Entrepreneur Roberto Colaninno, chairman and CEO of scooter maker Piaggio and one of Italy's best-known dealmakers, has died, his investment company IMMSI said on Saturday. Colaninno was a central figure in the country's industrial landscape who managed to turn around a number of failing companies, but also left a mixed corporate legacy. He is most famous for his surprise $58 billion leveraged buyout of Telecom Italia in 1999, at the time the world's largest hostile takeover.
