DUTROCHET AND THE CELL THEORY By J. Walter Wilson THE publication of Schwann's Mikroscopische Un-tersuchungen in I839 ushered in a new epoch in Biology. From then on the cell theory, in spite of its "inadequacies," supplied the framework of much of the most important biological thinking and re-search. It replaced the vague notions of "paren-
He has been given credit for discovering cell biology and cells in plants and the actual discovery of the process of osmosis. His early researches into the voice introduced the first modern concept of vocal cord movement.
The French botanist Charles-François Brisseau de Mirbel (1776–1854) suggested that plants were constituted by a set of membranes with a lot of pores. A few years later, René Joachim Henri Dutrochet (1776–1847), who had discovered the osmotic phenomenon, claimed that cells constituted plants.

HENRI DUTROCHET AND FRENCH PHYSIOLOGY DURING THE 1820s* J. V. PICKSTONE In 1826, René-Joachim-Henri Dutrochet (1776-1847), working in the small laboratory of his family home near Chateau Renault, discovered the phenomena which he named endosmosis and exosmosis. On October 30th of that year, he announced his results to the Paris Academy of ...
Among them, Henri Dutrochet (1776–1847), a self-taught French medical doctor, is probably the least recognized. The aim of this article is to relate the life of this independent investigator and show his contribution to the identification of the cell as the basic building block of plant and animal tissues.
