Schleiden's theory of free cell formation through crystallization was refuted in the 1850s by Robert Remak, Rudolf Virchow, and Albert Kolliker. [5] In 1855, Rudolf Virchow added the third tenet to cell theory. In Latin, this tenet states Omnis cellula e cellula. This translated to: 3. All cells arise only from pre-existing cells
Illustration of Virchow's cell theory. Virchow is credited with several key discoveries. His most widely known scientific contribution is his cell theory, which built on the work of Theodor Schwann. He was one of the first to accept the work of Robert Remak, who showed that the origin of cells was the division of pre-existing cells. [29]
According to historian Paul Weindling, Rudolf Virchow, one of the founders of modern cell theory, plagiarized Remak's notion that all cells come from pre-existing cells. [2] Remak had concluded this after observing red blood cells from chicken embryos in various stages of division.
1839: Theodor Schwann [43] and Matthias Jakob Schleiden elucidated the principle that plants and animals are made of cells, concluding that cells are a common unit of structure and development, and thus founding the cell theory. 1855: Rudolf Virchow stated that new cells come from pre-existing cells by cell division (omnis cellula ex cellula).
In 1856, he returned to Berlin.He summarized the cell theory with the Latin phrase "omnis cellula a cellula" which means all cells come up from cells, in 1855. Virchow came up with the third part of the cell theory that states the “all cells come from preexisting cells.” In Die Cellularpathologie, he set out methods and objectives of ...
Illustration of the cell theory in the first edition of Virchow's Archiv für Pathologische Anatomie und Physiologie, 1847. The rise of popular materialism was encouraged by a critique of romantic-idealistic natural philosophy, [5] which became widespread after 1830 and had an equal influence on natural science, philosophy, and politics.

Rudolf Virchow (1821–1902) is generally recognized to be the father of microscopic pathology. While the compound microscope had been invented approximately 150 years prior, Virchow was one of the first prominent physicians to emphasize the study of manifestations of disease which were visible only at the cellular level.
