Bronia (Bronka) Klibanski was one of the heroic Kashariyot (couriers) of the Jewish resistance during the Holocaust. She became the primary kasharit for the Dror Zionist group in 1943, obtaining critical weapons for the Bialystok ghetto revolt, gathering intelligence, rescuing other Jews, and saving the secret archive of the ghetto.

Liza Czapnik was a Polish freedom fighter during World War II who started working against the Nazi occupation after witnessing a mass murder of Jewish people near her hometown. After being interned in the Grodno ghetto, she escaped and began working as a courier for the anti-fascist underground in Bialystok. After the war, she earned a PhD and taught English until 1991, when she made Aliyah and settled in Beersheva.
