[[Siemens & Halske]] was founded by [[Werner von Siemens]] and [[Johann Georg Halske]] on 1 October 1847. Based on the [[telegraph]], their 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 12 October.<ref>{{cite web |url=https://new.siemens.com/global/en/company/about/history/news/the-year-is-1847.html |title=The year is 1847 – How it all began", Siemens Historical Institute |publisher=Siemens AG |access-date=27 October 2019 |archive-date=11 December 2020 |archive-url=https://web.archive.org/web/20201211154421/https://new.siemens.com/global/en/company/about/history/news/the-year-is-1847.html |url-status=dead }}</ref>

In 1848, the company built the first long-distance telegraph line in Europe: 500&nbsp;km from Berlin to [[Frankfurt am Main]]. In 1850, the founder's younger brother, Carl Wilhelm Siemens, later [[Carl Wilhelm Siemens|Sir William Siemens]], started to represent the company in London. The [[Siemens Brothers|London agency]] became a branch office in 1858. 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 telegraph]] line stretching over 11,000&nbsp;km from [[London]] to [[Kolkata|Calcutta]].<ref>{{cite web |url=https://new.siemens.com/global/en/company/about/history/news.html |title=Halfway around the world in 28 minutes – Indo-European Telegraph Line |website=Siemens Historical Institute |archive-url=https://web.archive.org/web/20080120233553/http://w4.siemens.de/archiv/en/laender/asien/indien.html |archive-date=20 January 2008|url-status=dead |access-date=12 January 2008}}</ref>

A similar system was also independently invented by [[Ányos Jedlik]] and [[Charles Wheatstone]], but Siemens became the first company to build such devices. In 1881, a Siemens [[Alternating current|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 locomotive|electric trains]] and [[light bulbs]]. In 1885, Siemens sold one of its generators to [[George Westinghouse]], thereby enabling Westinghouse to begin experimenting with AC networks in Pittsburgh, Pennsylvania.

In 1887, Siemens opened its first office in Japan.<ref>Siemens website [http://www.siemens.com/history/en/news/1125_japan.htm 1 August 2012 – 125 Years Siemens in Japan (1887–2012)] {{webarchive |url=https://web.archive.org/web/20160305014307/http://www.siemens.com/history/en/news/1125_japan.htm |date=5 March 2016 }} Retrieved on 12 August 2013</ref> In 1890, the founder retired and left the running of the company to his brother Carl and sons Arnold and Wilhelm. In 1892, Siemens was contracted to construct the [[Hobart, Tasmania|Hobart]] [[Trams in Hobart|electric tramway]] in [[Tasmania]], [[Australia]], as it increased its markets. The system opened in 1893 and became the first complete electric tram network in the Southern Hemisphere.<ref>{{cite web |title=A Brief History of the Hobart Electric Trams |url=http://www.hobartcity.com.au/tramway/history.htm |archive-url=https://web.archive.org/web/20031224052130/http://www.hobartcity.com.au/tramway/history.htm |url-status=dead |archive-date=24 December 2003 |publisher=Hobart City Council |access-date=13 June 2021}}</ref>

Siemens & Halske (S & H) was incorporated in 1897 and then merged parts of its activities with Schuckert & Co., Nuremberg, in 1903 to become [[Siemens-Schuckert]].  In 1907, Siemens ([[Siemens & Halske]] and [[Siemens-Schuckert]]) had 34,324 employees and was the seventh-largest company in the German empire by number of employees.<ref>{{Cite journal |last=Fiedler |first=Martin |year=1999 |title=Die 100 größten Unternehmen in Deutschland – nach der Zahl ihrer Beschäftigten – 1907, 1938, 1973 und 1995 |journal=Zeitschrift für Unternehmensgeschichte |publisher=Verlag C.H.

