Michael Swanwick just announced the death of Gardner Dozois on Facebook:
It is my sad duty to note the passing of Gardner Dozois today, Sunday May 27, at 4:00 p.m. The cause was an overwhelming systemic infection. Gardner had been hospitalized for a minor illness and was expected to be released shortly. The decline was swift. He died surrounded by his family.
Gardner was a swell guy, one of the funniest people in the field, a fine writer and a great editor, and bought not only my first story, but more of my stories than anyone else over the years.
I’m about to rush off somewhere, but more extensive thoughts later.
