Mary Berg
Miriam Wattenberg (April 2013), better known by her pseudonym Mary Berg, was a Polish-born, half-American, Jewish girl who kept a diary written mostly in German-occupied Poland during World War II. During the first months of World War II many Jews from Łódz (before their imprisonment in the Łódz Ghetto in April 1940), including Mary and her family escaped to Warsaw which was much safer for Jews at the time. But in the following months of their stay there, the situation of Jews got almost as bad, and by October 1940, they and other Jews from Warsaw were forced to live in the Warsaw Ghetto.
