Siemens was founded by Werner von Siemens on 12 October, 1847. Based on the telegraph, his invention used a needle to point to the sequence of letters, instead of using Morse code. The company; then called Telegraphen-Bauanstalt von Siemens & Halske opened its first workshop on October 12.

In 1848, the company built the first long-distance telegraph line in Europe; 500 km from Berlin to Frankfurt am Main. In 1850 the founder's younger brother, Carl Wilhelm Siemens started to represent the company in London. In the 1850s, the company was involved in building long distance telegraph networks in Russia. In 1855, a company branch headed by another brother, Carl Heinrich von Siemens, opened in St Petersburg, Russia. In 1867, Siemens completed the monumental Indo-European (Calcutta to London) telegraph line.[5]

In 1881, a Siemens AC Alternator driven by a watermill was used to power the world's first electric street lighting in the town of Godalming, United Kingdom. The company continued to grow and diversified into electric trains and light bulbs. In 1890, the founder retired and left the company to his brother Carl and sons Arnold and Wilhelm. Siemens & Halske (S&H) was incorporated in 1897. In 1907 Siemens had 34,324 employees and was the seventh-largest company in the German empire by number of employees.[6] (see List of German companies by employees in 1907)

In 1919, S&H and two other companies jointly formed the Osram lightbulb company. A Japanese subsidiary was established in 1923.

During the 1920s and 1930s, S&H started to manufacture radios, television sets, and electron microscopes.

Ardnacrusha hydro power station

In the 1930s Siemens constructed the Ardnacrusha Hydro Power station on the River Shannon in the then Irish Free State, and it was a world first for its design. The company is remembered for its desire to raise the wages of its under-paid workers only to be overruled by the Cumann na nGaedhael government.[7]

World War II era

Preceding World War II Siemens was involved in funding the rise of the Nazi Party and the secret rearmament of Germany. During the Second World War, Siemens supported the Hitler regime, contributed to the war effort and participated in the "Nazification" of the economy. Siemens had many factories in and around notorious concentration camps [8][9] to build electric switches for military uses.[10] In one example, almost 100,000 men and women from Auschwitz worked in a Siemens factory inside the camp, supplying the electricity to the camp. The Siemens logo is still visible above the gas chambers at Buchenwald concentration camp[11].


In the 1950s and from their new base in Bavaria, S&H started to manufacture computers, semiconductor devices, washing machines, and pacemakers. Siemens AG was incorporated in 1966. The company's first digital telephone exchange was produced in 1980. In 1988 Siemens and GEC acquired the UK defense and technology company Plessey. Plessey's holdings were split, and Siemens took over the avionics, radar and traffic control businesses — as Siemens Plessey.

In 1991, Siemens acquired Nixdorf Computer AG and renamed it Siemens Nixdorf Informationssysteme AG.

In October 1991, Siemens acquired the Industrial Systems Division of Texas Instruments, Inc, based in Johnson City, Tennessee. This division was organized as Siemens Industrial Automation, Inc., and was later absorbed by Siemens Energy and Automation, Inc.

In 1997 Siemens introduced the first GSM cellular phone with colour display. Also in 1997 Siemens agreed to sell the defense arm of Siemens Plessey to British Aerospace (BAe) and a UK government agency, the Defence Analytical Services Agency (DASA). BAe and DASA acquired the British and German divisions of the operation respectively.[citation needed]

In 1999, Siemens' semiconductor operations were spun off into a new company known as Infineon Technologies. Also, Siemens Nixdorf Informationssysteme AG formed part of Fujitsu Siemens Computers AG in that year. The retail banking technology group became Wincor Nixdorf.

In February 2003, Siemens reopened its office in Kabul.[12]

In 2005 Siemens sold the Siemens mobile manufacturing business to BenQ, forming the BenQ-Siemens division.

In 2006, Siemens announced the purchase of Bayer Diagnostics, which was incorporated into the Medical Solutions Diagnostics division on 1 January 2007.

