, he became a weaver. It was a time when there were not enough weavers to work up all the yarn being spun on the recently invented spinning machines, so some yarn was exported. Radcliffe regarded this as a sin; meetings were held to prohibit the export, and Radcliffe promised to use his best endeavours to discover means to work up the yarn in England. He owned a mill at Mellor and by 1801 was employing over 1,000 hand-loom weavers. He wanted to improve their efficiency so they could compete against power looms, which were beginning to be introduced at that time.His first step was to divide up as much as possible the different weaving processes, not unlike the plan adopted by Arkwright in spinning. In order to strengthen the warp yarns made of cotton and to reduce their tendency to fray during weaving, it was customary to apply an adhesive substance such as starch paste. This was brushed on as the warp was unwound from the back beam during weaving, so only short lengths could be treated before being dried. Instead of dressing the warp in the loom as was hitherto done, Radcliffe had it dressed in a separate machine, relieving the weaver of the trouble and saving the time wasted by the method previously used. Radcliffe employed a young man names Thomas Johnson, who proved to be a clever mechanic. Radcliffe patented his inventions in Johnson's name to avoid other people, especially foreigners, finding out his ideas. He took out his first patent, for a dressing machine, in March 1803 and a second the following year. The combined result of the two patents was the introduction of a beaming machine and a dressing machine which, in addition to applying the paste to the yarns and then drying them, wound them onto a beam ready for the loom. These machines enabled the weaver to work a loom with fewer stoppages; however, Radcliffe did not anticipate that his method of sizing would soon be applied to power looms as well and lead to the commercial success of powered weaving. Other manufacturers quickly adopted Radcliffe's system, and Radcliffe himself soon had to introduce power looms in his own business.Radcliffe improved the hand looms themselves when, with the help of Johnson, he devised a cloth taking-up motion that wound the woven cloth onto a roller automatically as the weaver operated the loom. Radcliffe and Johnson also developed the "dandy loom", which was a more compact form of hand loom and was also later adapted for weaving by power. Radcliffe was among the witnesses before the Parliamentary Committee which in 1808 awarded Edmund Cartwright a grant for his invention of the power loom. Later Radcliffe was unsuccessfully to petition Parliament for a similar reward for his contributions to the introduction of power weaving. His business affairs ultimately failed partly through his own obstinacy and his continued opposition to the export of cotton yarn. He lived to be 81 years old and was buried in Mellor churchyard.[br]Bibliography1811, Exportation of Cotton Yarn and Real Cause of the Distress that has Fallen upon the Cotton Trade for a Series of Years Past, Stockport.1828, Origin of the New System of Manufacture, Commonly Called "Power-Loom Weaving", Stockport (this should be read, even though it is mostly covers Radcliffe's political aims).Further ReadingA.Barlow, 1870, The History and Principles of Weaving by Hand and by Power, London (provides an outline of Radcliffe's life and work).W.English, 1969, The Textile Industry, London (a general background of his inventions).
