Only in reading the February Ansible did I learn that artist GAK died mid-January. His real name was evidently Gregg Kanefsky (edited to add: probably not; that seems to be a different GAK), though I also knew him as Glenn Denny Gak (the name he used on Facebook), and an obituary linked from his Facebook page referenced Glenn A.
