1901 to 1933

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.

, 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. The company supplied electrical parts to

. 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. 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. 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

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 military contractor. The payments included $450 million in fines and penalties and a forfeiture of $350 million in profits in the US. Siemens also revamped its compliance systems, appointing Peter Y.

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. 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 bribes paid to Japanese naval authorities. 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-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. 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
