Five-time Nebula winner Greg Bear died November 19, a week after heart surgery from which he never awoke. A CT scan showed stroke damage was caused to many parts of the brain by clots that had been hiding in a false lumen of the anterior artery to the brain ever since an earlier surgery eight years ago. After a review of the possible outcomes by the medical team, and following the wishes expressed in his advance directive, Bear was taken off life support and died two hours later.
He wasn’t a major talent or a SF icon, but he was a legitimate author who represented the last gasp of mainstream science fiction being founded in actual science. I didn’t know him, and I didn’t particularly like the three or four books of his that I read, but his passing is indicative of an era that is observably in the process of ending.
