Bayerische Motoren Werke AG (English: Bavarian Motor Works) is an independent German automobile manufacturer.
Beginning with aircraft engines, BMW AG produced a variety of products in its early years, eventually shifting to motorcycle production in 1923 and automobiles in 1929. The circular blue and white BMW logo, which has not been altered throughout the company's history, does not in fact symbolize a spinning propeller according to a BMW spokesman Joerg Huebner (although the imagery did appear in post-WWI advertisements). The BMW roundel badge is believed to have been partially derived from the logo of its predecessor company Rapp Motorenwerke, while ultimately taking on the colors and checkers from the arms of Bavaria (fusilly in bend argent and azure). Significant aircraft power plants of pre-WWII and WWII included the BMW 132 and BMW 801 air-cooled radial engines, and the pioneering BMW 003 axial-flow turbojet. BMW's factories were damaged badly in the war, and many surviving machine tools were confiscated by the victorious Allies.
