Tully Memorial Medal. As the winner of the Tully Medal Keith was immediately elected to the Gemmological Association’s council, which he served faithfully until his calling up into the Royal Corps of Signals during the early years of World War II. He was posted to Singapore and it was not long afterwards that the Japanese invaded and he found himself a Prisoner of War. A number of his fellow POWs were taken to Thailand to build the infamous Burmese railroad, but Keith was taken to mainland Japan, where he and his fellow inmates were forced to labour making steel for the Japanese war effort, surviving on the poorest of diets for some I was extremely sad to receive the news three and a half years. It has to be said that that Keith had passed away, as this was not anyone who can survive such conditions only a personal loss for me, but a great loss for such a period has indeed to be quite for the entire gemmological world.
