Oliver Wolf Sacks, CBE (9 July 1933 - 30 August 2015), was a distinguished British neurologist, naturalist, historian of science, and writer, renowned for his work exploring the complexities of the human brain and neurological disorders. Born in London, Sacks pursued his medical degree at The Queen's College, Oxford, graduating in 1958 before relocating to the United States, where he would spend the majority of his professional life. Upon moving to the U.S., Sacks interned at Mount Zion Hospital in San Francisco and completed his neurology and neuropathology residency at the University of California, Los Angeles (UCLA). He later joined the Beth Abraham Hospital in the Bronx, working with patients affected by encephalitis lethargica, a severe epidemic sleeping sickness that had rendered many individuals unable to move independently for decades. His groundbreaking work with these patients inspired his acclaimed 1973 book, Awakenings, a moving account of their lives and his innovative treatment methods. Awakenings brought Sacks international fame and was later adapted into an Academy Award-nominated film in 1990, featuring Robin Williams as Sacks and Robert De Niro as one of his patients. Through his writing and compassionate approach to medicine, Oliver Sacks profoundly impacted both the scientific and literary worlds, leaving a lasting legacy that expanded public understanding of neurological conditions.
