Here's a link to the New York Times obit for Julie Schwartz. (One minor quibble: The 1956 Flash revival started with scripts by Robert Kanigher, not Gardner Fox.)
Also, there's an obit in Newsday and one in the Telegraph.
Also: Since folks are still writing to ask, I want to repeat: Donations can be made to the Julius Schwartz Scholarship Fund c/o DC Comics, 1700 Broadway, New York, NY, 10019.
