Henri Dutrochet

Born 14 Nov 1776; died 4 Feb 1847 at age 70.Rene-Joachim-Henri Dutrochet was a French physiologist who discovered and coined the name for (1863) osmosis, the process in which a solvent passes through a semipermeable membrane into a region of greater solute concentration, thus equalizing concentrations on either side of the membrane. He also studied development of eggs of birds. He was the first to recognize that the take-up of carbon dioxide by plant cells depends on their green pigment. The light sensitivity, and geotropism of plants also drew his interest. He was one of the most successful champions, in animal as well as vegetable physiology, of the modern ideas which displaced the old vitalistic school of thought after 1820.«
