I was with my older sister Serena and we were sent to be forced labourers together in the Birkenau section of Auschwitz. Many times we were threatened with separation but somehow we managed to stay together. Later on, to our great relief we ran into my mother’s two younger sisters, our aunts Rose and Piri, who were in their early 20s. It was like finding our parents. They were such a huge moral and emotional support for us.
A typical concentration camp consisted of barracks that were secured from escape by barbed wire, watchtowers and guards. The inmates usually lived in overcrowded barracks and slept in bunk ”beds”. In the forced labour camps, for instance, the inmates usually worked 12 hours a day with hard physical work, clothed in rags, eating too little and always living under the risk of corporal punishment.
Auschwitz became a significant source of slave labor locally and functioned as an international clearing house. Of 2.5 million people who were deported to Auschwitz, 405,000 were given prisoner status and serial numbers. Of these, approximately 50 percent were Jews and 50 percent were Poles and other nationalities. Of those who received numbers, 65,000 survived. It is estimated that about 200,000 people passed through the Auschwitz camps and survived.

The main camp population grew from 18,000 in December 1942 to 30,000 in March 1943. In July or August 1941, Himmler briefed Höss about the 'Final Solution'. On September 3th, 1941, Soviet POWs at the Auschwitz main camp were used in trials of the poison gas Zyklon-B. This poison gas was produced by the German company "Degesch" (Deutsche Gesellschaft zur Schädlingsbekämpfung). The were gassed in underground cells in Block 11. After this trial, a gas chamber was rigged-up just outside the main camp and in February 1942, two temporary gas chambers opened at Birkenau. The crematories were built by the German company "Topf & son" located at Erfurt.

In the decades since its liberation, Auschwitz has become a primary symbol of the Holocaust. Historian Timothy D. Snyder attributes this to the camp's high death toll and "unusual combination of an industrial camp complex and a killing facility", which left behind far more witnesses than single-purpose killing facilities such as Chełmno or Treblinka.[272] In 2005 the United Nations General Assembly designated 27 January, the date of the camp's liberation, as International Holocaust Remembrance Day.[273] Helmut Schmidt visited the site in November 1977, the first West German chancellor to do so, followed by his successor, Helmut Kohl, in November 1989.[274] In a written statement on the fiftieth anniversary of the liberation, Kohl described Auschwitz as the "darkest and most horrific chapter of German history".[275]

On 26 June 1933, Himmler appointed Theodor Eicke commandant of Dachau, who in 1934 was also appointed the first Inspector of Concentration Camps (CCI). In addition, the remaining SA-run camps were taken over by the SS.[14][15][16] Dachau served as both a prototype and a model for the other Nazi concentration camps. Almost every community in Germany had members who were taken there. The newspapers continuously reported on "the removal of the enemies of the Reich to concentration camps" making the general population more aware of their presence. There were jingles warning as early as 1935: "Dear God, make me dumb, that I may not come to Dachau."[17]
