Ernst Werner Siemens (von Siemens from 1888; English: /ˈsiːm.ənz/ SEEM-ənz;[1] German: [ˈziːməns, -mɛns];[2] 13 December 1816 – 6 December 1892) was a German electrical engineer, inventor and industrialist. Siemens's name has been adopted as the SI unit of electrical conductance, the siemens. He founded the electrical and telecommunications conglomerate Siemens and invented the electric tram, trolley bus, electric locomotive and electric elevator.

Biography

[edit]

Early years

[edit]

Ernst Werner Siemens was born in Lenthe,[3] today part of Gehrden, near Hannover, in the Kingdom of Hanover in the German Confederation, the fourth child (of fourteen) of Christian Ferdinand Siemens (31 July 1787 – 16 January 1840) and wife Eleonore Deichmann (1792 – 8 July 1839). His father was a tenant farmer of the Siemens family, an old family of Goslar, documented since 1384. Carl Heinrich von Siemens and Carl Wilhelm Siemens were his brothers.

Middle years

[edit]

After finishing school, Siemens intended to study at the Bauakademie Berlin.[4] However, since his family was highly indebted and thus could not afford to pay the tuition fees, he chose to join the Prussian Military Academy's School of Artillery and Engineering, between the years 1835–1838, instead, where he received his officers training.[5] Siemens was thought of as a good soldier, receiving various medals[citation needed], and contributing to the invention of electrically-charged sea mines, which were used to combat a Danish blockade of Kiel during the First Schleswig War.[6][7]

Upon returning home from war, he chose to work on perfecting technologies that had already been established and eventually became known worldwide for his advances in various technologies. In 1843 he sold the rights to his first invention to Elkington of Birmingham.[8] Siemens invented a telegraph that used a needle to point to the right letter, instead of using Morse code.[9] Based on this invention, he founded the company Telegraphen-Bauanstalt von Siemens & Halske on 1 October 1847, with the company opening a workshop on 12 October.[10]

The company was internationalised soon after its founding. One brother of Werner represented him in England (Sir William Siemens) and another in St. Petersburg, Russia (Carl von Siemens), each earning recognition. Following his industrial career, he was ennobled in 1888, becoming Werner von Siemens. He retired from his company in 1890 and died in 1892 in Berlin.[citation needed]

The company, reorganized as Siemens & Halske AG, Siemens-Schuckertwerke and – since 1966 – Siemens AG was later led by his brother Carl, his sons Arnold, Wilhelm, and Carl Friedrich, his grandsons Hermann and Ernst and his great-grandson Peter von Siemens. Siemens AG is one of the largest electrotechnological firms in the world. The von Siemens family still owns 6% of the company shares (as of 2013) and holds a seat on the supervisory board, being the largest shareholder.[citation needed]

Later years

[edit]

Apart from the pointer telegraph, Siemens made sufficient contributions to the development of electrical engineering that he became known as the founding father of the discipline in Germany. He built the world's first electric passenger train in 1879,[11] and the first electric elevator in 1880.[12] His company produced the tubes with which Wilhelm Conrad Röntgen investigated x-rays. He claimed invention of the dynamo although others invented it earlier. On 14 December 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.[13] Wente's adaptation was issued U.S. patent 1,707,545 in 1929.

In May 1881, Siemens & Halske inaugurated the world's first electric tram service, in the Berlin suburb of Groß-Lichterfelde.[14] Siemens is also the father of the trolleybus, which he initially tried and tested on 29 April 1882, using his "Elektromote".

Personal life

[edit]

He was married twice: first in 1852 to Mathilde Drumann (died 1 July 1867), the daughter of the historian Wilhelm Drumann; second in 1869 to his relative Antonie Siemens (1840–1900). His children from first marriage were Arnold von Siemens and Georg Wilhelm von Siemens, and his children from second marriage were Hertha von Siemens (1870 – 5 January 1939), married in 1899 to Carl Dietrich Harries, and Carl Friedrich von Siemens.

Siemens was an advocate of social democracy,[15] and he hoped that industrial development would not be used in favour of capitalism, stating:

A number of great factories in the hands of rich capitalists, in which "slaves of work" drag out their miserable existence, is not, therefore, the goal of the development of the age of natural science, but a return to individual labour, or where the nature of things demands it, the carrying on of common workshops by unions of workmen, who will receive a sound basis only through the general extension of knowledge and civilization, and through the possibility of obtaining cheaper capital.[16]

He also rejected the claim that science leads to materialism, stating instead:

Equally unfounded is the complaint that the study of science and the technical application of the forces of nature gives to mankind a thoroughly material direction, makes them proud of their knowledge and power, and alienates ideal endeavours. The deeper we penetrate into the harmonious action of natural forces regulated by eternal unalterable laws, and yet so thickly veiled from our complete comprehension, the more we feel on the contrary moved to humble modesty, the smaller appears to us the extent of our knowledge, the more active is our endeavour to draw more from the inexhaustible fountain of knowledge, and understanding, and the higher rises our admiration of the endless wisdom which ordains and penetrates the whole creation.[17][18][19]

Commemoration

[edit]

Werner von Siemens' portrait appeared on the 20 ℛ︁ℳ︁ banknote issued by the Reichsbank from 1929 until 1939.[20] Printing ceased in 1939 but the note remained in circulation until the issue of the Deutsche Mark on 21 June 1948.

In 1923, German botanist Ignatz Urban published Siemensia, which is a monotypic genus of flowering plant from Cuba belonging to the family Rubiaceae and was named in honor of Werner von Siemens.[21]
