Who is Judith Yagudah from Children of the Flames: Dr. Josef Mengele and the Untold Story of the Twins of Auschwitz and what is their importance?

Judith Yagudah was sent to the twins' barracks with her twin sister, Ruthie, and her mother. Judith's sister lost several toes to frostbite, a consequence of an experiment by Mengele. Ruthie was frail toward the end of the war and died as the camp was liberated. Judith and her mother returned home and eventually relocated to Israel.
