On 17 September 1931, Hitler was with Hoffmann on a trip from Munich to Hamburg when the Fǖhrer got word that his niece, Geli Raubal – whom he adored and who accompanied him to almost all social events – had committed suicide by shooting herself. In his post-war memoir, "Hitler Was My Friend", Hoffmann expressed the opinion that Raubal killed herself because she was in love with someone other than Hitler, and could not take Hitler's rabidly jealous control of her life, especially after he found out that she had had an affair with Emil Maurice, Hitler's old comrade and chauffeur.
