The Holocaust, the systematic mass murder of European Jewry by the Nazis, is the genocide most thoroughly recorded by the motion picture camera and replayed incessantly thereafter on screens large and small. (Michael Marrus).  One might wonder where did this all begin or how or why?  Basically, the Holocaust begins by outlining the stages in which Nazi racial policies evolved.  In the 1930's, Adolf Hitler sought to exclude Jews, Gypsies, and others he considered to be "racially inferior" from the German community.  During the first two years of WWII, the Nazi state turned to genocide.  What is genocide?  The destruction of a nation or an ethnic group.  He began with the German handicapped, then the Soviet Jews, and finally with all European Jews and Gypsies.  In 1941-1944 the concentration, deportation, enslavement, and extermination of Jews and Gypsies were in full swing. (Niewyk and Nicosia).   Eventually the Germans were defeated and captured, however, six million Jews had already been killed.  This was two-thirds of Europe's Jewish population.  General Dwight D. Eisenhower, the European Allied Commander, insisted that military cameramen document these horrific killings. Therefore, million of Americans got their first look at the human devastation inside the Nazi death camps from newsreels screened in their local movie theaters.  This is how the Holocaust came to be in the movie industry.  Throughout the years, film has defined our public memory of the Holocaust through the historical footage, documentaries, and dramatic films like Murderers Are Among Us (1946), Holocaust (1979), Schindler's List (1993), The Pianist (2002) and many more.
