Thomas F. Frist Jr.
70


How'd he get so rich? Along with his father, Thomas Frist Sr., he was co-founder of privately held Hospital Corp. of America. The former flight surgeon built HCA into the nation's largest for-profit hospital management company by agglomerating hospitals across the country to take advantages of economies of scale. In 1994, HCA merged with Columbia Healthcare to form the world's largest hospital company. Frist has a net worth estimated at $1.7 billion.
