I am so sorry to hear that Richard has passed away. I was a Ph.D. student in Organizational Behavior at Yale when he taught there, and I feel very fortunate to have been a student in his class on high performing teams. As others have said, he often taught without his shoes on. He would get so excited about the topics he was teaching that every now and then he'd walk into a wall. One day we came into the classroom and someone had pinned pillows on each of the walls so that he wouldn't hurt himself when he walked into a wall. A joke, of course, but one that says a lot about his passion for learning and teaching about teams. To this day (twenty-five years or so later), I continue to use his goals-design-coaching model for creating high performing teams when I teach about high performing teams, and that model is universally useful. Richard was a thoughtful and enthusiastic professor who was also generous in making his ideas and resources available to others. My sympathies go out to his loved ones.
