Schwann dedicated a chapter of the treatise to explicitly formulate the cell theory, stating that ("the elementary parts of all tissues are formed of cells” and that “there is one universal principle of development for the elementary parts of organisms... and this principle is in the formation of cells" (Henry Smith's translation, 1847).
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 ...
