Clarke, Asimov, Heinlein, now Bradbury. Who’s left? Frederick Pohl ... But he must be 100 by now. Even Lester Del Ray and Andre Norton are gone.
Dim hopes for sci fi’s future.
Frederik Pohl is 92, Jack Vance is 95. There is a very recent interview with both of them interacting together on star ship sofa I believe. Vance is still mad that Pohl edited his intros to the chapters of Demon Princes! Pretty funny. Poul Anderson and Frank Herbert are both gone.
Freegards
I'm guessing about ninety-plus. Had a nice email chat with him about 3 years ago, where the subject was symphony orchestras. I found out that he had attended my hometown symphony, and I clued him in to a recording they had recently released.
He's married to a younger woman who is (or was a few years ago) a professor of, IIRC, English at a suburban Chicago college.
