Poul Anderson died last night
Just found this on the Jerry Pournelle website, posted today, August 1:
Poul Anderson, mentor, author, colleague, and friend, died last night about midnight. It wasn't unexpected. He was at home with his wife and daughter and friends, having long ago declined to be frozen and possibly take part in the nitrogen party at the end of time. I will be doing a memorial piece for Locus and other science fiction publications. We don't do Viking funerals any more. We should.
