The Boy on the Wooden Box is the only memoir written by a former Schindler’s list child. Leon was just ten years old when the Nazis invaded Poland and his family was forced into the Krakow ghetto. Luckily his father convinced Oskar Schindler to let Leon and other family members work in Schindler’s factory. Leon was so small he had to stand on a box to work the machinery. Later, he was No. 289 on the famous Schindler’s list. He rarely spoke about his experience until Steven Spielberg released his movie, then spent many years speaking to groups and eventually writing this book.
