Rudolph Virchow suggested that all cells come from pre-existing cells. His aphorism'omnis cellula e cellula' meaning every cell from a pre-existing cell became the foundations of division, even if the process was not fully understood then.
He also stated that not all plants are made up of cells,which eventually lead to the creation of the cell theory.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.
He presented a theory of evolution.

Cell Theory
Before the cell theory it was pre-renaissance. The renaissance was the boom of art and science. So, before the cell theory was religion.

One scientist who did not make a major contribution to cell theory was Lamarck. While Lamarck made significant contributions to evolution with his theory of inheritance of acquired characteristics, his work did not significantly impact the development of cell theory.

C. Matthias Jakob Schleiden is the scientist who did not make a major contribution to cell theory. Schwann and Virchow were the ones who proposed key components of cell theory.
Robert Brown's contribution is mainly developing cell theory. (You can find another set of answers- type in "contribution of Robert brown in the development of cell theory.) All i can remember is this:. (sorry if not much) -He named 'nucleus" and suggests its importance in fertilization
