Rudolf Vrba

Rudolf Vrba was a Slovak-Jewish biochemist who, as a teenager in 1942, was deported to the Auschwitz concentration camp in German-occupied Poland. He escaped from the camp in April 1944, at the height of the Holocaust, and co-wrote the Vrba-Wetzler report, a detailed report about the mass murder taking place there. The report, distributed by George Mantello in Switzerland, is credited with having halted the mass deportation of Hungary's Jews to Auschwitz in July 1944, saving more than 200,000 lives. After the war, Vrba trained as a biochemist, working mostly in England and Canada.
