Old Time Science Fiction writers. Robert A. Heinlein.

   Heinlein has been dead for nearly 35 years now.  I remember seeing his obituary on the front page of the Boston Globe back in 1988.  The only other writer to ever get a front page obit in the Globe was Tolkien back in the 1970s.  To get a front page obit you have to be very widely read and your writing must be considered important.  In a long active career Heinlein wrote a lot of stuff, all of it good reading.  Some of his best were Have Spacesuit Will Travel, The Moon is a Harsh Mistress, Red Planet, and The Star Beast.  And a lot of others, all well worth reading.  Controversial is his novel Stranger in a Strange Land.  This book drops out of the hard science fiction mold into something else that is hard to describe.  It works best for older readers, into (or graduated from) high school.  I would discourage children from, reading it while they are still in grade school.
