Charles Sheffield Dies at 67; Physicist, Sci-Fi Author (washingtonpost.com)
Charles Sheffield‘s site is worth visiting, and contains a good bibliography and some nice bits of autobiography:
…I hated what I was finding; and after a while I had the dangerous thought, “You know, I could probably write something as bad as this myself.”
I tried. And soon I learned that I could not only produce something as bad as what I was reading, I could write something a good deal worse.
