Jack Burnley died at the age of 95. Burnley was best known as the co-creator of Starman, but he also did some work on numerous other DC books, including a few Batman covers. In addition, he did the Golden Age Superman comic strip for a while. I'll confess that Burnley is one of the Golden Age creators whose work I appreciate on an intellectual and historical level, but not on the more visceral level at which I appreciate many of the others Golden Age creators. I was never an avid fan of his work, and I never had a chance to see him at any convention; nevertheless, I recognize that he was a contributor to the creation and success of a medium that I love, and thus his passing saddens me.
There are so very few of these pioneering talents left, so the loss of each one has an increasingly greater impact on the field as a whole. Stan Lee, Carmine Infantino, Murphy Anderson, and Joe Kubert are the last surviving major talents; let's hope that many years pass before I have to make note of their passing as well.
