106 Blith, Walter
SUBJECT AREA: Agricultural and food technology[br]b. Seventeenth century Warwickshire, Englandd. Seventeenth century England[br][br]Blith was the son of a cereal and dairy farmer from the Forest of Arden. He wrote a treatise on farming which was of contemporary value in its description of drainage and water meadows, both subjects of particular relevance in the mid-seventeenth century. The book, The English Improver, contains illustrations of agricultural equipment which have become an almost obligatory inclusion in any book on agricultural history. His understanding of the plough is apparent from the text and illustrations, and his was an important step in the understanding of the scientific principles to be applied to its later design. The introduction to the book is addressed to both Houses of Parliament, and is very much an attempt to highlight and seek solutions to the problems of the agriculture of the day. In it he advocates the passing of legislation to improve agricultural practice, whether this be for the destruction of moles or for the compulsory planting of trees to replace those felled.Blith himself became a captain in the Roundhead Army during the English Civil War, and even added a dedication to Cromwell in the introduction to his second book, The English Improver Improved, published in 1652. This book contains additional information on both practice and crops, an expansion in knowledge which presumably owes something to Blith's employment as a surveyor of Crown lands between 1649 and 1650. He himself bought and farmed such land in Northamptonshire. His advice on the choice of land for particular crops and the implements of best use for that land expressed ideas in advance of their times, and it was to be almost a century before his writings were taken up and developed.[br]Bibliography1649, The English Improver; or, A New Survey of Husbandry Discovering to the Kingdom That Some Land, Both Arable and Pasture May be Advance Double or Treble, and Some five or Tenfold.1652, The English Improver Improved.Further ReadingJ.Thirsk (ed.), 1985, The Agrarian History of England and Wales, Vol. II (deals with Blith and the agriculture of his time).AP -
107 Cobbett, William
SUBJECT AREA: Agricultural and food technology[br]b. 9 March 1762 Farnham, Surrey, Englandd. 17 June 1835 Guildford, Surrey, England[br]English political writer and activist; writer on rural affairs, with a particular concern for the conditions of the agricultural worker; a keen experimental farmer who claimed responsibility for the import of Indian maize to Britain.[br]The son of a smallholder farmer and self-taught surveyor, William Cobbett was brought up to farm work from an early age. In 1783 he took employment as an attorney's clerk in London, but not finding this to his liking he travelled to Chatham with the intention of joining the Navy. A mistake in "taking the King's shilling" found him in an infantry regiment. After a year's training he was sent out to Nova Scotia and quickly gained the rank of sergeant major. On leaving the Army he brought corruption charges against three officers in his regiment, but did not press with the prosecution. England was not to his taste, and he returned to North America with his wife.In America Cobbett taught English to the growing French community displaced by the French Revolution. He found American criticism of Britain ill-balanced and in 1796 began to publish a daily newspaper under the title Porcupine's Gazetteer, in which he wrote editorials in defence of Britain. His writings won him little support from the Americans. However, on returning to London in 1800 he was offered, but turned down, the management of a Government newspaper. Instead he began to produce a daily paper called the Porcupine, which was superseded in 1802 by Cobbett's Political Register, this publication continued on a weekly basis until after his death. In 1803 he also began the Parliamentary Debates, which later merged into Hansard, the official report of parliamentary proceedings.In 1805 Cobbett took a house and 300-acre (120-hectare) farm in Hampshire, from which he continued to write, but at the same time followed the pursuits he most enjoyed. In 1809 his criticism of the punishment given to mutineers in the militia at Ely resulted in his own imprisonment. On his release in 1812 he decided that the only way to remain an independent publisher was to move back to the USA. He bought a farm at Hampstead, Long Island, New York, and published A Year's Residence in America, which contains, amongst other things, an interesting account of a farmer's year.Returning to Britain in the easier political climate of the 1820s, Cobbett bought a small seed farm in Kensington, then outside London. From there he made a number of journeys around the country, publishing accounts of them in his famous Rural Rides. His experiments and advice on the sowing and cultivation of crops, particularly turnips and swedes, and on forestry, were an important mechanism for the spread of ideas within the UK. He also claimed that he was the first to introduce the acacia and Indian maize to Britain. Much of his writing expresses a concern for the rural poor and he was firmly convinced that only parliamentary reform would achieve the changes needed. His political work and writing led to his election as Member of Parlaiment for Oldham in the 1835 election, which followed the Reform Act of 1832. However, by this time his energy was failing rapidly and he died peacefully at Normandy Farm, near Guildford, at the age of 73.