During the Second World War, a total of 2,711 people who had been deported to Germany from the occupied countries had to work at the Bosch plant in Hildesheim. In 1944, 4,290 men and women worked in the Trillke factory, 2,019 of whom were forced laborers, prisoners of war and military internees. In Hildesheim, a secret plant for the entire electrical equipment of tanks, tractors, and trucks of the Wehrmacht was built. They had to produce accessories for German Luftwaffe aircraft. The Bosch subsidiary Dreilinden Maschinenbau GmbH (DLMG) in Kleinmachnow employed around 5,000 people, more than half of whom were forced laborers, prisoners of war, and female concentration camp prisoners, including many women from the Warsaw Uprising. In 1937, Bosch AG became a limited liability company ( GmbH). These "shadow factories" were built under great secrecy and in close cooperation with the Nazi authorities. Both plants were used exclusively for armaments production. Bosch founded two such alternative plants in 19: Dreilinden Maschinenbau GmbH in Kleinmachnow near Berlin and Elektro- und Feinmechanische Industrie GmbH (later Trillke-Werke GmbH) in Hildesheim. In late 1933 negotiations between Robert Bosch AG and the Nazi Party began on relocating parts of armaments production to Germany's interior. In 1932 it bought Junkers & Co's gas appliances production and developed its first power drill and first car radio. In 1910, the Feuerbach plant was built near Stuttgart, where Bosch started to produce headlights in 1913.īosch started to produce windshield wipers in 1926 and diesel injection pumps in 1927. In 1901 Bosch opened its first factory, in Stuttgart and introduced the 8-hour day for workers.


In 1902, the chief engineer at Bosch, Gottlob Honold, unveiled the high-voltage magneto ignition system with spark plug. The next year Bosch presented a low voltage magneto for gas engines.įrom 1897, Bosch started installing magneto ignition devices into automobiles and became a supplier of an ignition system. The company started in a backyard in Stuttgart-West as the Werkstätte für Feinmechanik und Elektrotechnik ( Workshop for Precision Mechanics and Electrical Engineering) on 15 November 1886.
