Vitka Kempner (Hebrew: ויטקה קובנר; 14 March 1920, Kalisz – 14 February 2012)[1] was a Polish Jewish partisan leader during World War II.
She served in the Fareynikte Partizaner Organizatsye (FPO) and, alongside Rozka Korczak and founder Abba Kovner, assumed a leadership role in its successor group, the Nakam.
When Lithuania fell to the Germans eight months later, Kempner and tens of thousands of other Jews were forced into a ghetto, where she met Korczak and Kovner.
Kempner played an integral leading role in the organization, and is famous for blowing up a Nazi train line with a homemade bomb.
Kempner is remembered in the song Shtil, di nakht iz oysgeshternt by Hirsh Glick, which celebrates her heroic attack on a German convoy in the Vilnius sector in 1942.
