The Lobotomist explores one of the darkest chapters of American medicine: the desperate attempt to treat the hundreds of thousands of psychiatric patients in need of help during the middle decades of the twentieth century. Into this crisis stepped Walter Freeman, MD, who saw a solution in lobotomy, a brain operation intended to reduce the severity of psychotic symptoms. Drawing on Freeman's documents and interviews with Freeman's family, Jack El-Hai takes a penetrating look at the life and work of this complex scientific genius.
