Giovanni Di Chiro (October 17, 1926 – August 27, 1997) was an Italian-American neuroradiologist known for his work in the use of medical imaging techniques, such as computer-assisted tomography, to study the central nervous system.
He was the second of four children of Umberto di Chiro, a professor of Greek and Latin in Campobasso, and his wife, Antonietta.
Giovanni began attending school in Campobasso when he was four years old, and he and his family moved to Naples when he was thirteen.
During World War II, he studied medicine at the University of Naples, and received his medical degree from there in 1949.
In October 1957, he began working at the National Institute of Neurological Diseases and Blindness as a visiting scientist, and in January 1958, he established what became known as its Neuroimaging Branch.