In March 2007 a Siemens board member was temporarily arrested and accused of illegally financing a business-friendly labour association which competes against the union IG Metall. He has been released on bail. Offices of the labour union and of Siemens have been searched. Siemens denies any wrongdoing.[13]

In April 2007, the Fixed Networks, Mobile Networks and Carrier Services divisions of Siemens merged with Nokia’s Network Business Group in a 50/50 joint venture, creating a fixed and mobile network company called Nokia Siemens Networks. Nokia delayed the merger[14] due to bribery investigations against Siemens.[15]

In October 2007, a court in Munich found that the company had bribed public officials in Libya, Russia, and Nigeria in return for the awarding of contracts; four former Nigerian Ministers of Communications were among those named as recipients of the payments. The company admitted to having paid the bribes and agreed to pay a fine of 201 million euros. In December 2007, the Nigerian government canceled a contract with Siemens due to the bribery findings.[16][17]

In July 2008, Siemens AG announced a joint venture of the Enterprise Communications business with the Gores Group. The Gores Group holding a majority interest of 51% stake, with Siemens AG holding a minority interest of 49%[18]

In April 2009, Fujitsu Siemens Computers became Fujitsu Technology Solutions as a result of Fujitsu buying out Siemens' share of the company.


Siemens was part of a joint venture with Nokia in 2008 to provide Iran's monopoly telecom company with technology that allowed it to intercept the internet communications of its citizens to an unprecedented degree.[19][20] The technology reportedly allowed it to use 'deep packet inspection' to read and even change the content of everything from "emails and internet phone calls to images and messages on social-networking sites such as Facebook and Twitter". The technology "enables authorities to not only block communication but to monitor it to gather information about individuals, as well as alter it for disinformation purposes" expert insiders told the Wall Street Journal. During the post-election protests in Iran in June 2009, Iran's internet access was reported to have slowed to less than a tenth of its normal speeds, and experts suspected this was due to the use of the interception technology.[21] The joint venture company, Nokia-Siemens Networks, asserted in a press release that it provided Iran only with a 'lawful intercept capability' "solely for monitoring of local voice calls". "Nokia Siemens Networks has not provided any deep packet inspection, web censorship or Internet filtering capability to Iran," it said.[22]

Chief executives and executive board members

Corporate affairs


Peter Löscher (formerly of Merck) is the current president and the CEO as of July 1, 2007.[23] He succeeded Dr. Klaus Kleinfeld after the scandal charges of bribery against Siemens. Gerhard Cromme is the current chairman of the supervisory board of Siemens AG. He succeeded Dr. Heinrich von Pierer on April 26, 2007.

2007 Price fixing fine

In January 2007 Siemens was fined €396 million by the European Commission for price fixing in EU electricity markets through a cartel involving 11 companies, among which ABB, Alstom, Fuji, Hitachi Japan, AE Power Systems, Mitsubishi Electric Corp, Schneider, Areva, Toshiba and VA Tech[24] According to the Commission, "between 1988 and 2004, the companies rigged bids for procurement contracts, fixed prices, allocated projects to each other, shared markets and exchanged commercially important and confidential information."[24] Siemens was given the highest fine of €396 million, more than half of the total, for its alleged leadership role in the incident.

Bribery case

Siemens agreed to pay a record $1.34 billion in fines in December 2008[25] after being investigated for serious bribery, involving Heinz-Joachim Neubürger, former chief financial officer, Karl-Hermann Baumann, another former CFO and exchairman, and Johannes Feldmayer, a former management board member.[26] The investigation found questionable payments of roughly €1.3 billion, from 2002 to 2006 that triggered a broad range of inquiries in Germany, the United States and many other countries.[27]

In May 2007 a German court convicted two former executives of paying about €6 million in bribes from 1999 to 2002 to help Siemens win natural gas turbine supply contracts with Enel, an Italian energy company. The contracts were valued at about €450 million. Siemens was fined €38 million.[28]
