For more than two years Anne Frank and her family lived in the annex of the building at Prinsengracht 263 where Anne’s father, Otto Frank, also had his business. The Van Pels family and Fritz Pfeffer hid there with them. The doorway to the annex was concealed behind a moveable bookcase constructed especially for this purpose. The office personnel knew of the hiding place and helped the eight people by supplying them with food and news of the outside world. On August 4, 1944, the hiding place was betrayed. The people in hiding were deported to various concentration camps. Only Otto Frank survived the war.
