Although the phrase "Righteous Gentiles" has become a general term for any non-Jew who risked their life to save Jews during the Holocaust, it here appears to apply specifically to: Raoul Wallenberg [Swedish, d. 1947] Hiram Bingham IV [d. 1988, American]; Karl Lutz [d. 1975, Swiss]; C. Sujihara [d. 1986, Japanese]; and Andre Trocme [d. 1971, French].
Bartoszewski was a founder of the Polish resistance who organized an underground organization, comprised mostly of Catholics, to help save Jews. He worked to provide false documents to Jews living outside the Warsaw ghetto. In the fall of 1942, he helped found an organization (Council for Aid to Jews) which successfully saved many Jews from the gas chambers. Bartoszweski was actually imprisoned in the Auschwitz Concentration Camp between 1940 and 1941, and after his release was secured by the Red Cross he reported on the camp.
Under the Nuremberg Laws, Jews became routine targets for stigmatization and persecution. This culminated in Kristallnacht, or the “night of broken glass” in November 1938, when German synagogues were burned and windows in Jewish shops were smashed; some 100 Jews were killed and thousands more arrested. From 1933 to 1939, hundreds of thousands of Jews who were able to leave Germany did, while those who remained lived in a constant state of uncertainty and fear.

An SS report described the scene: "The Jews stayed in the burning buildings until because of the fear of being burned alive they jumped down from the upper stories…With their bones broken, they still tried to crawl across the street into buildings which had not yet been set on fire…Despite the danger of being burned alive the Jews and bandits often preferred to return into the flames rather than risk being caught by us."
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]

From the Kristallnacht pogrom onwards, Nazi policy toward the Jews radicalized relentlessly, reaching deliberate continental genocide of a kind never before seen in history by 1941-1942. It is here, however, that considerable difference of opinion among historians begins. Over the past twenty years or so, a consensus has emerged that Hitler did not embark on his campaign of killing all Jews in the Soviet Union, including women and children, immediately after the invasion began in June 1941, but only several months later. At first, it seems, only adult male Jews and “commissars” (Soviet state operatives) were killed; one of the best-known recent expositions of this viewpoint is Philippe Burrin’s 1994 Hitler and the Jews: The Genesis of the Holocaust . Nearly all of the detailed documentation of the Holocaust, including recently discovered records, points to this conclusion. Nonetheless, by the end of 1941, Nazi killing squads ( Einsatzgruppen ) had killed hundreds of thousands of Jews in the western Soviet Union, murdering men, women, and children indiscriminately. Beginning in early 1942, the extermination camps (all located in conquered Poland) began to murder Jews, and others, brought in from all parts of Europe.
Perhaps not even a father is justified in thinking he can distill the “ideas” of this alert and sorrowing child, with scenes such as these inscribed in her psyche, and with the desolations of Auschwitz and Bergen-Belsen still ahead. His preference was to accentuate what he called Anne’s “optimistical view on life.” Yet the diary’s most celebrated line (infamously celebrated, one might add)—“I still believe, in spite of everything, that people are truly good at heart”—has been torn out of its bed of thorns. Two sentences later (and three weeks before she was seized and shipped to Westerbork), the diarist sets down a vision of darkness:
They were dependent on the general political and military situation. Helping Jews was thus more successful as liberation approached than in the early days of the war. Later in the war, the time required in hiding was shorter, support from local resistance movements was better organized, and the degree of popular hostility to rescue was muted by imminent military defeat.

