41 Kurtz, Thomas E.
SUBJECT AREA: Electronics and information technology[br]b. USA[br]American mathematician who, with Kemeny developed BASIC, a high-level computer language.[br]Kurtz took his first degree in mathematics at the University of California in Los Angeles (UCLA), where he also gained experience in numerical methods as a result of working in the National Bureau of Standards Institute for Numerical Analysis located on the campus. In 1956 he obtained a PhD in statistics at Princeton, after which he took up a post as an instructor at Dartmouth College in Hanover, New Hampshire. There he found a considerable interest in computing was already in existence, and he was soon acting as the Dartmouth contact with the New England Regional Computer Center at Massachusetts Institute of Technology, an initiative partly supported by IBM. With Kemeny, he learned the Share Assembly Language then in use, but they were concerned about the difficulty of programming computers in assembly language and of teaching it to students and colleagues at Dartmouth. In 1959 the college obtained an LGP-30 computer and Kurtz became the first Director of the Dartmouth Computer Center. However, the small memory (4 k) of this 30-bit machine precluded its use with the recently available high-level language Algol 58. Therefore, with Kemeny, he set about developing a simple language and operating system that would use simple English commands and be easy to learn and use. This they called the Beginners All-purpose Symbolic Instruction Code (BASIC). At the same time they jointly supervised the design and development of a time-sharing system suitable for college use, so that by 1964, when Kurtz became an associate professor of mathematics, they had a fully operational BASIC system; by 1969 a sixth version was already in existence. In 1966 Kurtz left Dartmouth to become a Director of the Kiewit Computer Center, and then, in 1975, he became a Director of the Office of Academic Computing; in 1978 he returned to Dartmouth as Professor of Mathematics. He also served on various national committees.[br]Bibliography1964, with J.G.Kemeny, BASIC Instruction Manual: Dartmouth College (for details of the development of BASIC etc.).1968, with J.G.Kemeny "Dartmouth time-sharing", Science 223.Further ReadingR.L.Wexelblat, 1981, History of Programming Languages, London: Academic Press (a more general view of the development of computer languages).KF -

43 management education
HRformal instruction in the principles and techniques of management, and in related subjects, leading to a qualification. Management education strives to develop management knowledge, understanding, and competence through classroom or distance-based methods. Management education is a main component of management development, and differs from management training in that the latter may exploit any one of a variety of formal or informal methods, tends to be focused on a specific skill, and does not result directly in a formal qualification. -
44 Stuart, Herbert Akroyd
SUBJECT AREA: Steam and internal combustion engines[br]b. 1864 Halifax, Englandd. 1927 Perth, Australia[br]English inventor of an oil internal-combustion engine.[br]Stuart's involvement with engines covered a period of less than ten years and was concerned with a means of vaporizing the heavier oils for use in the so-called oil engines. Leaving his native Yorkshire for Bletchley in Buckinghamshire, Stuart worked in his father's business, the Bletchley Iron and Tin Plate works. After finishing grammar school, he worked as an assistant in the Mechanical Engineering Department of the City and Guilds of London Technical College. He also formed a connection with the Finsbury Technical College, where he became acquainted with Professor William Robinson, a distinguished engineer eminent in the field of internal-combustion engines.Resuming work at Bletchley, Stuart carried out experiments with engines. His first patent was concerned with new methods of vaporizing the fuel, scavenging systems and improvement of speed control. Two further patents, in 1890, specified substantial improvements and formed the basis of later engine designs. In 1891 Stuart joined forces with R.Hornsby and Sons of Grantham, a firm founded in 1815 for the manufacture of machinery and steam engines. Hornsby acquired all rights to Stuart's engine patents, and their superior technical resources ensured substantial improvements to Stuart's early design. The Hornsby-Ackroyd engines, introduced in 1892, were highly successful and found wide acceptance, particularly in agriculture. With failing health, Stuart's interest in his engine work declined, and in 1899 he emigrated to Australia, where in 1903 he became a partner in importing gas engines and gas-producing plants. Following his death in 1927, under the terms of his will he was interred in England; sadly, he also requested that all papers and materials pertaining to his engines be destroyed.