Hans (Juan) Deutsch was born in 1924 in Köszeg (Hungary). His mother came originally from Großpetersdorf. His father was the owner of an import-export grain business, founded by his grandfather. Hans Deutsch visited the Benedictine grammar school in Köszeg, where he did his A-levels in 1942. Between 1942 and 1944 he was an industrial worker. Early in 1944 he was enlisted for the labour force. His parents and his sister were arrested and deported in 1944, after the German troops marched in. In the same year he had to work under inhumane conditions on the Südostwallbau (building of the south-east ramparts during the end of WW II) in Hannersdorf, Burgenland. He survived the following death-march of Hungarian Jews and forced labourers over the "Präbichl" in Styria, and was sent to the concentration camp in Gunskirchen, Upper Austria. Freed by American troops on the 5th of May 1945, he went back to Köszeg, where he learned that his parents and sister had been murdered in Auschwitz. Only 9 out of 110 Köszeg Jews survived the holocaust, and of 9 members of the Deutsch family, Hans was the only one to survive. Hans Deutsch went to Zurich and studied for 4 years at the ETH of Zurich for electro-technology where he was trained as an electrical engineer. It was in Switzerland that he got to know his future wife. Following in his uncle's footsteps, Hans Deutsch emigrated to Buenos Aires and founded a firm for special technical measuring equipment. He has never been back to Köszeg since 1946. Hans Deutsch died in 2004 in Buenos Aires.