Before the start of World War II, around 9.5 million Jewish people lived in Europe. By the time the war ended, the Nazis had killed 6 million European Jews in concentration camps, or pogroms, or ghettos, or mass executions in what we refer to today as the Holocaust. The Nazis used the term Endlösung, or Final Solution, as the “answer” to the “Jewish question.” But when did this monstrous plan get put in motion?
After the end of World War II, surviving archival documents provided a clear record of the Final Solution policies and actions of Nazi Germany. They included the Wannsee Conference Protocol, which documented the co-operation of various German state agencies in the SS-led Holocaust, as well as some 3,000 tons of original German records captured by Allied armies,[23][29] including the Einsatzgruppen reports, which documented the progress of the mobile killing units assigned, among other tasks, to kill Jewish civilians during the attack on the Soviet Union in 1941. The evidential proof which documented the mechanism of the Holocaust was submitted at Nuremberg.[29]
Dr Daniel Romero Muñoz, who led the team that identified Mengele’s remains in 1985, saw an opportunity to put them to use. Several months ago, the head of the department of legal medicine at the University of São Paulo’s Medical School obtained permission to use them in his forensic medical courses. Today, his students are now learning their trade studying Mengele’s bones and connecting them to the life story of the man called the “angel of death”.
On March 28, 1944, a radio broadcast from the Dutch government-in-exile in London urged the Dutch people to keep diaries, letters, and other items that would document life under German occupation. Prompted by this announcement, Anne began to edit her diary, hoping to publish it after the war under the title "The Secret Annex." From May 20 until her arrest on August 4, 1944, she transferred nearly two-thirds of her diary from her original notebooks to loose pages, making various revisions in the process.
Mengele’s crimes had been well documented before the International Military Tribunal (IMT) and other postwar courts. West German authorities issued a warrant for his arrest in 1959, and a request for extradition in 1960. Alarmed by the capture of Adolf Eichmann in Buenos Aires in that same year, Mengele moved to Paraguay and then to Brazil. He spent the last years of his life near Sao Pãolo. In declining health, Mengele suffered a stroke and drowned while swimming at a vacation resort near Bertioga, Brazil, on February 7, 1979. He was buried in a suburb of Sao Pãolo under the fictive name “Wolfgang Gerhard.”

Browning wrestles with these and many other related questions in a consistently persuasive and cogent way. He concludes, very sensibly, that it is inconceivable that the Holocaust, unprecedented in history and entailing a massive, counterproductive diversion of resources in wartime, could have taken place without Hitler’s immediate knowledge and approval, although his orders were often, as Browning notes, “vague and inexplicit.” Moreover, Hitler himself was the chief Nazi ideologue of rabid, demented, racialist anti-Semitism, with anti-Semitism at the very center of his worldview and in and of itself a central motivating factor in his foreign and military policies.

Anxious to limit immigration to the United States and to maintain good relations with the Vichy government, the State Department actively discouraged diplomats from helping refugees. However, Bingham cooperated in issuing visas and helping refugees escape France. Hiram Bingham gave about 2,000 visas, most of them to well-known personalities, speaking English, including Max Ernst, André Breton, Hannah Arendt, Marc Chagall, Lion Feuchtwanger and Nobel prize winner Otto Meyerhof.
The Germans required each ghetto to be run by a Judenrat, or Jewish council.[205] Councils were responsible for a ghetto's day-to-day operations, including distributing food, water, heat, medical care, and shelter. The Germans also required councils to confiscate property, organize forced labor, and, finally, facilitate deportations to extermination camps.[206] The councils' basic strategy was one of trying to minimize losses, by cooperating with German authorities, bribing officials, and petitioning for better conditions or clemency.[207]
By now, experimental mobile gas vans were being used by the Einsatzgruppen to kill Jews in Russia. Special trucks had been converted by the SS into portable gas chambers. Jews were locked up in the air-tight rear container while exhaust fumes from the truck's engine were fed in to suffocate them. However, this method was found to be somewhat impractical since the average capacity was less than 50 persons. For the time being, the quickest killing method continued to be mass shootings. And as Hitler's troops advanced deep into the Soviet Union, the pace of Einsatz killings accelerated. Over 33,000 Jews in the Ukraine were shot in the Babi Yar ravine near Kiev during two days in September 1941.

