René Joachim Henri Dutrochet (14 November 1776 – 4 February 1847) was a French physician, botanist and physiologist. He is best known for his investigation into osmosis.
In the area of plant physiology, Dutrochet recognized the significance of green pigment in the use of carbon dioxide, investigated the mechanisms of respiration, light sensitivity, and geotropism, and showed that internal plant transport involves osmosis.
Dutrochet is also considered to be the founder of the cell theory; but his ideas are actually more in the nature of shrewd, intuitive anticipations rather than conclusions based on his own microscopic observations. His illustrations are not convincing and it seems that, at least in some cases, Dutrochet’s “globules” (cells) were optical ...
Cell theory was comprised of three tenets: that all plants and animals are made of cells, that all cells arise from division of preexisting cells, and that cells possess all the attributes of life (assimilation, growth, and reproduction).
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'.

Sep 1, 2003 · In the early 19th century, after learning about Nollet's previous success with bladder experiments, Dutrochet attempted to apply the same principle to movement of fluids across...
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 ...
