Notes

Since the family was German, it is likely that Pierre is not his original name. An unsourced (as at 18/12/2016) article on Wikipedia says that he changed his name from Hans to Pierre.

His mother was married to Max Gassmann whose death announcement in 1915 lists his children as Klaus-Ferdinand and Hans-Wolfgang; "Pierre" must be one of these. An article about Pierre Gassmann includes a photograph of Klaus and Pierre Gassmann in 1921, which means that "Pierre" must be Hans-Wolfgang.
