A statue called the Serpent Slayer in honour of Raoul Wallenberg by Pál Pátzay stands in XIII Szent István Park. Of all the 'righteous gentiles' honoured by Jews around the world, the most revered is Raoul Wallenberg, the Swedish diplomat and businessman who rescued as many as 35,000 Hungarian Jews during WWII.
Wallenberg, who came from a long line of bankers and diplomats, began working in 1936 for a trading firm whose president was a Hungarian Jew. In July 1944 the Swedish Foreign Ministry, at the request of Jewish and refugee organisations in the USA, sent the 32-year-old Wallenberg on a rescue mission to Budapest as an attaché to the embassy there. By that time, almost half a million Jews in Hungary had been sent to Nazi death camps.
Wallenberg immediately began issuing Swedish safe-conduct passes (called 'Wallenberg passports') from the former Swedish embassy (Minerva utca 3a/b, on Gellért Hill), which bears a plaque attesting to the heroism of Wallenberg and the less well-known diplomats Carl-Ivan Danielsson (1880-1963) and Per Anger (1913-2002). He also set up a series of 'safe houses' flying the flag of Sweden and other neutral countries where Jews could seek asylum. He even followed German 'death marches' and deportation trains, distributing food and clothing and actually pulling some 500 people off the cars along the way.
When the Soviet army entered Budapest in January 1945, Wallenberg went to report to the authorities but in the wartime confusion was arrested for espionage and sent to Moscow. In the early 1950s, responding to reports that Wallenberg had been seen alive in a labour camp, the Soviet Union announced that he had in fact died of a heart attack in 1947. Several reports over the next two decades suggested Wallenberg was still alive, but none was ever confirmed. Many believe Wallenberg was executed by the Soviets, who suspected him of spying for the USA.
