Auschwitz II-Birkenau was designated by Heinrich Himmler, Germany's Minister of the Interior, as the locus of the "final solution of the Jewish question in Europe." From spring 1942 until the fall of 1944, transport trains delivered Jews to the camp's gas chambers from all over Nazi-occupied Europe. The camp's first commandant, Rudolf HÃ¶ss, testified after the war at the Nuremberg Trials that up to three million people had died there, a figure since revised to 1.1 million, around 90 percent of them Jews. Others deported to Auschwitz included 150,000 Poles, 23,000 Roma and Sinti, 15,000 Soviet prisoners of war, and tens of thousands of people of diverse nationalities. Those not killed in the gas chambers died of starvation, forced labor, lack of disease control, individual executions, and medical experiments.