[br]BibliographyJuly 1886, British patent no. 9,866 (fuel vapourization methods, scavenging systems and improvement of speed control; the patent describes Stuart as Mechanical Engineer of Bletchley Iron Works).1890, British patent no. 7,146 and British patent no. 15,994 (describe a vaporizing chamber connected to the working cylinder by a small throat).Further ReadingD.Clerk, 1895, The Gas and Oil Engine, 6th edn, London, pp. 420–6 (provides a detailed description of the Hornsby-Ackroyd engine and includes details of an engine test).T.Hornbuckle and A.K.Bruce, 1940, Herbert Akroyd Stuart and the Development of the Heavy Oil Engine, London: Diesel Engine Users'Association, p. 1.KAB -
45 Welte, Edwin
SUBJECT AREA: Recording[br]b. 1876 Germanyd. after 1925[br]German instrument maker who developed piano-music recording methods for reproducing pianos.[br]He was the third generation of the Freiburg (Germany) firm of M.Welte \& Soehne, music box and orchestrion manufacturers, founded in 1832, and was made a partner in 1901. He was the driving force behind the development and refinement of the reproducing piano, which had an upper-class market from 1905 to c. 1925. With his partner and brother-in-law Karl Bockisch, he also developed recording methods that made it possible to distribute perforated paper rolls representing a reasonably accurate representation of the performance of famous soloists. This is a principle for recording and replay that is totally different from the mechanical recording principle, and at that time the quality was generally regarded as higher than that of mechanical reproduction. However, because of the possibilities of editing, the source value may be less certain. Welte's contribution was the first commercial use of a coded representation of live performances. The Welte patents were licensed to several other player-piano manufacturers.[br]BibliographyGerman patent no. 162,708 (controlling the dynamics of reproduction).Further ReadingQ.D.Bowers, 1972, Encyclopedia of Automatic Musical Instruments, New York: Vestal Press, pp. 319–38 (a good if somewhat uneven account of the Welte involvement in the reproduction of recorded sound).GB-N -

53 Birdseye, Clarence
SUBJECT AREA: Agricultural and food technology[br]b. 9 December 1886 Brooklyn, New York, USAd. 7 October 1956 USA[br]American inventor of the fast-freezing method of food preservation.[br]Clarence Birdseye went to high school at Montclair in New Jersey, and from there to Amherst College between 1906 and 1910. He became a field naturalist on the US Department of Agriculture's survey of 1910 to 1912, and during the following five years worked as a fur trader. He was the Purchasing Agent for the US Navy Corps between 1917 and 1919, and acted as Assistant to the President of the US Fisherman's Association between 1920 and 1922.Birdseye was a keen fisherman, and during his time in Labrador learnt how to fast-freeze his catch in the wind. He formed the Birdseye Seafood Company in 1923 and pioneered the development of quick-freezing methods for the preservation of dressed seafood. His first company went bankrupt, but he quickly formed the General Seafoods Corporation. He filed his first patent in 1924 for the plate freezer, and in the late 1920s developed the double belt freezer. In 1929 Birdseye's company was bought out for $22 million, Birdseye himself receiving $1 million. He was an active member of the American Fisherman's Society, the American Society of Refrigeration Engineers, the American Society of Mechanical Engineers, the American Society of Mammalogists and the Institute of Food Technologists.[br]Principal Honours and DistinctionsNutrition Foundation Stephen M.Babcock Award 1949.Further ReadingW.H.Clark and J.Moynahan, Famous Leaders of Industry (gives a brief account of Birdseye's life).1982, Frozen Food Age (August) (an account of the development of the industry he created).AP -
54 Clark, Edward
SUBJECT AREA: Domestic appliances and interiors[br]fl. 1850s New York State, USA[br]American co-developer of mass-production techniques at the Singer sewing machine factory.