Karl Rapp founded Rapp Motorenwerke GmbH in 1912 to produce aircraft. The company became Bayerische Motoren Werke (Bavarian Motor Works) in 1922. A year later, they created their first motorcycle. The initial car was manufactured in 1928. Since then, BMW has evolved into an international brand for luxury vehicles. BMW is headquartered in Munich and is the city’s largest employer with 35,500 people. Adjacent to their office building and factory is the BMW Welt. This futuristic showroom exhibits all current BMW models plus Rolls-Royces and Minis. The BMW Welt attracts about three million visitors a year.
