Sir Peter John Morris. 17 April 1934—29 October 2022

Peter Morris was one of the leading pioneers of transplantation in the twentieth century. Although his main clinical focus was on kidney transplantation, his scientific achievements had a profound effect on the whole of the transplant community. Like many surgeons he did not set out to be a kidney transplant surgeon, but over the course of his training his interest in both the clinical and scientific aspects grew and he was one of those rare people who was able to combine a scientific mind with clinical expertise. His major contribution to science was in the understanding of the role of antibodies in transplantation and of minimizing the problems of rejection, and it was for this work that he was elected a Fellow of the Royal Society. He spent the majority of his career as head of the Nuffield Department of Surgery in the University of Oxford and subsequently became President of the Royal College of Surgeons of England and was active in research and writing until shortly before his death. †
