In July 1942, the Zentralstelle für jüdische Auswanderung (Central Office for Jewish Emigration) ordered Margot Frank to come to be taken to a work camp. Otto Frank told his family that they would hide in rooms above and behind the place where his company worked on the Prinsengracht. The Prinsengracht was a street next to one of Amsterdam's canals, where some of his most trusted employees would help them. The notice to Margot made them move a few weeks earlier than they had expected.
