The Majdanek camp served from time to time as a killing site for Jews residing in the Generalgouvernement. In its gas chambers, the SS killed tens of thousands of Jews, primarily forced laborers too weak to work. The SS and police killed at least 152,000 people, mostly Jews, but also a few thousand Roma (Gypsies), in gas vans at the Chelmno killing center about thirty miles northwest of Lodz. In the spring of 1942, Himmler designated Auschwitz II (Auschwitz-Birkenau) as a killing facility. SS authorities murdered approximately one million Jews from various European countries at Auschwitz-Birkenau.
Anne Frank’s final diary entry, written on August 1, 1944, ends introspectively—a meditation on a struggle for moral transcendence set down in a mood of wistful gloom. It speaks of “turning my heart inside out, the bad part on the outside and the good part on the inside,” and of “trying to find a way to become what I’d like to be and what I could be if . . . if only there were no other people in the world.” Those curiously self-subduing ellipses are the diarist’s own; they are more than merely a literary effect—they signify a child’s muffled bleat against confinement, the last whimper of a prisoner in a cage. Her circumscribed world had a population of eleven—the three Dutch protectors who came and went, supplying the necessities of life, and the eight in hiding: the van Daans, their son Peter, Albert Dussel, and the four Franks. Five months earlier, on May 26, 1944, she had railed against the stress of living invisibly—a tension never relieved, she asserted, “not once in the two years we’ve been here. How much longer will this increasingly oppressive, unbearable weight press down on us?” And, several paragraphs on, “What will we do if we’re ever . . . no, I mustn’t write that down. But the question won’t let itself be pushed to the back of my mind today; on the contrary, all the fear I’ve ever felt is looming before me in all its horror. . . . I’ve asked myself again and again whether it wouldn’t have been better if we hadn’t gone into hiding, if we were dead now and didn’t have to go through this misery. . . . Let something happen soon. . . . Nothing can be more crushing than this anxiety. Let the end come, however cruel.” And on April 11, 1944; “We are Jews in chains.”

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).
Before the war, Mengele had received doctorates in anthropology and medicine, and began a career as a researcher. He joined the Nazi Party in 1937 and the SS in 1938. He was assigned as a battalion medical officer at the start of World War II, then transferred to the Nazi concentration camps service in early 1943 and assigned to Auschwitz, where he saw the opportunity to conduct genetic research on human subjects. His subsequent experiments focused primarily on twins, with little regard for the health or safety of the victims.[2][3]
