As Denmark became occupied by the Germans, Danish individuals rowed and motored boats full of Jewish refugees to neutral Sweden and saved their lives, often risking their own. In France, hundreds of families opened their homes to take in Jewish children as their own to save them. One lone Polish man hid 20 Jews in his city’s sewer system, and he and others kept them alive with clothing, blankets, food and drink until the Russians occupied Poland. French resistance fighters rounded up dozens of Jews and led them safely into neutral Switzerland. At the top of the list of rescuers was Raoul Wallenberg, a Swede who headed his country’s embassy in Hungary, who actually saved thousands of Jews by issuing false passports, provided clothing, food and supplies and enabled them to reach safety. There were thousands of individual heroes in various countries, simple people, from company executives to factory workers, farmers, policemen, housewives, etc., who put their personal safety on the line to save Jewish friends.
