10 Senefelder, Alois
SUBJECT AREA: Paper and printing[br]b. 6 November 1771 Prague, Bohemia (now Czech Republic)d. 26 February 1834 Munich, Germany[br]German inventor of lithography.[br]Soon after his birth, Senefelder's family moved to Mannheim, where his father, an actor, had obtained a position in the state theatre. He was educated there, until he gained a scholarship to the university of Ingolstadt. The young Senefelder wanted to follow his father on to the stage, but the latter insisted that he study law. He nevertheless found time to write short pieces for the theatre. One of these, when he was 18 years old, was an encouraging success. When his father died in 1791, he gave up his studies and took to a new life as poet and actor. However, the wandering life of a repertory actor palled after two years and he settled for the more comfortable pursuit of playwriting. He had some of his work printed, which acquainted him with the art of printing, but he fell out with his bookseller. He therefore resolved to carry out his own printing, but he could not afford the equipment of a conventional letterpress printer. He began to explore other ways of printing and so set out on the path that was to lead to an entirely new method.He tried writing in reverse on a copper plate with some acid-resisting material and etching the plate, to leave a relief image that could then be inked and printed. He knew that oily substances would resist acid, but it required many experiments to arrive at a composition of wax, soap and charcoal dust dissolved in rainwater. The plates wore down with repeated polishing, so he substituted stone plates. He continued to etch them and managed to make good prints with them, but he went on to make the surprising discovery that etching was unnecessary. If the image to be printed was made with the oily composition and the stone moistened, he found that only the oily image received the ink while the moistened part rejected it. The printing surface was neither raised (as in letterpress printing) nor incised (as in intaglio printing): Senefelder had discovered the third method of printing.He arrived at a workable process over the years 1796 to 1799, and in 1800 he was granted an English patent. In the same year, lithography (or "writing on stone") was introduced into France and Senefelder himself took it to England, but it was some time before it became widespread; it was taken up by artists especially for high-quality printing of art works. Meanwhile, Senefelder improved his techniques, finding that other materials, even paper, could be used in place of stone. In fact, zinc plates were widely used from the 1820s, but the name "lithography" stuck. Although he won world renown and was honoured by most of the crowned heads of Europe, he never became rich because he dissipated his profits through restless experimenting.With the later application of the offset principle, initiated by Barclay, lithography has become the most widely used method of printing.[br]Bibliography1911, Alois Senefelder, Inventor of Lithography, trans.

11 Smith, Sir Francis Pettit
SUBJECT AREA: Ports and shipping[br]b. 9 February 1808 Copperhurst Farm, near Hythe, Kent, Englandd. 12 February 1874 South Kensington, London, England[br]English inventor of the screw propeller.[br]Smith was the only son of Charles Smith, Postmaster at Hythe, and his wife Sarah (née Pettit). After education at a private school in Ashford, Kent, he took to farming, first on Romney Marsh, then at Hendon, Middlesex. As a boy, he showed much skill in the construction of model boats, especially in devising their means of propulsion. He maintained this interest into adult life and in 1835 he made a model propelled by a screw driven by a spring. This worked so well that he became convinced that the screw propeller offered a better method of propulsion than the paddle wheels that were then in general use. This notion so fired his enthusiasm that he virtually gave up farming to devote himself to perfecting his invention. The following year he produced a better model, which he successfully demonstrated to friends on his farm at Hendon and afterwards to the public at the Adelaide Gallery in London. On 31 May 1836 Smith was granted a patent for the propulsion of vessels by means of a screw.The idea of screw propulsion was not new, however, for it had been mooted as early as the seventeenth century and since then several proposals had been advanced, but without successful practical application. Indeed, simultaneously but quite independently of Smith, the Swedish engineer John Ericsson had invented the ship's propeller and obtained a patent on 13 July 1836, just weeks after Smith. But Smith was completely unaware of this and pursued his own device in the belief that he was the sole inventor.With some financial and technical backing, Smith was able to construct a 10 ton boat driven by a screw and powered by a steam engine of about 6 hp (4.5 