Siemens' name has been adopted as the SI unit of electrical conductance, the siemens (unit).

Biography Early years Werner Siemens was born in Lenthe, today part of Gehrden, near Hanover, Germany, the fourth child (of fourteen) of a tenant farmer. He is a brother of Carl Heinrich von Siemens and William Siemens, sons of Christian Ferdinand Siemens (July 31 1787-January 16 1840) and wife Eleonore Deichmann (1792-July 8 1839). They had two more brothers, Hans Siemens (1818-1867) and Friedrich August Siemens (December 8 1828-May 24 1904), married and father to Friedrich Carl Siemens (January 6 1877-June 25 1952 in Berlin), married on May 22 1920 in Berlin to Melanie Bertha Gräfin Yorck von Wartenburg (February 1 1899 in Klein Oels-May 15 1950 in Berlin) (the parents of Heinrich Werner Andreas Siemens (born September 28 1921, Annabel Siemens (born May 3 1923), Daniela Siemens (born July 31 1926) and Peter Siemens (born November 8 1928).

Middle years Siemens left school without finishing his education, but joined the army to undertake training in engineering. Siemens invented a Telegraphy that used a needle to point to the right letter, instead of using Morse code. Based on this invention, he founded the company Telegraphen-Bauanstalt von Siemens & Halske on October 1, 1847, with the company taking occupation of its workshop on October 12.

Soon after its founding the company internationalised. One brother of Werner represented him in England (Carl Wilhelm Siemens) and another in St.Petersburg, Russia (Carl Heinrich von Siemens), each earning separate recognition in their own right. Following his industrial career, he was ennobled in 1888, becoming Werner von Siemens. He retired from his company in 1890 and died in 1892.

The company, reorganized as Siemens & Halske AG, Siemens-Schuckertwerke and – since 1966Siemens AG was later led by his brothers, his three sons Arnold von Siemens, Georg Wilhelm von Siemens and Carl Friedrich von Siemens and his nephews Hermann von Siemens, Ernst von Siemens and Peter von Siemens. Siemens AG is still one of the largest electrotechnological firms of the world.

Later years Apart from the pointer telegraph Siemens made several contributions to the development of electrical engineering and is therefore known as the founding father of the discipline in Germany. On December 14, 1877 he received German patent No. 2355 for an electromechanical "dynamic" or moving-coil transducer, which was adapted by A. L. Thuras and E. C. Wente for the Bell System in the late 1920s for use as a loudspeaker.Ed. M. D. Fagen, "A History of Engineering and Science in the Bell System: The Early Years", Bell Laboratories, 1975, P. 183. Wente's adaptation was issued US patent 1,707,545 in 1929.Siemens is also the father of the trolleybus which he initially tried and tested with his "Elektromote" on April 29, 1882.

Personal life He married twice, first in 1852 to Mathilde Duman (died July 1 1867) and second in 1869 to his relative Antonie Siemens (1840 - 1900). Children from first marriage were Arnold von Siemens and Georg Wilhelm von Siemens. Children from second marriage were Hertha von Siemens (1870 - January 5 1939), married in 1899 to Carl Dietrich Harries and Carl Friedrich von Siemens.
