- Dutrochet, Henri (1776-1847) French botanist who prepared plant cells and studied them between 1824 and 1830. He looked for cells in animals, but was unable to find any. He also discovered and named the phenomenon of osmosis, which is the passage of a liquid through a semi-permeable membrane.

Figure 3: Dutrochet‘s Osmometer. Where ab is a semi-permeable membrane, and cd is the gauge used to measure the water height. The reading of the following lines reveals a conflict between Dutrochet and Poisson. Indeed, with this device, Dutrochet is going to demolish Poisson’s theory of the mechanism of osmosis.
(Rene Joachim) Henri Dutrochet. 1776-1847. French physiologist who discovered osmosis. He observed the diffusion of a solvent through a semi-permeable membrane, calling the process osmosis.
turned physiologist, Henri Dutrochet, known to science primarily for his discovery of the phenomenon of osmosis. The Schillers' volume, the first book devoted wholly to Dutrochet, comes as a welcome addition to the literature and as a valuable source for future study on Dutrochet and the development of physiology in the nineteenth century.
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. Henri Dutrochet was born on ...
Jan 1, 1994 · This essay explores the meanings of that discovery within the science of the early nineteenth century, including contemporary ideas on plant and animal microstructure and on physical explanations for the phenomena of life. Dutrochet is revealed as a 'romantic' exponent of 'organic physics'. Full text links.
theorists Henri Dutrochet and Francois Raspail; and its integration into the thinking of Schwann's German colleagues Johannes Muller, Rudolf K6lliker, Robert Remak, and Rudolf Virchow. The strengths and limitations of the book derive from Duchesneau's exclusive reli-ance on the analysis of important texts to trace the history of the theory. He ...
