Sad, but the man had a busy and productive life which he made the most of.
Julius Schwartz was famous for being written into the comics several times. The Ambush Bug special noted above was probably the last time (I think), but his Earth-Prime counterpart appeared in some early 1970s issues of THE FLASH and JUSTICE LEAGUE OF AMERICA and met some of the "fictional" characters which he edited. Later, in the mid-1980s a special issue of SUPERMAN was created in which the Earth-1 Julius Schwartz, an out-of-work homeless guy, meets up with Superman and eventually meets his Earth-Prime counterpart as well. It turns out in that story that the E-1 Schwartz had come up with the ideas for Superman, Batman, Wonder Woman, and the Flash (under different names) before they ever appeared in public on Earth-1, and the real-life superheroes ended up causing his fictional creations to sell poorly, eventually leaving him without a job. It was a special 75th birthday (I think) issue of SUPERMAN which was done behind his back and without his knowledge in order to surprise him. It was quite cool, and it is hard to imagine a modern counterpart to Julius Schwartz. Longtime Super-books editor Mike Carlin is as hated as he is loved, and though Denny O'Neil has the history as an editor and writer for the Bat-books, among others, he is not Julius Schwartz.
Julius Schwartz was probably the one man most responsible for ushering in the "Silver Age of comics" with his revamping of the classic golden age characters the Flash, Green Lantern, the Atom, Hawkman, and especially the Justice League of America, an updated version of the old Justice Society of America. Stan Lee would likely have long ago quit comics altogether had it not been for Julius Schwartz's bringing back the super-hero as a popular genre. All the modern writers, artists, and editors are standing in his shadow, and all of us as comics fans owe Julie a debt of gratitude.
