However, when her diary appeared in a book, it was revealed in 2008 that she was not sent to the gas chambers along with them.
Rutka was deported from the ghetto and was believed to have died in a gas chamber, age 14, along with her mother and brother, upon arrival with her family at the Auschwitz concentration camp in August 1943. Laskier's family was forced to move to the newly formed Jewish Ghetto in Będzin during the Holocaust in World War II. Her diary remained in the hands of Rutka's surviving friend for 64 years and was not released to the public until 2005. Following the German invasion of Poland, while in the Będzin Ghetto, Rutka Laskier, age 14, wrote a 60-page diary in Polish, chronicling several months of her life under the Nazi rule in 1943. Rutka moved with her family to the southern Polish city of Będzin, from whence her paternal grandparents hailed.
