101 Beau de Rochas, Alphonse Eugène
SUBJECT AREA: Steam and internal combustion engines[br]b. 1815 Franced. 1893 France[br]French railway engineer, patentee of a four-stroke cycle engine.[br]Renowned more for his ideas on technical matters than his practical deeds, Beau de Rochas was a prolific thinker. Within a few years he proposed a rail tunnel beneath the English Channel, a submarine telegraph, a new kind of drive for canal boats, the use of steel for high-pressure boilers and a method of improving the adhesion of locomotive wheels travelling the Alps.The most notable of Beau de Rochas's ideas occurred in 1862 when he was employed as Ingenieur Attaché to the Central de Chemins. With remarkable foresight, he expressed the theoretical considerations for the cycle of operations for the now widely used four-stroke cycle engine. A French patent of 1862 lapsed with a failure to pay the annuity and thus the proposals for a new motive power lapsed into obscurity. Resurrected some twenty years later, the Beau de Rochas tract figures prominently in patent litigation cases. In 1885, a German court upheld a submission by a German patent lawyer that Otto's four-stroke engine of 1876 infringed the Beau de Rochas patent. It remains a mystery why Beau de Rochas never emerged at any time to defend his claims. In France he is regarded as the inventor of the four-stroke cycle engine.[br]Principal Honours and DistinctionsSociété d'Encouragement pour l'Industrie Nationale, prize of 3000 francs, 1891.Bibliography1885, The Engineer 60:441 (an English translation of the Beau de Rochas tract).Further Reading1938, Bulletin de la Société d'Encouragement pour l'Industrie Nationale 137:209–39. 1962, Document pour l'histoire des techniques Cahier no. 2: pp. 3–42.B.Donkin, 1900, The Gas, Oil and Air Engine, London: p. 467.See also: Langen, EugenKABBiographical history of technology > Beau de Rochas, Alphonse Eugène

102 Curtiss, Glenn Hammond
SUBJECT AREA: Aerospace[br]b. 21 May 1878 Hammondsport, New York, USAd. 23 July 1930 Buffalo, New York, USA[br]American designer of aeroplanes, especially seaplanes.[br]Curtiss started his career in the bicycle business, then became a designer of motor-cycle engines, and in 1904 he designed and built an airship engine. The success of his engine led to him joining the Aerial Experimental Association (AEA), founded by the inventor Alexander Graham Bell. Working with the AEA, Curtiss built several engines and designed a biplane, June Bug, in which he won a prize for the first recorded flight of over 1 km (1,100yd) in the USA. In 1909 Curtiss joined forces with Augustus M.Herring, who had earlier flown Octave Chanute's gliders, to form the Herring-Curtiss Company. Their Gold Bug was a success and led to the Golden Flyer, in which Glenn Curtiss won the Gordon Bennett Cup at Rheims in France with a speed of 75.7 km/h (47 mph). At this time the Wright brothers accused Curtiss and the new Curtiss Aeroplane Company of infringing their patent rights, and a bitter lawsuit ensued. The acrimony subsided during the First World War and in 1929 the two companies merged to form the Curtiss-Wright Corporation.Curtiss had started experimenting with water-based aircraft in 1908, but it was not until 1911 that he managed to produce a successful float-plane. He then co-operated with the US Navy in developing catapults to launch aircraft from ships at sea. During the First World War, Curtiss produced the JN-4 Jenny trainer, which became probably his best-known design. This sturdy bi-plane continued in service long after the war and was extensively used by "barnstorming" pilots at air shows and for early mail flights. In 1919 a Navy-Curtiss NC-4 flying boat achieved the first flight across the Atlantic, having made the crossing in stages, refuelling en route. Curtiss himself, however, had little interest in aviation in his later years and turned his attention to real-estate development in Florida.[br]Principal Honours and DistinctionsRobert J.Collier Trophy 1911, 1912.

