Sir Kenneth Calman’s extraordinary life story is based on a passionate love of learning — and it all began with him doing his homework by candlelight in a cupboard of his mum’s Glasgow council house. He went on to be at the forefront of three different medical revolutions — oncology, palliative care and the use of the arts in medical education — and to help guide the country through the BSE/VCJD health crisis. As Scotland’s and then England’s Chief Medical Officer the reforms he pushed through saved many lives by improving both cancer care and the training of doctors. Few people know as much about learning, laughter, health and happiness — or, come to that, sundials, beagles, cathedrals and cartoons. And few people have touched so many lives, especially those of the seriously ill and dying, with quite as much grace, humour and humanity.
