David Kelley, founder and CEO of IDEO Product Development, grew up in Ohio, where he survived on a diet of Velveeta cheese and white bread, He attended Carnegie Mellon and studied electrical engineering, but spent more time working on carnival floats. After graduation, he worked for Boeing on the 747. He learned early that in a large company, he didn't get to choose the people he worked with. He came to the Graduate Product Design Program...more
