'Magda Hellinger was deported to Auschwitz on the second transport from Slovakia in March 1942, at the age of twenty-five. She was one of the very few to survive over three years in concentration camps. During her time in Auschwitz-Birkenau she held various prisoner functionary positions and had direct dealings with prominent SS personnel, using her unique position to save hundreds of lives.'
