Siemens is a multinational engineering and electronics company based in Germany. It is one of the largest engineering companies in the world with operations in more than 190 countries and a workforce of more than 350,000 people. With a focus on the fields of electrification, automation, and digitalisation, Siemens has made a name for itself as a leader in innovative technology solutions.

Siemens was founded in 1847 by Werner von Siemens and Johann Georg Halske. The company has grown significantly since then and today is divided into three businesses: Smart Infrastructure, Digital Industries and Mobility. Each division focuses on different areas of technology and innovation, such as energy efficiency, mobility, digitalization, and sustainability initiatives.

Siemens is known for its cutting-edge products and services. These include products like the world’s first industrial robot and the world’s most advanced medical imaging systems. The company is also involved in research and development efforts to advance technology in the areas of renewable energy, energy storage, and smart grid technology.

In addition to its technological innovations, Siemens is also committed to sustainability and corporate social responsibility. The company has implemented a number of initiatives to reduce its environmental footprint and promote social responsibility. Siemens also works with various nonprofit organizations to promote education, health, and economic development around the world.


Siemens & Halske, founded by Werner von Siemens and Johann Georg Halske in 1847, made pioneering contributions to telegraphic cables and electrical equipment. Their use of gutta-percha for cable insulation proved crucial for electric-light cables, and they were instrumental in laying telegraph lines and the first successful deep-sea telegraphic cable. Expanding globally, they established branches in London and St Petersburg, ventured into electrical lighting, and received significant contracts, including building a telegraph line between London and Calcutta and laying the first transatlantic cable. Siemens & Halske also patented an improved telephone version and powered the world's first electric street lighting in the UK, impacting AC network experimentation in the United States. Werner Siemens' achievements were recognised with ennoblement by the German kaiser in 1888.

Siemens & Halske went public in 1897 and created a subsidiary focused on electric power engineering in 1903. Siemens & Halske collaborated on medical equipment development and contributing to World War II's V 2 rocket manufacturing.

The company continued to expand globally, establishing its American subsidiary, Siemens Inc., in New York in 1954. It ventured into the field of computers and produced its first mainframe in 1955. 

Over the years, Siemens Ltd., a flagship listed company of Siemens AG in India, emerged, with Siemens AG Germany holding 75% of its capital. Siemens went on to construct a nuclear power station in Argentina in 1968, becoming the first such facility in South America. In 1969, Siemens formed Kraftwerk Union with AEG, pooling their nuclear power businesses. In 1972, it became the official supplier of telecommunications and data processing equipment for the Munich Olympic Games.

The company entered a joint venture with Advanced Micro Devices (AMD) in 1977, aiming to enhance its technology expertise and enter the American market. In 1978, Fortune magazine recognised Siemens as the primary competition for GE, surpassing Westinghouse. However, diverging visions for Advanced Micro Computers led to AMD buying out Siemens' stake in the American division in 1979.

Siemens expanded through acquisitions, including the UK defense and technology company Plessey in 1988 and the solar photovoltaic business from ARCO Solar in 1989. In the early 1990s, Siemens undertook various projects, including setting up a plant in India for the manufacture of switchgear and acquiring the Industrial Systems Division of Texas Instruments in the US. In 1992, Dr. Heinrich von Pierer took the helm of Siemens, leading the company into a new era of technological developments, including collaborations with IBM and Toshiba to develop high-power microprocessors. By 1994, Siemens became Germany's third-largest public corporation and a leading manufacturer of electrical products and power generation systems.

In 1997, Siemens Financial Services (SFS) was founded to manage financing and financial risks within the company. However, not all divisions thrived; the rail systems division faced losses, while the industry division, led by Edward Krubasik, saw a 60 percent profit increase.

During the early 2000s, Siemens experienced a mixed financial performance, with increasing sales but declining net income in 2001 due to higher costs and a significant increase in contract orders in the Transportation group. The company underwent restructuring and divested from low-performing companies. Siemens expanded into various markets, including telecommunications and handsets, while acquiring new divisions like wind energy company Bonus Energy. Siemens also made several strategic acquisitions and divestments to reshape its business portfolio, including the sale of IT Solutions and Services subsidiary and its stake in Framatome. In response to the Fukushima disaster, Siemens decided to exit the nuclear sector.

In January 2020, Siemens agreed to acquire 99% of C&S Electric, an Indian switchgear manufacturer, for €267 million. The takeover received approval from the Competition Commission of India in August 2020. In April 2020, Siemens Energy was established as an independent company from the energy division of Siemens.
