At the age of 22, Jack Eisner moved to the United States, where he established what eventually became a highly successful international trade company. In the aftermath of World War II, he helped the U.S. government track war criminals and served as a witness at the trials of Nazis at Dachau. He was one of the founders of the Warsaw Ghetto Resistance Organization, which commemorates the uprising every April across the nation. To disseminate the true story of the Holocaust, he established the Holocaust Survivors Memorial Foundation, which warned of the lessons of antisemitism through the arts and endowed chairs at universities. And perhaps most poignantly, he created a permanent monument in the Warsaw Jewish Cemetery dedicated to the memory of the Jewish children murdered during the Holocaust. The Survivor of the Holocaust was adapted into a play entitled The Survivor, which ran on Broadway, and it also inspired the film War and Love.