kW). After showing it off to the public, Smith tried it out at sea, from Ramsgate round to Dover and Hythe, returning in stormy weather. The screw performed well in both calm and rough water. The engineering world seemed opposed to the new method of propulsion, but the Admiralty gave cautious encouragement in 1839 by ordering that the 237 ton Archimedes be equipped with a screw. It showed itself superior to the Vulcan, one of the fastest paddle-driven ships in the Navy. The ship was put through its paces in several ports, including Bristol, where Isambard Kingdom Brunel was constructing his Great Britain, the first large iron ocean-going vessel. Brunel was so impressed that he adapted his ship for screw propulsion.Meanwhile, in spite of favourable reports, the Admiralty were dragging their feet and ordered further trials, fitting Smith's four-bladed propeller to the Rattler, then under construction and completed in 1844. The trials were a complete success and propelled their lordships of the Admiralty to a decision to equip twenty ships with screw propulsion, under Smith's supervision.At last the superiority of screw propulsion was generally accepted and virtually universally adopted. Yet Smith gained little financial reward for his invention and in 1850 he retired to Guernsey to resume his farming life. In 1860 financial pressures compelled him to accept the position of Curator of Patent Models at the Patent Museum in South Kensington, London, a post he held until his death. Belated recognition by the Government, then headed by Lord Palmerston, came in 1855 with the grant of an annual pension of £200. Two years later Smith received unofficial recognition when he was presented with a national testimonial, consisting of a service of plate and nearly £3,000 in cash subscribed largely by the shipbuilding and engineering community. Finally, in 1871 Smith was honoured with a knighthood.[br]Principal Honours and DistinctionsKnighted 1871.Further ReadingObituary, 1874, Illustrated London News (7 February).1856, On the Invention and Progress of the Screw Propeller, London (provides biographical details).Smith and his invention are referred to in papers in Transactions of the Newcomen Society, 14 (1934): 9; 19 (1939): 145–8, 155–7, 161–4, 237–9.LRDBiographical history of technology > Smith, Sir Francis Pettit

12 Berthollet, Claude-Louis
SUBJECT AREA: Textiles[br]b. 9 November 1748 Talloise, near Lake Annecy, Franced. 6 November 1822 Arceuil, France[br]French chemist who made important innovations in textile chemistry.[br]Berthollet qualified as a medical doctor and pursued chemical researches, notably into "muriatic acid" (chlorine), then recently discovered by Scheele. He was one of the first chemists to embrace the new system of chemistry advanced by Lavoisier. Berthollet held several official appointments, among them inspector of dye works (from 1784) and Director of the Manufacture Nationale des Gobelins. These appointments enabled him to continue his researches and embark on a series of publications on the practical applications of chlorine, prussic acid (hydrocyanic acid) and ammonia. He clearly demonstrated the benefits of the French practice of appointing scientists to the state manufactories.There were two practical results of Berthollet's studies of chlorine. First, he produced a powerful explosive by substituting potassium chlorate, formed by the action of chlorine on potash, in place of nitre (potassium nitrate) in gunpowder. Then, mainly from humanitarian motives, he followed up Scheele's observation of the bleaching properties of chlorine water, in order to release for cultivation the considerable areas of land that had hitherto been required by the old bleaching process. The chlorine method greatly speeded up bleaching; this was a vital factor in the revolution in the textile industries.After a visit to Egypt in 1799, Berthollet carried out many experiments on dyeing, seeking to place this ancient craft onto a scientific basis. His work is summed up in his Eléments de l'art de la teinture, Paris, 1791.[br]Bibliography1791, Eléments de Van de la teinture, Paris (covers his work on dyeing).Berthollet published two books of importance in the early history of physical chemistry: 1801, Recherches sur les lois de l'affinité, Paris.1803, Essai de statique chimique, Paris.Annales de Chimie.Further ReadingE.F.Jomard, 1844, Notice sur la vie et les ouvrages de Claude-Louis Berthollet, Annecy.E.Farber, 1961, Great Chemists, New York: Interscience, pp. 32–4 (includes a short biographical account).LRDBiographical history of technology > Berthollet, Claude-Louis

13 Curr, John
