Over the years, I had the honor of meeting Le Guin a few times, but I cannot claim to really have known her as a person. Our encounters, such as they were, were all at conventions or Nebula banquets or writer's workshops, and they were all brief and forgettable.
But I certainly knew her work... as anyone who calls themselves an SF fan surely must. She was one of the giants. A gifted storyteller, dedicated to her art, she influenced a whole generation of writers who came after her, including me. THE LEFT HAND OF DARKNESS ranks as one of the best science fiction novels ever written, in my estimation, and THE DISPOSSESSED and THE LATHE OF HEAVEN were splendid works as well. The original Earthsea trilogy occupies a similar lofty position in the fantasy pantheon (though it was badly served by its television adaptation).
The Golden Age of Science Fiction is usually reckoned to have been the Campbell Era at ASTOUNDING, and its Big Three were Heinlein, Asimov, and Van Vogt. Yet as important as that era was, for me the true Golden Age will always be the late 60s and early 70s, when the Big Three were Roger Zelazny, Samuel R. Delany, and Ursula K. Le Guin. We shall never see their like again.
The world is poorer today.
