Dr. Steve Ban is the son of Noemi Ban. She was a survivor of Auschwitz. 

Noémi Ban was born in Szeged, Hungary, in 1922.  She and her family were living in the town of Debrecen when the Nazis invaded Hungary in March 1944.  Gradually and systematically, the Nazis deprived Jews of their rights. Noémi's father was sent to serve in a labor battalion forced labor camp. Three months later, the Nazis forced Noémi, her mother, grandmother, sister, and baby brother into a cramped cattle car and deported them to Auschwitz-Birkenau.

Upon arriving at Auschwitz on July 1, 1944, Noémi was separated from her family.  

After suffering for months, Noémi and 1000 other women were taken to a sub-camp of Buchenwald in Germany called Allendorf. There, they worked as forced laborers at a munitions factory.

As the Allies approached in spring 1945, the Nazis forced the women on a death march. Noémi was one of 12 women who escaped into a nearby forest, where an American soldier serving under General Patton liberated them. After regaining her health, Noémi returned to Debrecen and reunited with her father, the only survivor of her family.