[br]Born in upstate New York, where his father was a small manufacturer, Edward Clark attended college at Williams and graduated in 1831. He became a lawyer in New York City and from then on lived either in the city or on his rural estate near Cooperstown in upstate New York. After a series of share manipulations, Clark acquired a one-third interest in Isaac M. Singer's company. They soon bought out one of Singer's earlier partners, G.B.Zeiber, and in 1851, under the name of I.M.Singer \& Co., they set up a permanent sewing machine business with headquarters in New York.The success of their firm initially rested on marketing. Clark introduced door-to-door sales-people and hire-purchase for their sewing machines in 1856 ($50 cash down, or $100 with a cash payment of $5 and $3 a month thereafter). He also trained women to demonstrate to potential customers the capabilities of the Singer sewing machine. At first their sewing machines continued to be made in the traditional way, with the parts fitted together by skilled workers through hand filing and shaping so that the parts would fit only onto one machine. This resembled European practice rather than the American system of manufacture that had been pioneered in the armouries in that country. In 1856 Singer brought out their first machine intended exclusively for home use, and at the same time manufacturing capacity was improved. Through increased sales, a new factory was built in 1858–9 on Mott Street, New York, but it soon became inadequate to meet demand.In 1863 the Singer company was incorporated as the Singer Manufacturing Co. and began to modernize its production methods with special jigs and fixtures to help ensure uniformity. More and more specialized machinery was built for making the parts. By 1880 the factory, then at Elizabethport, New Jersey, was jammed with automatic and semi-automatic machine tools. In 1882 the factory was producing sewing machines with fully interchangeable parts that did not require hand fitting in assembly. Production rose from 810 machines in 1853 to half a million in 1880. A new family model was introduced in 1881. Clark had succeeded Singer, who died in 1875, as President of the company, but he retired in 1882 after he had seen through the change to mass production.[br]Further ReadingNational Cyclopaedia of American Biography.D.A.Hounshell, 1984, From the American System to Mass Production, 1800–1932.

55 Crookes, Sir William
SUBJECT AREA: Electricity[br]b. 17 June 1832 London, Englandd. 4 April 1919 London, England[br]English chemist and physicist who carried out studies of electrical discharges and cathode rays in rarefied gases, leading to the development of the cathode ray tube; discoverer of the element thallium and the principle of the Crookes radiometer.[br]Crookes entered the Royal College of Chemistry at the age of 15, and from 1850 to 1854 held the appointment of Assistant at the college. In 1854 he became Superintendent of the Meteorological Department at the Radcliffe Observatory in Oxford. He moved to a post at the College of Science in Chester the following year. Soon after this he inherited a large fortune and set up his own private laboratory in London. There he studied the nature of electrical discharges in gases at low pressure and discovered the dark space (later named after him) that surrounds the negative electrode, or cathode. He also established that the rays produced in the process (subsequently shown by J.J.Thompson to be a stream of electrons) not only travelled in straight lines, but were also capable of producing heat and/or light upon impact with suitable anode materials. Using a variety of new methods to investigate these "cathode" rays, he applied them to the spectral analysis of compounds of selenium and, as a result, in 1861 he discovered the element thallium, finally establishing its atomic weight in 1873. Following his discovery of thallium, he became involved in two main lines of research: the properties of rarified gases, and the investigation of the elements of the "rare earths". It was also during these experiments that he discovered the principle of the Crookes radiometer, a device in which light is converted into rotational motion and which used to be found frequently in the shop windows of English opticians. Also among the fruits of this work were the Crookes tubes and the development of spectacle lenses with differential ranges of radiational absorption. In the 1870s he became interested in spiritualism and acquired a reputation for his studies of psychic phenomena, but at the turn of the century he returned to traditional scientific investigations. In 1892 he wrote about the possibility of wireless telegraphy. His work in the field of radioactivity led to the invention of the spinthariscope, an early type of detector of alpha particles. In 1900 he undertook investigations into uranium which led to the study of scintillation, an important tool in the study of radioactivity.While the theoretical basis of his work has not stood the test of time, his material discoveries, observations and investigations of new facts formed a basis on which others such as J.J. Thomson were to develop subatomic theory. His later involvement in the investigation of spiritualism led to much criticism, but could be justified on the basis of a belief in the duty to investigate all phenomena.[br]Principal Honours and DistinctionsKnighted 1897.

