Prince Albert of Thurn und Taxis, Germany
Albert von Thurn und Taxis first appeared on Forbes's billionaire list as an 8-year-old, the 12th prince in his family line in Germany of Thurn und Taxis. One of the most well-rounded men in royalty, he has two degrees in theology and economics. He is also a race car driver in his spare time. While he is related to every royal family in Europe, if you think snagging him will make you a queen then you're out of luck. German royal titles were abolished in 1919, but his estimated net worth? $2.2 billion.
