How Did Gert Westphal Die?

Curt Gerhard Westphal, stage name Gert Westphal, was a German actor, one of the best-known audiobook narrators and speakers in German, described as "König der Vorleser" and "der Caruso der Vorleser". After his reading of her husband's works, Katia Mann called him "des Dichters oberster Mund". The literary critic Marcel Reich-Ranicki said he was probably the best reciter of German.