[br]b. 1756 Kyo, near Lanchester, or in Greenside, near Ryton-on-Tyne, Durham, Englandd. 27 January 1823 Sheffield, England[br]English coal-mine manager and engineer, inventor of flanged, cast-iron plate rails.[br]The son of a "coal viewer", Curr was brought up in the West Durham colliery district. In 1777 he went to the Duke of Norfolk's collieries at Sheffield, where in 1880 he was appointed Superintendent. There coal was conveyed underground in baskets on sledges: Curr replaced the wicker sledges with wheeled corves, i.e. small four-wheeled wooden wagons, running on "rail-roads" with cast-iron rails and hauled from the coal-face to the shaft bottom by horses. The rails employed hitherto had usually consisted of plates of iron, the flange being on the wheels of the wagon. Curr's new design involved flanges on the rails which guided the vehicles, the wheels of which were unflanged and could run on any hard surface. He appears to have left no precise record of the date that he did this, and surviving records have been interpreted as implying various dates between 1776 and 1787. In 1787 John Buddle paid tribute to the efficiency of the rails of Curr's type, which were first used for surface transport by Joseph Butler in 1788 at his iron furnace at Wingerworth near Chesterfield: their use was then promoted widely by Benjamin Outram, and they were adopted in many other English mines. They proved serviceable until the advent of locomotives demanded different rails.In 1788 Curr also developed a system for drawing a full corve up a mine shaft while lowering an empty one, with guides to separate them. At the surface the corves were automatically emptied by tipplers. Four years later he was awarded a patent for using double ropes for lifting heavier loads. As the weight of the rope itself became a considerable problem with the increasing depth of the shafts, Curr invented the flat hemp rope, patented in 1798, which consisted of several small round ropes stitched together and lapped upon itself in winding. It acted as a counterbalance and led to a reduction in the time and cost of hoisting: at the beginning of a run the loaded rope began to coil upon a small diameter, gradually increasing, while the unloaded rope began to coil off a large diameter, gradually decreasing.Curr's book The Coal Viewer (1797) is the earliest-known engineering work on railway track and it also contains the most elaborate description of a Newcomen pumping engine, at the highest state of its development. He became an acknowledged expert on construction of Newcomen-type atmospheric engines, and in 1792 he established a foundry to make parts for railways and engines.Because of the poor financial results of the Duke of Norfolk's collieries at the end of the century, Curr was dismissed in 1801 despite numerous inventions and improvements which he had introduced. After his dismissal, six more of his patents were concerned with rope-making: the one he gained in 1813 referred to the application of flat ropes to horse-gins and perpendicular drum-shafts of steam engines. Curr also introduced the use of inclined planes, where a descending train of full corves pulled up an empty one, and he was one of the pioneers employing fixed steam engines for hauling. He may have resided in France for some time before his death.[br]Bibliography1788. British patent no. 1,660 (guides in mine shafts).1789.

14 Eccles, William Henry
[br]b. 23 August 1875 Ulverston, Cumbria, Englandd. 27 April 1966 Oxford, England[br]English physicist who made important contributions to the development of radio communications.[br]After early education at home and at private school, Eccles won a scholarship to the Royal College of Science (now Imperial College), London, where he gained a First Class BSc in physics in 1898. He then worked as a demonstrator at the college and studied coherers, for which he obtained a DSc in 1901. Increasingly interested in electrical engineering, he joined the Marconi Company in 1899 to work on oscillators at the Poole experimental radio station, but in 1904 he returned to academic life as Professor of Mathematics and Physics and Department Head at South West Polytechnic, Chelsea. There he discovered ways of using the negative resistance of galena-crystal detectors to generate oscillations and gave a mathematical description of the operation of the triode valve. In 1910 he became Reader in Engineering at University College, London, where he published a paper explaining the reflection of radio waves by the ionosphere and designed a 60 MHz short-wave transmitter. From 1916 to 1926 he was Professor of Applied Physics and Electrical Engineering at the Finsbury City \& Guilds College and a private consulting engineer. During the First World War he was a military scientific adviser and Secretary to the Joint Board of Scientific Societies. After the war he made many contributions to electronic-circuit development, many of them (including the Eccles-Jordan "flip-flop" patented in 1918 and used in binary counters) in conjunction with F.W.Jordan, about whom little seems to be known. Illness forced Eccles's premature academic retirement in 1926, but he remained active as a consultant for many years.[br]Principal Honours and DistinctionsFRS 1921.

