He studied medicine at Bonn, where one of his teachers was the celebrated physiologist John Müller, and also at Würtzburg, and at Berlin where he obtained his degree in 1834. In his childhood, young Theodor was known to have been involved in constructing little machines in his childhood, no doubt having inherited a practical mechanical bent of mind from his father. http://www.newadvent.org/cathen/13592b.htm. His father was a goldsmith and was involved later in the printmaking business. New York: Robert Appleton Company.

He is credited with the development of cell theory and Schwann cells in … Theodor Schwann 1837 - 1839. Fact 1 Schwann has often been credited as the founder of modern histology. MLA citation. Transcription. Kölliker's cellular physiology and Virchow's cellular pathology are based on Schwann's theory. Fact 3 In 1834 he graduated, after studying medicine, from the universities of Bonn, Wurzburg and Berlin. Theodor Schwann (December 7, 1810 to January 11, 1882) was a German physiologist.
1 The thought marked a sea change in the study of anatomy and life itself. Senfelder, Leopold. German scientists Theodore Schwann and Mattias Schleiden studied cells of animals and plants respectively. Learn more about the mythic conflict between the Argives and the Trojans. Schwann, Theodor tā´ōdōr shvän , 1810–82, German physiologist and histologist. Matthias Schleiden found that all plants are composed of cells, and communicated the finding to Schwann, who had found similar structures in the cells. The Columbia Electronic Encyclopedia, 6th ed. He showed that yeast were tiny plant-like organisms, and suggested that fermentation was a biological process. In 1837 he discovered a digestive enzyme which he named pepsin. In a separate treatise he proved the weakness of the theory of spontaneous generation. His dissertation for the doctorate on the breathing of the embryo of the hen in the egg, "De necessitate æris atmosphærici ad evolutionem pulli in ovo incubato" attracted the attention of the medical world.

This is the cell theory for which he is best known. Theodor Schwann (December 7, 1810 to January 11, 1882) was a German physiologist. Imprimatur. He discovered the organic nature of yeast at the same time as Cagniard Latour, although independently of the latter, and proved that the yeast-cells take the material necessary for reproduction and development from the substance capable of fermentation.
He studied at the Jesuits College in Cologne. Schwann proved that animal cells are in morphological and physiological accordance with those of plants, and that all animal tissues proceed partly from cells and are partly composed of them. He established this theory in his chief work: "Mikroskopische Untersuchungen über die Übereinstimmung in der Struktur und dem Wachstum der Tiere und Pflanzen" (Berlin, 1839). Before this John Purkinje (1787-1869) had pointed out the analogy between the nuclei of the animal cell and of the plant cell, still Schwann deserves the credit of having developed and established this theory. Nihil Obstat. He began to study the physiology of muscle contraction. Infoplease is part of the FEN Learning family of educational and reference sites for parents, teachers and students.

Schwann also discovered the cells of the nails and feathers, what are called the Tomes fibres of the teeth, the nuclei of the smooth and striped muscle-fibres, and the envelope of the nerve-fibres (Schwann's envelope).

Fact 2 He has had Schwann cells named after him, which he discovered while researching the nervous and muscular tissues. In 1839 Theodor Schwann (1810-1882) published a monograph that declared all animals and plants are made from one single fundamental unit. New York: Robert Appleton Company, 1912. The editor of New Advent is Kevin Knight. He transferred to Berlin where he worked under Johannes Peter Muller.
