About Leon Feiner
Lived 1885 – 1945 (aged 59–60). Leon Feiner was a Polish lawyer.
Leon Feiner (nom-de-guerre "Mikołaj" (Michael), "Berezowski"; 1885 – February 22, 1945) was a Polish lawyer and activist. He was an activist of the General Jewish Labour Bund in Poland and between November 1944 and January 1945 the director (prezes) and vice-chairman of the Council to Aid Jews "Żegota".
Biography Feiner was born in 1885 in Kraków. He served as a defense attorney in political trials and was active in the Association of Socialist Lawyers. In 1939, he was sent to the Bereza Kartuska Prison for six weeks. After the outbreak of World War II with the German invasion of Poland, the Soviet Union also invaded on September 17, as part of the Molotov–Ribbentrop Pact between Nazi Germany and Soviet Union. Feiner was caught in the Soviet part of occupied Poland, was arrested by the NKVD and spent several months in a Soviet prison in Lida, near Wilno. Despite the fact that before the war on several occasions he had defended Polish Communists in court as an attorney, and that he had belonged to a socialist organization (the General Jewish Labour Bund in Poland), the Soviets authorities charged him with being a "fascist" and a "counter revolutionary"
Feiner also served as a guide for the Polish courier Jan Karski inside the Warsaw Ghetto (they both crossed into the ghetto through the Warsaw sewers). Karski asked Feiner what prominent American and British Jews should do. "Tell the Jewish leaders," Feiner said, "that ... they must find the strength and courage to make sacrifices no other statesmen have ever had to make, sacrifices as painful as the fate of my dying people, and as unique." Karski also took Feiner's report to the Polish-Jewish political leaders Szmul Zygielbojm and Ignacy Schwarzbart, who were serving on the Polish National Council of the Polish Government-in-Exile in London. The report described the deportation and murder of Jews in Poland, including a detailed report on Chełmno extermination camp, and gave the estimated number dead, as of May 1942, at 700,000 (the actual number was already much higher). Feiner's instructions to Zygielbojm were to cease mere protests and organize retaliatory bombing, leafleting and execution of Germans captured by the Allies, in response to the Nazi Holocaust. The description of the condition of Jews in German-occupied Poland and Feiner's instructions threw Zygielbojm into depression since he knew that the Allies would be unwilling to help
After the Warsaw Ghetto Uprising and the liquidation of the ghetto by the Germans, Feiner tried desperately to help those who were sent to slave labor camps. he died in Lublin soon afterward, on February 22. Even while in the hospital he maintained relationships with his friends and fellow political activists and participated in discussions of the future of the Bund in Poland.
He is buried in the main row of the Okopowa Street Jewish Cemetery in Warsaw (quarter 12).
