More than 500 Berlin Jews were bound to forced labor at the factory of the metal and electrical company Ehrich and Graetz in Berlin Treptow between autumn 1940 and February 1943. At the "Final Roundup" on 27 February 1943, the last remaining Jewish forced laborers were seized, interned, and then for the most part deported.

Towards the end of the war, two employees saved the passport photographs of the over 500 forced laborers in their company which are now on display in the permanent exhibition at the Jewish Museum Berlin.

Aside from complete documentation of this unique material, the new volume describes the forced laborers' conditions of work and daily life, the story of the company under the National Socialist regime, and narrates the lives and fates of men and women in ten individual biographies.
