Pulitzer Prize winner Alfred D. Chandler Jr., 88, the Harvard Business School professor who developed the field of business history with his works that examined the management factors that drove the American economy, has died.

He died May 9 of cardiac arrest at Youville Hospital in Cambridge, Mass.

His books examining management theories and practices influenced scholars across disciplines, including history, economics, sociology and management science.

He won the 1978 Pulitzer in history for The Visible Hand: The Managerial Revolution in American Business, in which he wrote that the "visible hand" of management had replaced the "invisible hand" of market forces in shaping business.

He wrote books on major U.S. corporations and helped former General Motors chairman Alfred Sloan write his memoirs. He continued to write late into life, publishing a book in 2005 examining the impact of pharmaceutical companies on the economy.

At the time of his death, he was writing a biography of his grandfather, Maj. William G. Ramsay, the first chief engineer of the DuPont Co.

He taught at the Massachusetts Institute of Technology and Johns Hopkins University before joining the Harvard Business School faculty in 1970. - AP