[br]BibliographyCobbett's Observations on Priestley's Emigration, published in 1794, was the first of his pro-British tracts written in America. On the basis of his stay in that country he wrote A Year's Residence in America. His books on agricultural practice included Woodlands (1825) and Treatise on Cobbett's Corn (1828). Dealing with more social problems he wrote an English Grammar for the use of Apprentices, Plough Boys, Soldiers and Sailors in 1818, and Cottage Economy in 1821.Further ReadingAlbert Pell, 1902, article in Journal of the Royal Agricultural Society of England 63:1–26 (describes the life and writings of William Cobbett).James Sambrook, 1973, William Cobbett, London: Routledge (a more detailed study).AP -
108 Crælius, Per Anton
SUBJECT AREA: Mining and extraction technology[br]b. 2 November 1854 Stockholm, Swedend. 7 August 1905 Stockholm, Sweden[br]Swedish mining engineer, inventor of the core drilling technique for prospecting purposes.[br]Having completed his studies at the Technological Institute in Stockholm and the Mining School at Falun, Crælius was awarded a grant by the Swedish Jernkontoret and in 1879 he travelled to Germany, France and Belgium in order to study technological aspects of the mining, iron and steel industries. In the same year he went to the United States, where he worked with an iron works in Colorado and a mining company in Nevada. In 1884, having returned to Sweden, he obtained an appointment in the Norberg mines; two years later, he took up employment at the Ängelsberg oilmill.His mining experience had shown him the demand for a reliable, handy and cheap method of drilling, particularly for prospecting purposes. He had become acquainted with modern drilling methods in America, possibly including Albert Fauck's drilling jar. In 1886, Crælius designed his first small-diameter drill, which was assembled in one unit. Its rotating boring rod, smooth on the outside, was fixed inside a hollow mandrel which could be turned in any direction. This first drill was hand-driven, but the hydraulic version of it became the prototype for all near-surface prospecting drills in use worldwide in the late twentieth century.Between 1890 and 1900 Crælius was managing director of the Morgårdshammar mechanical workshops, where he was able to continue the development of his drilling apparatus. He successfully applied diesel engines in the 1890s, and in 1895 he added diamond crowns to the drill. The commercial exploitation of the invention was carried out by Svenska Diamantbergborrings AB, of which Crælius was a director from its establishment in 1886.[br]Further ReadingG.Glockemeier, 1913, Diamantbohrungen für Schürf-und Aufschlußarbeiten über und unter Tage, Berlin (examines the technological aspects of Crælius's drilling method).A.Nachmanson and K.Sundberg, 1936, Svenska Diamantbergborrings Aktiebolaget 1886–1936, Uppsala (outlines extensively the merits of Crælius's invention).See also: Fauvelle, Pierre-PascalWK -
109 Heathcote, John
SUBJECT AREA: Textiles[br]b. 7 August 1783 Duffield, Derbyshire, Englandd. 18 January 1861 Tiverton, Devonshire, England[br]English inventor of the bobbin-net lace machine.[br]Heathcote was the son of a small farmer who became blind, obliging the family to move to Long Whatton, near Loughborough, c.1790. He was apprenticed to W.Shepherd, a hosiery-machine maker, and became a frame-smith in the hosiery industry. He moved to Nottingham where he entered the employment of an excellent machine maker named Elliott. He later joined William Caldwell of Hathern, whose daughter he had married. The lace-making apparatus they patented jointly in 1804 had already been anticipated, so Heathcote turned to the problem of making pillow lace, a cottage industry in which women made lace by arranging pins stuck in a pillow in the correct pattern and winding around them thread contained on thin bobbins. He began by analysing the complicated hand-woven lace into simple warp and weft threads and found he could dispense with half the bobbins. The first machine he developed and patented, in 1808, made narrow lace an inch or so wide, but