Gustav von Wangenheim's son claimed his father, after being arrested by the NKVD and a lengthy interrogation, signed a statement that implicated Carola Neher as being "anti soviet" but had in fact explicitly refuted the accusation that Neher and her husband Anatol Becker had planned to murder Stalin.

After World War II, he returned to East Germany, where he worked for the DEFA as screenwriter and director.

The couple had two sons, Friedel and Edi, and twin daughters, Elisabeth and Eleonora von Wangenheim.
