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.
BMW
BMW acquired the Hans Glas company based in Dingolfing, Germany, in 1966. Glas vehicles were briefly badged as BMW until the company was fully absorbed. It was reputed that the acquisition was mainly to gain access to Glas’ development of the timing belt with an overhead camshaft in automotive applications, although some saw Glas’ Dingolfing plant as another incentive. However, this factory was outmoded and BMW's biggest immediate gain was, according to themselves, a stock of highly qualified engineers and other personnel. The Glas factories continued to build a limited number of their existing models, while adding the manufacture of BMW front and rear axles until they could be closer incorporated into BMW.
