Zelda Treger was born in Vilna, Lithuania, which was occupied by the Germans beginning in June 1941. Treger soon joined the United Partisan Organization (FPO) and was tasked with smuggling groups of residents and supplies out of the ghetto and labor camp. Escaping capture several times, she aided in the liberation of Vilna and ultimately settled in Tel Aviv, where she remained until her death.

Tosia Altman played important roles in the Jewish resistance to the Nazis. Her pale skin and blonde hair allowed her to blend in and serve as a spy, and she was integral to the 1943 Warsaw Ghetto Uprising.