Mengele injected chemicals into the eyes of children in an attempt to change their eye color. Unfortunately a strict veil of secrecy over the experiments enabled Mengele to do his work more effectively.The full extent of his gruesome work will never be known because the records he sent to Dr. Von Verschuer at the Kaiser Wilhelm Institute were shipped out in two truckloads and destroyed by the latter.

When Germany invaded Poland in September 1939, it gained control of about 2 million Jews in the occupied territory. The rest of Poland was occupied by the Soviet Union, which had control of the rest of Poland's pre-war population of 3.3–3.5 million Jews.[141] German plans for Poland included expelling gentile Poles from large areas, confining Jews, and settling Germans on the emptied lands.[142] The Germans initiated a policy of sending Jews from all territories they had recently annexed (Austria, Czechoslovakia, and western Poland) to the central section of Poland, which they called the General Government. There, the Jews were concentrated in ghettos in major cities,[143] chosen for their railway lines to facilitate later deportation.[144] Food supplies were restricted, public hygiene was difficult, and the inhabitants were often subjected to forced labor.[145] In the work camps and ghettos, at least half a million Jews died of starvation, disease, and poor living conditions.[146] Jeremy Black writes that the ghettos were not intended, in 1939, as a step towards the extermination of the Jews. Instead, they were viewed as part of a policy of creating a territorial reservation to contain them.[147][l]
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.
Italy introduced some antisemitic measures, but there was less antisemitism there than in Germany, and Italian-occupied countries were generally safer for Jews than German-occupied territories. In some areas, the Italian authorities even tried to protect Jews, such as in the Croatian areas of the Balkans. But while Italian forces in Russia were not as vicious towards Jews as the Germans, they did not try to stop German atrocities either. There were no deportations of Italian Jews to Germany while Italy remained an ally.[171] Several forced labor camps for Jews were established in Italian-controlled Libya. Almost 2,600 Libyan Jews were sent to camps, where 562 died.[172]

The first such extermination camps were introduced during Operation Reinhardt, which targeted the elimination of the Jewish people within the General Government of Occupied Poland and Ukraine. After the first killing center open at Chelmno, the use of these extermination tactics spread quickly. At the height of deportations, the Birkenau killing center murdered 6,000 Jews a day.
In addition to active help, many clergymen also protested the mistreatment and deportations of Jews as violations of divine and human laws. The Catholic pastor of St. Hedwig’s Cathedral in Berlin, Bernard Lichtenburg, prayed publicly for the Jews until his arrest and death on the way to Dachau. The rescue work of priests of all Christian denominations is well-documented in postwar literature.
As the unsuspecting people were herded off the train and ordered into separate lines, SS officers shouted in German, "Zwillinge!" (Twins!). Parents were forced to make a quick decision. Unsure of their situation, already being separated from family members when forced to form lines, seeing barbed wire, smelling an unfamiliar stench -- was it good or bad to be a twin?

For the first time, it’s possible to say why the Mossad failed to apprehend the man who was perhaps the most wanted Nazi to survive World War II. Documents and interviews reveal that contrary to popular belief, for most of the time that Mengele was in hiding, the Mossad wasn’t looking for him at all — or placed finding him far down its to-do list. My new research sheds light on a time when realism and maturity shaped the agency’s priorities, rather than an understandable desire to spill Nazi blood.

