Yetti Sterensis (nee Straucher) grew up in a traditional Jewish family. She had one brother.
From 1941 to 1942 she was forced to live in the Lwow Ghetto with her parents. However, her parents and brother were shot in an aktion and buried in a mass grave.
In the ghetto, she was helped by a German soldier to get false identification papers so that she could pass as a Christian. She signed up for labor and traveled five days to Greitz Turrenger in German. There she worked in a munitions factory with ten other Jewish girls where were also posting as gentiles.
Yetti was libered in 1945 by the American Army. After liberation, she married another survivor. The couple lived in a displaced persons camp in Germany from 1946 to 1948 when they emigrated to the United States.
