R.I.P, Julius Schwartz

From Ansible 200, March 2004: "Julius Schwartz (1915-2004), US fan, literary agent, influential comics editor, and in later life a DC Comics consultant and `goodwill ambassador' to conventions, died on 8 February aged 88. With Mort Weisinger he coedited what many regard as the first true sf fanzine, The Time Traveller (1932); his and Weisinger's agency Solar Sales Service was the first to specialize in sf. "

I knew Schwartz as an important, influential comic book editor; I hadn't heard of his unique importance in sf fandom.
