A daughter discovers her father’s secret past and shares his story with the world.

Andrew Burian survived both the Birkenau and Mauthausen concentration camps as well as the infamous death march evacuations of each camp. Today, he uses the lessons of his childhood as a catalyst to fuel his lasting dedication to Holocaust education and remembrance.

Holocaust survivor Leon Leyson passed away this January, but his story of survival as the youngest boy on Oskar Schindler’s “list” will live on in his new memoir, The Boy on the Wooden Box: How the Impossible Became Possible…on Schindler’s List, which was officially released today.
