A quiet humour added savour to overturgid discussion and Dr McMichael had a constant care for comprehensibility so that no point was missed. ('What exactly do you mean by "C.V.A."? Ah yes, I thought you were talking about the coronary vessels: some people use it to mean "Cerebro-Vascular Accident": we might as well all mean the same thing.') And he was invariably punctiliously polite to the patient who was being demonstrated, taking care to put him at his ease. Dr McMichael was not actually made Professor until Sir Francis Fraser became Director of the British Postgraduate Medical Federation and resigned from the Chair. It made little difference. Professor McMichael had been Professor in all except name for years. Nor did the honours which crowded on him-Membership of the Medical Research Council, a term on the Medical team of the University Grants Committee, Fellowship of the Royal Society, a richly deserved Knighthood, Wellcome Trusteeship. All these left him still the same modest, competent teacher and Director of the Department of Medicine, a very wonderful man. His leaving the School might have been a disaster, but in fact it provided an association, through the Federation, instead of what would otherwise have been an imminent retirement. Long may he be spared to radiate a new and benign influence from Guilford Street.
