The official founding date of the German motor vehicle manufacturer BMW is 7 March 1916, when an aircraft engine manufacturer called "Bayerische Flugzeugwerke AG" was formed. This company was renamed to "Bayerische Motoren Werke" (BMW) in 1922. However the name BMW dates back to 1913, when the original company used the name BMW (which in German appears as "Rapp Motorenwerke"). BMW's first product was a straight-six aircraft engine called the BMW IIIa. Following the end of World War I, BMW remained in business by producing motorcycle engines, farm equipment, household items and railway brakes. The company produced its first motorcycle, the "BMW R 32" in 1923.
