Holloway was born inPhiladelphia, Pennsylvania.[2] His work on theTaung Child was one of the first to suggest brain reorganization occurring before the increase of brain size in hominids. His claim that the lunate sulcus, a sulcus which marks the boundary of the occipital lobe, was in a posterior position to that of apes suggests that the reduction of the occipital lobe was accompanied by enlargements of parts of the brain associated with higher cognitive function.[3] Holloway died in New York City on March 12, 2025, at the age of 90.[2]
