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.
History of BMW
After the war, BMW survived by making pots, pans, and bicycles until 1948, when it restarted motorcycle production. Meanwhile, BMW's factory in Eisenach fell in the Soviet occupation zone and the Soviets restarted production of pre-war BMW motorcycles and automobiles there. This continued until 1955, after which they concentrated on cars based on pre-war DKW designs. BMW began building cars in Bavaria in 1952 with the BMW 501 luxury saloon. Sales of their luxury saloons were too small to be profitable, so BMW supplemented this with building Isettas under licence. Slow sales of luxury cars and small profit margins from microcars caused the BMW board to consider selling the operation to Daimler-Benz. However, Herbert Quandt was convinced to purchase a controlling interest in BMW and to invest in its future.
