From the web site companion to the incredible Designing Interactions book.
In 1978 Bill was a graduate student in neuroscience at the University of Washington when he got a call from Apple, suggesting that he visit. Steve Jobs persuaded him to join, saying, “If you want to make a dent in the world, you have to come to the place where it’s happening!” He was hired as the “Application Software Department,” and went on to lead the development of the software for Lisa and Macintosh, and to design MacPaint and HyperCard. He was a leader and inspirational designer at Apple for twelve years, during which time Apple grew from thirty people to fifteen thousand. Bill Atkinson designed several of the interactions that define the desktop.
Atkinson's current focus: Numenta.
