Gupta is chairman, president and CEO of the international chemical giant Rohm and Haas--the first Indo-American to lead a Fortune 500 company. Daughter Vanita is a crusading human-rights lawyer with the American Civil Liberties Union--a stereotype-defying career choice supported by her father and mother, Kamla.
