More than 140 years after Louis Braille invented the Braille reading system, Seiichi Miyake came up with a different system based on touch that allows visually impaired people to navigate public spaces. Today, tactile paving is used by major cities and transportation services around the world. Miyake was so influential that he's the subject of the Google Doodle for March 18, the 52nd anniversary of tactile paving's debut.
Soviet civilian populations in the occupied areas were heavily persecuted.[438] Villages throughout the Soviet Union were destroyed by German troops.[439] Germans rounded up civilians for forced labor in Germany and caused famine by taking foodstuffs.[440] In Belarus, Germany imposed a regime that deported some 380,000 people for slave labor and killed hundreds of thousands of civilians. Over 600 villages had their entire populations killed, and at least 5,295 Belarusian settlements were destroyed by the Germans. According to Timothy Snyder, of "the nine million people who were in the territory of Soviet Belarus in 1941, some 1.6 million were killed by the Germans in actions away from battlefields, including about 700,000 prisoners of war, 500,000 Jews, and 320,000 people counted as partisans (the vast majority of whom were unarmed civilians)".[441] The United States Holocaust Memorial Museum has estimated that 3.3 million of 5.7 million Soviet POWs died in German custody.[442] The death rates decreased as the POWs were needed to help the German war effort; by 1943, half a million had been deployed as slave labor.[409]
After the German invasion of Czechoslovakia in 1939, the Nazis sent many thousands of Czech Jews to ghettos in Poland, Lithuania and Latvia. On 22 June 1941, the German invasion of the Soviet Union brought many more Jews within the German sphere of influence. Some Polish Jews had managed to escape into the Soviet Union during the German invasion of Poland. Now, as the German army rolled into the Soviet Union, they were again trapped.

On January 20, 1942, Reinhard Heydrich convened the Wannsee Conference at a lakeside villa in Berlin to organize the “final solution to the Jewish question.” Around the table were 15 men representing government agencies necessary to implement so bold and sweeping a policy. The language of the meeting was clear, but the meeting notes were circumspect:
Man blinded by continuous beatings  © The ideas and emotions that lay behind the Holocaust were not new, nor were they uniquely German. The Nazis were the heirs of a centuries-old tradition of Jew-hatred, rooted in religious rivalry and found in all European countries. When the Nazis came to carry out their genocidal programme, they found collaborators in all the countries they dominated, including governments that enjoyed considerable public support. Most people drew the line at mass murder, but relatively few could be found to oppose it actively or to extend help to the Jews.
“I’ve offered three possibilities” to the museum, Freund said. The first was to try to partially excavate one section of the tunnel and protect it with climate-controlling plexiglass walls. Alternatively, a re-creation could be built, as had been done with the recently finished facsimile of King Tutankhamun’s tomb, in the Valley of the Kings, in Egypt. The last option, Freund allowed, was a “little futuristic”: Relying on the data from the scans, a 3-D film could be created so visitors could relive the experience of the escape.
In the summer of 1941, Rudolf Höss, the commandant of Auschwitz, received orders from Heinrich Himmler to begin experimenting with Zyklon B gas. On 3 September 1941, the Auschwitz deputy camp commandant Karl Fritzsch experimented on 600 Russian prisoners of war and 250 Polish inmates by gathering them in the basement of Block 11 and gassing them with Zyklon B.
The match was perfect. The video image of the photograph was imposed precisely over the video image of the skull. It was a face wrapped over a skull, subject over object, an image of life over an image of death. While the images helped to push the probability calculation further in the direction of a definitive identification, they did more than that, for it was the appearance of a previously unseen image that produced the potential for conviction.
The mass killings of Jews in the occupied Soviet territories were assigned to four SS formations called Einsatzgruppen ("task groups"), which were under Heydrich's overall command. Similar formations had been used to a limited extent in Poland in 1939, but the ones operating in the Soviet territories were much larger.[242] The Einsatzgruppen's commanders were ordinary citizens: the great majority were professionals and most were intellectuals.[243] By the winter of 1941–1942, the four Einsatzgruppen and their helpers had killed almost 500,000 people.[244] The largest massacre of Jews by the mobile killing squads in the Soviet Union was at a ravine called Babi Yar outside Kiev,[245] where 33,771 Jews were killed in a single operation on 29–30 September 1941.[246][n] A mixture of SS and Security Police, assisted by Ukrainian police, carried out the killings.[248] Although they did not actively participate in the killings, men of the German 6th Army helped round up the Jews of Kiev and transport them to be shot.[249] By the end of the war, around two million are thought to have been victims of the Einsatzgruppen and their helpers in the local population and the German Army. Of those, about 1.3 million were Jews and up to a quarter of a million Roma.[250]
Throughout the spring and summer of 1940, the German army expanded Hitler’s empire in Europe, conquering Denmark, Norway, the Netherlands, Belgium, Luxembourg and France. Beginning in 1941, Jews from all over the continent, as well as hundreds of thousands of European Gypsies, were transported to the Polish ghettoes. The German invasion of the Soviet Union in June 1941 marked a new level of brutality in warfare. Mobile killing units called Einsatzgruppenwould murder more than 500,000 Soviet Jews and others (usually by shooting) over the course of the German occupation.

