The Richest Man in Central Europe
Camillo Castiglioni was not a mechanic; he was a shark. Born in Trieste, he became the most powerful financier in Austria-Hungary during World War I. He loved airplanes and owned the Hansa-Brandenburg aircraft company. When he needed more engines for his planes, he looked at the struggling Rapp Motorenwerke in Munich and saw potential where others saw failure.
Creating BMW
In 1917, Castiglioni bought the company, fired Karl Rapp, and renamed it Bayerische Motoren Werke (BMW). He installed Franz Josef Popp as the General Director and provided the massive capital needed to develop the high-altitude BMW IIIa engine. Without Castiglioni's wallet and his demand for aircraft engines, BMW would have likely dissolved into history as just another failed workshop.
The Magician's Fall
Castiglioni was known as "The Financial Magician" for his complex dealings. He actually took the BMW name and rights with him to another company (BFW) in 1922, essentially re-founding BMW a second time. While he eventually lost his fortune in the turbulent economy of the 1920s and faced scandals, his aggressive maneuvering in 1917 and 1922 is the sole reason the BMW brand exists today.
