Leon Rajninger is a youthful 82-year-old grandfather, gifted with longevity after losing most of his childhood to Nazi persecution in his native Romania. Mindful that the number of eye witnesses to this tragedy is steadily diminishing, he wrote the book 'Black Days and Black Nights' to tell his story to a generation of children and young adults who may never have heard the words, The Holocaust.

Leon has appeared as a Survivor on the floor of the California State Assembly and told this story at The Law School at USF and to students at high schools in San Francisco where he lives with his wife, Eva, and visits often with his loving children and grandchildren