56 Dunlop, John Boyd
SUBJECT AREA: Land transport[br]b. 5 February 1840 Dreghorn, Ayrshire, Scotlandd. 23 October 1921 Ballsbridge, Dublin, Ireland[br]Scottish inventor and pioneer of the pneumatic tyre.[br]Reared in an agricultural community, Dunlop became a qualified veterinary surgeon and practised successfully in Edinburgh and then in Belfast when he moved there in 1867. In October 1887, Dunlop's 9-year-old son complained of the rough ride he experienced with his tricycle over the cobbled streets of Belfast. Dunlop devised and fitted rubber air tubes, held on to a wooden ring by tacking a linen covering which he fixed around the wheels of the tricycle. A marked improvement in riding quality was noted. After further development, a new tricycle was ordered, with the new airtube wheels. This was so successful that Dunlop applied for a patent on 23 July 1889, granted on 7 December. With tyres made in Edinburgh to his specification, bicycles were manufactured by Edlin \& Co. of Belfast and put on sale complete with pneumatic tyres. The successful performance of a racing bicycle thus equipped inspired an unsuccessful competitor, William Harvey de Cros, who had used a solid-tyred machine, to take an interest in Dunlop's invention. With Dunlop, he refloated a company in Dublin, the Pneumatic Tyre \& Booth's Cycle Agency. Dunlop made over his patents, for the tyre, valves, rims and fixing methods, to Du Cros and took shares in the company. Although he was involved in it for many years, it was Du Cros who steered the company through several struggles to success.The pneumatic tyre revolutionized cycling and made possible the success of the motor vehicle, although Dunlop did not profit greatly from his invention. After the sale of the company in 1896, to E.T.Hooley for $3 million, he took no further part in the development of the pneumatic tyre. The company went on to become the great Dunlop Rubber Company.[br]Further ReadingJ.McClintock, 1923, History of the Pneumatic Tyre, Belfast (written by Dunlop's daughter, who based the book on her father's reminiscences).LRD -
57 Johnson, Clarence Leonard (Kelly)
SUBJECT AREA: Aerospace[br]b. 27 February 1910 Michigan, USAd. 21 December 1990 Burbank County, California, USA[br]American aircraft designer responsible for many outstanding Lockheed aircraft over a period of almost forty-eight years.[br]The large and successful Lockheed Aircraft Corporation grew out of a small company founded by Allan and Malcolm Loughhead (pronounced "Lockheed") in 1913. The company employed many notable designers such as Jack Northrop, Jerry Vultee and Lloyd Stearman, but the most productive was "Kelly" Johnson. After studying aeronautical engineering at the University of Michigan, Johnson joined Lockheed in 1933 and gained experience in all the branches of the design department. By 1938 he had been appointed Chief Research Engineer and became involved with the design of the P-38 Lightning twin-boom fighter and the Constellation airliner. In 1943 he set up a super-secret research and development organization called Advanced Development Projects, but this soon became known as the "Skunk Works": the name came from a very mysterious factory which made potions from skunks in the popular comic strip Li'lAbner. The first aircraft designed and built by Johnson's small hand-picked team was the XP-80 Shooting Star prototype jet fighter, which was produced in just 143 days: it became the United States' first production jet fighter. At this stage the Skunk Works produced a prototype, then the main Lockheed factories took over the production run. The F-104 Starfighter and the C-130 Hercules transport were produced in this way and became widely used in many countries. In 1954 work began on the U-2 reconnaissance aircraft which was so secret that production was carried out within the Skunk Works. This made the headlines in 1960 when one was shot down over Russia. Probably the most outstanding of Johnson's designs was the SR-71 Blackbird of 1964, a reconnaissance aircraft capable of flying at Mach 3 (three times the speed of sound). Johnson was not only a great designer, he was also an outstanding manager, and his methods—including his "14 Rules"—have been widely followed. He retired from the Lockheed board in 1980, having been involved in the design of some forty aircraft.[br]Principal Honours and DistinctionsNational Medal of Freedom (the highest United States award for a civilian) 1964.Further ReadingObituary, 1991, Aerospace (Royal Aeronautical Society) (March).B.R.Rich, 1989, "The Skunk Works" management style: it's no secret', Aerospace (Royal Aeronautical Society) (March) (Rich was Johnson's successor).Details of Lockheed aircraft can be found in several publications, e.g.: R.J.Francillon, 1982, Lockheed Aircraft since 1913, London.JDSBiographical history of technology > Johnson, Clarence Leonard (Kelly)