SUBJECT AREA: Paper and printing[br]b. 1690 Edinburgh, Scotlandd. 19 October 1749 Edinburgh, Scotland[br]Scottish inventor of stereotyping.[br]While in business as a goldsmith and jeweller, he came across the earliest known attempt to make stereotypes, that by Van der Meys of Leiden in the sixteenth century. He soldered types to the bases of a bed of type, but the process proved too expensive to be adopted. Ged took out a patent of privilege in 1725 to develop Mey's method, agreeing with a printer that if they could make casts of made-up pages of type they "would make a fortune". After many experiments to find a suitable metal, he arrived at an alloy similar to type metal. However, Ged's efforts to promote his stereotypes were blocked by the indifference of the printers and the opposition of the compositors. He tried his luck in London but failed again for much the same reason as in Edinburgh. Thither he returned, but he died in poverty.[br]Further ReadingJ.Nichols, 1781, Biographical Memoir of William Ged (the 1819 edition includes "Supplementary narrative of William Ged and his inventions, written by his daughter").LRD -
16 Koepe, Friedrich
SUBJECT AREA: Mining and extraction technology[br]b. 1 July 1835 Bergkamen, Westphalia, Germanyd. 12 September 1922 Bochum, Germany[br]German mining engineer, inventor of the friction winder for shaft hoisting.[br]After attending the School of Mines at Bochum, from 1862 he worked as an overseer in the coal-mining district of Ibbenbüren until he joined a mining company in the Ruhr area. There, as head of the machine shop, he was mainly concerned with sinking new shafts. In 1873 he became the Technical Director of the Hannover mine, near Bochum, which belonged to Krupp. When the shaft hoisting was to be extended to a lower level Koepe conceived the idea of applying a friction winder to the hoist instead of a drum, in order to save weight and costs. His method involved the use of an endless rope to which the cages were fixed without a safety catch. The rope passed over pulleys instead of coiling and uncoiling on a drum, and he consequently proposed to have the motor erected on top of the shaft rather than beside it, as had been the practice until then.Koepe's innovation turned out to be highly effective for hoisting heavy loads from deep shafts and was still popular in many countries in the 1990s, although the Krupp company did not accept it for a long time. He had severe personal problems with the company, and as Krupp refused to have his system patented he had to take it out in his own name in 1877. However, Krupp did not pay for the extension of the patent, nor did they pass the dossiers over to him, so the patent expired two years later. It was not until 1888 that a hoisting engine equipped with a friction winder was erected for the first time in a head gear, above the new Hannover II shaft. The following year Koepe left the Krupp company and settled as a freelance consulting engineer in Bochum; he was successful in having his system introduced by other mining companies. Ironi-cally, in 1948 the world's first four-rope winding, based on his system, was installed at the Hannover mine.[br]Further ReadingFor detailed biographical information and an assessment of his technological achievements see: H.Arnold and W.Kroker, 1977, "100 Jahre Schachtförderung nach dem System Koepe", Der Anschnitt 29:235–42.F.Lange, 1952, Die Vierseilförderung, Essen.WK -
17 Leschot, Georges Auguste
[br]b. 24 March 1800 Geneva, Switzerlandd. 4 February 1884 Geneva, Switzerland[br]Swiss clockmaker, inventor of diamond drilling.[br]By about 1843, Leschot, who was renowned for designing machines to produce parts of clocks on an industrialized scale, had gathered that the fine, deep lines he found on an Egyptian red porphyry plate must have been cut by diamonds. He thus resurrected a technology that had been largely forgotten over the centuries, when in 1862 his son, who was engaged in constructing a railway line in Italy, was confronted with the problems of tunnelling through hard rock. In Paris he developed a drilling machine consisting of a casing that rotated in a similar way to the American rope drilling method. The crown of the machine was mounted with eight black diamonds, and inside the casing a stream of water circulated continuously to flush out the mud.He took out his first patent in France in 1862, and followed it with further ones in many European countries and in America. He continued to concentrate on his watchmaker's profession and left the rights to his patents to his son. It was Leschot's ingenious idea of utilizing diamonds for drilling hard rock that was later applied in different mining processes. It influenced a series of further developments in many countries, including those of Alfred Brandt and Major Beaumont in England. In particular, the fact that the hollow casing produced a complete core was of importance for the increasing amount of petroleum prospecting in Pennsylvania after Edwin Laurentine Drake's find of 1859, where M.C.Bullock sunk the first deep well (200 m) in the world by diamond drilling in 1870. The efforts of Per Anton Crælius in Sweden made diamond drilling a success worldwide.[br]Further ReadingD.Colladon, 1884, "Notice sur les inventions mécaniques de M.G.Leschot, horloger", Archives des Sciences Physiques et Naturelles 3, XI (1):297–313 (discusses the influences of Leschot's invention on other engineers in Europe).D.Hoffmann, 1962, "Die Erfindung der Diamantbohrmaschine vor 100 Jahren", Der Anschnitt 14(1):15–19 (contains detailed biographical outlines).WKBiographical history of technology > Leschot, Georges Auguste

18 Lucas, Anthony Francis