103 Dalen, Nils Gustav
[br]b. 30 November 1869 Stenstorp, Swedend. 9 December 1937 Stockholm, Sweden[br]Swedish physicist and engineer who was awarded the Nobel Prize for his "sun valve".[br]Nils Gustav Dalen is probably best known as the inventor of the solid-fuel Aga Cooker. He was confined at home for some time in the 1920s, having been blinded as the result of an accident, and found the time to consider the need for an efficient, clean, attractive-looking cooker that would be economical in fuel consumption. The resultant cooking range of 1924 was based on sound scientific principles, was simple to manage and needed a minimum of attention.The first Aga contained a cast-iron firebox enclosed in an insulated jacket of kieselguhr. The firebox was connected to cast-iron hotplates and ovens, all designed so that the heat was conducted to the various parts at precisely the correct temperatures for all types of cooking: simmering, boiling, roasting, baking and grilling. The hotplate heat was maintained at the desired temperature by way of insulated hinged covers that were lifted only when the hotplate was in use. The Aga was made in Sweden and was introduced into Britain in 1929. It was noted for being costly to purchase but inexpensive to run as no energy was wasted.Dalen is also known for his invention of the "sun valve", a device which, as required, automatically lighted or extinguished light beacons and buoys; this invention brought him the Nobel Prize for Physics in 1912.DY -
104 Johnson, Thomas
SUBJECT AREA: Textiles[br]fl. 1800s Englandd. after 1846[br]English developer of the sizing and beaming machine, and improver of the hand loom.[br]Thomas Johnson was an assistant to William Radcliffe c.1802 in his developments of the sizing machine and hand looms. Johnson is described by Edward Baines (1835) as "an ingenious but dissipated young man to whom he [Radcliffe] explained what he wanted, and whose fertile invention suggested a great variety of expedients, so that he obtained the name of the “conjuror” among his fellow-workmen". Johnson's genius, and Radcliffe's judgement and perseverance, at length produced the dressing-machine that was soon applied to power looms and made their use economic. Cotton warps had to be dressed with a starch paste to prevent them from fraying as they were being woven. Up to this time, the paste had had to be applied as the warp was unwound from the back of the loom, which meant that only short lengths could be treated and then left to dry, holding up the weaver. Radcliffe carried out the dressing and beaming in a separate machine so that weaving could proceed without interruption. Work on the dressing-machine was carried out in 1802 and patents were taken out in 1803 and 1804. These were made out in Johnson's name because Radcliffe was afraid that if his own name were used other people, particularly foreigners, would discover his secrets. Two more patents were taken out for improvements to hand looms. The first of these was a take-up motion for the woven cloth that automatically wound the cloth onto a roller as the weaver operated the loom. This was later incorporated by H.Horrocks into his own power loom design.Radcliffe and Johnson also developed the "dandy-loom", which was a more compact form of hand loom and later became adapted for weaving by power. Johnson was the inventor of the first circular or revolving temples, which kept the woven cloth at the right width. In the patent specifications there is a patent in 1805 by Thomas Johnson and James Kay for an improved power loom and another in 1807 for a vertical type of power loom. Johnson could have been involved with further patents in the 1830s and 1840s for vertical power looms and dressing-machines, which would put his death after 1846.[br]Bibliography1802, British patent no. 2,684 (dressing-machine).1803, British patent no. 2,771 (dressing-machine).1805, with James Kay, British patent no. 2,876 (power-loom). 1807, British patent no. 6,570 (vertical powerloom).Further ReadingThere is no general account of Johnson's life, but references to his work with Radcliffe may be found in A.Barlow, 1878, The History and Principles of Weaving by Hand and by Power, London; and in E.Baines, 1835, History of the Cotton Manufacture in Great Britain, London.D.J.Jeremy, 1981, Transatlantic Industrial Revolution.

