For me, Jon was without doubt one of the finest scientists the field has
known. His ability to produce volumes of top notch science will surely be
hard for anyone to match. I was devastated to hear that we have lost this
truly remarkable person who I remember with much affection. But I was
particularly touched now that the reports from the inquest into his death
have appeared, which fill me with an even greater sense of sadness. What a
tragedy....
