F. Kenneth Iverson
F. Kenneth Iverson (September 18, 1925 – April 14, 2002) is credited with transforming Nucor Steel from a nearly bankrupt company in the 1960s into the largest and most successful steelmaker in the United States. Trained as a metallurgist, he became a very successful leader and businessman. His management philosophy has been used as a model for other companies around the world.
Management philosophy 
Iverson vigorously advocated a lean management staff, decentralized decision-making structure, and egalitarian work environment. At Nucor, he brought the number of levels of management down to 4 - a janitor was literally four promotions away from the CEO's job. Furthermore, he located the corporate headquarters far away from any production facilities and gave each mill great leeway in its own marketing and production decisions. Under his leadership, Nucor did away with executive perks such as reserved parking spaces and special health benefits, and Iverson is known to have personally answered his own phone whenever he was in the corporate office- where a staff of 22 was sufficient for managing the entire multibillion dollar corporation.
Achievements and Awards 
Iverson was inducted into the inaugural class of the American Metal Market Steel Hall of Fame (http://www.amm.com/HOF-Profile/KenIverson.html) for his work that revolutionized the dynamics of steel production in the 20th Century as fully as Sir Henry Bessemer had done in the 19th Century.
