György was barely 14 years old when on 5 July 1944 he was deported from his home in Bercsényi Street, Kaposvár, to the concentration camp in the artillery barracks and then to Auschwitz-Birkenau. During the selection process, he lied about being a year older than he was and a lathes apprentice, thus avoiding the gas chamber. In mid-July he was transferred to the Buchenwald concentration camp. In the Magdeburg-Rothensee subcamp he was forced to work in the Brabag fuel factory. It is known that he was hospitalized with some kind of childhood illness (Kinderkrankheit). His further fate is unknown. What is certain is that two-thirds of the prisoners in the camp died. His father, 45-year-old Sándor Walder, was deported to Dachau on 11 November 1944. He died there on 2 March 1945.
