Rando Bertoia was the last remaining person in Scotland to have escaped the sinking of the Arandora Star in 1940 by a German U-boat off Ireland.
His family said that the retired watchmaker, who lived in the Gorbals, suffered a heart attack on Saturday.
As a young man he had been put aboard the Arandora Star along with hundreds of Italians and Germans who had been living in Britain but were detained by the authorities on the outbreak of hostilities and were being exiled to Canada.
The tragedy remains almost forgotten, as it came early in the war and was a painful reminder of both the British Government's detention of potentially innocent people and the Italian state's aggression in Europe.
Mr Bertoia lost a cousin in the sinking.
A memorial to the disaster, the Italian Cloister Garden, has now been built next to St Andrew's Cathedral in Glasgow.
Mr Bertoia, who was born in Italy, spent the rest of the war in Australia before returning to Scotland.
Ronnie Convery, director of communications for the Archdiocese of Glasgow and Secretary of the Coordinating Committee for Italian Scots Associations, said: "I expecting him to be full of aggression and thoughts of revenge for what had happened to him, but he was utterly without any sense of injustice."