Holocaust scholar and Christian ethicist David Gushee highlighted other traits in his book, Righteous Gentiles of the Holocaust. “Some rescuers appear to have been adventuresome types, and others drew upon a sense of social marginality as a resource for compassion. Another mark of rescuer character is the nearly universal unwillingness to accept praise for their deeds. ‘It is what anyone would have done,’ they say of behaviour that almost no one did. For them to rescue Jews was the perfectly natural and obvious course of action. People needed help. So help was offered.”
Most Holocaust historians define the Holocaust as the enactment, between 1941 and 1945, of the German state policy to exterminate the European Jews.[a] In Teaching the Holocaust (2015), Michael Gray, a specialist in Holocaust education,[27] offers three definitions: (a) "the persecution and murder of Jews by the Nazis and their collaborators between 1933 and 1945", which views the events of Kristallnacht in Germany in 1938 as an early phase of the Holocaust; (b) "the systematic mass murder of the Jews by the Nazi regime and its collaborators between 1941 and 1945", which acknowledges the shift in German policy in 1941 toward the extermination of the Jewish people in Europe; and (c) "the persecution and murder of various groups by the Nazi regime and its collaborators between 1933 and 1945", which includes all the Nazis' victims. The third definition fails, Gray writes, to acknowledge that only the Jewish people were singled out for annihilation.[28]
The word “Holocaust,” from the Greek words “holos” (whole) and “kaustos” (burned), was historically used to describe a sacrificial offering burned on an altar. Since 1945, the word has taken on a new and horrible meaning: the mass murder of some 6 million European Jews (as well as millions of others, including Gypsies and homosexuals) by the German Nazi regime during the Second World War. To the anti-Semitic Nazi leader Adolf Hitler, Jews were an inferior race, an alien threat to German racial purity and community. After years of Nazi rule in Germany, during which Jews were consistently persecuted, Hitler’s “final solution”–now known as the Holocaust–came to fruition under the cover of world war, with mass killing centers constructed in the concentration camps of occupied Poland.
It may be, though, that a new production, even now, and even with cautious additions, will be heard in the play’s original voice. It was always a voice of good will; it meant, as we say, well—and, financially, it certainly did well. But it was Broadway’s style of good will, and that, at least for Meyer Levin, had the scent of ill. For him, and signally for Bloomgarden and Kanin, the most sensitive point—the focus of trouble—lay in the ancient dispute between the particular and the universal. All that was a distraction from the heart of the matter: in a drama about hiding, evil was hidden. And if the play remains essentially as the Hacketts wrote it, the likelihood is that Anne Frank’s real history will hardly prevail over what was experienced, forty years ago, as history transcended, ennobled, rarefied. The first hint is already in the air, puffed by the play’s young lead: It’s funny, it’s hopeful, and she’s a happy person.
The Polish government-in-exile in London learned about the extermination camps from the Polish leadership in Warsaw, who from 1940 "received a continual flow of information about Auschwitz", according to historian Michael Fleming.[333] This was in large measure thanks to Captain Witold Pilecki of the Polish Home Army, who allowed himself to be arrested in Warsaw and spent 945 days in Auschwitz from September 1940 until April 1943, organizing the resistance movement inside the camp.[334]

As an act of honor to those gentiles, Rani composed a Yizkor prayer in their memory. It is unique and breaks new ground. It extends the understanding of relationships between Jews and non-Jews. It remembers that “righteousness is an everlasting foundation” that breaks boundaries. May we reach a day where the example set by those righteous people will not be an extraordinary courageous act, but simply, the norm.
In the last months of Hitler’s Reich, as the German armies retreated, the Nazis began marching the prisoners still alive in the concentration camps to the territory they still controlled. The Germans forced the starving and sick Jews to walk hundreds of miles. Most died or were shot along the way. About a quarter of a million Jews died on the death marches.
Resistance also occurred inside the death camps. At Treblinka, Jewish inmates staged a revolt in August 1943, after which Himmler ordered the camp dismantled. At Sobibor, a big escape occurred in October 1943, as Jews and Soviet POWs killed 11 SS men and broke out, with 300 making it safely into nearby woods. Of those 300, most were hunted down and only fifty survived. Himmler then closed Sobibor. At Auschwitz-Birkenau, Jewish Sonderkommandos managed to destroy crematory number four in October 1944.
Trainloads of human cargo arriving at Auschwitz went through a selection process conducted by SS doctors such as Josef Mengele. Young adults considered fit for slave labor were allowed to live and had an ID number tattooed on their left forearm. Everyone else went to the gas chambers. A few inmates, including twin children, were occasionally set aside for participation in human medical experiments.
As the mass shootings continued in Russia, the Germans began to search for new methods of mass murder. This was driven by a need to have a more efficient method than simply shooting millions of victims. Himmler also feared that the mass shootings were causing psychological problems in the SS. His concerns were shared by his subordinates in the field.[251] In December 1939 and January 1940, another method besides shooting was tried. Experimental gas vans equipped with gas cylinders and a sealed compartment were used to kill the disabled and mentally-ill in occupied Poland.[252] Similar vans, but using the exhaust fumes rather than bottled gas, were introduced to the Chełmno extermination camp in December 1941,[253] and some were used in the occupied Soviet Union, for example in smaller clearing actions in the Minsk ghetto.[254] They also were used for murder in Yugoslavia.[255]
Some ghettos were initially open, which meant that Jews could leave the area during the daytime but had to be back by a curfew. Later, all ghettos became closed, meaning that Jews were not allowed to leave under any circumstances. Major ghettos were located in the cities of Polish cities of Bialystok, Lodz, and Warsaw. Other ghettos were found in present-day Minsk, Belarus; Riga, Latvia; and Vilna, Lithuania. The largest ghetto was in Warsaw. At its peak in March 1941, some 445,000 were crammed into an area just 1.3 square miles in size.

