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.
The digging got underway the first night in February 1944, in a storeroom at the back of the bunker. To disguise their efforts, the prisoners erected a fake wall over the tunnel’s entrance, with “two boards hanging on loose nails that would come out with a good tug, making it possible to pass through,” Farber recalled in The Complete Black Book of Russian Jewry, a compilation of eyewitness testimonies, letters and other documents of the Nazi campaign against Jews in Eastern Europe published in part in 1944 and translated into English in 2001.
The unstoppable Allied military advance continued and on July 24, 1944, Soviet troops liberated the first camp, Majdanek in eastern Poland, where over 360,000 had died. As the Soviet Army neared Auschwitz, Himmler ordered the complete destruction of the gas chambers. Throughout Hitler's crumbling Reich, the SS now began conducting death marches of surviving concentration camp inmates away from outlying areas, including some 66,000 from Auschwitz. Most of the inmates on these marches either dropped dead from exertion or were shot by the SS when they failed to keep up with the column.
Approximately 30 physicians served at Auschwitz while Mengele was assigned to the camp. As a required part feature of their “rounds,” medical staff performed “selections” of prisoners on the ramp. These selections determined who from among the mass of humanity arriving at Auschwitz would be retained for work and who would perish immediately in the gas chambers.

Richard Freund, an American archaeologist at the University of Hartford, in Connecticut, specializes in Jewish history, modern and ancient. He has been traversing the globe for almost three decades, working at sites as varied as Qumran, where the Dead Sea Scrolls were discovered, and at Sobibor, a Nazi extermination camp in eastern Poland. Unusually for a man in his profession, he rarely puts trowel to earth. Instead, Freund, who is rumpled and stout, with eyes that seem locked in a perpetual squint, practices what he calls “noninvasive archaeology,” which uses ground-penetrating radar and other types of computerized electronic technology to discover and describe structures hidden underground.

An emaciated 18-year-old Russian girl looks into the camera lens during the liberation of Dachau concentration camp in 1945. Dachau was the first German concentration camp, opened in 1933. More than 200,000 people were detained between 1933 and 1945, and 31,591 deaths were declared, most from disease, malnutrition and suicide. Unlike Auschwitz, Dachau was not explicitly an extermination camp, but conditions were so horrific that hundreds died every week. #
Polish gentiles who rescued Jews had several obstacles to overcome. The most serious were the German laws against protecting Jews and the corresponding obligation to identify those who violated these laws. On 15 October 1941, the Nazis introduced a widely publicized law making unauthorized Jewish movement outside ghettos a crime punishable by death. The same punishment applied to gentiles who helped Jews escape. Transgressions were promptly followed by executions that were also widely publicized.
Dr. Josef Mengele, nicknamed The Angel Of Death, and the other Nazi doctors at the death camps tortured men, women and children and did medical experiments of unspeakable horror during the Holocaust. Victims were put into pressure chambers, tested with drugs, castrated, frozen to death. Children were exposed to experimental surgeries performed without anesthesia, transfusions of blood from one to another, isolation endurance, reaction to various stimuli. The doctors made injections with lethal germs, sex change operations, removal of organs and limbs.

Walking the grounds of the memorial site, I arrived with Freund at the lip of the pit that had housed the bunker where Zeidel and the other members of the Burning Brigade had lived. The circumference was tremendous, nearly 200 feet in total. On its grassy floor, the Vilna Gaon Museum had erected a model of a double-sided ramp that the Burning Brigade had used to drop bodies onto the pyres.
For the German rulers, the ghetto was a temporary measure, a holding pen for the Jewish population until a policy on its fate could be established and implemented. For the Jews, ghetto life was the situation under which they thought they would be forced to live until the end of the war. They aimed to make life bearable, even under the most trying circumstances. When the Nazis prohibited schools, they opened clandestine schools. When the Nazis banned religious life, it persisted in hiding. The Jews used humour as a means of defiance, so too song. They resorted to arms only late in the Nazi assault.
The nature and timing of the decisions that led to the Final Solution is an intensely researched and debated aspect of the Holocaust. The program evolved during the first 25 months of war leading to the attempt at "murdering every last Jew in the German grasp".[5] Most historians agree, wrote Christopher Browning, that the Final Solution cannot be attributed to a single decision made at one particular point in time.[5] "It is generally accepted the decision-making process was prolonged and incremental."[6] In 1940, following the Fall of France, Adolf Eichmann devised the Madagascar Plan to move Europe's Jewish population to the French colony, but the plan was abandoned for logistical reasons, mainly a naval blockade.[7] There were also preliminary plans to deport Jews to Palestine and Siberia.[8] In 1941, wrote Raul Hilberg, in the first phase of the mass murder of Jews, the mobile killing units began to pursue their victims across occupied eastern territories; in the second phase, stretching across all of German-occupied Europe, the Jewish victims were sent on death trains to centralized extermination camps built for the purpose of systematic implementation of the Final Solution.[9]
On October 23, 1941, S.S. head Heinrich Himmler issued an order down the Nazi chain of command which heralded a major change in Nazi policy with respect to the “Jewish problem.” Until then, the Nazis worked vigorously to encourage Jews to emigrate. The Madagascar Plan (see below) was one example of strategies which were formulated to remove Jews from Germany and its occupied lands. As is described in more detail in Chapter 11, many countries refused to accept Jewish refugees. This shift in policy resulted in the deportation of Jews to camps and ghettos in the East. The policy to “resettle” Jews to these ghettos and camps was a significant step in what was to become the “Final Solution” the systematic murder of millions of Jews.
Jews were forced to move, often to different cities or countries, and live in designated areas, referred to as ghettos. Most of the ghettos were “open” which meant Jews were free to come and go during the daytime. As time past, more and more ghettos became “closed” meaning that Jews were trapped and not allowed to leave. No ghettos were ever established within the borders of Germany and most were only meant as a temporary means of isolating Jews from the German population until they could be moved elsewhere.

Mengele used Auschwitz as an opportunity to continue his anthropological studies and research into heredity, using inmates for human experimentation.[2] His medical procedures showed no consideration for the health, safety, or physical and emotional suffering of the victims.[2][3] He was particularly interested in identical twins, people with heterochromia iridum (eyes of two different colors), dwarfs, and people with physical abnormalities.[2] A grant was provided by the Deutsche Forschungsgemeinschaft (German Research Foundation), at the request of von Verschuer, who received regular reports and shipments of specimens from Mengele. The grant was used to build a pathology laboratory attached to Crematorium II at Auschwitz II-Birkenau.[38] Dr. Miklós Nyiszli, a Hungarian Jewish pathologist who arrived in Auschwitz on 29 May 1944, performed dissections and prepared specimens for shipment in this laboratory.[39] The twin research was in part intended to prove the supremacy of heredity over environment and thus strengthen the Nazi premise of the superiority of the Aryan race.[40] Nyiszli and others reported that the twin studies may also have been motivated by an intention to increase the reproduction rate of the German race by improving the chances of racially desirable people having twins.[41]
