History of Siemens

The history of Siemens dates back to 1847 in Germany, when company Siemens & Halske was founded by Werner von Siemens and Johann Georg Halske. Their company was created around their new invention, which used a needle to point to a sequence of letters rather than morse code in the telegraph, also building the first long-distance telegraph line in Europe at 500km between Berlin and Frankfurt.

Siemens Logo

It wasn’t long until Siemens & Halske expanded from its German origins to open a new branch office in London in 1850, overseen by the founder’s younger brother Sir William Siemens. Another of the Siemens brothers, Carl Heinrich von Siemens, opened a further branch of the company in St Petersburg in 1855.

In the remainder of the 1800s, Siemens & Halske achieved many things, including the Indo-European telegraph line between London and Calcutta; the creation of an AC alternator driven by a windmill to light the streets of Godalming, UK; and the production of electric trains and light bulbs.

At the 1800s came to a close, founder Werner von Siemens retired and the company was left to operate under brother Carl Heinrich von Siemens and his sons Arnold and Wilhelm.

In 1903, some of Siemens & Halske’s operations were merged with Schuckert & Co., resulting in the company becoming Siemens-Schuckert. The growth of the company had been huge over the previous decades, resulting in the new merged group having over 34,000 employees. In the early 1900s, Siemens expanded its output to include the manufacture of radios, televisions and electron microscopes.

During World War 2, Siemens exploited the labour of people in concentration camps, and owned a machine tool production plant at the Bobrek concentration camp near Auschwitz. Between 1940 and 1945, they used 80,000 forced labourers, at least 5000 of whom were known to come from concentration camps. In a 2015 press release, marking 70 year since the liberation of Auschwitz, Siemens said:

“The management and employees of the company today profoundly regret that Siemens employed people against their will at the time when the company was integrated into the war economy of the unjust National Socialist regime. Siemens has acknowledged its responsibility by contributing a total of more than €150 million to the Jewish Claims Conference (1962), the Siemens Humanitarian Relief Fund for Former Forced Laborers (HHZ) (1998-2000) and the German Industry Foundation Initiative "Remembrance, Responsibility and Future."

In the 1950s, Siemens again expanded their range of products, this time to include computers, semiconductor devices, washing machines and pacemakers. Siemens & Halske, Siemens-Schuckertwerke and Siemens-Reiniger-Werke merged in 1966 to form Siemens AG. In the 1980s and 1990s, Siemens made several key acquisitions, buying UK defence and technology company Plessey in 1988, Nixdorf Computer AG in 1991, ROLM in 1992, and Westinghouse Power Generation in 1998.

Siemens Today

Today, Siemens continues to manufacture, develop and create products, solutions and services for a huge range of sectors and specialities, constantly increasing their range. Siemens is currently overseen by President and CEO Joe Kaeser, who has worked for the Siemens group since 1980.
