At Auschwitz, after the chambers were filled, the doors were shut and pellets of Zyklon-B were dropped into the chambers through vents, releasing toxic prussic acid, or hydrogen cyanide. Those inside died within 20 minutes; the speed of death depended on how close the inmate was standing to a gas vent, according to the commandant Rudolf Höss, who estimated that about one-third of the victims died immediately. Johann Kremer, an SS doctor who oversaw the gassings, testified that: "Shouting and screaming of the victims could be heard through the opening and it was clear that they fought for their lives." The gas was then pumped out, the bodies were removed, gold fillings in their teeth were extracted, and women's hair was cut. The work was done by the Sonderkommando, work groups of mostly Jewish prisoners. At Auschwitz, the bodies were at first buried in deep pits and covered with lime, but between September and November 1942, on the orders of Himmler, they were dug up and burned. In early 1943, new gas chambers and crematoria were built to accommodate the numbers.
Mengele joined the Nazi Party in 1937. He received his medical degree in 1938, the same year he joined the SS. Mengele was drafted into the army in June 1940, and subsequently volunteered for the medical service of the Waffen-SS (Armed SS). There is little (and often contradictory) documentation about Mengele's activities between this time and early 1943. It is clear, however, that he first functioned as a medical expert for the Race and Settlement Main Office in summer 1940 at the Central Immigration Office North-East in Posen (today Poznan). He then served as a medical officer with the SS Division “Wiking” (SS Pioneer Battalion V), with which he saw action on the Eastern Front.
According to the copyright laws in the European Union, as a general rule, rights of authors end seventy years after their death. Hence, the copyright of the diary expired on 1 January 2016. In the Netherlands, for the original publication of 1947 (containing parts of both versions of Anne Frank's writing), as well as a version published in 1986 (containing both versions completely), copyright initially would have expired not 50 years after the death of Anne Frank (1996), but 50 years after publication, as a result of a provision specific for posthumously published works (1997 and 2036, respectively).
Not long after beginning the survey of the site, Freund and his team confirmed the existence of a previously unmarked burial pit. At 80 feet across and 15 feet deep, the scientists calculated that the grave contained the cremated remains of as many as 7,000 people. The researchers also released the preliminary results of their search for the tunnel, along with a series of ERT-generated cross sections that revealed the tunnel’s depth beneath the ground’s surface (15 feet at points) and its dimensions: three feet by three feet at the very widest, not much larger than a human torso. From the entrance inside the bunker to the spot in the forest, now long grown over, where the prisoners emerged measured more than 110 feet. At last, there was definitive proof of a story known until now only in obscure testimonies made by a handful of survivors—a kind of scientific witness that transformed “history into reality,” in the words of Miri Regev, Israel’s minister of culture, who highlighted the importance of documenting physical evidence of Nazi atrocities as a bulwark against “the lies of the Holocaust deniers.”
The Germans invaded the Soviet Union in 1941. Leaders of the SS and police and leaders of the German armed forces had concluded pre-invasion agreements. In accordance with these agreements, SS and police units—including Einsatzgruppen of the German Security Police and SD and battalions of the German Order Police—followed German troops into newly occupied Soviet territory. Acting as mobile killing units, they conducted shooting operations aimed at annihilating entire Jewish communities. By autumn 1941, the SS and police introduced mobile gas vans. These paneled trucks had exhaust pipes reconfigured to pump poisonous carbon monoxide gas into sealed spaces, killing those locked within. They were designed to complement ongoing shooting operations.
Although Yad Vashem (Israel’s Memorial to the Six Million) has honored over 1,200 Righteous Among the Nations since 1953, it is impossible to generalize about the motives, deeds, and actual numbers of these rescuers. Some rescuers acted within the planned context of guerrilla units and resistance movements, others used the buildings and funds of the Roman Catholic church to aid Jews.
In 1942, Auschwitz II (Birkenau), originally intended to house slave laborers, began to be used instead as a combined labor camp and extermination camp. Prisoners were transported there by rail from all over German-occupied Europe, arriving in daily convoys. By July 1942, SS doctors were conducting "selections" where incoming Jews were segregated, and those considered able to work were admitted into the camp while those deemed unfit for labor were immediately killed in the gas chambers. The arrivals that were selected to die, about three-quarters of the total,[a] included almost all children, women with small children, pregnant women, all the elderly, and all of those who appeared (in a brief and superficial inspection by an SS doctor) to be not completely fit and healthy.
