On going through my files I discovered some material related to W L Bragg’s 80th birthday celebrations. In 1970, Will (WHT) Taylor, Head of the Crystallography Laboratory at the Cavendish Laboratory, organised the 80th Birthday celebrations for W.L. Bragg. A symposium was held in his honour at the Royal Institution from April 1st to 3rd with a special dinner at Imperial College London on April 2. On this page I show the original Programme for the symposium. I recall in particular seeing for the first time the young Louise Johnson giving a splendid talk. Also the talk by Dave Lieberman included demonstrations of the memory metal Nitinol. In one of these he started with a piece of wire and heated it up, whereupon it formed the word Bragg. I saw WLB’s face light up when he saw it! I include here also the table seating plan for all the 300 guests at the dinner. You should find many famous names from the past who attended on that occasion.
