Professor Oliver Murray Wrong (7 February 1925 – 24 February 2012) was an eminent academic nephrologist (kidney specialist) and one of the founders of the speciality in the United Kingdom. From a background as a "salt and water" physician, he made detailed clinical observations and scientifically imaginative connections which were the basis of numerous advances in the molecular biology of the human kidney. Wrong himself contributed to much of the molecular work after his own "retirement". He dictated amendments to his final paper during his final illness in his own teaching hospital, University College Hospital (UCH), London. Though academic in his leanings, he was a compassionate physician who established a warm rapport with patients, a link he regarded as the keystone of his research. He belonged to a generation of idealistic young doctors responsible for the establishment of the UK's National Health Service in the post-War years.
Wrong was born in Magdalen College, Oxford, and was one of six children of Edward Murray Wrong and Rosalind Smith. Murray Wrong was a history lecturer and later vice-president of Magdalen, and his own father was the historian George MacKinnon Wrong, head of the department of history at University of Toronto. Rosalind, herself a historian, was the daughter of the Master of Balliol, A.L. Smith. Murray died of heart disease at the age of 38 and Oliver wrote an account of his father's illness, including consultations with Sir William Osler, in a vignette "Osler and my father". His father's early death and the Great Depression led to a split in the upbringing of the six children. Oliver was sent to Toronto with two of his sisters and was raised by his grandfather, George MacKinnon Wrong. Another sister was Rosalind Mitchison.
