René Joachim Henri Dutrochet
(1776–1847) French physiologist
Born in Néon, France, Dutrochet began medical studies while serving in the army in Paris in 1802. After graduating in 1806 he served as an army surgeon in Spain. However, through illness he resigned his post in 1809 and thereafter devoted his time to natural science.
In 1814 he published his investigations into animal development, suggesting a unity of the main features during the early stages. Later research into plant and animal physiology led to his assertion that respiration is similar in both plants and animals. In 1832, Dutrochet showed that gas exchange in plants was via minute openings (stomata) on the surface of leaves and the deep cavities with which they communicate. He further demonstrated that only cells containing chlorophyll can fix carbon and thus transform light energy into chemical energy. Dutrochet studied osmosis and suggested it may be the cause of ascent and descent of sap in plants. Although sometimes lacking in accuracy, the importance of his work lies mainly in his endeavor to demonstrate that

(b. Néon, France, 14 November 1776; d. Paris, France, 4 February 1847)
animal and plant physiology, embryology, physics, phonetics.
Dutrochet was born at a seignorial mansion near Poitiers; he was the eldest son of wealthy and noble parents. His early childhood was spoiled by club-foot, which—after unsuccessful medical consultations—was completely healed by a renowned healer, who was also a hangman.
The Revolution brought expropriation of family property after his father emigrated; Dutrochet was therefore forced to rely on his own resources. He volunteered for the navy in 1799, then deserted and joined his brothers in the last Royalist units. Following 18 Brumaire, which with the accession of Bonaparte to the Consulate brought an end to the Royalist resistance and a general amnesty, Dutrochet spent two peaceful years with his family. He was, however, dissatisfied with such an empty and useless life, so in 1802, at the age of twenty-six, he went to Paris to study medicine. Graduating in 1806, he qualified as a military medical officer in 180
