Theodor Schwann
German physiologist (–)
For the American Union Army officer, see Theodore Schwan.
Theodor Schwann (German pronunciation:[ˈteːodoːɐ̯ˈʃvan];[1][2] 7 December &#;&#; 11 January ) was a German physician and physiologist.[3] His most significant contribution to biology is considered to be the extension of cell theory to animals. Other contributions include the discovery of Schwann cells in the peripheral nervous system, the discovery and study of pepsin, the discovery of the organic nature of yeast,[4] and the invention of the term "metabolism".[5]
Early life and education
Theodor Schwann was born in Neuss on 7 December to Leonard Schwann and Elisabeth Rottels.[6] Leonard Schwann was a goldsmith and later a printer. Theodor Schwann studied at the Dreikönigsgymnasium (also known as the Tricoronatum or Three Kings School), a Jesuit school in Cologne.[6][7] Schwann was a devout Roman Catholic. In Cologne his religious instructor Wilhelm Smets&#;[de], a priest and novelist, emphasized the individuality of the human soul and the importance of free will.[8]:&#;&#;[6][7]

Matthias Jacob Schleiden helped develop the cell theory in Germany during the nineteenth century. Schleiden studied cells as the common element among all plants and animals. Schleiden contributed to the field of embryology through his introduction of the Zeiss microscope lens and via his work with cells and cell theory as an organizing principle of biology.
Schleiden was born in Hamburg, Germany, on 5 April His father was the municipal physician of Hamburg. Schleiden pursued legal studies at the University of Heidelberg in Heidelberg, Germany, and he graduated in He established a legal practice in Hamburg, but after a period of emotional depression and an attempted suicide, he changed professions. He studied natural science at the University of Göttingen in Göttingen, Germany, but transferred to the University of Berlin in Berlin, Germany, in to study plants. Johann Horkel, Schleiden's uncle, encouraged him to study plant embryology.
In Berlin, Schleiden worked in the laboratory of zoologist Johannes Müller, where he met Theodor Schwann. Both Schleiden and Schwann studied cell theory and phytogenesis, the origin and developmental history of plants. They aimed to find a unit of organisms common to the animal and plant kingdoms. They began a collaboration, and
