Oliver Wolf Sacks (9 July 1933 – 30 August 2015) was a British neurologist, naturalist, historian of science, and writer. Born in London, Sacks received his medical degree in 1958 from The Queen's College, Oxford, before moving to the United States, where he spent most of his career. He interned at Mount Zion Hospital in San Francisco and completed his residency in neurology and neuropathology at the University of California, Los Angeles (UCLA). Later, he served as neurologist at Beth Abraham Hospital's chronic-care facility in the Bronx, where he worked with a group of survivors of the 1920s sleeping sickness encephalitis lethargica, who had been unable to move on their own for decades. His treatment of those patients became the basis of his 1973 book Awakenings, which was adapted into an Academy Award-nominated feature film, in 1990, starring Robin Williams and Robert De Niro.
His numerous other best-selling books were mostly collections of case studies of people, including himself, with neurological disorders. He also published hundreds of articles (both peer-reviewed scientific articles and articles for a general audience), about neurological disorders, history of science, natural history, and nature. The New York Times called him a "poet laureate of contemporary medicine", and "one of the great clinical writers of the 20th century". Some of his books were adapted for plays by major playwrights, feature films, animated short films, opera, dance, fine art, and musical works in the classical genre. His book The Man Who Mistook His Wife for a Hat, which describes the case histories of some of his patients, became the basis of an opera of the same name.
