Manziarly began working as cook and dietitian for Hitler from his 1943 stays at the Berghof until his death in Berlin on 30 April 1945. Hitler took up residence in the "Führerbunker" on 16 January 1945. The Reich Chancellery bunker complex in Berlin was made up of two bunkers, the lower "Führerbunker" and the older upper bunker, known as the "Vorbunker". Two rooms in the "Vorbunker" were used for food supply. Another room was made up of the kitchen which had a refrigerator and a wine store. Manziarly used the kitchen to prepare Hitler's meals while he stayed in the "Führerbunker".
