Who founded Siemens?
Siemens was founded on October 1, 1847, by Werner von Siemens and Johann Georg Halske in Berlin, Germany. Werner von Siemens was a Prussian military officer and inventor who pioneered electrical engineering and built the company into one of Germany's largest industrial enterprises.

What is Siemens Healthineers?
Siemens Healthineers AG is a medical technology company that is majority-owned (approximately 75%) by Siemens AG but separately listed on the Frankfurt Stock Exchange. It provides medical imaging systems (MRI, CT, X-ray), laboratory diagnostics, and advanced therapy equipment. Siemens Healthineers is one of the world's largest medical technology companies with approximately €22.3 billion in FY2024 revenue.

Siemens was founded on October 1, 1847, by Werner von Siemens and Johann Georg Halske in Berlin, Germany. Werner von Siemens, a Prussian military officer and inventor, had developed an improved telegraph system and partnered with Halske, a precision mechanic, to commercialize it. The company's first major project was building a telegraph line from Berlin to Frankfurt in 1848, establishing Siemens as a pioneer in electrical communications infrastructure.

Throughout the second half of the 19th century, Siemens expanded rapidly across Europe and internationally, building telegraph networks across Russia, the Middle East, and India. The company developed the first electric streetcar in 1881 in Berlin and built some of the world's first electric power stations. Werner von Siemens also invented the dynamo-electric machine in 1866, a foundational contribution to electrical engineering.

By the early 20th century, Siemens had become one of Germany's largest industrial companies, operating in power generation, telecommunications, lighting, and transportation. The company merged with Schuckertwerke, an electrical manufacturer, in 1903 to form Siemens & Halske and Siemens-Schuckertwerke, which were later consolidated into Siemens AG in 1966.

During World War II, Siemens operated under the Nazi regime and used forced labor from concentration camps in its factories. The company has acknowledged this history and established a historical foundation to document and research this period. After the war, Siemens relocated its headquarters from Berlin to Munich and rebuilt its operations in West Germany.

Throughout the Cold War era, Siemens expanded globally, establishing manufacturing and sales operations across Europe, the Americas, and Asia. The company diversified into computers, semiconductors, and telecommunications equipment in the 1970s and 1980s, though it later divested many of these businesses as it refocused on its core industrial strengths.

In the 1990s and 2000s, Siemens underwent significant portfolio restructuring. The company spun off its semiconductor business as Infineon Technologies in 1999 and its mobile phone business as BenQ Mobile in 2005. Siemens acquired Dade Behring, Diagnostic Products Corporation, and other medical technology companies to build what became Siemens Healthineers.

In 2020, Siemens spun off its energy business as Siemens Energy AG, a separately listed company in which Siemens retained a minority stake. The spin-off reflected a strategic decision to focus the core Siemens business on industrial automation, smart infrastructure, and mobility rather than energy generation and transmission.

Roland Busch became President and CEO in February 2021, succeeding Joe Kaeser. Busch has accelerated the company's focus on industrial software and AI, including the announced acquisition of Altair Engineering, a simulation and AI software company, for approximately $10 billion, which was pending regulatory approval as of early 2025.

Siemens has established comprehensive sustainability and ethical practices focused on environmental responsibility, social commitment, and governance in the industrial technology sector. The company recognizes its role in addressing climate change, promoting diversity, and maintaining ethical business practices across its global operations.

Environmental sustainability initiatives include Science Based Targets validated by the Science Based Targets initiative for 2030 and 2050, aligning with the Paris Agreement goals. Siemens has committed to achieving carbon neutrality by 2030 across its operations, with significant investments in renewable energy and energy efficiency improvements. The company's DEGREE framework defines bold sustainability targets for 2030, covering decarbonization, resource efficiency, and people centricity.

Circular economy and resource efficiency programs include sustainable manufacturing processes, waste reduction initiatives, and product lifecycle management. Siemens has implemented circular economy principles in product design and manufacturing, focusing on material efficiency, recycling, and extended product lifecycles. The company's sustainable manufacturing initiatives target waste reduction, energy efficiency improvements, and environmentally responsible sourcing across its supply chain.

Social responsibility and diversity initiatives include comprehensive Gender Equity Programs ensuring equal opportunities regardless of gender, with focus on pay parity and career development. Siemens has achieved nearly 80% inclusion levels and increased average annual learning hours to 36.6 hours per employee. The company maintains Human Rights Policies based on international standards including the United Nations Guiding Principles on Business and Human Rights, with training programs conducted across global operations.

Siemens has received extensive recognition for innovation in industrial technology, sustainability leadership, and corporate achievement in the global industrial sector.

Siemens paid approximately $1.6 billion in fines in 2008 to settle bribery charges brought by U.S. and German authorities. The settlement resolved allegations that Siemens had systematically paid bribes to government officials in multiple countries to win public contracts over a period of years. The settlement was one of the largest bribery settlements in history at the time and prompted a significant overhaul of Siemens' compliance and ethics programs.

The company has also faced scrutiny over its historical use of forced labor during World War II. Siemens established the Siemens Historical Institute to research and document this period and has contributed to compensation funds for surviving victims.