In 1932, [[:de:Reiniger, Gebbert & Schall|Reiniger, Gebbert & Schall]] (Erlangen), Phönix AG (Rudolstadt) and Siemens-Reiniger-Veifa mbH (Berlin) merged to form the [[Siemens-Reiniger-Werke AG]] (SRW), the third of the so-called parent companies that merged in 1966 to form the present-day Siemens AG.<ref name="historysite">{{cite web |url=https://new.siemens.com/global/en/company/about/history/news/setting-the-course-of-the-future.html |title=Setting the Course for the Future – The Founding of Siemens AG |access-date=5 June 2019 |archive-date=25 October 2020 |archive-url=https://web.archive.org/web/20201025080305/https://new.siemens.com/global/en/company/about/history/news/setting-the-course-of-the-future.html |url-status=dead }}</ref>

In the 1920s, Siemens constructed the [[Shannon hydroelectric scheme|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 underpaid workers, only to be overruled by the [[Cumann na nGaedheal]] government.<ref>{{cite news |url=http://findarticles.com/p/articles/mi_qn4161/is_20020804/ai_n12846719 |title=Ardnacrusha – Dam hard job |date=4 August 2002 |work=[[Sunday Mirror]] |access-date=18 September 2010 |first=Andrew |last=Bushe |url-status=dead |archive-url=https://web.archive.org/web/20080221060803/http://findarticles.com/p/articles/mi_qn4161/is_20020804/ai_n12846719 |archive-date=21 February 2008}}</ref>

Siemens exploited the forced labour of women deported to the [[Ravensbrück concentration camp]]; a Siemens factory was located in front of the camp.<ref>[https://histoire-image.org/fr/etudes/travail-force Forced labor at Siemens Ravensbrück]</ref>

During the final years of [[World War II]], numerous plants and factories in Berlin and other major cities were destroyed by Allied air raids. To prevent further losses, manufacturing was therefore moved to alternative places and regions not affected by the air war. The goal was to secure continued production of important war-related and everyday goods. According to records, Siemens was operating almost 400 alternative or relocated manufacturing plants at the end of 1944 and in early 1945.

In 1972, Siemens sued German satirist F.C. Delius for his satirical history of the company, ''Unsere Siemens-Welt'', and it was determined much of the book contained false claims although the trial itself publicized Siemens's history in Nazi Germany.<ref>[http://www.adl.org/braun/dim_13_2_forgetting_print.asp German Industry and the Third Reich: Fifty Years of Forgetting and Remembering] {{webarchive |url=https://web.archive.org/web/20121030133244/http://www.adl.org/braun/dim_13_2_forgetting_print.asp |date=30 October 2012 }}.

=== 2005 and continuing: worldwide bribery scandal ===
Beginning in 2005, Siemens became embroiled in a multi-national [[bribery]] scandal.<ref>{{Cite news |date=20 May 2007 |title=Bloomberg.com |url=https://www.bloomberg.com/apps/news?pid=20601100&sid=agxq4nZkE.lc |access-date=12 January 2008}}</ref> Among the various incidents was the [[Siemens Greek bribery scandal]], where the company was accused of deals with Greek government officials during the [[2004 Summer Olympics]]. This case, along with others, triggered legal investigations in Germany, initiated by prosecutors in Italy, Liechtenstein, and Switzerland, and later followed by an American investigation in 2006 due to the company's activities while listed on US stock exchanges.<ref name="NYThow">{{cite news |last1=Schubert |first1=Siri |last2=Miller |first2=T. Christian |date=20 December 2008 |title=At Siemens, Bribery Was Just a Line Item |work=The New York Times |url=https://www.nytimes.com/2008/12/21/business/worldbusiness/21siemens.html?mcubz=2}}</ref>

Investigations found that Siemens had a pattern of bribing officials to secure contracts, with the company spending approximately $1.3 billion on bribes across several countries, and maintaining separate accounting records to conceal this. Following the investigations, Siemens settled in December 2008, paying a combined total of approximately $1.6 billion to the US and Germany in what was, at the time, the largest bribery fine in history.<ref name="NYThow" /> In addition, the company was required to invest $1 billion in developing and maintaining new internal compliance procedures. Siemens admitted to violating the accounting provisions of the [[Foreign Corrupt Practices Act]], while its Bangladesh and Venezuela subsidiaries pleaded guilty to paying bribes.<ref name="WaPo20082">{{cite news |last1=O'Reilly |first1=Cary |last2=Matussek |first2=Karin |date=16 December 2008 |title=Siemens to Pay $1.6 Billion to Settle Bribery Cases |newspaper=The Washington Post |url=https://www.washingtonpost.com/wp-dyn/content/article/2008/12/15/AR2008121502926.html}}</ref>

