Business historian Tedlow (Harvard Business Sch.) presents seven magnates in a historical context that reflects the growth of the United States as an economic power from the mid-1800s to the latter part of the 20th century. Presenting biographical essays divided chronologically into three sections, he first discusses Andrew Carnegie (U.S. Steel), George Eastman (Kodak), and Henry Ford (automobiles) and their contributions to the emergence of America as an economic force. The founding of IBM by Thomas Watson Sr. in 1924 and Revlon by Charles Revson in 1932 are then used to highlight technological leadership and marketing, respectively. The leadership, management, and determination of Robert Noyce (Intel) and Sam Walton (WalMart) demonstrate the success of entrepreneurs in recent times. Each essay concerns the central figure and his contribution, personal attributes and faults, family, close associates, and a history of the specific industry and American society at the time. — Copyright 2001 Reed Business Information, Inc.
