Carl Smith also played an important role in the computational complexity community. He organized conferences in the early 80's at Perdue and Maryland on Recursion Theoretic Aspects of Computer Science, precursors to the current IEEE Conference on Computational Complexity. He also co-organized the third Complexity (then called Structures) conference in Georgetown in 1988.
Carl was a colleague and a good friend. We both had sabbaticals in Amsterdam in 1996-7, wrote some papers together and often visited each other afterwards. We shared a love of beer and baseball; I would plan my trips to Maryland around the Orioles home schedule.
I always enjoyed the time I spent with Carl and the many interesting discussions we've had. I, my family, and the entire theory community will miss him greatly.
