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.

Early career[edit]

Dutrochet was born on Néons to a noble family, soon ruined in the French Revolution. In 1799 he entered the military marine at Rochefort, but soon left it to join the Vendean army. He then left it to tend to his family's manor in Touraine. There, he was a keen addition to the scientific nation.

Contributions[edit]

His scientific publications were numerous, and covered a wide field, but his most noteworthy work was embryological. His Recherches sur l'accroissement et la reproduction des végétaux, published in the Mémoires du museum d'histoire naturelle for 1821, procured him in that year the French Academy's prize for experimental physiology. In 1837 appeared his Mémoires pour servir a l'histoire anatomique et physiologique des végétaux et des animaux, a collection of all his more important biological papers.

He investigated and described osmosis,[1] respiration, embryology, and the effect of light on plants. 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 Mauritian plant genus Trochetia was named in his honour.
