Lise Gimpel was the wife of Heinrich Gimpel, the sister of Käthe Franks, and the mother of Alicia, Francesca, and Roxane. Like her husband, Lise was also a Jew. Her parents were killed by a drunk driver a few years before Alicia's tenth birthday. Although Lise engaged attorney Klaus Menzel and Erika retracted her statement, Heinrich and the girls were released through the covert aid of another, previously unknown secret Jew who held the rank of major in the Security Police. In 2011, Lise and her family told the secret to her second daughter, Francesca.
