Siemens-Schuckert Werke, part of the Siemens electrical group, produced airships, aircraft and engines through World War I. After the war, the firm focused on aircraft engines.
In 1936, the factory at Spandau was reorganized as Brandenburgische Motorenwerke GmbH and known as Bramo.

The German Air Ministry merged Bramo into BMW in 1939.
