well, my guess is 1838, but don't take my word for it.
Theodor Schwann was a German physiologist who discovered Schwann Cells also known as neurolemmocytes. He's also credited with discovering pepsin and inventing the term metabolism.
he is important cause all living things are composed of cells and cell products that are reproduced.
The first person to discover and name cells was Robert Hooke. He called them cells because they look like cells that monks used to live in. He looked @ cork through a microsope.
Theodor Schwann was a physiologist and made several discoveries. He contributed to cell theory, discovered Schwann cells, studied pepsin, made discoveries about yeast, and invented the term metabolism.
The three scientists who contributed significantly to the development of the cell theory are Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. Schleiden, a botanist, proposed that all plants are composed of cells. Schwann, a zoologist, extended this idea to animals, stating that all living organisms are made up of cells. Virchow later added to the theory by proposing that cells can only arise from pre-existing cells, challenging the idea of spontaneous generation.
