Do No Harm
Henry Marsh · first published 2014 · ISBN 9781780225920
A British neurosurgeon with four decades of operating experience recounts cases where his judgment had to be precise or someone would be permanently disabled or dead. Marsh doesn't hide his mistakes, his arrogance, or the moments when he had to tell a patient that surgery would likely kill them. The book conveys both the intellectual fascination of neurosurgery and its enormous weight.
On our lists
Marsh models the kind of physician who grows wiser through experience and honesty about failure. His respect for the fragility of the human brain and the lives that depend on his hands shows what mature medical judgment looks like. It's a corrective to the fantasy of the infallible surgeon.
Marsh's willingness to own his failures is rare in surgeon memoirs. He shows accountability and doubt, not just technical skill. This is the most realistic account of what surgical practice actually costs and how surgeons navigate irreversible choices.
