I recall the first time I met and experienced Bill. It was at a design conference, and his entry marked the moment I branded him as “the Obi-Wan Kenobi of the design world.” There was a grace and purpose to his presence that I’ve never experienced in anyone else. Many years later I was fortunate enough to become an IDEO employee, and saw the same energy and spirit remained in Bill. He will be missed so greatly, but his legacy of work and passion will survive always in our hearts and minds.
