Erez is Dina’s son in law and was honored to be the co-writer and editor of the book on her remarkable life story: “Dina - Surviving Undercover.”

Dina was born in 1924 in Koszyce, a small Polish town, to the Jewish Lowenstein and Minzberg families. She survived WWII with fake identity papers, which allowed her to pretend to be a Polish girl. Her life story could be an excellent thriller made up by someone’s wildest imagination, but there is nothing fictional about it – it is all real and full of real truths.

Dina was smuggled out by the Polish underground just days before the entire Jewish population in Koszyce was annihilated. She survived three months of bombing by the Nazi and Soviet armies and was then captured by the SS and sent to a slave labor camp in Germany. After the war, Dina met Bezalel Drori. Dina and Bezalel were captured by the British as illegal immigrants, expelled to a detention camp, and took part in the bombing of a British deportation ship on their way back to Israel.

Dina and Bezalel lived in Israel and raised two children: Nimrod and Hana.

On January 25, 1968, Nimrod was declared missing on the lost submarine, Dakar, together with 69 sailors.

Dina is 93 years old today. She is a grandmother to Nimrod, a well-known Opera Singer, the son of Hana, who is married to Erez, and great-grandmother to Mey-Or, the daughter of Nimrod and Gali.

Throughout her intense life journey Dina never ever gave up. She never became morbid or revengeful. Dina became a life mentor for many of the people around her, because of the wisdom, integrity, and forbearance that she gathered against all impossibilities.
