A play written by Elie Wiesel soon after he was freed from Auschwitz will be performed for the first time at Harvard on April 12. Called “The Choice,” the play will debut at Sanders Theatre, directed by Guila Clara Kessous. Why now? 2015 marks the 70th anniversary of the liberation of Auschwitz and the founding of UNESCO, the UN agency designed to promote international collaboration through education, science, and culture. Now 86, Wiesel has written dozens of books, including “Night,” which is based on his experiences as a prisoner at Auschwitz, Buna, and Buchenwald concentration camps. When he was awarded the Nobel Peace Prize in 1986, Wiesel was called a “messenger to mankind.” In a press release, “The Choice” is described as Wiesel’s attempt to explore “the depths of our human capacity to kill” and “an examination of individual human identity and the fine line between innocence and intention.” Kessous said it’s an honor to stage the play. “As fewer and fewer Holocaust survivors can share testament to the atrocities of genocide and in light of the recent terrorist massacre in France,” she said, “transmitting the memory of this genocide to younger generations remains an imperative.” A select number of tickets can be purchased by phone at 617-496-2222 or at the Harvard Box Office on Mass.
