In one of our early meetings about setting up W3C with a base at MIT, I was concerned that the organization should not just be US based, but be global. I expressed this to Michael and he gave me one of his big, slightly shoulder-crushing, one-arm hugs as we walked along. I realized later that he had spent a lot of his life trying to link across the Atlantic, so this was music to his ears.
Virtual meetings could never be the same as physical meetings, he used to say, because of the effect of the cave, that when you are in a small space with someone, you know subconsciously they could hurt you, which changed the dynamic completely. He would use that shoulder squeeze to emphasize the point.
On stage at the World Economic Forum plenary at Davos one year, he and Bill Gates were on stage together, and Bill must have suggested too much faith in virtual meetings. Michael leaned across and wrapped an arm around Bill, gave him that squeeze. From my seat in the audience, I guessed Bill got the point.
It was great to work in Michael's lab as he had very little sense of the impossible. He was also very supportive, personally, of lab members, checking discretely on home and family as well as work. A very human person, then, large in person, but larger in overflowing human spirit.
