I remember Leonard in Pittsburgh, PA, when we had the most wonderful group of friends I have ever had through the CMU Computer Science Department. Leonard and Jan were together then and it was always so much fun to go to their place for an evening. Leonard was fun, with the same twinkle in his eye that he had in that 8/26/02 photo. He had more hair, of course. I am sure that warm sense of humanity and friendship that he left in my memory has been experienced by many of his friends since. It is a great sense of loss to think he is gone. Linda M. Johnson, MD, PhD (former wife of Rick Gumpertz)
