Bermudian insurance stalwart Brian Duperreault has been ranked as the eighth most influential industry player in the past 30 years by Reactions magazine.The global re/insurance trade journal marked its 30th anniversary by publishing a top 30 list of insurance executives over the last 30 years.Mr Duperreault, who was inducted into the Insurance Hall of Fame earlier this year, is president and CEO of Marsh & McLennan Cos Inc and former CEO of Ace Ltd.“Bermuda-born Brian Duperreault had a large role to play in transforming the island of his birth into a global insurance centre,” said the publication.“During his time as chairman and CEO of Ace Limited from 1994 to 2004, he embarked on an ambitious quest for expansion, including the brave purchase of Cigna P&C, which cemented Ace as a truly international insurance and reinsurance powerhouse. He was formerly CEO of AIG’s American International Underwriters.“Duperreault retired as Ace’s chairman in 2007, but was not done there. He took over as president and CEO of Marsh & McLennan Companies in January 2008, and embarked on a plan to restore the firm’s reputation and performance following some tough years following Eliot Spitzer uncovering evidence of bid-rigging at its broking unit, Marsh, in 2004. To the surprise of no one, Duperreault succeeded in quickly getting the firm back on its feet.”
