Dr. Clinton Woolsey was a leading 20th-century neuroscientist for almost 4 decades. His most significant achievements were the novel use and refinement of evoked potential techniques to functionally map mammalian brains, the discovery of secondary cortical areas, and a wide repertoire of comparative neurofunctional studies across many species. The authors discuss his life and work through a historical context with contemporaries, highlight the primitive state of brain mapping before Woolsey, and review his involvement in advancing its rapid development through work at both Johns Hopkins University and University of Wisconsin in Madison. Dr. Woolsey's lasting impact on basic and clinical neuroscience, neurosurgery, and neurology and his important roles as a scientific mentor and leader are also described.