105 Sauerbrun, Charles de, Baron von Drais
SUBJECT AREA: Land transport[br]b. 1785d. 1851[br]German popularizer of the first form of manumotive vehicle, the hobby-horse.[br]An engineer and agriculturalist who had to travel long distances over rough country, he evolved an improved design of velocipede. The original device appears to have been first shown in the gardens of the Palais Royal by the comte de Sivrac in 1791, a small wooden "horse" fitted with two wheels and propelled by the rider's legs thrusting alternately against the ground. It was not possible to turn the front wheel to steer the machine, a small variation from the straight being obtained by the rider leaning sideways. It is not known if de Sivrac was the inventor of the machine: it is likely that it had been in existence, probably as a child's toy, for a number of years. Its original name was the celerifière, but it was renamed the velocifère in 1793. The Baron's Draisienne was an improvement on this primitive machine; it had a triangulated wooden frame, an upholstered seat, a rear luggage seat and an armrest which took the thrust of the rider as he or she pushed against the ground. Furthermore, it was steerable. In some models there was a cordoperated brake and a prop stand, and the seat height could be adjusted. At least one machine was fitted with a milometer. Drais began limited manufacture and launched a long marketing and patenting campaign, part of which involved sending advertising letters to leading figures, including a number of kings.The Draisienne was first shown in public in April 1817: a ladies' version became available in 1819. Von Drais took out a patent in Baden on 12 January 1818 and followed with a French patent on 17 February. Three-and four-wheeled versions became available so the two men could take the ladies for a jaunt.Drais left his agricultural and forestry work and devoted his full time to the "Running Machine" business. Soon copies were being made and sold in Italy, Germany and Austria. In London, a Denis Johnson took out a patent in December 1818 for a "pedestrian curricle" which was soon nicknamed the dandy horse.[br]Further ReadingC.A.Caunter, 1955, Cycles: History and Development, London: Science Museum and HMSO.IMcNBiographical history of technology > Sauerbrun, Charles de, Baron von Drais

106 Varian, Russell Harrison
[br]b. 24 April 1898 Washington, DC, USAd. 28 July 1959 Juneau, Alaska, USA[br]American physicist who, with his brother Sigurd Varian and others, developed the klystron.[br]After attending schools in Palo Alto and Halcyon, Russell Varian went to Stanford University, gaining his BA in 1925 and his MA in 1927 despite illness and being dyslexic. His family being in need of financial help, he first worked for six months for Bush Electric in San Francisco and then for an oil company in Texas, returning to San Francisco in 1930 to join Farnsworth's Television Laboratory. After a move to Philadelphia, in 1933 the laboratory closed and Russell tried to take up a PhD course at Stanford but was rejected, so he trained as a teacher. However, although he did some teaching at Stanford it was not to be his career, for in 1935 he joined his brothers Sigurd and Eric in the setting up of a home laboratory.There, with William Hansen, a former colleague of Russell's at Stanford, they worked on the development of microwave oscillators, based on some of the latter's ideas. By 1937 they had made sufficient progress on an electron velocity-bunching tube, which they called the klystron, to obtain an agreement with the university to provide laboratory facilities in return for a share of any proceeds. By August that year they were able to produce continuous power at a wavelength of 13 cm. Clearly needing greater resources to develop and manufacture the tube, and with a possible war looming, a deal was struck with the Sperry Gyroscope Company to finance the work, which was transferred to the East Coast.In 1946, after the death of his first wife, Russell returned to Palo Alto, and in 1948 the brothers and Hansen founded Varian Associates to make microwave tubes for transmitters and linear accelerators and nuclear magnetic-resonance detectors. Subsequent research also resulted in the development of a satellite-borne magnetometer for measuring the earth's magnetic field.[br]Principal Honours and DistinctionsHonorary DSc Brooklyn Polytechnic Institute 1943.

107 Voigtländer, Peter Wilhelm Friedrich
SUBJECT AREA: Photography, film and optics[br]b. 1812 Vienna, Austria d. 1878[br]Austrian manufacturer of the first purpose-designed photographic objective; key member of a dynasty of optical instrument makers.[br]Educated at the Polytechnic Institute in Vienna, Voigtländer travelled widely before taking over the family business in 1837. The business had been founded by Voigtländer's grandfather in 1756, and was continued by his father, Johann Friedrich, the inventor of the opera glass, and by the 1830s enjoyed one of the highest reputations in Europe. When Petzval made the calculations for the first purpose-designed photographic objective in 1840, it was inevitable that he should go to Peter Voigtländer for advice. The business went on to manufacture Petzval's lens, which was also fitted to an all-metal camera of totally original design by Voigtländer.The Petzval lens was an extraordinary commercial success and Voigtländer sold specimens all over the world. Unfortunately Petzval had no formal agreement with Voigtländer and made little financial gain from his design, a fact which was to lead to dispute and separation; the Voigtländer concern continued to prosper, however. To meet the increasing demand for his products, Peter Voigtländer built a new factory in Brunswick and closed the business in Vienna. The closure is seen by at least one commentator as the death blow to Vienna's optical industry, a field in which it was once preeminent. The Voigtländer dynasty continued long after Peter's death and the name enjoyed a reputation for high-quality photographic equipment well into the twentieth century.[br]Principal Honours and DistinctionsHereditary Peerage bestowed by the Emperor of Austria 1868.Further ReadingL.W.Sipley, 1965, Photography's Great Inventors, Philadelphia (a brief biography).

