Number Nine: BoseMIT electrical engineering professor Amar Bose had a simple mission in 1964: design a stereo speaker that could come closer to reproducing the sound of a live musical performance. His company led the rush to create dozens of game-changing products, from noise-canceling headphones to a better bedside alarm clock. Its newest product is a flat-panel TV that eliminates the need for external speakers. Bose donated most of his stock to MIT last month making MIT the companys majority owner. Bose has more than $1.8 billion in annual revenues and about 8,000 employees.
