It's being reported that Jack Williamson, one of the living legends of the field, has just died. Williamson was the second writer to be named a Grand Master by SFWA, in 1976, and was a working SF/Fantasy/Horror writer from 1928 through the present day -- a 78-year career that will probably never be equalled. His most famous works include the chilling SF novella "With Folded Hands" and the formative dark fantasy novel Darker Than You Think.