the following year he made much broader lace on an improved version. In his second patent, in 1809, he could make a type of net curtain, Brussels lace, without patterns. His machine made bobbin-net by the use of thin brass discs, between which the thread was wound. As they passed through the warp threads, which were arranged vertically, the warp threads were moved to each side in turn, so as to twist the bobbin threads round the warp threads. The bobbins were in two rows to save space, and jogged on carriages in grooves along a bar running the length of the machine. As the strength of this fabric depended upon bringing the bobbin threads diagonally across, in addition to the forward movement, the machine had to provide for a sideways movement of each bobbin every time the lengthwise course was completed. A high standard of accuracy in manufacture was essential for success. Called the "Old Loughborough", it was acknowledged to be the most complicated machine so far produced. In partnership with a man named Charles Lacy, who supplied the necessary capital, a factory was established at Loughborough that proved highly successful; however, their fifty-five frames were destroyed by Luddites in 1816. Heathcote was awarded damages of £10,000 by the county of Nottingham on the condition it was spent locally, but to avoid further interference he decided to transfer not only his machines but his entire workforce elsewhere and refused the money. In a disused woollen factory at Tiverton in Devonshire, powered by the waters of the river Exe, he built 300 frames of greater width and speed. By continually making inventions and improvements until he retired in 1843, his business flourished and he amassed a large fortune. He patented one machine for silk cocoon-reeling and another for plaiting or braiding. In 1825 he brought out two patents for the mechanical ornamentation or figuring of lace. He acquired a sound knowledge of French prior to opening a steam-powered lace factory in France. The factory proved to be a successful venture that lasted many years. In 1832 he patented a monstrous steam plough that is reputed to have cost him over £12,000 and was claimed to be the best in its day. One of its stated aims was "improved methods of draining land", which he hoped would develop agriculture in Ireland. A cable was used to haul the implement across the land. From 1832 to 1859, Heathcote represented Tiverton in Parliament and, among other benefactions, he built a school for his adopted town.[br]Bibliography1804, with William Caldwell, British patent no. 2,788 (lace-making machine). 1808.

110 Jablochkoff, Paul
[br]b. 14 September 1847 Serdobsk, Russiad. April 1894 St Petersburg, Russia[br]Russian military engineer and inventor of an electric "candle", the invention of which gave an immense impetus to electric lighting in the 1870s.[br]Jablochkoff studied at the Military Engineering College in St Petersburg. Having a scientific bent, he was sent to the Military Galvano Technical School. At the end of his military service in 1871 he was appointed Director General of the Moscow-Kursk telegraph lines for the Midi Railway Company. At this time he began to develop an interest in electric lighting, and in 1875 he left the Imperial Telegraph Service to devote his time exclusively to scientific pursuits. He found employment at the workshop of M Bréguet in Paris, where Gramme dynamos and Serrin arc lamps were being constructed. After some experimentation he found a means of producing a carbon arc that regulated itself without any mechanism. This lamp, the Jablochkoff candle, with two carbon rods placed parallel to each other and so close that an arc formed at the ends, could continue to burn until the rods were consumed. Plaster of Paris was used to separate the two electrodes and crumbled away as the carbon burned, thus exposing fresh carbon. These lamps were used in May 1878 in Paris to illuminate the avenue de l'Opéra, and later in Rome and London, and in essence were the first practical electric street lighting. Since there was no regulating mechanism, several candles could be placed in a single circuit. Despite inherent defects, such as the inability to restart the lamps after they were extinguished by wind or interruption of supply, they remained in use for some purposes for several years on account of their simplicity and cheapness. In 1877 Jablochkoff obtained the earliest patent to employ transformers to distribute current in an alternating-current circuit.[br]Bibliography11 September 1876, British patent no. 3,552 (Jablochkoff's candle).22 May 1877, British patent no. 1,996 (transformer or induction coil distribution).Further ReadingW.J.King, 1962, The Development of Electrical Technology in the 19th Century, Washington, DC: Smithsonian Institution, Paper 30, pp. 393–407 (a detailed account).

