Eliezer (Elie) Wiesel is arguably the most well known Holocaust survivor. He and his family lived in Sighet, and when Wiesel was sixteen the Wiesels and the other Jews in his community were deported by the German army to concentration camps.
Wiesel spent time in the camps in Auschwitz, Buna, and Buchenwald. The Americans came and liberated the camps, saving all of the prisoners, including Wiesel. Wiesel's tattooed prison number was A-7713.
Since his time in the camps, Wiesel has written books (more than thirty of them, including Night, known and published all over the world), won the Nobel Peace Prize (1986), was responsible for designing the Holocaust Museum in the United States, and speaks regularly about the issue of human rights all over the world. He believes that "...to remain silent and indifferent is the greatest sin of all...."
