Papers for a young man named Sandor Kiss "who had been born into a Hungarian family in Romania and who had made his way to Hungary after the war stated" were given to Soros.
During that time, Soros accompanied Baumbach as he took inventory of a wealthy Jewish aristocrat, Mor Kornfeld. The book says that Soros was not involved in the confiscation of property: "Baumbach was ordered to go to the Kornfeld estate and inventory the artworks, furnishings, and other property. Rather than leave his 'godson' behind in Budapest for three days, he took the boy with him.
"As Baumbach itemized the material, George walked around the grounds and spent time with Kornfeld's staff. It was his first visit to such a mansion, and the first time he rode a horse. He collaborated with no one and he paid attention to what he understood to be his primary responsibility: making sure that no one doubted that he was Sandor Kiss."