“There is no stopping them [the Jews]. Are there no clear signs that the twilight of the Jews is setting in? No. Jewry’s control of society and politics as well as its domination of religious and ecclesiastical thought is still in the prime of its development. Yes, through the Jewish nation Germany will become a world power, a western new Palestine. And this will happen not through violent revolution but through the compliance of the people. We should not reproach the Jewish nation. It fought against the western world for 1,800 years and finally conquered it. We were vanquished. The Jews were late in their assault on Germany but once started there was no stopping them
In his bunker, in the Chancellory building in Berlin, knowing that the war was lost and that the “1,000 Year Reich” had lasted only a few years, Hitler committed suicide hours after marrying Eva Braun. Germany formally surrendered to the Allies on May 7, 1945. By the end of the war, more than 55 million had died and 35 million wounded. Only 17 million of the dead were soldiers.
Anne Frank’s final diary entry, written on August 1, 1944, ends introspectively—a meditation on a struggle for moral transcendence set down in a mood of wistful gloom. It speaks of “turning my heart inside out, the bad part on the outside and the good part on the inside,” and of “trying to find a way to become what I’d like to be and what I could be if . . . if only there were no other people in the world.” Those curiously self-subduing ellipses are the diarist’s own; they are more than merely a literary effect—they signify a child’s muffled bleat against confinement, the last whimper of a prisoner in a cage. Her circumscribed world had a population of eleven—the three Dutch protectors who came and went, supplying the necessities of life, and the eight in hiding: the van Daans, their son Peter, Albert Dussel, and the four Franks. Five months earlier, on May 26, 1944, she had railed against the stress of living invisibly—a tension never relieved, she asserted, “not once in the two years we’ve been here. How much longer will this increasingly oppressive, unbearable weight press down on us?” And, several paragraphs on, “What will we do if we’re ever . . . no, I mustn’t write that down. But the question won’t let itself be pushed to the back of my mind today; on the contrary, all the fear I’ve ever felt is looming before me in all its horror. . . . I’ve asked myself again and again whether it wouldn’t have been better if we hadn’t gone into hiding, if we were dead now and didn’t have to go through this misery. . . . Let something happen soon. . . . Nothing can be more crushing than this anxiety. Let the end come, however cruel.” And on April 11, 1944; “We are Jews in chains.”
The Diary of a Young Girl as told by Anne Frank is haunting, poignant and beautiful, with a keen sense of hope throughout. Anne documented her family's plight of having to go into hiding in 1942 due to the German invasion in the Netherlands as part of WW2. The Franks were hidden in a secret annexe, behind a bookcase covering a hidden entrance. Not only were the Franks living there, but also another four people. During this time all members of the hidden ...more
The Warsaw Ghetto Uprising was the largest ghetto revolt. Massive deportations (or Aktions) had been held in the ghetto from July to September 1942, emptying the ghetto of the majority of Jews imprisoned there. When the Germans entered the ghetto again in January 1943 to remove several thousand more, small unorganized groups of Jews attacked them. After four days, the Germans withdrew from the ghetto, having deported far fewer people than they had intended. The Nazis reentered the ghetto on April 19, 1943, the eve of Passover, to evacuate the remaining Jews and close the ghetto. The Jews, using homemade bombs and stolen or bartered weapons, resisted and withstood the Germans for 27 days. They fought from bunkers and sewers and evaded capture until the Germans burned the ghetto building by building. By May 16 the ghetto was in ruins and the uprising crushed.

