Fantasy & Science fiction author L. Sprague de Camp died early this
morning after an extended illness.  He had been hospitalized for a week.
 His wife Catherine Crook de Camp died in April.  They had been born in
the same year as well.

Old time readers may remember that de Camp and Fletcher Pratt
collaborated on the Harold Shea stories, also kown as "The Incompleat
Enchanter" (and later "The Compleat Enchanter") series, beginning with
"The Mathematics of Magic" wherein the hero discovered that by altering
his perception of the universe's laws, he would slip into a parallel
universe where magic of some form worked - and in the course of a half
dozen adventures, he found himself in several of earth's mythologies.
