Donnevert studied medicine at the University of Göttingen and submitted his doctoral thesis in 1922. A dentist by profession Donnevert held a number of party administration posts in the early 1930s whilst also sering as a member of the Schutzstaffel, reaching the rank of Oberführer.
Donnevert worked in the office of the Deputy Führer until in 1940 when he was sent by Rudolf Hess and Martin Bormann to serve as deputy Gauleiter in the Sudetenland with specific instructions to control his new superior Konrad Henlein. Henlein was aware of Donnevert's intrigues against him and was able to engineer his deputy's removal from office. Donnevert remained on the pay-roll of the SS after this, albeit with little of real purpose to do, and he retreated into alcoholism.
