Theodor Schwann Essay 
Theodor Schwann was born in Neuss on December 7, 1810. He studied at the Jesuits College in Cologne and then at Bonn where he met the physiologist Johannes Peter Muller.
In 1837, Matthias Schleiden viewed and stated that new plant cells formed from the nuclei of old plant cells. After dining with him, the conversation turned on the nuclei of the plant and animal cells. Schwann remembered seeing similar structures in the cells of the notochord and immediately realized the importance of connecting the two discoveries each of them made. After making some comparisons, the scientists were able to confirm the resemblance. The discovery soon appeared in Schwann’s famous Microscopic Investigations on the Accordance in the Structure and Growth of Plants and Animals where he stated that all living things are composed of cells and cell products. This was the beginning of what came to be known as the cell theory. Schwann’s theory and observations became the foundation of histology. By the 1860’s, cell doctrine became the conventional view of the elementary anatomical composition of plants.
