Georg Friedrich Prinz von Preussen

Georg Friedrich, Prince of Prussia (born 10 June 1976, as ''Georg Friedrich Ferdinand Prinz von Preußen'') is a German heir who is the current head of the Prussian branch of the House of Hohenzollern, the former ruling dynasty of the German Empire and of the Kingdom of Prussia. He is the great-great-grandson of Wilhelm II, the last German Emperor and King of Prussia, who abdicated and went into exile upon Germany's defeat in World War I in 1918.

He is known to the German public mostly due to his claims against the German State to return former possessions to his family. Provided by Wikipedia
