Good ol' Rick. Doesn't look a lot older than he did in the late 70's. I don't think he ever got enough credit for masterminding the Lisp Machine development at the MIT AI Lab; it was really his baby from start, though there were several key people working on it with him (Moon, McMahon, Cannon, Knight, etc.) He's a humble fellow and one of the best.
