Raoul Wallenberg
The Swedish government sent Wallenberg to serve as a diplomat in Budapest, Hungary's capital.  He gave Swedish passports to about 20,000 Jews, allowing them to ask for the protection of the neutral Swedish government.  He also protected Jews in houses he bought or rented with his own money or money from the groups that had sent him.  Wallenberg, a Lutheran, was assisted by Roman Catholic and other non-Jewish leaders.
