Prince Georg Friedrich and his then fiancée Princess Sophie of Isenburg at an anniversary celebration of 950 years Hohenzollern
Prince Wilhelm of Prussia (1906–1940) and wife Dorothea von Salviati (10 September 1907 – 7 May 1972). He renounced any rights to the succession for himself and his future children by marrying Dorothea, who was just a member from a small noble family. He served in the war and died in 1940. Hitler resented that the public showed a lot of affection towards the eldest son of the former Crown Prince. After the death of the Prince, Hitler forbid all men from royal houses to serve in the Wehrmacht.
