Robert Benmosche, who took the helm of insurer American International Group (AIG.N) after a massive government bailout at the height of the financial crisis, died on Friday at 70 after a battle with lung cancer. Benmosche is credited with steering AIG through the turbulent period following its near collapse and rescue by the U.S. government. During his tenure, which started in August 2009, AIG fully repaid the $182.3 billion government bailout it received in 2008 to stave off bankruptcy.
