An ardent Nazi, In 1943 Josef Mengele was appointed by Heinrich Himmler to be chief doctor at Birkenau, the supplementary extermination camp at Auschwitz, where he and his staff selected incoming Jews for labor or extermination and where he supervised medical experiments on inmates to discover means of increasing fertility (to increase the German “race”).
Responding to domestic pressures to act on behalf of Jewish refugees, U.S. Pres. Franklin D. Roosevelt convened, but did not attend, the Évian Conference on resettlement, in Évian-les-Bains, France, in July 1938. In his invitation to government leaders, Roosevelt specified that they would not have to change laws or spend government funds; only philanthropic funds would be used for resettlement. Britain was assured that Palestine would not be on the agenda. The result was that little was attempted and less accomplished.
^ Jump up to: a b Dan Stone (Histories of the Holocaust, 2010): "Europe's Romany (Gypsy) population was also the victim of genocide under the Nazis. Many other population groups, notably Poles, Ukrainians, and Soviet prisoners of war were killed in huge numbers, and smaller groups such as Jehovah's Witnesses, Black Germans, and homosexuals suffered terribly under Nazi rule. The evidence suggests that the Slav nations of Europe were also destined, had Germany won the war, to become victims of systematic mass murder; and even the terrible brutality of the occupation in eastern Europe, especially in Poland, can be understood as genocidal according to the definition put forward by Raphael Lemkin in his major study, Axis Rule in Occupied Europe (1944), the book that introduced the term 'genocide' to our vocabulary. Part of the reason for today's understanding, though, is a correct assessment of the fact that for the Nazis the Jews were regarded in a kind of 'metaphysical' way; they were not just considered as racially inferior (like Romanies), deviants (like homosexuals) or enemy nationals standing in the way of German colonial expression (like Slavs). ... [T]he Jews were to some extent outside of the racial scheme as defined by racial philosophers and anthropologists. They were not mere Untermenschen (sub-humans) ... but were regarded as a Gegenrasse: "a 'counter-race', that is to say, not really human at all. ... 'Holocaust', then, refers to the genocide of the Jews, which by no means excludes an understanding that other groups—notably Romanies and Slavs—were victims of genocide. Indeed ... the murder of the Jews, although a project in its own right, cannot be properly historically situated without understanding the 'Nazi empire' with its grandiose demographic plans."[32]
Whereas Christopher Browning places the Nazi plan to exterminate the Jews in the context of the Wehrmacht victories on the Eastern front, Cesarani argues that the German subsequent realisation that there would be no swift victory over the Soviet Union "scuppered the last territorial 'solution' still on the table: expulsion to Siberia".[119] Germany's declaration of war on the United States on December 11, 1941, "meant that holding European Jews hostage to deter the US from entering the conflict was now pointless. As Joseph Goebbels put it when he summarised a secret speech Hitler made on 12 December 1941: 'The world war is here, the destruction of the Jews must be the inevitable consequence'."[119][120] Cesarani concludes, the Holocaust "was rooted in anti-Semitism, but it was shaped by war".[119] The fact that the Nazis were, ultimately, so successful in killing between five and six million Jews was not due to the efficiency of the Third Reich or the clarity of their policies. "Rather, the catastrophic rate of killing was due to German persistence … and the duration of the murderous campaigns. This last factor was largely a consequence of allied military failure."[121]
There are three versions of the diary. The first is the diary as Anne originally wrote it from June 1942 to August 1944. Anne hoped to publish a book based on her entries, especially after a Dutch official announced in 1944 that he planned to collect eyewitness accounts of the German occupation. She then began editing her work, leaving out certain passages. That became the second version. Her father created a third version with his own edits as he sought to get the diary published after the war.
Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000.[323] In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans,[324] although the partisan movements did not always welcome them.[325] An estimated 20,000 to 30,000 joined the Soviet partisan movement.[326] One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers.[324] Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[327][r]

General Patch's 12th Armored Division, forging their way towards the Austrian border, uncovered horrors at a German prison camp at Schwabmunchen, southwest of Munich. Over 4,000 slave laborers, all Jews of various nationalities, were housed in the prison. The internees were burned alive by guards who set fire to the crude huts in which the prisoners slept, shooting any who tried to escape. Sprawled here in the prison enclosure are the burnt bodies of some of the Jewish slave laborers uncovered by the US 7th Army at Schwabmunchen, May 1, 1945. #
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).
At Auschwitz alone, more than 2 million people were murdered in a process resembling a large-scale industrial operation. A large population of Jewish and non-Jewish inmates worked in the labor camp there; though only Jews were gassed, thousands of others died of starvation or disease. During the summer of 1944, even as the events of D-Day (June 6, 1944) and a Soviet offensive the same month spelled the beginning of the end for Germany in the war, a large proportion of Hungary’s Jewish population was deported to Auschwitz, and as many as 12,000 Jews were killed every day.
The diary is not written in the classic forms of "Dear Diary" or as letters to oneself; Anne calls her diary "Kitty", so almost all of the letters are written to Kitty. Anne used the above-mentioned names for her annex-mates in the first volume, from September 25, 1942 until November 13, 1942, when the first notebook ends.[18] It is believed that these names were taken from characters found in a series of popular Dutch books written by Cissy van Marxveldt.[18]
Mengele's work also involved carrying out selections, a task that he chose to perform even when he was not assigned to do so, in the hope of finding subjects for his experiments,[33] with a particular interest in locating sets of twins.[34] In contrast to most of the other SS doctors, who viewed selections as one of their most stressful and unpleasant duties, he undertook the task with a flamboyant air, often smiling or whistling a tune.[35][31] He was also one of the SS doctors responsible for supervising the administration of Zyklon B, the cyanide-based pesticide that was used for the mass killings in the Birkenau gas chambers. He served in this capacity at the gas chambers located in crematoria IV and V.[36]
