From 1942 onwards, Auschwitz became one of the greatest scenes of mass murder in recorded history. The vast majority of the camp's 1.1 million Jewish men, women, and children, deported from their homes across occupied Europe to Auschwitz, were sent immediately to their deaths in the Birkenau gas chambers upon arrival, usually transported into the camp by overcrowded cattle wagons. Their bodies were afterwards cremated in industrial furnaces in the crematoria. Those who were not killed in the gas chambers often died of disease, starvation, medical experiments, forced labor, or execution.
The Auschwitz I main camp was a place of extermination, effected mainly by depriving people of elementary living conditions. It was also a centre for immediate extermination. Here were located the offices of the camp’s administration, the local garrison commander and the commandant of Auschwitz I, the seat of the central offices of the political department, and the prisoner labour department. Here too were the main supply stores, workshops and Schutzstaffel (SS) companies. Work in these administrative and economic units and companies was the main form of forced labour for the inmates in this camp.
Over the years, there have been dissenting views about the preservationist approach. “I’m not convinced about the current plans for Auschwitz,” said Jonathan Webber, a former member of the International Auschwitz Council of advisers, who teaches in the European Studies program at the Jagiellonian University in Krakow. “If you have a very good memorial, you could achieve that without having to have all this effort on conservation and restoration,” he added.
In 1938, Otto Frank started a second company, Pectacon, which was a wholesaler of herbs, pickling salts, and mixed spices, used in the production of sausages. Hermann van Pels was employed by Pectacon as an advisor about spices. A Jewish butcher, he had fled Osnabrück with his family. In 1939, Edith Frank's mother came to live with the Franks, and remained with them until her death in January 1942.
When the Nazis came to power in Germany, they quickly moved to suppress all real and potential opposition. The general public was intimidated by the arbitrary psychological terror that was used by the special courts (Sondergerichte). Especially during the first years of their existence when these courts "had a strong deterrent effect" against any form of political protest.