59 Maxwell, James Clerk
[br]b. 13 June 1831 Edinburgh, Scotlandd. 5 November 1879 Cambridge, England[br]Scottish physicist who formulated the unified theory of electromagnetism, the kinetic theory of gases and a theory of colour.[br]Maxwell attended school at the Edinburgh Academy and at the age of 16 went on to study at Edinburgh University. In 1850 he entered Trinity College, Cambridge, where he graduated four years later as Second Wrangler with the award of the Smith's Prize. Two years later he was appointed Professor at Marischal College, Aberdeen, where he married the Principal's daughter. In 1860 he moved to King's College London, but on the death of his father five years later, Maxwell returned to the family home in Scotland, where he continued his researches as far as the life of a gentleman farmer allowed. This rural existence was interrupted in 1874 when he was persuaded to accept the chair of Cavendish Professor of Experimental Physics at Cambridge. Unfortunately, in 1879 he contracted the cancer that brought his brilliant career to an untimely end. While at Cambridge, Maxwell founded the Cavendish Laboratory for research in physics. A succession of distinguished physicists headed the laboratory, making it one of the world's great centres for notable discoveries in physics.During the mid-1850s, Maxwell worked towards a theory to explain electrical and magnetic phenomena in mathematical terms, culminating in 1864 with the formulation of the fundamental equations of electromagnetism (Maxwell's equations). These equations also described the propagation of light, for he had shown that light consists of transverse electromagnetic waves in a hypothetical medium, the "ether". This great synthesis of theories uniting a wide range of phenomena is worthy to set beside those of Sir Isaac Newton and Einstein. Like all such syntheses, it led on to further discoveries. Maxwell himself had suggested that light represented only a small part of the spectrum of electromagnetic waves, and in 1888 Hertz confirmed the discovery of another small part of the spectrum, radio waves, with momentous implications for the development of telecommunication technology. Maxwell contributed to the kinetic theory of gases, which by then were viewed as consisting of a mass of randomly moving molecules colliding with each other and with the walls of the containing vessel. From 1869 Maxwell applied statistical methods to describe the molecular motion in mathematical terms. This led to a greater understanding of the behaviour of gases, with important consequences for the chemical industry.Of more direct technological application was Maxwell's work on colour vision, begun in 1849, showing that all colours could be derived from the three primary colours, red, yellow and blue. This enabled him in 1861 to produce the first colour photograph, of a tartan. Maxwell's discoveries about colour vision were quickly taken up and led to the development of colour printing and photography.[br]BibliographyMost of his technical papers are reprinted in The Scientific Papers of J.Clerk Maxwell, 1890, ed. W.D.Niven, Cambridge, 2 vols; reprinted 1952, New York.Maxwell published several books, including Theory of Heat, 1870, London (1894, 11th edn, with notes by Lord Rayleigh) and Theory of Electricity and Magnetism, 1873, Oxford (1891, ed. J.J.Thomson, 3rd edn).Further ReadingL.Campbell and W.Garnett, 1882, The Life of James Clerk Maxwell, London (the standard biography).J.J.Thomson (ed.), 1931, James Clerk Maxwell 1831–1931, Cambridge.

60 Pääbo, Max
SUBJECT AREA: Textiles[br]b. Estonia fl. 1950s Sweden[br]Estonian inventor of one of the most successful looms, in which the weft is sent across the warp by a jet of air.[br]The earliest patent for using a jet of air to propel a shuttle across a loom was granted to J.C. Brooks in 1914. A different method was tried by E.H.Ballou in 1929, but the really important patent was taken out by Max Pääbo, a refugee from Estonia. He exhibited his machine in Sweden in 1951, weaving cotton cloth 80 cm (31 1/2 in.) wide at a speed of 350 picks per minute, but it was not widely publicized until 1954. One shown in Manchester in 1958 ran at 410 picks per minute while weaving 90 cm (35 1/2 in.) cloth. His looms were called "Maxbo" after him. They had no shuttle; instead a jet of air drove a measured amount of weft drawn from a supply package across the warp threads. Efficient control of the airstream was the main reason for its success; not only was weaving much quicker, but it was also much quieter than traditional methods, and as the warp was nearly vertical the looms took up little space. Manufacture of these looms in Sweden ceased in 1962, but development continued in other countries.[br]Further ReadingJ.J.Vincent, 1980, Shuttle less Looms, Manchester (a good account of the development of modern looms).RLH
