Sam Zell, Jewish billionaire whose media purchase tarnished a legendary career, dies at 81
Before buying the Tribune Co. in 2007, the billionaire was known for his gift for reviving moribund companies. He developed an office-tower company that he sold to the Blackstone Group for $39 billion in 2007. His firm also invested in manufacturing, travel, retail, healthcare and energy. He pioneered the use of REITs, real estate securities that trade like stocks on the major exchanges.
