René Joachim Henri Dutrochet (14 November 1776 – 4 February 1847) was a French

physiologist
. He is best known for his investigation into osmosis.

Early career

Dutrochet was born on

Vendean army.[1] He then left it to tend to his family's manor in Touraine. There, he was a keen addition to the scientific nation.[citation needed
]

In 1802 he began to study medicine at Paris, and was subsequently appointed chief physician to the hospital at Burgos, in Spain. After an attack of typhus he returned in 1809 to France, where he devoted himself to the study of the natural sciences.[1]

Contributions

His scientific publications were numerous, and covered a wide field, but his most noteworthy work was

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.[1]

He investigated and described

vocal cord
movement.

The Mauritian plant genus Trochetia was named in his honour.
