Both Anne and Margot kept diaries while they were in hiding, although Margot’s diaries were never found. Living in hiding meant the group also lived in constant fear of being discovered—they were unable to go outside, had to be quiet, conceal any lights used after sunset, and keep the curtains and windows closed during the day. They lived in extremely close quarters with each other and were completely dependent on Miep Gies, Johannes Kleiman, Victor Kugler, and Bep Voskuijl, Otto’s employees, for food, supplies, and moral support. The group in hiding got news from the radio and from these helpers, who also brought books and gifts. Anne wrote, "They come upstairs every day and talk to the men about business and politics, to the women about food and wartime difficulties and to the children about books and newspapers. They put on their most cheerful expressions, bring flowers and gifts for birthdays and holidays and are always ready to do what they can."
The property is of adequate size to ensure the complete representation of the features and processes that convey its significance. Potential threats to the integrity of the property include the difficulty in preserving the memory of the events and their significance to humanity. In the physical sphere, significant potential threats include natural decay of the former camps’ fabric; environmental factors, including the risk of flooding and rising groundwater level; changes in the surroundings of the former camps; and intensive visitor traffic.
The release took almost twelve hours, during which we had to stand in line waiting in the open air, without food. Part of the release ceremonies was the address of an S.S. man. He called our attention to the fact that we were forbidden to tell anything that we had seen in the camp. Although we all had to fill in a form of this nature, I cannot recognize an obligation in this respect, not only because it was forced, but also because it was imposed by a party that habitually does not keep its promises.
Some Auschwitz prisoners were subjected to inhumane medical experimentation. The chief perpetrator of this barbaric research was Josef Mengele (1911-79), a German physician who began working at Auschwitz in 1943. Mengele, who came to be known as the “Angel of Death,” performed a range of experiments on detainees. For example, in an effort to study eye color, he injected serum into the eyeballs of dozens of children, causing them excruciating pain. He also injected chloroform into the hearts of twins, to determine if both siblings would die at the same time and in the same manner.
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.
