I'd heard similar before as well.
"Soros was 13 years old in March 1944 when Nazi Germany occupied Hungary.[43] The Nazis barred Jewish children from attending school, and Soros and the other schoolchildren were made to report to the Judenrat ("Jewish Council"), which had been established during the occupation. Soros later described this time to writer Michael Lewis: "The Jewish Council asked the little kids to hand out the deportation notices. I was told to go to the Jewish Council. And there I was given these small slips of paper ... I took this piece of paper to my father. He instantly recognized it. This was a list of Hungarian Jewish lawyers. He said, 'You deliver the slips of paper and tell the people that if they report they will be deported'."[44][45]
Soros did not return to that job; his family survived the war by purchasing documents to say that they were Christians. Later that year at age 14, Soros posed as the Christian godson of an official of the collaborationist Hungarian government's Ministry of Agriculture, who himself had a Jewish wife in hiding. On one occasion, rather than leave the 14-year-old alone, the official took Soros with him while completing an inventory of a Jewish family's confiscated estate. Tivadar saved not only his immediate family but also many other Hungarian Jews, and Soros later wrote that 1944 had been "the happiest [year] of his life," for it had given him the opportunity to witness his father's heroism.[46][47] In 1945, Soros survived the Siege of Budapest, in which Soviet and German forces fought house-to-house through the city."
