Biography
Macomber was a senior partner at McKinsey & Co. until 1973 and chairman and CEO of Celanese Corporation from 1973 until 1986. He exited when the company was acquired by Hoechst AG to become the largest chemical company. Celanese had been ahead of its time in stock buybacks, and Macomber was especially proud that 20% of company stock was "owned by middle managers and ordinary folk who are extraordinarily well off". During the 13 years he led the company, the stock increased in value by 10 times, from $24.50 to $245.

Macomber is also chairman of the Council for Excellence in Government, Rand McNally and Company, and vice chairman of the Atlantic Council. He has retired from serving on the board of directors of Lehman Brothers, Bristol-Myers Squibb Company, The Brown Group, Inc., Chase Manhattan Bank, RJR Nabisco, Pilkington Ltd., and Xerox Corporation. In addition, Macomber served on the Lincoln Center board and the International Chamber of Commerce.
