Elie Wiesel is a Holocaust survivor and author. He was born in 1928 in Romania and survived Auschwitz and Buchenwald as a teenager. His most famous book, Night, describes his experiences in the concentration camps during World War II and the horrors he witnessed, including the death of his father. After the war, Wiesel became a professor and advocate for human rights, receiving the Nobel Peace Prize in 1986 for raising awareness about the Holocaust. Night is relevant to understanding World War II because it provides a first-hand account of the suffering inflicted upon Jews by the Nazis in the concentration camps.
