BMW
After the end of World War I in 1918, BMW was forced to cease aircraft engine production by the terms of the Versailles Armistice Treaty. To remain in business, BMW produced farm equipment, household items and railway brakes. In 1922, former major shareholder Camillo Castiglioni purchased the rights to the name BMW, which led to the company descended from Rapp Motorenwerke being renamed Süddeutsche Bremse AG (known today as Knorr-Bremse). Castiglioni was also an investor in another aircraft company, called "Bayerische Flugzeugwerke", which he renamed BMW.The disused factory of Bayerische Flugzeugwerke was re-opened to produce engines for buses, trucks, farm equipment and pumps, under the brand name BMW. BMW's corporate history considers the founding date of Bayerische Flugzeugwerke (7 March 1916) to be the birth of the company.
Automotive industry in Germany
Germany was always inspired by the British automotive industry in the late 1860s and as motor-car pioneers Karl Benz (who later went on to start Mercedes-Benz) and Nikolaus Otto developed four-stroke internal combustion engines in the late 1870s, with Benz fitting his design to a coach in 1887, which led to the modern day motor car. By 1901, Germany was producing about 900 cars a year. In 1926, Daimler-Benz was formed from the predecessor companies of Karl Benz and Gottlieb Daimler and produced cars under the marque of Mercedes-Benz. In 1916 BMW was founded, but didn't start auto production until 1928.
