A lawyer from Cracow, Leon Feiner was a Bund activist, acting as the party's representative in the Cracow Municipal Council, before the War. In Warsaw, being a senior member fo the coordination committee he represented the Jewish underground in Zegota. It was Feiner who accompanied Jan Karski on his tour of the Ghetto, in October 1942. He was among the delegates of the Jewish Resistance to the A.K. (Interior Army) and left the Ghetto. Because he looked like a Polish aristocrat, Feiner was able to move about in Warsaw. Following the destruction of the Ghetto, he took the head of the underground Bund. Feiner died of cancer in February 1945, just after the Liberation of Poland.
