Robert Bosch GmbH (; ), commonly known as Bosch (styled BOSCH), is a German multinational engineering and technology company headquartered in Gerlingen, Baden-Württemberg, Germany. It is 94 percent owned by the Robert Bosch Stiftung, a charitable institution. Although the charity is funded by owning the vast majority of shares, it has no voting rights and is involved in health and social causes unrelated to Bosch's business.
The company was founded by Robert Bosch in Stuttgart in 1886. In the late 1890s, Bosch started installing magneto ignition devices into vehicles; the automotive sector would be a key long term market for the firm. In 1901, Bosch opened its first factory in Stuttgart. In 1917, it was reorganised as a corporation. Prior to the First World War, the company generated 92 percent of its sales outside of Germany, however, Bosch lost most of its international holdings following the conflict. Using a combination of loans and a greater focus on business acumen at the board level, the firm quickly rebuilt its international presence during the interwar period, particularly in South America and Asia. Diversification efforts in the 1930s included the purchase of a gas appliances production facility, the development of an electric drill, electric refrigerator, and car radio.
Both prior and during the Second World War, the company had links to the ruling Nazi Party, using as many as 20,000 forced labourers in its production plants to produce ammunition and outfit Luftwaffe aircraft as part of the German war effort during the Second World War. At the end of WWII, all of Bosch's foreign assets were seized and most employees were laid off, however, the firm quickly recovered on the back of strong economic performance within West Germany. An economic downturn in 1966 motivated Bosch to adopt a strategy of decentralisation, diversification, and overseas expansion. The end of the Cold War led to the company expanding across the former Eastern Bloc, setting up new manufacturing facilities and subsidiaries across Eastern Europe.
Bosch's core operating areas are spread across four business sectors: mobility (hardware and software), consumer goods (including household appliances and power tools), industrial technology (including drive and control), and energy and building technology. By the 21st century, Bosch had become the largest automotive supplier in the world. Due to this, the company's fiscal performance has often been impacted by trends impacting the automotive sector. In 2025, Bosch experienced a substantial drop in profitability that was attributed to a decline in global German car sales.
History 1886–1920
The company began in Stuttgart-West as the (Workshop for Precision Mechanics and Electrical Engineering) on 15 November 1886. At the time of its founding, Stuttgart lacked municipal electricity, which hampered the business's early opportunities and pushed it near to bankruptcy before the local authority announced the decision to build a power station to serve the city in 1893. In 1897, Bosch started installing magneto ignition devices into automobiles, an early step towards becoming a key supplier of ignition systems over time. In 1902, the chief engineer at Bosch, Gottlob Honold, unveiled the high-voltage magneto ignition system with a spark plug.
In 1901, Bosch opened its first factory in Stuttgart. In 1906, the company produced its 100,000th magneto. In the same year, Bosch introduced the eight-hour day for workers. In 1910, the Feuerbach plant was founded near Stuttgart, where Bosch began producing generators and headlights (Bosch-Light) in 1914. The motorization of road traffic led to the company's rapid growth after 1900. Bosch had a workforce of 45 in 1901, which expanded to more than 1,000 employees by 1908.
Bosch's international development began in 1898 with the opening of a branch in London, followed the next year by outlets in Paris, Vienna, and Budapest. By 1909, Bosch was represented by trading partners on every continent. Bosch opened the first factory outside Germany in Paris in 1905 and the first on another continent in 1912 in Springfield, Massachusetts (USA). In 1913, Bosch founded an apprentice workshop to recruit young people for the production of automotive electrics. Prior to the First World War, the company generated 92 percent of its sales outside of Germany.
In 1913, the company was subject to industrial action over employees being laid off as a result of a reduction in orders received. As the labour dispute escalated, Robert Bosch terminated all agreements between the company and trade unions and joined the metal industry employers’ association. The dispute was only healed by the First World War. In 1917, Bosch was transformed into a corporation and remained so until 1937, when Robert Bosch regained sole ownership by purchasing back his shares. In the process, the company became a limited liability company (GmbH).
1921–1945 In the aftermath of the First World War, Bosch was compelled to forfeit the majority of its international holdings, including its US factories. Thus, the company opted to rebuild its global activities throughout much of the interwar period, which included expansion in both South America and Asia. In 1922, Illies & Company established a sales office for Bosch in Calcutta, India. In the years that followed, Bosch concluded contracts in Asia with sales partners in Malaysia, Singapore, Thailand, and Indonesia, as well as on the American continents with partners in Mexico, Peru, Colombia, and Ecuador.
In the 1920s, Bosch expanded its product range to include numerous automotive technology products essential for cars, such as electric horns (1921), windshield wipers (1926), and direction indicators ("trafficator", 1927). Robert Bosch personally led the project to develop a diesel injection pump, which went into production in late 1927. To fuel the company's expansion plans, loans were taken out and the company's management board was restructured around business interests over technical ones.
