Matthias Jakob Schleiden (April 5, 1804 - June 23, 1881) was a German botanist and co-founder of the cell theory, along with Theodor Schwann and Rudolf Virchow.

Born in Hamburg, Schleiden was educated at 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 Contributions to Phytogenesis (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, [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] 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 Dorpat in 1863.

He died in Frankfurt am Main on 23 June 1881. ["Schleiden, Matthias Jakob" in "Encyclopædia Britannica Standard Edition 2004 CD-ROM", accessed 06 January 2008]
