Of the seven people who hid in the secret annex, only Otto Frank survived. Upon returning to Amsterdam on June 3, he discovered that his employees had faithfully kept his business running, awaiting his return. He stayed with Miep Gies and her husband and immediately began searching for his daughters—in mid-July, he learned of their deaths at Bergen-Belsen.
Upon arrival at Auschwitz, the SS forcibly separated the men from the women and children, and Otto Frank was wrenched from his family. Those deemed able to work were admitted into the camp, and those deemed unfit for labour were immediately killed. Of the 1,019 passengers, 549—including all children younger than 15—were sent directly to the gas chambers. Anne Frank, who had turned 15 three months earlier, was one of the youngest people spared from her transport. She was soon made aware that most people were gassed upon arrival and never learned that the entire group from the Achterhuis had survived this selection. She reasoned that her father, in his mid-fifties and not particularly robust, had been killed immediately after they were separated.
Nazi racial theorist Hans F. K. Günther argued that European peoples were divided into five races: Nordic, Mediterranean, Dinaric, Alpine and East Baltic. Günther applied a Nordicist conception in order to justify his belief that Nordics were the highest in the racial hierarchy. In his book Rassenkunde des deutschen Volkes (1922) ("Racial Science of the German People"), Günther recognised Germans as being composed of all five races, but emphasized the strong Nordic heritage among them. Hitler read Rassenkunde des deutschen Volkes, which influenced his racial policy. Gunther believed that Slavs belonged to an "Eastern race" and he warned against Germans mixing with them. The Nazis described Jews as being a racially mixed group of primarily Near Eastern and Oriental racial types. Because such racial groups were concentrated outside Europe, the Nazis claimed that Jews were "racially alien" to all European peoples and that they did not have deep racial roots in Europe.
In May 1940, Germany invaded the Netherlands, and the occupation government began to persecute Jews by the implementation of restrictive and discriminatory laws; mandatory registration and segregation soon followed. Otto Frank tried to arrange for the family to emigrate to the United States – the only destination that seemed to him to be viable – but Frank's application for a visa was never processed, due to circumstances such as the closing of the U.S. consulate in Rotterdam and the loss of all the paperwork there, including the visa application. Even if it had been processed, the U.S. government at the time was concerned that people with close relatives still in Germany could be blackmailed into becoming Nazi spies.
On 3 May 1957, a group of citizens, including Otto Frank, established the Anne Frank Stichting in an effort to rescue the Prinsengracht building from demolition and to make it accessible to the public. The Anne Frank House opened on 3 May 1960. It consists of the Opekta warehouse and offices and the Achterhuis, all unfurnished so that visitors can walk freely through the rooms. Some personal relics of the former occupants remain, such as movie star photographs glued by Anne to a wall, a section of wallpaper on which Otto Frank marked the height of his growing daughters, and a map on the wall where he recorded the advance of the Allied Forces, all now protected behind acrylic glass. From the small room which was once home to Peter van Pels, a walkway connects the building to its neighbours, also purchased by the Foundation. These other buildings are used to house the diary, as well as rotating exhibits that chronicle aspects of the Holocaust and more contemporary examinations of racial intolerance around the world. One of Amsterdam's main tourist attractions, it received a record 965,000 visitors in 2005. The House provides information via the internet and offers exhibitions that in 2005 travelled to 32 countries in Europe, Asia, North America, and South America.
In early November 1944, Anne was put on transport again. Together with her sister, she was deported to the Bergen-Belsen concentration camp. Her parents stayed behind in Auschwitz. The conditions in Bergen-Belsen were horrible, too, there was a lack of food, it was cold, and Anne, like her sister, contracted typhus. In February 1945 they both died owing to its effects, Margot first, Anne shortly afterwards.
Nazi Germany maintained concentration camps (German: Konzentrationslager, KZ or KL) throughout the territories it controlled before and during the Second World War. The first Nazi camps were erected in Germany in March 1933 immediately after Hitler became Chancellor and his Nazi Party was given control of the police by Reich Interior Minister Wilhelm Frick and Prussian Acting Interior Minister Hermann Göring. Used to hold and torture political opponents and union organizers, the camps initially held around 45,000 prisoners. In 1933–1939, before the onset of war, most prisoners consisted of German Communists, Socialists, Social Democrats, Roma, Jehovah's Witnesses, homosexuals, and persons accused of 'asocial' or socially 'deviant' behavior by the Germans.