111 Lawrence, Richard Smith
SUBJECT AREA: Weapons and armour[br]b. 22 November 1817 Chester, Vermont, USAd. 10 March 1892 Hartford, Connecticut, USA[br]American gunsmith and inventor.[br]Richard S.Lawrence received only an elementary education and as a young man worked on local farms and later in a woodworking shop. His work there included making carpenters' and joiners' tools and he spent some of his spare time in a local gunsmith's shop. After a brief period of service in the Army, he obtained employment in 1838 with N.Kendall \& Co. of Windsor, Vermont, making guns at the Windsor prison. Within six months he was put in charge of the work, continuing in this position until 1842 when the gun-making ceased; he remained at the prison for a time in charge of the carriage shop. In 1843 he opened a gun shop in Windsor in partnership with Kendall, and the next year S.E. Robbins, a businessman, helped them obtain a contract from the Federal Government for 10,000 rifles. A new company, Robbins, Kendall \& Lawrence, was formed and a factory was built at Windsor. Three years later Kendall's share of the business was purchased by his partners and the firm became Robbins \& Lawrence. Lawrence supervised the design and production and, to improve methods of manufacture, developed new machine tools with the aid of F.W. Howe. In 1850 Lawrence introduced the lubrication of bullets, which practice ensured the success of the breech-loading rifle. Also in 1850, the company undertook to manufacture railway cars, but this involved them in a considerable financial loss. The company took to the Great Exhibition of 1851 in London, England, a set of rifles built on the interchangeable system. The interest this created resulted in a visit of some members of the British Royal Small Arms Commission to America and subsequently an order for 150 machine tools, jigs and fixtures from Robbins \& Lawrence, to be installed at the small-arms factory at Enfield. In 1852 the company contracted to manufacture Sharps rifles and carbines at a new factory to be built at Hartford, Connecticut. Lawrence moved to Hartford in 1853 to superintend the building and equipment of the plant. Shortly afterwards, however, a promised order for a large number of rifles failed to materialize and, following its earlier financial difficulties, Robbins \& Lawrence was forced into bankruptcy. The Hartford plant was acquired by the Sharps Rifle Company in 1856 and Lawrence remained there as Superintendent until 1872. From then he was for many years Superintendent of Streets in the city of Hartford and he also served on the Water Board, the Board of Aldermen and as Chairman of the Fire Board.[br]Further ReadingJ.W.Roe, 1916, English and American Tool Builders, New Haven; repub. 1926, New York; and 1987, Bradley, Ill.

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

113 Maybach, Wilhelm
[br]b. 9 February 1846 Heilbronn, Württemberg, Germanyd. 14 December 1929 Stuttgart, Germany[br]German engineer and engine designer, inventor of the spray carburettor.[br]Orphaned at the age of 10, Maybach was destined to become one of the world's most renowned engine designers. From 1868 he was apprenticed as a draughtsman at the Briiderhaus Engineering Works in Reurlingen, where his talents were recognized by Gottlieb Daimler, who was Manager and Technical Director. Nikolaus Otto had by then developed his atmospheric engine and reorganized his company, Otto \& Langen, into Gasmotorenfabrik Deutz, of which he appointed Daimler Manager. After employment at a machine builders in Karlsruhe, in 1872 Maybach followed Daimler to Deutz where he worked as a partner on the design of high-speed engines: his engines ran at up to 900 rpm, some three times as fast as conventional engines of the time. Maybach made improvements to the timing, carburation and other features. In 1881 Daimler left the Deutz Company and set up on his own as a freelance inventor, moving with his family to Bad Cannstatt; in April 1882 Maybach joined him as Engineer and Designer to set up a partnership to develop lightweight high-speed engines suitable for vehicles. A motor cycle appeared in 1885 and a modified horse-drawn carriage was fitted with a Maybach engine in 1886. Other applications to small boats, fire-engine pumps and small locomotives quickly followed, and the Vee engine of 1890 that was fitted into the French Peugeot automobiles had a profound effect upon the new sport of motor racing. In 1895 Daimler won the first international motor race and the same year Maybach became Technical Director of the Daimler firm. In 1899 Emil Jellinek, Daimler agent in France and also Austro-Hungarian consul, required a car to compete with Panhard and Levassor, who had been victorious in the Paris-Bordeaux race; he wanted more power and a lower centre of gravity, and turned to Maybach with his requirements, the 35 hp Daimler- Simplex of 1901 being the outcome. Its performance and road holding superseded those of all others at the time; it was so successful that Jellinek immediately placed an order for thirty-six cars. His daughter's name was Mercedes, after whom, when the merger of Daimler and Benz came about, the name Mercedes-Benz was adopted.In his later years, Maybach designed the engine for the Zeppelin airships. He retired from the Daimler Company in 1907.[br]Principal Honours and DistinctionsSociety of German Engineers Grashof Medal (its highest honour). In addition to numerous medals and titles from technical institutions, Maybach was awarded an honorary doctorate from the Stuttgart Institute of Technology.Further ReadingF.Schidberger, Gottlieb Daimler, Wilhelm Maybach and Karl Benz, Stuttgart: Daimler Benz AG.1961, The Annals of Mercedes-Benz Motor Vehicles and Engines, 2nd edn, Stuttgart: Daimler Benz AG.E.Johnson, 1986, The Dawn of Motoring.KAB / IMcN -
