The German biologist Theodor Schwann (1810-1882) is considered a founder of the cell theory. He also discovered pepsin, the first digestive enzyme prepared from animal tissue, and experimented to disprove spontaneous generation.Theodor Schwann was born at Neuss near Düsseldorf on Dec. 7, 1810. At the University of Bonn, which he entered in 1829, he met Johannes Müller, the physiologist, whom he assisted in his experiments. Schwann continued his medical studies at the University of Würzburg and later at the University of Berlin, from which he graduated in 1834. His doctoral dissertation dealt with the respiration of the chick embryo.Contributions to Physiology and AnatomyAt the University of Berlin, Schwann again came into contact with Müller, who convinced him that he should follow a scientific career.

Further Reading Excerpts in English translation from Mikroskopische Untersuchungen are found in the following works: Forest Ray Moulton and Justus J. Schifferes, eds., The Autobiography of Science (1945; rev. ed. 1960); Augusto Pi Suñer, Classics of Biology (1955); Friedrich S. Bodenheimer, The History of Biology: An Introduction (1958); and George Schwartz and Philip W. Bishop, eds., Moments of Discovery (2 vols., 1958). There is no biography of Schwann. Gilbert Causey in The Cell of Schwann (1960) devotes the first chapter to a sparse recital of the essential details of Schwann's life. Erik Nordenskiöld, The History of Biology (1928; new ed. 1935), gives a brief biographic account, as does Gordon R. Taylor, The Science of Life (1963). A good treatment of the cell theory and Schwann's part in it is in William A. Locy, Biology and Its Makers (1908; rev. ed. 1915).
