In the spring of 1945, Harald Quandt, a 23-year-old officer in the German Luftwaffe, was being held as a prisoner of war by Allied forces in the Libyan port city of Benghazi when he received a farewell letter from his mother, Magda Goebbels -- the wife of Nazi propaganda minister Joseph Goebbels.
The hand-written note confirmed the devastating news he had heard weeks earlier: His mother had committed suicide with her husband on May 1, after slipping their six children cyanide capsules in Adolf Hitler’s underground bunker in Berlin.
Quandt was released from captivity in 1947. Seven years later, he and his half-brother Herbert -- Harald was the only remaining child from Magda Goebbels’ first marriage -- would inherit the industrial empire built by their father, Guenther Quandt, which had produced Mauser firearms and anti-aircraft missiles for the Third Reich’s war machine. Among their most valuable assets at the time was a stake in car manufacturer Daimler AG. (DAI) They bought a part of Bayerische Motoren Werke AG (BMW) a few years later.

While the half-brothers passed away decades ago, their legacy has endured. Herbert’s widow, Johanna Quandt, 86, and their children Susanne Klatten and Stefan Quandt, have remained in the public eye as BMW’s dominant shareholders. The billionaire daughters of Harald Quandt -- Katarina Geller-Herr, 61, Gabriele Quandt, 60, Anette-Angelika May-Thies, 58, and 50-year-old Colleen-Bettina Rosenblat-Mo -- have kept a lower profile.
The four sisters inherited about 1.5 billion deutsche marks ($760 million) after the death of their mother, Inge, in 1978, according to the family’s sanctioned biography, “Die Quandts.” They manage their wealth through the Harald Quandt Holding GmbH, a Bad Homburg, Germany-based family investment company and trust named after their father. Fritz Becker, the chief executive officer of the family entities, said the siblings realized average annual returns above 7 percent from its founding in 1981 through 1996. Since then, the returns have averaged 7.6 percent.
