Death of John M. Stewart

I regret to tell readers that Dr. John M. Stewart of the University of Cambridge passed away on November 14th after a short illness following a collapse on November 8th. The funeral will be on November 30th. John and I shared an office as graduate students but I will not write more about his career as there is a full obituary at http://www.kings.cam.ac.uk/news/2016/death-dr-john-stewart.html
