In 1941 Berek Jakubowicz (now Benjamin Jacobs) was deported from his Polish village and remained a prisoner of the Reich until the final days of the war. His possession of a few dental tools and rudimentary skills saved his life. Jacobs helped assemble V1 and V2 rockets in Buchenwald and Dora-Mittelbau, spent a year and a half in Auschwitz, where he was forced to remove gold teeth from corpses, and survived the RAF attack on three ocean liners turned prison camps in the Bay of Lubeck. This is his story.
