How did an architect help pioneer blood transfusion in the 1660s? Why did eighteenth-century dentists buy the live teeth of poor children?

Paul Craddock takes us on a journey - from sixteenth-century skin grafting to contemporary stem cell transplants - uncovering stories of operations performed by unexpected people in unexpected places.
