Mengele joined the Nazi Party in 1937 and the Schutzstaffel (SS; protection squadron) in 1938. He received basic training in 1938 with the Gebirgsjäger (light infantry mountain troop) and was called up for service in the Wehrmacht (Nazi armed forces) in June 1940, some months after the outbreak of World War II. He soon volunteered for medical service in the Waffen-SS, the combat arm of the SS, where he served with the rank of SS-Untersturmführer (second lieutenant) in a medical reserve battalion until November 1940. He was next assigned to the SS-Rasse- und Siedlungshauptamt (SS Race and Settlement Main Office) in Poznań, evaluating candidates for Germanization.[18][19]
According to U.S. Holocaust Memorial Museum full statistics for the tragic fate of children who died during the Holocaust will never be known. Some estimates range as high as 1.5 million murdered children. This figure includes more than 1.2 million Jewish children, tens of thousands of Gypsy children and thousands of institutionalized handicapped children who were murdered under Nazi rule in Germany and occupied Europe.
Friday, August 1, marks the 70th anniversary of Anne Frank's final diary entry. Three days later, she was arrested with her family in the "secret annex" of a house in Amsterdam, Netherlands, where they had hidden for two years. She later died at the Bergen-Belsen concentration camp when she was 15. In her diary, Anne describes a 1942 picture of herself: "This is a photo as I would wish myself to look all the time. Then I would maybe have a chance to come to Hollywood." Click through the gallery to see other pages from her diary:
Word History: Totality of destruction has been central to the meaning of holocaust since it first appeared in Middle English in the 1300s, used in reference to the biblical sacrifice in which a male animal was wholly burnt on the altar in worship of God. Holocaust comes from Greek holokauston, "that which is completely burnt," which was a translation of Hebrew 'ōlâ (literally "that which goes up," that is, in smoke). In this sense of "burnt sacrifice," holocaust is still used in some versions of the Bible. In the 1600s, the meaning of holocaust broadened to "something totally consumed by fire," and the word eventually was applied to fires of extreme destructiveness. In the 1900s, holocaust took on a variety of figurative meanings, summarizing the effects of war, rioting, storms, epidemic diseases, and even economic failures. Most of these usages arose after World War II, but it is unclear whether they permitted or resulted from the use of holocaust in reference to the mass murder of European Jews and others by the Nazis. This application of the word occurred as early as 1942, but the phrase the Holocaust did not become established until the late 1950s. Here it parallels and may have been influenced by another Hebrew word, šô'â, "catastrophe" (in English, Shoah). In the Bible šô'â has a range of meanings including "personal ruin or devastation" and "a wasteland or desert." Šô'â was first used to refer to the Nazi slaughter of Jews in 1939, but the phrase haš-šô'â, "the catastrophe," became established only after World War II. Holocaust has also been used to translate ḥurbān, "destruction," another Hebrew word used as a name for the genocide of Jews by the Nazis.

Almost all Jews within areas occupied by the Germans were killed. There were 3,020,000 Jews in the Soviet Union in 1939, and the losses were 1–1.1 million.[400] Around one million Jews were killed by the Einsatzgruppen in the occupied Soviet territories.[401][402] Of Poland's 3.3 million Jews, about 90 percent were killed.[369] Many more died in the ghettos of Poland before they could be deported.[403] The death camps accounted for half the number of Jews killed; 80–90 percent of death-camp victims are estimated to have been Jews.[394] At Auschwitz-Birkenau the Jewish death toll was 1.1 million;[286][404] Treblinka 870,000–925,000;[405] Bełżec 434,000–600,000;[406][287] Chełmno 152,000–320,000;[407][288] Sobibór 170,000–250,000;[408][291] and Majdanek 79,000.[289]
In the early 1990's, Argentine authorities opened its archives to reveal that several Nazi war criminals found safe haven in South America, including Dr. Josef Mengele, also known as Auschwitz’s Angel of Death. Mengele is infamous for his horrific experiments on inmates at the concentration camp. According to The New York Times in 1992, Mengele entered Argentina using a Red Cross-issued passport in 1949 and “practiced medicine in Buenos Aires for several years in the 1950s,” specializing in illegal abortions.
Wounded while on campaign, Mengele returned to Germany in January 1943. He began work at the Kaiser Wilhelm Institute (KWI) for Anthropology, Human Genetics, and Eugenics, directed by his former mentor von Verschuer. In April of 1943, he received a promotion to the rank of SS captain. This promotion shortly preceded Mengele's transfer to Auschwitz, on May 30, 1943.

As of 1 January 2006, Yad Vashem had recognized 21,310 persons as Righteous Gentiles. Poles formed the largest group, with 5,941 having been recognized. Other East Europeans came from Ukraine (2,139), Hungary (671), Lithuania (630), Belarus (564), Slovakia (460), Russia (120), Czech Republic (115), Latvia (100), Moldova (71), Romania (52), and Estonia (3). Yad Vashem cautions, however, that its figures do not represent the actual number of people who rescued Jews in each country. For example, gentiles who saved Jews for financial gain are excluded. Thus many more people rescued Jews than are officially recognized. Because Poles constitute by far the largest group of Righteous Gentiles, they have been the most extensively studied, and most of the following observations are based on data concerning them.
In the Lviv pogroms in occupied Poland in July 1941, some 6,000 Polish Jews were murdered in the streets, on top of 3,000 arrests and mass shootings by Einsatzgruppe C.[231][m] During the Jedwabne pogrom, on 10 July 1941, a group of 40 Polish men killed several hundred Jews; around 300 were burned alive in a barn. The attack is thought to have been organized by the German Security Police (Sicherheitsdienst).[233] A long debate about who was responsible for the Jedwabne murders was triggered in 2001 by the publication of Jan T. Gross's book Neighbors: The Destruction of the Jewish Community in Jedwabne, Poland.[234] The response to the book was described as "the most prolonged and far-reaching of any discussion of the Jewish issue in Poland since the Second World War".[235]
The men selected April 15, the darkest night of the month, for the escape. Dogim, the unofficial leader of the group, was first—once he emerged from the tunnel, he would cut a hole in the nearby fence and mark it with a white cloth, so the others would know which direction to run. Farber was second. Motke Zeidel was sixth. The prisoners knew that a group of partisan fighters were holed up nearby, in the Rudnitsky Woods, in a secret camp from which they launched attacks on the Nazi occupiers. “Remember, there is no going back under any circumstances,” Farber reminded his friends. “It is better to die fighting, so just keep moving forward.”
Mengele was born on 16 March 1911 to Walburga (née Hupfauer) and Karl Mengele in Günzburg, Bavaria, Germany.[4] He was the oldest of three children; his two younger brothers were Karl Jr. and Alois. Their father was founder of the Karl Mengele & Sons company, producers of farm machinery.[5] Josef was successful at school and developed an interest in music, art, and skiing.[6] He completed high school in April 1930 and went on to study philosophy in Munich,[7] where the headquarters of the Nazi Party were located.[8] In 1931, Mengele joined the Stahlhelm, Bund der Frontsoldaten, a paramilitary organization that was absorbed into the Nazi Sturmabteilung (Storm Detachment; SA) in 1934.[7][9]
