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.
In 1839, Theodor Schwann would expand Schleiden's cell theory to include the animal world, establishing cell theory as the fundamental concept in biology. Schleiden included this article and others in a botany textbook--one that introduced new teaching methods which would dominate the instruction of botany for years.n his most well-known article, Schleiden described Robert Brown's 1832 discovery of the cell nucleus (which he renamed cytoblast). Schleiden knew that the cell nucleus must somehow be connected with cell division, but he mistakenly believed that new cells erupted from the nuclear surface like blisters.
