Denis Dutton, who founded and edited the website aldaily.com, passed away on 28 December 2010. Dutton was born in 1944, and was also a professor of philosophy at the University of Canterbury, New Zealand. He was a founding member of the New Zealand Skeptics. Although Dutton is "nearly irreplaceable" in running Arts & Letters Daily, a longtime collaborator will continue to produce the site.
