siemens.
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
telegraph 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.
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 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
1966 –
Siemens AG was later led by his brothers, his three sons
Arnold,
Wilhelm and
Carl Friedrich and his nephews
Hermann,
Ernst 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. He built the world's first electric
elevator in 1880. His company produced the tubes with which
Wilhelm Conrad Roentgen investigated x-rays. He claimed invention of the
dynamo although others invented it earlier. 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. 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.
