OLIVER SACKS spent more than fifty years working as a neurologist and writing essays about the neurological predicaments of his patients. His articles appeared in The New Yorker, The New York Review of Books, and The New York Times, which referred to him as “the poet laureate of medicine.” His many bestselling books, including The Man Who Mistook His Wife for a Hat, Musicophilia, and Awakenings, have been translated into dozens of languages and enchanted millions of readers. Dr. Sacks was profiled by the filmmaker Ric Burns in the PBS American Masters film Oliver Sacks: His Own Life, and his book Awakenings inspired the Hollywood film starring Robert De Niro and Robin Williams.
