Past guests of honor have included authors such as Greer Gilman, Gene Wolfe, Octavia Butler, Samuel R. Delany, Karen Joy Fowler, Brian Aldiss, Nalo Hopkinson, Joe Haldeman, Caitlín R. Kiernan, Peter Straub, and China Miéville, and editors such as Ellen Datlow and David G. Hartwell.  The convention also makes a point of honoring a deceased author as the Memorial Guest of Honor.  In 2009, for instance, the guests of honor were the living writers Elizabeth Hand and Greer Gilman and the memorial guest of honor was Hope Mirrlees.
