'''Matthias Jakob Schleiden''' ([[April 5]], [[1804]] - [[June 23]], [[1881]]) was a [[Germany|German]] [[botanist]] and co-founder of the [[cell theory]], along with [[Theodor Schwann]] and [[Rudolf Virchow]]. |
|||
Born in [[Hamburger]], Schleiden was educated at [[Ruprecht Karl University of Heidelberg|Heidelberg]] and practiced law in Hamburg, but soon developed his hobby of [[botany]] into a full-time pursuit. Schleiden preferred to study plant structure under the [[microscope]]. While a professor of botany at the [[University of Jena]], he wrote <cite>Contributions to Phytogenesis</cite> (1838), in which he stated that the different parts of the plant organism are composed of cells. Thus, Schleiden and Theodor Schwann became the first to formulate what was then an informal belief as a principle of biology equal in importance to the atomic theory of chemistry. He also recognized the importance of the [[cell nucleus]], discovered in 1831 by the Scottish botanist [[Robert Brown (botanist)|Robert Brown]],<ref>{{cite web|author=Trisha Creekmore|title = The Science Channel :: 100 Greatest Discoveries: Biology|publisher = [[Discovery Communications]]|url = http://science.discovery.com/convergence/100discoveries/big100/biology.html|accessdate = 2006-10-17}}</ref> and sensed its connection with [[cell division]]. |
|||

Schleiden was one of the first German biologists to accept [[Charles Darwin]]'s theory of [[evolution]]. He became professor of botany at the [[University of Tartu|University of Dorpat]] in 1863. |
