Her father died there on June 7, 1942. A few months later, her mother was deported during the Gehsperre action of September 5-12 1942. This deportation action resulted in the transport of over 15,000 Jews, mostly children under the age of 10, the elderly, and the infirm to their death in the Chelmno killing center. Hela was a gifted artist and she continued to create art in the ghetto. She died, age 19, of tuberculosis, on May 11, 1943. Her older brother, Szmul, died on July 19, 1943.
