Victor Kugler, Johannes Kleiman, Miep Gies, and Bep Voskuijl were the only employees who knew of the people in hiding. Along with Gies' husband Jan Gies and Voskuijl's father Johannes Hendrik Voskuijl, they were the "helpers" for the duration of their confinement. The only connection between the outside world and the occupants of the house, they kept the occupants informed of war news and political developments.

Frank wrote of their dedication and of their efforts to boost morale within the household during the most dangerous of times. All were aware that, if caught, they could face the death penalty for sheltering Jews.