Despite initial expectations of a fine as high as $5 billion, the final amount was significantly less, in part due to Siemens's cooperation with the investigators, the upcoming change in the US administration, and Siemens's role as a US [[Arms industry|military contractor]].<ref name="Guardian20082">{{cite news |last1=Gow |first1=David |date=15 December 2008 |title=Record US fine ends Siemens bribery scandal |work=The Guardian |url=https://www.theguardian.com/business/2008/dec/16/regulation-siemens-scandal-bribery}}</ref> The payments included $450 million in fines and penalties and a forfeiture of $350 million in profits in the US. Siemens also revamped its [[Regulatory compliance|compliance]] systems, appointing [[Peter Y. Solmssen]], a US lawyer, as an independent director in charge of compliance and accepting oversight from [[Theo Waigel]], a former German finance minister. Siemens implemented new [[anti-corruption]] policies, including a comprehensive anti-corruption handbook, online tools for due diligence and compliance, a confidential communications channel for employees, and a corporate disciplinary committee. This process involved hiring approximately 500 full-time compliance personnel worldwide.<ref>{{cite web |date=2 May 2013 |title=United States of America v.

Siemens's bribery culture was not new; it was highlighted as far back as 1914 when both Siemens and Vickers were involved in a scandal over [[Siemens scandal|bribes paid to Japanese naval authorities]].<ref>{{cite book |last=Sims |first=Richard |title=Japanese Political History Since the Meiji Renovation 1868–2000 |publisher=Palgrave Macmillan |year=2001 |isbn=0-312-23915-7 |page=113}}</ref> The company resorted to bribery as it sought to expand its business in the developing world after World War II. Up until 1999, bribes were a [[Tax deduction|tax-deductible]] business expense in Germany, with no penalties for bribing foreign officials. However, with the implementation of the 1999 [[OECD Anti-Bribery Convention]], Siemens started using off-shore accounts to hide its bribery.

During the investigation, key player Reinhard Siekaczek, a mid-level executive in the telecommunications unit, provided critical evidence. He disclosed that he had managed an annual global bribery budget of $40 to $50 million and provided information about the company's 2,700 worldwide contractors, who were typically used to channel money to government officials. Notable instances of bribery included substantial payments in Argentina, Israel, Venezuela, China, Nigeria, and Russia to secure large contracts.<ref name="NYThow" />

The investigation resulted in multiple prosecutions and settlements with various governments, as well as legal action against Siemens employees and those who received bribes. Noteworthy cases include the conviction of two former executives in 2007 for bribing Italian energy company [[Enel]], a settlement with the Greek government in 2012 for 330 million euros over the Greek bribery scandal, and a guilty plea in 2014 from former Siemens executive Andres Truppel for channeling nearly $100 million in bribes to Argentine government officials.<ref name="timesofisrael.com2">{{cite web |title=Ex-power company execs charged in massive Siemens bribery case |url=http://www.timesofisrael.com/ex-power-company-execs-charged-in-massive-siemens-bribery-case/ |access-date=26 August 2016 |website=[[The Times of Israel]]}}</ref> Siemens also faced repercussions from the [[World Bank]] due to fraudulent practices by its Russian affiliate. In 2009, Siemens agreed not to bid on World Bank projects for two years and to establish a $100 million fund at the World Bank to support anti-corruption activities over 15 years, known as the "Siemens Integrity Initiative." Other substantial fines include a payment of ₦7 billion (US${{To USD|7000|NGA|year=2010}} million) to the [[Federal government of Nigeria|Nigerian government]] in 2010, and a US$42.7 million penalty in Israel in 2014 to avoid charges of securities fraud.