Growth proved to be somewhat unsteady, occasional sharp short-term downturns in demand would sometimes necessitate drastic cuts; between September 1925 and September 1926, roughly 5,600 associates, almost half of Bosch's employees, were laid off. The company was deeply impacted by the Great Depression, nessitating numerous lay offs, salary reductions, and the implementation of reduced working hours. Bosch pursued a strategy of diversification, which was achieved both through completing acquisitions and the launching of products into new markets.
Bosch purchased the gas appliances production facility from Junkers & Co. in 1932. In 1932, the company developed its first electric drill and presented its first car radio. In 1933, Bosch introduced its first electric refrigerator for private households.
Effect of Nazi regime Like most German businesses at the time, Bosch had links to the ruling Nazi Party. Prior to the Second World War, Bosch under the direction of the Nazi Party began relocating armament production to Germany's interior. Bosch founded two factories in 1935 and 1937: Dreilinden Maschinenbau GmbH in Kleinmachnow and Feinmechanische Industrie GmbH (later Trillke-Werke GmbH) in Hildesheim, for armament production. These factories were built secretly and in close cooperation with the Nazi authorities. In 1937, Bosch AG became a limited liability company (GmbH).
The Bosch subsidiary Dreilinden Maschinenbau GmbH (DLMG) in Kleinmachnow employed around 5,000 people, more than half of whom were forced labourers, prisoners of war, and female concentration camp prisoners, including many women from the Warsaw Uprising. During the Second World War, there were at least 3,000 workers in the mechanics division at the Bosch Hildesheim factory, almost all of them from nearby occupied countries; there were only 200 recorded German workers. In the last years of the conflict, all new German tanks included starter elements from the Bosch factory in Hildesheim; the company also had a monopoly position in the outfitting of Luftwaffe aircraft.
1946–1999
At the end of the conflict, the company was compelled to stop production, causing nearly all of its workforce to lose their jobs, while all foreign assets were seized and foreign markets remained closed to Bosch for years. It opted to enter new markets during the 1950s, including mobile hydraulics, medical electronics, and radio technology. Between the late 1940s and the mid 1960s, the firm benefitted from strong economic performance within West Germany. Following an economic downturn in 1966, management sought to avoid layoffs by adopting a strategy of decentralisation, diversification, and overseas expansion. The efforts included early work on research projects into emerging technologies, such as integrated circuits, electronically-controlled fuel injection, and anti-lock braking systems (ABS). This research led to a major milestone in 1978, when Bosch and Mercedes-Benz jointly introduced an electronically controlled anti-lock braking system, one of the first to reach series production, launching it in the Mercedes-Benz S-Class. In the 1980s, Bosch entered the telecommunications sector, producing technology for satellites and mobile phones. In the 1980s, Bosch entered the telecommunications sector, producing technology for satellites and mobile phones.
The company did not record a single operating loss throughout the Cold War era.The end of the Cold War and the fall of the Iron Curtain opened valuable opportunities to Bosch. By 1994, it had subsidiary companies across 13 countries of the former Eastern Bloc; the company also established manufacturing plants in the Czech Republic, Poland, Hungary, and the Russian Federation. In 1990, 49 percent of Bosch's sales were generated inside Germany, by 2000, 72 percent of sales came from outside Germany. Additionally, an early 1990s slump in the European automotive sector and an intense period of price-oriented competition against other suppliers negatively impacted Bosch. In response to lost orders, reduced working hours were enacted for 20,000 Germany-based associates, along with early retirement arrangements and termination agreements, which collectively involved around 13,000 employees.
21st century In 2001, Bosch acquired Mannesmann Rexroth AG, which they later renamed to Bosch Rexroth AG. In the same year, the company opened a new testing center in Vaitoudden, close to Arjeplog in north Sweden. A new development center for automotive engineering, in Abstatt, Germany was constructed shortly after. In 2002, Bosch acquired Philips CSI, which at the time was manufacturing a broad range of professional communication and security products and systems including CCTV, congress, and public address systems. In the 2000s the company developed the electric hydraulic brake, common rail fuel injection with piezo-injectors, digital car radio with a disc drive, and the cordless screwdriver with a lithium-ion battery in 2003. In 2004, Bosch bought Sigpack Systems from SIG.
Bosch received the () from the German president in 2005 and 2008. A new development center was planned in 2008 in Renningen. In 2014, the first departments moved to the new center, while the remaining departments followed in 2015. In 2006, Bosch acquired Telex Communications and Electro-Voice. In 2009, Bosch invested about in research and development. Approximately 3,900 patents are published per year. In addition to increasing energy efficiency by employing renewable energies, the company plans to invest in new areas such as biomedical engineering.
