I was in grad school with Greg at the UofI. Yes, he was a brilliant student. He also had a sense of humor and zest for life that wouldn't quit. He was an avid reader. And a musician - drummer in a band as I recall. And a vet, who survived having been in the service during the Viet Nam era. Greg was one of the treats of our social circle during that time. We went separate ways after school, and I haven't seen him in decades. I find it interesting that tonight, two days after his passing, from out of the blue I thought to search for him online. Greg, hope you're having a grand time hanging out in the afterlife. I'll always treasure my memories of our times together.