Auschwitz, perhaps the most notorious and lethal of the concentration camps, was actually three camps in one: a prison camp (Auschwitz I), an extermination camp (Auschwitz II–Birkenau), and a slave labour camp (Auschwitz III–Buna-Monowitz). Upon arrival, Jewish prisoners faced what was called a Selektion. A German doctor presided over the selection of pregnant women, young children, the elderly, handicapped, sick, and infirm for immediate death in the gas chambers. As necessary, the Germans selected able-bodied prisoners for forced labour in the factories adjacent to Auschwitz, where one German company, IG Farben, invested 700 million Reichsmarks in 1942 alone to take advantage of forced labour, a capital investment. The conglomerate presumed that slave labour would be a permanent part of the German economy. Deprived of adequate food, shelter, clothing, and medical care, these prisoners were literally worked to death. Periodically, they would face another Selektion. The Nazis would transfer those unable to work to the gas chambers of Birkenau.
Perhaps Miep Gies, the woman who sheltered Anne Frank and her family, explained the actions of Righteous Gentiles best. “My decision to help Otto [Frank] was because I saw no alternative. I could foresee many sleepless nights and an unhappy life if I refused. And that was not the kind of failure I wanted for myself. Permanent remorse about failing to do your human duty, in my opinion, can be worse than losing your life.”

In August 1944, they were discovered and deported to Nazi concentration camps. They were long thought to have been betrayed, although there are indications that their discovery may have been accidental, that the police raid had actually targeted "ration fraud".[14] Of the eight people, only Otto Frank, the oldest, survived the war. Anne died when she was 15 years old in Bergen-Belsen, from typhus. The exact date of her death is unknown, and has long been believed to be in early March, a few weeks before the prisoners were liberated by British troops in April 1945. However, research in 2015 indicated that Anne may have died in February.[15]
Once the Nazis took over Budapest in 1944 and began deporting Jews to the death camps, Lutz negotiated a special deal with the Hungarian government and the Nazis: he had permission to issue protective letters to 8,000 Hungarian Jews for emigration to Palestine. Lutz then deliberately misinterpreted his permission for 8,000 as applying to families rather than individuals, and proceeded to issue tens of thousands of additional protective letters, all of them bearing a number between one and 8,000. He also set up some 76 safe houses around Budapest, declaring them annexes of the Swiss legation. Among the safe houses was the now well-known "Glass House" (Üvegház) at Vadász Street 29. About 3,000 Jews found refuge at the Glass House and in a neighboring building.

Center for Advanced Holocaust Studies, United States Holocaust Memorial Museum. Pages 110–122 in PDF. Ukraine differs from other parts of the Nazi-occupied Soviet Union, whereas the local administrators have formed the Hilfsverwaltung in support of extermination policies in 1941 and 1942, and in providing assistance for the deportations to camps in Germany mainly in 1942 and 1943.
Anne Frank and her family fled Germany after the Nazis seized power in 1933 and resettled in the Netherlands, where her father, Otto, had business connections. The Germans occupied Amsterdam in May 1940, and two years later German authorities with help from their Dutch collaborators began rounding up Jews and ultimately deported them to killing centers.
The same year, the Mossad hoped to tap phone conversations between Mengele and his son, Rolf, who was living in West Berlin. The two were born on the same day, and the Israelis hoped they would call each other to say happy birthday. Cold War Berlin was inundated with spies, and the Mossad preferred when possible not to work there. But they calculated that “this may be the last opportunity” to hear from Mengele. Israeli operatives installed listening devices in Rolf’s home and office, and in his phones.

Mengele's research subjects were better fed and housed than the other prisoners, and temporarily spared from execution in the gas chambers.[42] He established a kindergarten for children who were the subjects of his experiments, as well as the preschool children from the Romani camp. The facility provided better food and living conditions than other areas of the camp, and included a children's playground.[43] When visiting his young subjects, he introduced himself as "Uncle Mengele" and offered them sweets,[44] while at the same time being personally responsible for the deaths of an unknown number of victims whom he killed via lethal injection, shootings, beatings, and his deadly experiments.[45] In his 1986 book, Lifton describes Mengele as sadistic, lacking empathy, and extremely antisemitic, believing the Jews should be eliminated entirely as an inferior and dangerous race.[46] Rolf Mengele later claimed that his father had shown no remorse for his wartime activities.[47]
