The world remembers Elie Wiesel—Nobel laureate, activist, and author of more than forty books, including Oprah’s Book Club selection Night—as a great humanist. He passed away in July 2016. Ariel Burger first met Elie Wiesel at age fifteen. They studied and taught together. Witness chronicles the intimate conversations between these two men over decades, as Burger sought counsel on matters of intellect, spirituality, and faith, while navigating his own personal journey from boyhood to manhood, from student and assistant to rabbi and, in time, teacher. In this profoundly hopeful, thought-provoking, and inspiring book, Burger takes us into Elie Wiesel’s classroom, where the art of listening and storytelling conspire to keep memory alive. As Wiesel’s teaching assistant, Burger gives us a front-row seat witnessing these remarkable exchanges in and out of the classroom. The act of listening, of sharing these stories, makes of us, the readers, witnesses.
