Theodor Schwann (1810-1882)

Theodor Schwann was born in Neuss, Germany. He studied medicine in Berlin, and after graduation went on to do an assistantship in anatomy. In 1838, Schwann and Matthias Jakob Schleiden (1804-1881) developed the "cell theory." Schwann went on and published his monograph Microscopic Researches into Accordance in the Structure and Growth of Animals and Plants in 1839. In the monograph, Schwann identified the common features of all cells - plants and animals, and he illustrated many different cell types. Although Schwann did change the definition of cell by stressing the internal cellular components, he believed incorrectly that cells could arise from assembly of cellular fluids. In 1839, Schwann was appointed Professor of Anatomy at the University of Louvain. In 1848 he moved to Li�ge where he taught physiology and comparative anatomy.

Description:
Theodor Schwann redefined the cell as a living unit.
