Laureen Nussbaum (born Hannelore Klein, August 3, 1927)[2] is a German-born American scholar and writer.

After retirement Nussbaum now lectures on the Holocaust, Anne Frank and her experience during World War II.

[10] While clear that "Otto should be congratulated for probably being the first to publish a document from the Holocaust," she has criticized him for combining Anne's two versions of her diary into one without explanation.

However, when the Nazis invaded the Netherlands in 1940, Jews were barred from many public places and in 1942 were forced to wear yellow stars on their clothing to denote their ethnicity.

After that claim was accepted by the German authorities, only Nussbaum's father had to wear the yellow star on his clothing.

This is the subject of her book Shedding Our Stars: The Story of Hans Calmeyer and How He Saved Thousands of Families Like Mine published in 2019.

Rudi hid for four years before the war ended, at first living with Dutch peasants, then in the countryside, and finally in the Klein home.