  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.

Although Yad Vashem (Israel’s Memorial to the Six Million) has honored over 1,200 Righteous Among the Nations since 1953, it is impossible to generalize about the motives, deeds, and actual numbers of these rescuers. Some rescuers acted within the planned context of guerrilla units and resistance movements, others used the buildings and funds of the Roman Catholic church to aid Jews.

Lay Catholics, such as the German Dr. Gertrude Luckner, who headed the Caritas Catholica, also extended help to Jews and non-Aryan Christians in Germany. She was deported to Ravensbruck for her aid to the persecuted. After the war, Dr. Luckner was honored for her courage by the Israeli government. It must be noted that much of this Christian help was actually rendered to fellow Christians (converted Jews), who were classified as Jews due to their descent under Nazi racial laws.
While the Nazis murdered other national and ethnic groups, such as a number of Soviet prisoners of war, Polish intellectuals, and gypsies, only the Jews were marked for systematic and total annihilation. Jews were singled out for "Special Treatment" (Sonderbehandlung), which meant that Jewish men, women and children were to be methodically killed with poisonous gas. In the exacting records kept at the Auschwitz death camp, the cause of death of Jews who had been gassed was indicated by "SB," the first letters of the two words that form the German term for "Special Treatment."
On April 17, 1944, Anne began writing in what turned out to be her final diary notebook. On the first page she wrote about herself: "The owner's maxim: Zest is what man needs!" A few months later, she and the other inhabitants of the annex celebrated the Allied invasion of France, which took place on June 6, 1944. They were certain the war would soon be over.

In the eyes of the world, we’re doomed, but if after all this suffering, there are still Jews left, the Jewish people will be held up as an example. Who knows, maybe our religion will teach the world and all the people in it about goodness, and that’s the reason, the only reason, we have to suffer. . . . God has never deserted our people. Through the ages Jews have had to suffer, but through the ages they’ve gone on living, and the centuries of suffering have only made them stronger.
More camps opened in the spring and summer of 1942, when the Nazis began systematically clearing the ghettos in Poland and rounding up Jews in western Europe for 'deportation to the East'. The killing of the Polish Jews, code-named 'Project Reinhardt', was carried out in three camps: Treblinka, near Warsaw (850,000 victims); Belzec, in south-eastern Poland (650,000 victims); and Sobibor, in east-central Poland (250,000 victims). Some Jews from western Europe were sometimes taken to these camps as well, but most were killed at the biggest and most advanced of the death camps, Auschwitz.
Twins were subjected to weekly examinations and measurements of their physical attributes by Mengele or one of his assistants.[49] The experiments he performed on twins included unnecessary amputation of limbs, intentionally infecting one twin with typhus or some other disease, and transfusing the blood of one twin into the other. Many of the victims died while undergoing these procedures,[50] and those who survived the experiments were sometimes killed and their bodies dissected once Mengele had no further use for them.[51] Nyiszli recalled one occasion on which Mengele personally killed fourteen twins in one night by injecting their hearts with chloroform.[31] If one twin died from disease, he would kill the other twin to allow comparative post-mortem reports to be produced for research purposes.[52]
