Number 25: Executive branchAlfred P. Sloan Jr., the chief executive of General Motors Co., had a problem. He saw many promising would-be executives in his company but didnt know how to train them. So in the early 1930s, he came to MIT, his alma mater, and asked for help. MIT accepted the challenge and devised an experiment in executive education, inviting a small group of fellows from various companies to spend an intensive year of business and leadership training on campus. Now called the MIT Sloan Fellows Program in Innovation and Global Leadership, it has been copied elsewhere and many of its most famous graduates are on this list for their achievements in business.
