What did Schwann discover?
Schwann discovered the enzyme pepsin and discovered glial cells in nerves – these are now known as Schwann cells. He also identified the role that microorganisms play in alcohol fermentation.
What are Schwann accomplishments?
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.
How did Schwann contribute to the cell theory?
Schwann is most famous for his contributions to the cell theory. Schwann concluded three things that became vital components of the cell theory. First, Schwann concluded that both plants and animals were composed of cells. Second, these cells have independent lives.
What was Theodor Schwann known for?
Theodor Schwann, (born December 7, 1810, Neuss, Prussia [Germany]—died January 11, 1882, Cologne, Germany), German physiologist who founded modern histology by defining the cell as the basic unit of animal structure.

What did Schleiden and Schwann both discover?
Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.

What did Schwann discover about fermentation?
Schwann identified the role of microorganisms in putrefaction and alcohol fermentation. He carried out a variety of fermentation experiments and by 1836 had gathered enough evidence to convince himself that the conversion of sugar to alcohol during fermentation was a biological process that required the action of a living substance (yeast) ...
