What did Theodor Schwann have to do with cells? Theador Schwann is the physiologist that discovered cells now called schwann cells. These are the cells that produce myelin sheets that wrap around the axons of of neurones. Tâ¦his creates the myelin sheeth which speeds up the conduction of action potentials. These cells exist only in the periphery but there are similar cells in the CNS.
The German biologist Theodor Schwann (1810-1882) is considered a founder of the cell theory. He also discovered pepsin, the first digestive enzyme prepared from animal tissue, and experimented to disprove spontaneous generation. Theodor Schwann was born at Neuss near DÃ¼sseldorf on Dec. 7, 1810. At the University of Bonn, which he entered in 1829, he met Johannes MÃ¼ller, the physiologist, whom he assisted in his experiments. Schwann continued his medical studies at the University of WÃ¼rzburg and later at the University of Berlin, from which he graduated in 1834.
