Robert Killheffer has been an editor, critic, and reviewer in the SF/F world (and occasionally beyond) for more than three decades. He began his career as editorial assistant to Ellen Datlow at OMNI and as an early member of the staff of The New York Review of Science Fiction. Later he edited the literary magazine Century, launched the webzine Event Horizon (with Ellen Datlow and others), and wrote a book review column for Fantasy & Science Fiction magazine for about a decade. More recently he has contributed entries and updates to the online Science Fiction Encyclopedia and was an editor of the all-too-short-lived revival of OMNI.
