One of the first young men to start working without salary with Buchman.
After service with the Indian Army in France in the First World War, when he was awarded the Military Cross, Loudon Hamilton went up to Oxford and took a two-year philosophy course. Towards the end of that time, in May 1921, Dr Frank Buchman paid his first visit to Oxford. One evening he was a guest in Loudon Hamilton's rooms in Christ Church at a meeting of the Beef and Beer Club. Out of this grew the Oxford Group, later known as Moral Re-Armament and then Initiatives of Change. In a 1968 short booklet, How it all began, Loudon Hamilton describes the experience.
