Chairman, Tata Group
As head of one of India's most venerated family businesses, Tata, 69, has unique stature. The Tata Group, which is one of India's largest conglomerates, includes India's largest software house, one of its most prestigious hotel chains (the Taj), and sprawling steelmaking operations, as well as leading players in consulting, wireless, and cable services. Since taking over in 1991, Tata has made numerous big-ticket deals. But his heart is set on a project closer to home: creating a $2,500 car that middle-class Indians can buy. --Clay Chandler
