At this point, we must remember that some survivors were unable to return to "normal" life after the trauma of the Holocaust. Among this group were survivors who committed suicide, survivors who experienced severe psychological scarring, survivors who were unable to marry or have children, and others who suffered from a host of problems after the Holocaust. What is remarkable is that these were the minority, and that most Holocaust survivors were able to bring a certain degree of order to their chaotic world.
“At this point in the war and in his life, I think Oskar Schindler was absolutely determined to do everything he could to save as many Jews as he could regardless of the cost, either personal or financial,” writes Crowe. “During the last two years of the war, he had undergone a dramatic moral transformation, and, in many ways, he came more and more to associate himself with his Jews than with other Germans.”
Many of the prisoners at Bergen Belsen arrived there on death marches from other concentration camps. During Summer 1944, as the British and American Armies advanced in their fight against Germany from the West and the Soviet army advanced in its fight against Germany from the East, the Nazis began liquidating concentration camps, sending prisoners on death marches. They forced prisoners of concentration camps to march over long distances, under unbearable conditions. Prisoners were abused, and sometimes killed, by the guards that accompanied them. 
That June, Theodor Eicke (1892-1943) replaced Wäckerle as Dachau commandant. Eicke immediately released a set of regulations for the camp’s daily operation. Prisoners deemed guilty of rule breaking were to be brutally beaten. Those who plotted to escape or espoused political views were to be executed on the spot. Prisoners would not be allowed to defend themselves or protest this treatment. Eicke’s regulations served as a blueprint for the operation of all concentration camps in Nazi Germany.
Smith was told by the former inmates of Dachau that "many ambitious projects were undertaken, such as the production of artificial pepper, the evaluation of seasoning mixtures, the extraction of Vitamin C from gladioli and other flowers, the potentiation of plant growth by hormone-enriched manure, and of most importance to Germany, the development of synthetic fertilizer. As a profitable sideline, garlic, malva, and other medicinal plants, and vegetable seeds, were cultivated by the prisoners and then sold; the profits went to the SS."
The Holocaust was the murder by Nazi Germany of six million Jews. While the Nazi persecution of the Jews began in 1933, the mass murder was committed during World War II. It took the Germans and their accomplices four and a half years to murder six million Jews. They were at their most efficient from April to November 1942 – 250 days in which they murdered some two and a half million Jews. They never showed any restraint, they slowed down only when they began to run out of Jews to kill, and they only stopped when the Allies defeated them. More...
For a better sense of reality, Spielberg originally wanted to shoot the movie completely in Polish and German using subtitles, but he eventually decided against it because he felt that it would take away from the urgency and importance of the images onscreen. According to Spielberg, “I wanted people to watch the images, not read the subtitles. There’s too much safety in reading. It would have been an excuse to take their eyes off the screen and watch something else.”

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 Holocaust was the systematic, bureaucratic, state-sponsored persecution and murder of six million Jews by the Nazi regime and its collaborators. Holocaust is a word of Greek origin meaning "sacrifice by fire." The Nazis, who came to power in Germany in January 1933, believed that Germans were "racially superior" and that the Jews, deemed "inferior," were an alien threat to the so-called German racial community.
While Schindler operated two other factories in Krakow, only at Emalia did he employ Jewish workers who resided in the nearby Krakow ghetto. At its peak strength in 1944, Emalia employed 1,700 workers; at least 1,000 were Jewish forced laborers, whom the Germans had relocated from the Krakow ghetto after its liquidation in March 1943 to the forced labor camp and later concentration camp Krakau-Plaszow.
When the wagons were forced open, a terrible sight was revealed. The Schindlers took charge of the 107 survivors, with terrible frostbite and frightfully emaciated, arranged for medical treatment and gradually nourished them back to life. Schindler also stood up to the Nazi Commandant who wanted to incinerate the corpses that were found frozen in the boxcars, and  arranged for their burial with full Jewish religious rites in a plot of land near the Catholic cemetery, which he had especially bought for that purpose.
Oskar Schindler was a German who joined the Nazi Party for business reasons. Before the war, Schindler was known mainly for his interest in making quick money, drinking, and womanizing. Indeed, he saw the war at first as a chance to indulge in all three. Soon after the invasion of Poland, he came to the city of Kraków in search of business opportunities. With equal doses of bribery and charm, he managed to convince the Nazis that he was the right man to take over a failed cookware factory outside the city. He then proceeded to make a fortune turning out mess kits for German soldiers.
Dynatron was Schindler's elevator drive system launched in 1965. It is based on Schlieren's Monotron drive which was developed in 1958. These drive systems are particularly distinguished by direct stopping, regulated electronically as a function of the distance to the floor level. Dynatron should not be confused with Schindler's Dynator (Ward Leonard) drive, which was introduced in 1945.
In April 1943, a part of the Bergen-Belsen camp was taken over by the SS Economic-Administration Main Office (SS Wirtschafts-Verwaltungshauptamt; WVHA). It thus became part of the concentration camp system, run by the SS Schutzstaffel but it was a special case.[7] Having initially been designated a Zivilinterniertenlager ("civilian internment camp"), in June 1943 it was redesignated Aufenthaltslager ("holding camp"), since the Geneva Conventions stipulated that the former type of facility must be open to inspection by international committees.[8] This "holding camp" or "exchange camp" was for Jews who were intended to be exchanged for German civilians interned in other countries, or for hard currency.[9] The SS divided this camp into subsections for individual groups (the "Hungarian camp", the "special camp" for Polish Jews, the "neutrals camp" for citizens of neutral countries and the "Star camp" for Dutch Jews). Between the summer of 1943 and December 1944 at least 14,600 Jews, including 2,750 children and minors were transported to the Bergen-Belsen "holding" or exchange camp.[10]:160 Inmates were made to work, many of them in the "shoe commando" which salvaged usable pieces of leather from shoes collected and brought to the camp from all over Germany and occupied Europe. In general the prisoners of this part of the camp were treated less harshly than some other classes of Bergen-Belsen prisoner until fairly late in the war, due to their perceived potential exchange value.[9] However, only around 2,560 Jewish prisoners were ever actually released from Bergen-Belsen and allowed to leave Germany.[9]
