Louis Ranvier (1835–1922): The Contribution of Microscopy to Physiology and the Renewal of French General Anatomy

Abstract

The French neurohistologist Louis-Antoine Ranvier (1835-1922), somewhat neglected in classical histories of nineteenth-century studies on the nervous system, developed a personal style, traditionally referred to as a synthesis between histology and physiology. Ranvier's research was not centered on the brain. Rather, he remained attached to the intimate nature of minute structures, with a style marked by the concept of generality. Ranvier's original style and role in the development of French histology and anatomie générale are analyzed, and their significance evaluated. Ranvier is reassessed as a prominent figure and as the leader in the renewal of the French anatomy.
