Montreal-born Bronfman took control of the Seagram empire from his father, Samuel Bronfman who had founded the liquor company in 1924. He then expanded its operations, acquiring Tropicana, moving Seagram into oil business and even chemicals, by making it DuPont's largest minority shareholder.
The son of Eastern European Jewish immigrants was president of the World Jewish Congress from 1981 until 2007, presiding over its transformation into a more focused and confrontational organisation.
During his tenure, the US Congress increased pressure on the then-Soviet Union to loosen emigration restrictions on Jews living there. Bronfman also pressed Congress' efforts to expose the Nazi past of former UN secretary-general and later president of Austria, Kurt Waldheim.
The WJC during that period also joined the effort to force Swiss banks to make restitution of more than $1 billion to relatives of German death camp victims who deposited funds in n Switzerland before World War 2, the Times said.
What we have to do is write the last chapter, Bronfman told Reuters in a 1996 interview to promote his book, The Making of a Jew.
We will get the story, there is no question of that, he said. But in the meantime, Holocaust survivors are dying every day.
Bronfman, who published his memoirs Good Spirits: The Making of a Businessman in 1998, one of four autobiographical books, was put in control of Seagram's US subsidiary, Joseph E Seagram & Sons, by his father in 1953. He became a US citizen a few years later, the Times said.
