He was 62 years old -- ironically, and chillingly, the same age as my father. I've known of Bob's work for years, but I actually didn't meet him until I joined the Boogie Knights, of which Bob has been a longtime fan. He and I also were part of an excellent panel at Dragon*Con last year on the use of violence in fiction. (Ironically, Bob is the second person on that panel to have died since -- the other being Hank Reinhardt. Equally ironically, Bob was going to be GoH at Marcon this weekend, an honor I received this time last year. Good thing I don't believe in omens....)
Bob was one of the finer ones we had, and his wit and smile and sick sense of humor will be deeply missed.
