Georges-André Kohn was born in Paris on April 23, 1932. He had three brothers and sisters. His father Armand Kohn was a physician and director of the hospital »Baron de Rothschild«, the largest Jewish hospital in Paris. The Kohn family was of the Roman Catholic faith. But in 1940, when the Germans invaded and occupied France, Nazi thinking suddenly declared them to be Jews because they had Jewish ancestry. They were thus rendered defenseless victims exposed to persecution by the Nazi occupiers.
