It was also at the Humboldt that she received her doctorate, in 1960, for a dissertation entitled "Protein Release from Rat Liver Mitochondria" ("Eiweißfreisetzung aus Rattenlebermitochondrien"), and later, in 1969, her habilitation (higher level qualification) for which she was supervised by Samuel Mitja Rapoport.
