Tema Sznajderman was a fearless operative in the Jewish resistance to Nazism. She assumed undercover identities to investigate and transfer vital information across borderlines.

Kashariyot were young women who traveled on illegal missions for the Jewish resistance in German-occupied Eastern Europe during the Holocaust. They smuggled goods, news, and other Jews in and out of the ghettos of Poland, Lithuania, and parts of Russia. While those who fought the Germans within the ghettos are often most celebrated for their heroism, kashariyot were essential in the survival of Jews within ghettos.
