How did an architect help pioneer blood transfusion in the 1660s?Why did eighteenth-century dentists buy the live teeth of poor children?And what role did a sausage skin and an enamel bath play in making kidney transplants a reality?We think of transplant surgery as one of the medical wonders of the modern world. But transplant surgery is as ancient as the pyramids, with a history more surprising than we might expect. 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.

Bringing together philosophy, science and cultural history, Spare Parts explores how transplant surgery constantly tested the boundaries between human, animal and machine, and continues to do so today. Witty, entertaining and at times delightfully macabre, Spare Parts shows us that the history - and future - of transplant surgery is tied up with questions about not only who we are, but also what we are, and what we might become. .
