Miriam Kuperhand was the daughter of a prosperous Polish Jewish furrier. She grew up in Siemiatycze, a small town near what became the Russian-German border in 1939. At age 16, during the Nazi Occupation of the country in World War II, she and her brother first hid in an underground bunker with the rest of the family, and later roamed the countryside of Poland, hiding and searching for food and shelter. Her future husband Saul Kuperhand, the son of a poor Jewish shoemaker, escaped from the Treblinka death camp, where his whole family was murdered. Both survived with the help of Polish Christians, and their own wits, courage, resourcefulness, luck, and a strong will to live. After the war, they emigrated to USA, settling in Brooklyn, New York and running a clothing business. Their joint memoir, Shadows of Treblinka, was published in 1998.
