Palatucci did die at Dachau, but was sent there after falling out with the Nazis in an unrelated dispute, not for protecting Jews, the research says. "There is an enormous contrast between the reality of what happened in Fiume during the war and the legend of Giovanni Palatucci," said Natalia Indrime, the centre's director.
Alexander Stille, a Columbia University journalism professor from an Italian Jewish family who has reviewed the centre's investigation, said Palatucci was the beneficiary of a "much-needed feel-good story in Italy after the war".
Yad Vashem, Israel's Holocaust memorial, said it was examining the findings. The institution named him "Righteous Among the Nations", one of the highest honours for non-Jews, in 1990. A Vatican source said Palatucci's possible beatification and canonisation was now under review.
Rolando Balugani, of the Giovanni Palatucci Association, said the report ignored dozens of witness statements by Jews who said he saved them.
