Ruth Altbeker Cyprys was a Polish Jewish lawyer, one of the few women admitted to the bar in Warsaw before World War II. She was married and the pregnant when her husband was arrested by the Soviets in eastern Poland and sent to Siberia. She was forced into the Warsaw Ghetto by the invading Germans. In 1943, she and her two-year-old daughter Eva were deported by the Nazis to the Treblinka death camp. In her memoirs, Ruth explains how she used a small metal saw to cut through the metal bars of the train and jump out. She had bribed fellow passengers to throw Eva out into the snow after her. They returned to Warsaw, where Ruth assumed the identity of Marianna Lukaszewska, a non-Jewish teacher, and changed jobs and areas of employment frequently. She survived the war through luck and her wits and cunning, and recovered Eva from the Christian Polish family who had sheltered her. Her husband Jerzy (George) also survived and the family later settled in England. Her journal, written just after the war, was discovered by her two daughters 50 years later, after Ruth's death in 1979. It was published as A Jump for Life: A Survivor's Journal from Nazi-Occupied Poland, in 1997.
