Roald and I go back to 1958 when I was an IBM 650 programmer at NIH and made some presentations at the SHARE meetings. One of the best compliments I have ever received was when he introduced himself to me, saying that we ought to get together because I was in his league. We have corresponded off and on over the years and played tennis a few times but I don't think we had seen each other since Princeton played in the eastern regionals in Raleigh. He shared my enthusiasm for tennis and college basketball. Roald is a great loss.