114 Singer, Isaac Merritt
[br]b. 27 October 1811 Pittstown, New York, USAd. 23 July 1875 Torquay, Devonshire, England[br]American inventor of a sewing machine, and pioneer of mass production.[br]The son of a millwright, Singer was employed as an unskilled labourer at the age of 12, but later gained wide experience as a travelling machinist. He also found employment as an actor. On 16 May 1839, while living at Lockport, Illinois, he obtained his first patent for a rock-drilling machine, but he soon squandered the money he made. Then in 1849, while at Pittsburgh, he secured a patent for a wood-and metal-carving machine that he had begun five years previously; however, a boiler explosion in the factory destroyed his machine and left him penniless.Near the end of 1850 Singer was engaged to redesign the Lerow \& Blodgett sewing machine at the Boston shop of Orson C.Phelps, where the machine was being repaired. He built an improved version in eleven days that was sufficiently different for him to patent on 12 August 1851. He formed a partnership with Phelps and G.B. Zieber and they began to market the invention. Singer soon purchased Phelps's interest, although Phelps continued to manufacture the machines. Then Edward Clark acquired a one-third interest and with Singer bought out Zieber. These two, with dark's flair for promotion and marketing, began to create a company which eventually would become the largest manufacturer of sewing machines exported worldwide, with subsidiary factories in England.However, first Singer had to defend his patent, which was challenged by an earlier Boston inventor, Elias Howe. Although after a long lawsuit Singer had to pay royalties, it was the Singer machine which eventually captured the market because it could do continuous stitching. In 1856 the Great Sewing Machine Combination, the first important pooling arrangement in American history, was formed to share the various patents so that machines could be built without infringements and manufacture could be expanded without fear of litigation. Singer contributed his monopoly on the needle-bar cam with his 1851 patent. He secured twenty additional patents, so that his original straight-needle vertical design for lock-stitching eventually included such refinements as a continuous wheel-feed, yielding presser-foot, and improved cam for moving the needle-bar. A new model, introduced in 1856, was the first to be intended solely for use in the home.Initially Phelps made all the machines for Singer. Then a works was established in New York where the parts were assembled by skilled workers through filing and fitting. Each machine was therefore a "one-off" but Singer machines were always advertised as the best on the market and sold at correspondingly high prices. Gradually, more specialized machine tools were acquired, but it was not until long after Singer had retired to Europe in 1863 that Clark made the change to mass production. Sales of machines numbered 810 in 1853 and 21,000 ten years later.[br]Bibliography12 August 1851, US patent no. 8,294 (sewing machine)Further ReadingBiographies and obituaries have appeared in Appleton's Cyclopedia of America, Vol. V; Dictionary of American Biography, Vol XVII; New York Times 25 July 1875; Scientific American (1875) 33; and National Cyclopaedia of American Biography.D.A.Hounshell, 1984, From the American System to Mass Production 1800–1932.

115 Varian, Sigurd Fergus
[br]b. 4 May 1901 Syracuse, New York, USAd. 18 October 1961 Puerto Vallarta, Mexico[br]American electrical engineer who, with his brother Russell, developed the klystron microwave tube.[br]Sigurd Varian left school in 1920 and entered California Polytechnic to study engineering, but he soon dropped out and trained as an electrician, taking up employment with the Southern Californian Edison Company. As a result of working on an airfield he developed an interest in flying. He took lessons and in 1924 bought a First World War biplane and became a "barnstorming" pilot, giving flying displays and joy-rides, etc., to earn his living. Beset by several prolonged bouts of tuberculosis, he used his periods of recuperation to study aerial navigation and to devise navigation instruments. In 1929 he took a permanent job as a pilot for Pan American in Mexico, but in 1935 he went to California to work on electron tubes with his younger brother, Eric. They were soon joined by Russell, and with William Hansen they developed the klystron. For details of this part of his life and the founding of Varian Associates, see under Russell Varian. In later years, his health increasingly poor, he lived in semi-retirement in Mexico, where he died in a plane crash while flying himself home.[br]Principal Honours and DistinctionsFranklin Institute Medal.Bibliography1939, with R.S.Varian, "High frequency oscillator and amplifier", Journal of Applied Physics 10:321 (describes the klystron).Further ReadingJ.R.Pierce, 1962, "History of the microwave tube art", Proceedings of the Institute of Radio Engineers 979 (provides background to development of the klystron).D.Varian, 1983, The Inventor and the Pilot (biographies of the brothers).KF
