Prince Max Emanuel of Thurn and Taxis (b. 1935): Max Emanuel Prinz von Thurn und Taxis (born 7 September 1935) is the heir presumptive to the nominal "Fürst von Thurn und Taxis" title held, according to the traditional house law of the former German princely House of Thurn and Taxis, by his nephew Albert, 12th Prince of Thurn and Taxis.  Max Emanuel is a member of the former German princely House of Thurn and Taxis, whose wealth derives from founding the German postal service and brewing.  These preparations were defeated however, after locals and a conservation society managed to get a local referendum held in 1997 to scrap the plans.  Max Emanuel continued his plans four years later to build a hotel and golf course on the same site.  People living nearby were upset that the view seen from the castle's grounds would be ruined by new construction meant for tourists; consequently the local council ruled that most of the land surrounding the castle was unusable for commercial development.  Max Emanuel responded to these complaints by saying a luxury hotel would draw wealthy visitors to the village and help the local economy; restaurant, shop owners, and other members of the tourist industry tended to favor his plans, while village counselors, local farmers and others were opposed, believing that any commercial development would ruin the rural landscape and create too much noise.  Those in favor of King Ludwig's legacy stated that the hotel would violate the romantic legacy the mad king left.

Thurn and Taxis line of succession: The House of Thurn and Taxis, a princely dynasty which was sovereign until mediatized in 1806 and its noble status de-recognized following the fall of the German Empire in 1918, exists through several extant lines descending from Alexander Ferdinand, 3rd Prince of Thurn and Taxis.  The rule of succession is agnatic primogeniture, which only allowed males to succeed to the main princely title so long as male members of the family survive.
