Jean Nageotte (8 February 1866 – 22 July 1948) was a French neuroanatomist born in Dijon.
He succeeded Louis-Antoine Ranvier (1835–1922) in what then became the chair of comparative histology at the Collège de France.
Nageotte specialized in anatomical research of the nervous system, and in his work stressed the importance of microscopic anatomy.
He performed research of nerve fibers and the myelin sheath, and conducted studies involving connective tissue.
In his 1910 article,[2] he surmised that glial cells behaves like an endocrine organ and secretes several molecules into the blood.
