He had undergone a rigorous training in all branches of surgery in children and adults. During the first world war, having been rejected for active service on account of an old poliomyelitis weakness of one leg, he was responsible for the work of two surgeons and two surgical registrars at University College Hospital and he prepared and examined all the associated surgical pathology. He was the foremost surgical teacher of his time. He had an encyclopaedic knowledge of surgery which he was able to impart with wit, originality and emphasis. He was completely devoted to surgery and to teaching and had few outside interests. After retirement he was able to indulge in his favourite hobby of gardening. He died on 23 January 1969 after a short illness. He was survived by his wife, a son and a daughter, both of whom, like their parents, are doctors.
