A remarkable examination of how neuroscience works * Economist, Books of the Year * Luke Dittrich has achieved something remarkable in Patient H.M. This book succeeds on every level: as a fresh look at the most famous patient in medical history, as an expose of our dark history of psychiatry and neurosurgery, and, most powerfully, as a deeply personal investigation into the author's past. And yet, it's still a page-turner that reads like a thriller. It deserves a spot next to the great medical histories The Immortal Life of Henrietta Lacks, The Ghost Map, and The Emperor of All Maladies. -- Susannah Calahan, author of Brain on Fire In Patient H.M. Luke Dittrich explores the limits of science and the mind. In the process, he rescues an iconic life from oblivion... This is classic reporting and myth-making at the same time. -- Colum McCann It felt as if I read this book in one breath. Patient H.M. is a fascinating, powerful investigation, a matroyshka doll of nested stories about the past and present, remembering and forgetting. Luke Dittrich's quest to understand the amnesiac patient who taught the world so much about memory - and ourselves - leads him to the shoals of his own family tragedy, and an ending that will break your heart. But it's his beautiful unfolding of the story, the art of his sentences and reportage, that you'll never forget. -- Michael Paterniti Patient H.M. tells one of the most fascinating and disturbing stories in the annals of medicine, weaving in ethics, philosophy, a personal saga, the history of neurosurgery, the mysteries of human memory, and an exploration of human ego. Sweeping, meticulous, and seamless - with an ending that, like the best of scientific investigations, challenges everything that came before it. A monumental contribution to our understanding of medical research, and ourselves. -- Dr Sheri Fink, Pulitzer prize winner
