Headquartered in Berlin and Munich, Siemens Group is one of the largest electrical engineering and electronics companies in the world.
German engineer and entrepreneur invented the motor, generator, tram and compass telegraph, improved the submarine cable, proposed the open hearth steelmaking method, and innovated the steelmaking process. He was the founder of Siemens.
Born in a farmer's family in Hanover, he ranks fourth among 14 children.
Because of his poor family, Siemens joined the army after finishing high school.
During its service, Siemens was very interested in telegraph technology and invented the compass telegraph, which was very popular in the19th century.
Later, Siemens was sentenced to five years in prison for dueling with others.
In prison, Siemens built a small electronic laboratory and conducted some electrical research.
1847, Siemens and John George Halske, a mechanical engineer, established the Siemens-Halske telegraph manufacturing company, which mainly produced the compass telegraph invented by Siemens, relying on the 6,842 taler silver coins invested by his cousin (1 taler is equivalent to 3 marks), which was the predecessor of Siemens later.
1848, Siemens won the contract for the telegraph line from Frankfurt to Berlin, and it has developed greatly since then.
When Siemens was founded, it not only relied on telegraph business, but also supported the development of its main business by developing and popularizing new technologies.
Besides managing the company, Siemens also spends more time on engineering research.
1866, Siemens put forward the working principle of the generator, and an engineer from Siemens completed the first human generator.
In the same year, Siemens also invented the first DC motor.
These technologies developed by Siemens are often put into the market immediately or applied to new products.
For example, trams (188 1), trolleybuses (1882), elevators (1880) and electric trains (1879) were all first put into the market by Siemens using the inventions of its founders.
Ironically, the electric car, which was not developed until the end of the 20th century, was first invented by Siemens in 1898.
1890 Siemens retired.
Previously, German Emperor Friedrich III awarded him the title of nobility.
Siemens' name is also used to name the unit of conductivity.
