The end of this collaboration had been coming for a long time. When Rapp’s departure was finally a certainty, another important decision had to be made. If the man who had lent his name to the company was now leaving it, a new name was naturally required. So, on 21 July 1917, Rapp Motorenwerke GmbH was renamed Bayerische Motorenwerke GmbH. It was thus the first company to bear this name and to use the abbreviation “BMW”. BMW AG acknowledges this date to be the official beginning of the company we know today.
