Raoul Wallenberg, a Swedish diplomat, saved thousands of Hungarian Jews from the Nazis during World War Two.

Once Soviet troops reached Budapest, Wallenberg reported to Soviet officials on 17 January 1945. But he was never seen in public again. Rumours of his fate have circled ever since: a Soviet government report said he died of a heart attack in prison, while former officials said he was executed, and prisoners claimed to have seen him decades later. There is still a campaign to uncover what happened to him.
