> John was a founder of the BLC (together with Robin Gandy if I remember
> rightly). Hiis own work was in many areas, starting with set theory, then
> recursion theory, (inventing the Register machine in a paper with Sturgis),
> models of arithmetic, incompleteness phenomena, and towards the end of his
> career working on PROLOG and fuzzy logic.   Besides all this he made Bristol
> a centre for mathematical logic in the UK, with many prestigious visitors in
> the early years. In particular it became a training ground in the 50's, 60’s
> for many who went on to academic careers, as well as in the 70's through its
> MSc in Mathematical Logic and Theory of Computation. He spent his whole working
> career at the Bristol department arriving there in 1946. 
>  
> He always struck me as an exceptionally kind person, an amusing and intelligent
> companion to be with, and most modest, as well as self-effacing in the best
> sense. He will be much missed.
> 
> A fuller appreciation will be composed at some point. There will be no funeral,
> but his family have indicated there will be a Memorial Service or Occasion at
> a date in the future, when a full tribute can be paid to him.
