In the latest edition of Oxford Lives we interview Dr Jim Holt, retired consultant physician and former Director of Studies at Oxford Medical School. Dr Holt has spent most of his professional life in Oxford and has seen vast changes in medical practice. On the eve of his ninetieth birthday, Dr Holt reflects on his long and varied career and provides some forthright opinions on government health policies. We also learn about his time as a Fellow of Linacre College and how he had a substantial role in the setting up of Green College. Essential listening.
