Patient H.M.: A Story of Memory, Madness, and Family Secrets

**For readers of *The Immortal Life of Henrietta Lacks* and *The Hare with Amber Eyes* comes a propulsive, haunting journey into the secret history of brain science by Luke Dittrich, whose grandfather performed the surgery that created the most studied human research subject of all time: the amnesic known as Patient H.M.** In the late 1930s, in asylums and hospitals across America, a group of renowned neurosurgeons embarked on a campaign to develop and refine a new class of brain operation—the lobotomy—that they hoped would eradicate everything from schizophrenia to homosexuality. These "psychosurgeons," as they called themselves, occupied a gray zone between medical research and medical practice, and ended up subjecting untold numbers of people to the types of surgical experiments once limited to chimpanzees.
