A Hungarian Jewish community leader who collaborated with Eichmann and other S.S. officials to save prominent Jews—ultimately by paying a price for each head—and secure their passage to Palestine. After the war, Kastner moved to Israel, where his work with Nazis led to a public controversy and then a libel trial against his critics, which he lost; he was assassinated in 1957, before the court posthumously overturned its judgment on his trial in 1958.
