Theodor Schwann (1810-1882) studied with Johannes Muller in Berlin before moving in 1839 to the Catholic University of Leuven, Belgium, as Professor of Anatomy. Contemporaneously with M.J. Schleiden’s work at Jena (1804-1881) on plant structure and tissues, Schwann demonstrated the cellular basis of the human and animal body, which led to his Cell Theory, which states that all plant and animal bodies are fundamentally composed of cells and their products. Schwann’s work greatly aided the emergence of pathology, histology, and bacteriology.
