Alexander Siemens (22 January 1847 – 16 February 1928) was a German electrical engineer.〔Obituary ''Journal of the Institution of Electrical Engineers,'' 66 (1928), 1242–3〕 Siemens was born in Hanover, then a kingdom within the German Confederation, to Gustav and Sophie Siemens. His father was a judge and a cousin of William Siemens the famous electrical engineer. He was educated in Hanover and moved to Woolwich, London in 1867 to work with at the Siemens Brothers factory.〔J. D. Scott, Siemens Brothers, 1858–1958 (1958)〕 He returned to the German Confederation in 1868 to study at the University of Berlin, interrupting his studies there to lay telegraph cables in the Middle East. These cables were to form part of the Indo-European Telegraph and much of the work was undertaken by Siemens Brothers.〔 Upon the annexation of Hanover by Prussia in 1866 following the Austro-Prussian War Siemens became a Prussian citizen and liable to conscription. He was conscripted in 1870 as a private to fight in the Franco-Prussian War where he was wounded at the Battle of Beaune-la-Rolande. It was for his actions in this battle where Prussian forces won a decisive victory over the numerically superior French army that he was awarded the Iron Cross.〔 After demobilization in 1871 he returned to the family business in Woolwich and assisted with the building of furnaces for use in steel foundries and crematoria. In 1871 Siemens was a founder member of the Society of Telegraph Engineers and Electricians (which became the Institution of Electrical Engineers in 1889) and was president of the institution twice, in 1894 and in 1904.〔(IEE biography of William Siemens )〕 His first inaugural address was an analysis of the Electric Lighting Acts of 1882 and 1888, his second advocating a wider use of the metric system.〔Rollo Appleyard ''The history of the Institution of Electrical Engineers 1871–1931'' (1939)〕 In 1875 he sailed aboard the cable ship ''Faraday'', laying several cables across the North Atlantic. In between voyages he built several furnaces for companies in the USA and Canada. Returning to the UK in 1877 he became a British citizen through naturalization in 1878. He was appointed the manager of the electric lighting division of Siemens Brothers in 1879 and was involved in the manufacture of generators, arc lamps and cables for the electric industry.〔 In 1881 he married Louisa Dodwell with whom he would have three daughters. Later that year Siemens Brothers took over a project to provide the world’s first public electricity supply in Godalming, Surrey. This project was never a viable business but the company undertook it in order to gain more experience in the lighting industry.〔 Siemens had been a director of Siemens Brothers since it became a limited company in 1880 and was made managing director in 1889, a post he was to hold until a significant reorganization replaced him, though he remained on the board of directors until his retirement in 1918. He was appointed to be a British delegate to the International Electrical Congress in 1893 and to a similar congress in Paris in 1901. In the same year as the Paris congress he was appointed to the board of the new National Physical Laboratory in Teddington.〔 He served as President of the Institution of Civil Engineers between November 1910 and November 1911.〔 〕 In retirement he lived at Westover Hall,〔(Westover Hall Hotel )〕 Milford-on-Sea, Hampshire, where he died, from heart failure, on 16 February 1928.〔(Death Certificate )〕 == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alexander Siemens」の詳細全文を読む スポンサード リンク
