The hiding place
The Movable Bookcase
Behind this (movable) bookcase is the entrance to the Secret Annex (Photo: Maria Austria, 1954).
The hiding place is located in an empty section of the building owned by Otto Frank's company. While business continues, as usual, in the front part of the building, there are people hiding in the annex out back.
A bookcase conceals the door
Before too long, the entrance to the Secret Annex is concealed behind a movable bookcase. Father Voskuijl, the warehouse manager, constructs the movable bookcase to conceal the entrance to the Secret Annex.
“Now our Secret Annex has truly become secret…Mr. Kugler thought it would be better to have a bookcase built in front of the entrance to our hiding place. It swings out on its hinges and opens like a door. Mr. Voskuijl did the carpentry work. (Mr. Voskuijl has been told that the seven of us are in hiding, and he's been most helpful.),”
Anne writes this in her diary on August 21, 1942, when there there are still only seven people in hiding. Fritz Pfeffer joins the group at a later date, on November 16, 1942.
