The only residents of Wilhelmstraße 77 were Hitler and his bodyguards, adjutants, orderlies and servants. It is unknown if the "Vorbunker" was used before January 1945. Hitler transferred his headquarters to the "Führerbunker" in Berlin on 16 January 1945, where he (along with his influential private secretary, "Reichsleiter" Martin Bormann and others), remained until the end of April. Thereafter, the "Vorbunker" was used by various military officers and housed men from Hitler's personal bodyguard. In April 1945, as the Battle in Berlin raged on, Joseph Goebbels showed his strong support for Hitler by moving his family into the "Vorbunker". He occupied a room in the "Führerbunker" which had recently been vacated by Hitler's personal physician, Theodor Morell. Two rooms in the "Vorbunker" were used for food supply. Constanze Manziarly, Hitler's personal cook/dietitian, made meals in the kitchen, which was equipped with a refrigerator and a wine store.
