Professor Peter Thomas – Prof to his friends on the Hash
Peter Andrew Thomas (Prof) was born on 8th November 1961 and died on the 20th July 2024.

Nigel, David H, Mark Jones and I (David Evans) formed a Sunday running group many years ago, and Peter became a much-loved part of it. The photo was taken at Friston on 7th April 2024. It is still hard to believe that only a few short months later we would lose our great friend. Yet it is a joy to see him here, captured “looking good,” as we runners like to say. After so many years of running together, the memories with Peter are countless—far too many to record—but each one is treasured.
