Elsa Katz
Elsie "Elsa" Katz (born Elsie Taussig; ) was a Czech-born Jewish woman who kept a diary documenting daily life of inmates in the Theresienstadt Ghetto during World War II. She began writing the diary in 1943 after her eldest daughter Eva died from disease in the ghetto. The diary is written in 1943 and 1944. The diary was first discovered in August 1944 (the same month she died), by Elsa's daughter Vera in her mother Elsa's bed. After the war ended, Vera made her mother's diary available for publication.
