Nació: March 3, 1933
Zuzana was the youngest of three children born to Hungarian-speaking Jewish parents in the city of Kosice. She was the baby of the family, and they called her Zuzi. Her father was a tailor whose workshop was in the Gruenbergers' apartment.
1933-39: In November 1938, when Zuzana was 5, Hungarian troops marched into Kosice and made it a part of Hungary. The Hungarians changed the name of the city to Kassa. The Hungarian government was friendly to Nazi Germany and introduced anti-Jewish laws in Kosice.
1940-44: In 1941, one year after Zuzana began school, the Hungarians moved the Gruenbergers and other Jewish families to camps in other parts of Hungary. The Gruenbergers were released the following spring and returned to Kosice, but Zuzana's brother and father were taken soon after for slave labor. In 1944 Kosice's 12,000 Jews, including Zuzana, her mother and sister, were rounded up by Hungarians who were cooperating with the Germans. They were sent to a brickyard at the city's edge and put on trains headed for Auschwitz.
Zuzana and her mother were gassed immediately on arriving in Auschwitz in May 1944. Zuzana was 11 years old.
