Walter Caro worked as a commercial clerk at the same firm as his younger brother Werner. When their company was “Aryanized” in 1939, the German Labor Front demanded the brothers’ dismissal. After that, they had to perform forced labor.
Up until Operation Factory on February 27, 1943, Walter Caro lived with his brother Kurt and the latter’s non-Jewish wife Frida in Berlin-Prenzlauer Berg; he then went into hiding. A short time later, he went to his trusted doctor Georg Groscurth’s clinic and offered to forge Wehrmacht papers and other documents, for the doctor to pass on to people living underground. When the European Union resistance group, of which Dr. Groscurth was a member, was broken up in September 1943, the Gestapo also put Walter Caro on their wanted list. His brother Kurt was arrested, and survived his interrogations without revealing where Walter was hiding. Despite this, Walter Caro was apprehended in September 1943 and deported on April 18, 1944. He died in Auschwitz in March 1945, two months after the camp was liberated.
