126 Bodmer, Johann Georg
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering, Railways and locomotives, Steam and internal combustion engines, Textiles, Weapons and armour[br]b. 9 December 1786 Zurich, Switzerlandd. 30 May 1864 Zurich, Switzerland[br]Swiss mechanical engineer and inventor.[br]John George Bodmer (as he was known in England) showed signs of great inventive ability even as a child. Soon after completing his apprenticeship to a local millwright, he set up his own work-shop at Zussnacht. One of his first inventions, in 1805, was a shell which exploded on impact. Soon after this he went into partnership with Baron d'Eichthal to establish a cotton mill at St Blaise in the Black Forest. Bodmer designed the water-wheels and all the machinery. A few years later they established a factory for firearms and Bodmer designed special machine tools and developed a system of interchangeable manufacture comparable with American developments at that time. More inventions followed, including a detachable bayonet for breech-loading rifles and a rifled, breech-loading cannon for 12 lb (5.4 kg) shells.Bodmer was appointed by the Grand Duke of Baden to the posts of Director General of the Government Iron Works and Inspector of Artillery. He left St Blaise in 1816 and entered completely into the service of the Grand Duke, but before taking up his duties he visited Britain for the first time and made an intensive five-month tour of textile mills, iron works, workshops and similar establishments.In 1821 he returned to Switzerland and was engaged in setting up cotton mills and other engineering works. In 1824 he went back to England, where he obtained a patent for his improvements in cotton machinery and set up a mill near Bolton incorporating his ideas. His health failing, he was obliged to return to Switzerland in 1828, but he was soon busy with engineering works there and in France. In 1833 he went to England again, first to Bolton and four years later to Manchester in partnership with H.H.Birley. In the next ten years he patented many more inventions in the fields of textile machinery, steam engines and machine tools. These included a balanced steam engine, a mechanical stoker, steam engine valve gear, gear-cutting machines and a circular planer or vertical lathe, anticipating machines of this type later developed in America by E.P. Bullard. The metric system was used in his workshops and in gearing calculations he introduced the concept of diametral pitch, which then became known as "Manchester Pitch". The balanced engine was built in stationary form and in two locomotives, but although their running was remarkably smooth the additional complication prevented their wider use.After the death of H.H.Birley in 1846, Bodmer removed to London until 1848, when he went to Austria. About 1860 he returned to his native town of Zurich. He remained actively engaged in all kinds of inventions up to the end of his life. He obtained fourteen British patents, each of which describes many inventions; two of these patents were extended beyond the normal duration of fourteen years. Two others were obtained on his behalf, one by his brother James in 1813 for his cannon and one relating to railways by Charles Fox in 1847. Many of his inventions had little direct influence but anticipated much later developments. His ideas were sound and some of his engines and machine tools were in use for over sixty years. He was elected a Member of the Institution of Civil Engineers in 1835.[br]Bibliography1845, "The advantages of working stationary and marine engines with high-pressure steam, expansively and at great velocities; and of the compensating, or double crank system", Minutes of the Proceedings of the Institution of Civil Engineers 4:372–99.1846, "On the combustion of fuel in furnaces and steam-boilers, with a description of Bodmer's fire-grate", Minutes of the Proceedings of the Institution of Civil Engineers 5:362–8.Further ReadingObituary, 1868–9, Minutes of the Proceedings of the Institution of Civil Engineers 28:573–608.H.W.Dickinson, 1929–30, "Diary of John George Bodmer, 1816–17", Transactions of the Newcomen Society 10:102–14.D.Brownlie, 1925–6, John George Bodmer, his life and work, particularly in relation to the evolution of mechanical stoking', Transactions of the Newcomen Society 6:86–110.W.O.Henderson (ed.), 1968, Industrial Britain Under the Regency: The Diaries of Escher, Bodmer, May and de Gallois 1814–1818, London: Frank Cass (a more complete account of his visit to Britain).RTS -
127 Essen, Louis
SUBJECT AREA: Horology[br]b. 6 September 1908 Nottingham, England[br]English physicist who produced the first practical caesium atomic clock, which was later used to define the second.[br]Louis Essen joined the National Physical Laboratory (NPL) at Teddington in 1927 after graduating from London University. He spent his whole working life at the NPL and retired in 1972; his research there was recognized by the award of a DSc in 1948. At NPL he joined a team working on the development of frequency standards using quartz crystals and he designed a very successful quartz oscillator, which became known as the "Essen ring". He was also involved with radio frequency oscillators. His expertise in these fields was to play a crucial role in the development of the caesium clock. The idea of an atomic clock had been proposed by I.I.Rabbi in 1945, and an instrument was constructed shortly afterwards at the National Bureau of Standards in the USA. However, this device never realized the full potential of the concept, and after seeing it on a visit to the USA Essen was convinced that a more successful instrument could be built at Teddington. Assisted by J.V.L.Parry, he commenced work in the spring of 1953 and by June 1955 the clock was working reliably, with an accuracy that was equivalent to one second in three hundred years. This was significantly more accurate than the astronomical observations that were used at that time to determine the second: in 1967 the second was redefined in terms of the value for the frequency of vibration of caesium atoms that had been obtained with this clock.[br]Principal Honours and DistinctionsFRS 1960.

128 Hjorth, Soren
SUBJECT AREA: Electricity[br]b. 13 October 1801 Vesterbygaard, Denmarkd. 28 August 1870 Copenhagen, Denmark[br]Danish engineer and inventor who first proposed the principle of the self-excited dynamo.[br]After passing a legal examination, Hjorth found employment in the state treasury in Copenhagen and in 1830 advanced to be Clerk of the Exchequer and Secretary. In 1834 he visited England to study the use of steam road and rail vehicles. Hjorth was involved in the formation of the first railway company in Denmark and became Technical Director of Denmark's first railway, a line between Copenhagen and Roskilde that opened in 1847. In 1848 he petitioned the Government for funds to visit England and have built there an electric motor of his own design with oscillating motion. This petition, supported by Hans Christian Oersted (1777–1851), was granted. A British patent was obtained for the machine, an example being exhibited at the 1851 Great Exhibition in London. Turning his attention to the generation of electricity, he conceived as early as May 1851 the dynamo electric principle with self-excitation that was incorporated in his patent in 1855. Unfortunately, Hjorth held the firm but mistaken belief that if he could use his dynamo to drive a motor he would obtain more power than was consumed in driving the dynamo. The theory of conservation of energy was being only slowly accepted at that time, and Hjorth, with little scientific training, was to be disappointed at the failure of his schemes. He worked with great perseverance and industry to the end of his life on the design of his electrical machines.[br]Bibliography11 April 1855, British patent no. 806 (Hjorth's self-excited dynamo).11 April 1855, British patent nos. 807 and 808 (reciprocating and rotary electric motors).Further ReadingS.Smith, 1912, Soren Hjorth, Copenhagen (the most detailed biography).1907, "Soren Hjorth, discoverer of the dynamo-electric principle", Electrical Engineering 1: 957–8 (a short biography).Catalogue of the 1851 Exhibition, 1851, London, pp. 1, 359–60 (for a description of Hjorth's electromagnetic engine with oscillating motion.GW
