An author of a new book is defending the controversial legacy of a man who saved thousands of lives in the Holocaust.

“Kazstner’s Train: The True Story of Rezsö Kasztner, Unknown Hero of the Holocaust'” focuses on the efforts of Rezsö Kasztner, a Hungarian Jew who managed to negotiate the escape of Jews from the Nazis.

One of the most visible example of his efforts was the transportation of almost 1,700 Jews to Switzerland on what was dubbed “Kasztner’s Train.”

According to the book’s author, retired publisher Anna Porter, Kasztner also saved another 12,000 to 18,000 lives.
