Louis-Antoine Ranvier was a French physician, pathologist, anatomist and histologist, who discovered nodes of Ranvier, regularly spaced discontinuities of the myelin sheath, occurring at varying intervals along the length of a nerve fiber.

As a person Ranvier was always precise and accurate, he possessed the ideal personality for the painstaking histological research for which he became famous.
His work was noted for its precision, thoroughness, and simple but effective techniques. He preferred disassociations (or fine dissections) to sectional cuts; and whenever possible he worked with thin membranes that were naturally dissociated. His few section cuts were usually made by hand rather than with the microtome. Osmic acid, alcohol, and bichromates were his usual fixing agents. Like Bernard, he had only contempt for statistics. Although he recognized the necessity for forming hypotheses in his experimental work, he disliked theorizing.
Because Ranvier rarely discussed the theoretical implications of his works, he is almost unknown to historians today.
Independent, unsociable, often rude, and seemingly insensitive, he was admired and feared more often than loved by his students and colleagues.
Ranvier maintained the importance of learning the relation between structure and function: "Il faut étudier leurs propriétés et leurs fonctions à l'aide de l'expérimentation le plus delicate, il faut faire, en un mot, l'histologie expérimentale. Tel est le but suprême des nos recherches, telle est la base de la médecine future."
"We must study their properties and functions with the most delicate experiment, we must, in a word, make experimental histology. This is the ultimate goal of our research, this is the basis for future medicine. "
