The book, originally published in German, was translated to English in 1847 by Henry Spencer Smith in an edition that also contained the treatise Phytogenesis, by Matthias Schleiden. [ 4 ] Besides the theoretical work, that Schwann called a "philosophical" section of general anatomy , [ 4 ] Schwann provided several plates with drawings of cells ...
Matthias Jakob Schleiden (1804–1881) Theodor Schwann (1810–1882) Credit for developing cell theory is usually given to two scientists: Theodor Schwann and Matthias Jakob Schleiden. [9] While Rudolf Virchow contributed to the theory, he is not as credited for his attributions toward it. In 1839, Schleiden suggested that every structural part ...
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).

This was ultimately concluded by plant scientist Matthias Schleiden [5] and animal scientist Theodor Schwann in 1838, who viewed live cells in plant and animal tissue, respectively. [3] 19 years later, Rudolf Virchow further contributed to the cell theory, adding that all cells come from the division of pre-existing cells. [3]
[14] [15] [16] In 1838, Matthias Jakob Schleiden affirmed that "formation of new cells in their interior was a general rule for cell multiplication in plants", a view later rejected in favour of Mohl's model, due to contributions of Robert Remak and others. [17]
