A New Book Says A Jewish Notary Was Behind The Betrayal Of Holocaust Victim Anne Frank, CNN reports

In Anne Frank’s Betrayal, author Rosemary Sullivan tells the story of a team of researchers determined to find out who revealed the Amsterdam hiding place of the Frank family and several others. They were discovered and arrested, and Anne eventually died in a concentration camp when she was 15.

Anne’s diary was later published as: A young girl’s diary† it has become one of the most enduring literary works of the 20th century.

The research team of historians and criminologists concluded that Arnold van den Bergh, a Dutch notary and member of the Amsterdam Jewish Council, probably informed the Nazis where Jews were hiding in the city to protect his own family.

An anonymous person sent Anne’s father, Otto Frank, a note stating that Van den Bergh was behind the betrayal. Pieter Van Twisk, a journalist who worked in the investigative team, said Otto Frank was aware of the note.

In a rating from Sullivan’s book in the New York Timescritic Alexandra Jacobs writes that “the argument advanced by the researchers for Van den Bergh’s guilt is convincing, if not convincing.”

Anne Frank’s Betrayal was published Tuesday by Harper.
