5 Behr, Fritz Bernhard
[br]b. 9 October 1842 Berlin, Germanyd. 25 February 1927[br]German (naturalized British in 1876) engineer, promoter of the Lartigue monorail system.[br]Behr trained as an engineer in Britain and had several railway engineering appointments before becoming associated with C.F.M.-T. Lartigue in promoting the Lartigue monorail system in the British Isles. In Lartigue's system, a single rail was supported on trestles; vehicles ran on the rail, their bodies suspended pannier-fashion, stabilized by horizontal rollers running against light guide rails fixed to the sides of the trestles. Behr became Managing Director of the Listowel \& Ballybunion Railway Company, which in 1888 opened its Lartigue system line between those two places in the south-west of Ireland. Three locomotives designed by J.T.A. Mallet were built for the line by Hunslet Engine Company, each with two horizontal boilers, one either side of the track. Coaches and wagons likewise were in two parts. Technically the railway was successful, but lack of traffic caused the company to go bankrupt in 1897: the railway continued to operate until 1924.Meanwhile Behr had been thinking in terms far more ambitious than a country branch line. Railway speeds of 150mph (240km/h) or more then lay far in the future: engineers were uncertain whether normal railway vehicles would even be stable at such speeds. Behr was convinced that a high-speed electric vehicle on a substantial Lartigue monorail track would be stable. In 1897 he demonstrated such a vehicle on a 3mile (4.8km) test track at the Brussels International Exhibition. By keeping the weight of the motors low, he was able to place the seats above rail level. Although the generating station provided by the Exhibition authorities never operated at full power, speeds over 75mph (120 km/h) were achieved.Behr then promoted the Manchester-Liverpool Express Railway, on which monorail trains of this type running at speeds up to 110mph (177km/h) were to link the two cities in twenty minutes. Despite strong opposition from established railway companies, an Act of Parliament authorizing it was made in 1901. The Act also contained provision for the Board of Trade to require experiments to prove the system's safety. In practice this meant that seven miles of line, and a complete generating station to enable trains to travel at full speed, must be built before it was known whether the Board would give its approval for the railway or not. Such a condition was too severe for the scheme to attract investors and it remained stillborn.[br]Further ReadingH.Fayle, 1946, The Narrow Gauge Railways of Ireland, Greenlake Publications, Part 2, ch. 2 (describes the Listowel \& Ballybunion Railway and Behr's work there).D.G.Tucker, 1984, "F.B.Behr's development of the Lartigue monorail", Transactions ofthe Newcomen Society 55 (covers mainly the high speed lines).See also: Brennan, LouisPJGR -
6 Jobard, Jean-Baptiste-Ambroise Marcelin
SUBJECT AREA: Mining and extraction technology[br]b. 14 May 1792 Baissey, Haute-Marne, Franced. 27 October 1861 Brussels, Belgium[br]French technologist, promoter of Belgian industry.[br]After attending schools in Langres and Dijon, Jobard worked in Groningen and Maastricht as a cadastral officer from 1811 onwards. After the Netherlands had been constituted as a new state in 1814, he became a Dutch citizen in 1815 and settled in Brussels. In 1825, when he had learned of the invention of lithography by Alois Senefelder, he retired and established a renowned lithographic workshop in Belgium, with considerable commercial profit. After the political changes which led to the separation of Belgium from the Netherlands in 1830, he devoted his activities to the progress of science and industry in this country, in the traditional idea of enlightenment. His main aim was to promote all branches of the young economy, to which he contributed with ceaseless energy. He cultivated especially the transfer of technology in many articles he wrote on his various journeys, such as to Britain, France, Germany and Switzerland, and he continued to do so when he became the Director of the Museum of Industry in Brussels in 1841, editing its Bulletin until his death. Jobard, as a member of societies for the encouragement of arts and industry in many countries, published on almost any subject and produced many inventions. Being a restless character by nature, and having, in addition, a strong attitude towards designing and constructing, he also contributed to mining technology in 1828 when he was the first European to practise successfully the Chinese method of rope drilling near Brussels.[br]Bibliography1840, Plan d'organisation du Musée de l'industrie, présenté au Ministre de l'interieur, Brussels.1844, Machines à vapeur, arrêtes et instructions, Brussels.1846, Comment la Belgique peut devenir industrielle, à propos de la Société d'exportation, Brussels.considérées comme blason de l'industrie et du commerce, dédié à la Société des inventeurs et protecteurs de l'industrie, Brussels.1855, Discours prononcé à l'assemblée des industriels réunis pour l'adoption de la marque obligatoire, Paris.Further ReadingH.Blémont, 1991, article in Dictionnaire de biographie française, Paris, pp. 676–7 (for a short account of his life).A.Siret, 1888–9, article in Biographie nationale de belgique, Vol. X, Brussels, col. 494– 500 (provides an impressive description of his restless character and a selected bibliography of his many publications.T.Tecklenburg, 1900, Handbuch der Tiefbohrkunde, 2nd edn, Vol. IV, Berlin, pp. 7–8 (contains detailed information on his method of rope drilling).WKBiographical history of technology > Jobard, Jean-Baptiste-Ambroise Marcelin
