Lucy (Luzie) Mann was born in Bad Kissingen on May 21, 1907 as the fourth of the six children of the butcher Lazarus Mann and his wife Cilly, née Löwenberger. The family lived in Weingasse where Lucy’s father ran a butchery.

In February 1927, she moved to Berlin and worked as a nurse in the Jewish Hospital there.

Lucy Mann was deported from Berlin to Ravensbrück and murdered in the killing station of Bernburg an der Saale on May 8, 1942. Her brother Max also became a victim of the Shoa according to the report of his brother Kurt. He was imprisoned in the Mauthausen concentration camp and committed suicide there in August 1942. Obviously, he could no longer endure the agony and terror and ran into the camp's electric fence. Lucy’s mother and the other siblings, however, succeeded in emigrating to the United States in time and survived.