Morgan (1870-1942), who was born in the State of New York, has gone down in history as the inventor of the game of volleyball, to which he originally gave the name "Mintonette".The young Morgan carried out his undergraduate studies at the Springfield College of the YMCA (Young Men's Christian Association) where he met James Naismith who, in 1891, had invented basketball. After graduating, Morgan spent his first year at the Auburn (Maine) YMCA after which, during the summer of 1896, he moved to the YMCA at Holyoke (Massachusetts) where he became Director of Physical Education. In this role he had the opportunity to establish, develop, and direct a vast programme of exercises and sports classes for male adults.His leadership was enthusiastically accepted, and his classes grew in numbers. He came to realise that he needed a certain type of competitive recreational game in order to vary his programme. Basketball, which sport was beginning to develop, seemed to suit young people, but it was necessary to find a less violent and less intense alternative for the older members.go down in history as...

114 Möller, Anton
SUBJECT AREA: Textiles[br]fl. c. 1580 Danzig, Poland[br]Polish may have been involved with the invention of the ribbon loom.[br]Around 1586, Anton Möller related that he saw in Danzig a loom on which four to six pieces of ribbon could be woven at once. Some accounts say he may have invented this loom, which required no skill to use beyond the working of a bar. The city council was afraid that a great many workers might be reduced to begging because of this invention, so they had it suppressed and the inventor strangled or drowned. It seems to have been in use in London c. 1616 and at Leiden in Holland by 1620, but its spread was handicapped both by popular rioting and by restrictive legislation. By 1621 the capacity of the loom had been increased to twenty-four ribbons, and it was later increased to fifty. It made its appearance in Lancashire around 1680 and the way the shuttles were operated could have given John Kay the inspiration for his flying shuttle.[br]Further ReadingA.Barlow, 1878, The History and Principles of Weaving by Hand and by Power, London (includes a good description and illustration of the invention).T.K.Deny and T.I.Williams, 1960, A Short History of Technology from the Earliest Timesto AD 1900, Oxford; C.Singer (ed.), 1957, A History of Technology, Vol. III, Oxford: Clarendon Press (both provide brief accounts of the introduction of the ribbon loom).RLH -
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 -
116 Yi-Xing (I-Hsing)
SUBJECT AREA: Horology[br]b. c. 672/683 Chinad. 727 China[br]Chinese astronomer and mathematician.[br]A Tantric Buddhist monk, Yi-Xing was one of the greatest astronomers and mathematicians in Chinese history. He was much influenced by Indian and therefore Hellenic astronomy. Around 725, he constructed armillary spheres with ecliptically mounted sighting tubes for taking measurements in ecliptic co-ordinates. With these instruments he took many readings of star positions and may even have discovered the proper motion of the stars. Yi-Xing's Da Yan Li Shu calendar was the result of an imperial commission to reform the calendar. It was edited the year after his death, in 728, and was officially adopted the following year. This calendar gave a nearly correct value for the irregularity of the movement of the Sun and came closer than previous attempts to calculate the day of true syzygy. Yi-Xing's method of interpolation was identical to that used by Gauss in the eighteenth century. He was also the inventor of the "water wheel link work escapement" mechanism as used later in the clock of Su Song.[br]Further ReadingJ.Needham, Science and Civilisation in China, Cambridge: Cambridge University Press, 1959–65, vols III, pp. 37–8; IV.2, pp. 471ff., 532–3.——1960, Heavenly Clockwork, pp. 17–8, 20–1, 23–5, 62, 72, 74ff., 85, 89, 94, 98, 104–5, 107, 112, 122–3, 132, 139, 151, 153, 154, 166, 175, 177, 180, 182, 187.LRD -

A machine-made cotton-face net produced by the bobbinet frame. Heathcote, about the year 1890, seems to have been the inventor of this frame, which has since had many improvements, though the principle remains. Its value depends upon the firmness of the mesh. The coarser weaves being cheaper than the fine ones. Tosca net is a good quality bobbinet, very firmly woven and very durable. -