SUBJECT AREA: Mining and extraction technology[br]b. 9 September 1855 Spalato, Dalmatia, Austria-Hungary (now Split, Croatia)d. 2 September 1921 Washington, DC, USA[br]Austrian (naturalized American) mining engineer who successfully applied rotary drilling to oil extraction.[br]A former Second Lieutenant of the Austrian navy (hence his later nickname "Captain") and graduate of the Polytechnic Institute of Graz, Lucas decided to stay in Michigan when he visited his relatives in 1879. He changed his original name, Lucie, into the form his uncle had adopted and became a naturalized American citizen at the age of 30. He worked in the lumber industry for some years and then became a consulting mechanical and mining engineer in Washington, DC. He began working for a salt-mining company in Louisiana in 1893 and became interested in the geology of the Mexican Gulf region, with a view to prospecting for petroleum. In the course of this work he came to the conclusion that the hills in this elevated area, being geological structures distinct from the surrounding deposits, were natural reservoirs of petroleum. To prove his unusual theory he subsequently chose Spindle Top, near Beaumont, Texas, where in 1899 he began to bore a first oil-well. A second drill-hole, started in October 1900, was put through clay and quicksand. After many difficulties, a layer of rock containing marine shells was reached. When the "gusher" came out on 10 January 1901, it not only opened up a new era in the oil and gas business, but it also led to the future exploration of the terrestrial crust.Lucas's boring was a breakthrough for the rotary drilling system, which was still in its early days although its principles had been established by the English engineer Robert Beart in his patent of 1884. It proved to have advantages over the pile-driving of pipes. A pipe with a simple cutter at the lower end was driven with a constantly revolving motion, grinding down on the bottom of the well, thus gouging and chipping its way downward. To deal with the quicksand he adopted the use of large and heavy casings successively telescoped one into the other. According to Fauvelle's method, water was forced through the pipe by means of a pump, so the well was kept full of circulating liquid during drilling, flushing up the mud. When the salt-rock was reached, a diamond drill was used to test the depth and the character of the deposit.When the well blew out and flowed freely he developed a preventer in order to save the oil and, even more importantly at the time, to shut the well and to control the oil flow. This assembly, patented in 1903, consisted of a combined system of pipes, valves and casings diverting the stream into a horizontal direction.Lucas's fame spread around the world, but as he had to relinquish the larger part of his interest to the oil company supporting the exploration, his financial reward was poor. One year after his success at Spindle Top he started oil exploration in Mexico, where he stayed until 1905, when he resumed his consulting practice in Washington, DC.[br]Bibliography1899, "Rock-salt in Louisiana", Transactions of the American Institution of Mining Engineers 29:462–74.1902, "The great oil-well near Beaumont, Texas", Transactions of the AmericanInstitution of Mining Engineers 31:362–74.Further ReadingR.S.McBeth, 1918, Pioneering the Gulf Coast, New York (a very detailed description of Lucas's important accomplishments in the development of the oil industry).R.T.Hill, 1903, "The Beaumont oil-field, with notes on other oil-fields of the Texas region", Transactions of the American Institution of Mining Engineers 33:363–405;Transactions of the American Institution of Mining Engineers 55:421–3 (contain shorter biographical notes).WK -
19 Sprague, Frank Julian
[br]b. 25 July 1857 Milford, Connecticut, USAd. 25 October 1934 New York, USA[br]American electrical engineer and inventor, a leading innovator in electric propulsion systems for urban transport.[br]Graduating from the United States Naval Academy, Annapolis, in 1878, Sprague served at sea and with various shore establishments. In 1883 he resigned from the Navy and obtained employment with the Edison Company; but being convinced that the use of electricity for motive power was as important as that for illumination, in 1884 he founded the Sprague Electric Railway and Motor Company. Sprague began to develop reliable and efficient motors in large sizes, marketing 15 hp (11 kW) examples by 1885. He devised the method of collecting current by using a wooden, spring-loaded rod to press a roller against the underside of an overhead wire. The installation by Sprague in 1888 of a street tramway on a large scale in Richmond, Virginia, was to become the prototype of the universally adopted trolley system with overhead conductor and the beginning of commercial electric traction. Following the success of the Richmond tramway the company equipped sixty-seven other railways before its merger with Edison General Electric in 1890. The Sprague traction motor supported on the axle of electric streetcars and flexibly mounted to the bogie set a pattern that was widely adopted for many years.Encouraged by successful experiments with multiple-sheave electric elevators, the Sprague Elevator Company was formed and installed the first set of high-speed passenger cars in 1893–4. These effectively displaced hydraulic elevators in larger buildings. From experience with control systems for these, he developed his system of multiple-unit control for electric trains, which other engineers had considered impracticable. In Sprague's system, a master controller situated in the driver's cab operated electrically at a distance the contactors and reversers which controlled the motors distributed down the train. After years of experiment, Sprague's multiple-unit control was put into use for the first time in 1898 by the Chicago South Side Elevated Railway: within fifteen years multiple-unit operation was used worldwide.[br]Principal Honours and DistinctionsPresident, American Institute of Electrical Engineers 1892–3.
