Theodor Schwann was a German physiologist and scientist who lived from December 7, 1810, to January 11, 1882.Applying cell theory to animals is considered his most outstanding contribution to biology. Of his many achievements, he discovered Schwann cells in the peripheral nerves, discovered and investigated pepsin, found yeast’s organic origin, and created the phrase metabolism.The basis of his cell theory was the conclusion of his research which indicated that all living things are made up of cells. He looked beyond considering the nerve cells as one single cell and decided to study it closely. This helped him determine that nerve cells are surrounded by different cells, which help with the transmission of signals. As he was the one who identified these cells, they were named Schwann cells.

Leonard Schwann worked as a jeweler before becoming a publisher.Theodor Schwann was a student at Cologne’s Dreikönigsgymnasium, also famous as the Tricoronatum or Three Kings School. Schwann was a devout believer of the Roman Catholic faith. Wilhelm Smets, a preacher and author who taught him at Cologne emphasized the human spirit’s distinctiveness and the value of free will.He was 18 years old when he met and was inspired by biologist Johannes Müller, a pioneer in practical physiology and anatomy techniques, at the University of Bonn, where he was pursuing medical and biological sciences. Müller would go on to publish Elements of Physiology, which would become the most widely used physiology textbook in the 1800s.Müller was a vitalist, believing that a life force from within an organism generates new cells. He believed in science obtained through observation. At the time, this was a commonly accepted idea. In the year 1831, Schwann began his clinical study in Würzburg. He returned to the University of Berlin two years later as a Ph.D. student, rejoining Johannes Müller, who had relocated from Bonn to Berlin.In 1833–1834, he worked on his thesis with Müller as his advisor. The importance of oxygen throughout the embryonic growth of the chicken was the subject of Schwann’s thesis. To do the same, he devised and built an apparatus that enabled him to pump oxygen and hydrogen out of the incubation chamber periodically. He was able to determine the essential period during which the eggs need oxygen as a result of this.

He is, nevertheless, known for a variety of many other inventions and accomplishments.At the dawn of biology, as we know it, he was among the earlier researchers involved in defining our knowledge of the basic and vital principles of living cells, structure, and physiology.The ‘cellular concept,’ which states that all living creatures are made up of fundamental elements known as cells, is one such foundational notion on which most of our understanding of biological study is based. Schwann was among the creators of this essential principle. During his career, he also became interested in the microscopic examination of nerve and muscle cells, blood arteries, and gastrointestinal physiology. He made several significant discoveries that lay the framework for establishing additional scientific disciplines.He conducted a series of tests in the 1830s to see if the concept of spontaneous generation was genuine or incorrect. He used a glass tube to expose sterilized broth to heated air and found that no microorganisms were present. This persuaded him that the concept of spontaneous generation was incorrect.He discovered the involvement of microorganisms in alcohol fermentation and putrefaction about this time. After a lot of testing, he came to the conclusion that the chemical process of fermentation was started by yeast. However, his theory of fermentation was not accepted by other scientists until more than a decade later.What did Theodor Schwann discover?Schwann’s first – and, in many ways, best – tests were conducted in Berlin over a four-year period to give data for Müller’s Elements of Physiology.In 1835, there was very little knowledge of the digestion process. In 1824, William Prout observed that animal digestive fluids contain hydrochloric acid. Other compounds in digestive secretions, Schwann found, could also aid in the digestion of food. Schwann began researching digestive processes in the year 1836. He saw digestion as the activity of a physiological agent that could be described empirically as a ‘peculiar particular substance,’ despite the fact that it was not immediately visible or measurable.Schwann finally found the enzyme pepsin, which he purified and named in 1836 after successfully isolating it from the stomach lining. The name Schwann comes from the Greek word ‘pepsis,’ which means digestion. Pepsin was the first protease extracted from animal flesh. It could decompose albumin from egg white into peptones, he proved. More significantly, according to Schwann, such studies could someday ’explain the entire developing process of life in all organized bodies.‘The common understanding of life’s existence and biological functions at the time was predicated on the belief known as ‘Vitalism.’ According to this theory, ’life entities differ fundamentally from nonliving phenomena as they possess a nonphysical component and are driven by different principles than inanimate things.‘The principle that gave life was the living spark or power, which has been considered nonphysical. Schwann was among the first researchers to reject vitalism in favor of a mechanism of action or physical and chemical explanation of living systems, which proposed that physical and chemical properties might explain biomolecules in organisms and living beings without the need for nonphysical organization.Schwann’s work with yeast cells paved the way for ‘sudden creation’ to be abandoned as a model for explaining biological activity beginnings. He also described the yeast cell’s nature in the process.Schwann was especially interested in the cellular structure of muscle and nerve tissues, which led to the invention and characterization of Schwann cells and the involvement of Schwann cells in forming the Schwann cell sheath, which protects nerve fibers (which later came to be known as the myelin sheath).The presence of the myelin sheath, which is a distinctive property of myelinated nerve fibers in the central nervous system, has consequences for the speed of conductivity of nerve impulses, among other activities. He was also a pioneer in muscle cell contractility research, developing the first tension-length diagram. This work was continued by Du Bois-Reymond and Helmholtz, paving the ground for the discipline of neuromuscular physiology to flourish.Schwann had been a co-founder of the cell theory, which would change biology and lay the groundwork for understanding all molecular pathways and natural processes. Müller and his disciple Schwann had uncovered similar organisms in their microscopic examination. In 1837, a German biologist called Matthias Jakob Schleiden discovered that plants have fundamental constituents called cells, which matched the conclusions of Müller as well as his disciple Schwann, giving them more inspiration for their cell theory.Schwann and Schleiden are said to have had an intellectual exchange over dinner after Schwann noticed cellular features similar to those described by his colleague in plant cells in his microscopic research of animal nerve tissue (notochord).Throughout his work ‘Microscopical Investigations into the Conformance in the Configuration and Development of Plants and Animals,’ Schwann drew the connection and realized that cells were the ’elementary units of life’ for both plants and animals. Written in German in 1839 and afterward written in English by the Sydenham Community in 1847. Several other biologists backed up his findings, leading to the recognition that all biological things are made up of basic components cells, and products formed by cells.Inside a professional environment that inhaled the breath of vitalism, this was a new notion with far-reaching ramifications. Later, in 1857, doctor Rudolf Virchow expanded this concept and coined the phrase ‘Omnis cellula e cellula,’ which means every cell derives from another cell.By 1860, the cell concept had been evolved, paving the way for new research like Pasteur’s ‘germ theory’ and the birth of microbiological, molecular genetics, histopathology, contagious diseases, and pathology. This perspective also paved the way for further advances in our understanding of such molecular processes that govern chronic diseases physiology.When did Theodor Schwann contribute to the Cell Theory?Theodor Schwann developed the standard cell hypothesis in 1839. This hypothesis is divided into three parts.As per section one, every creature is made up of cells. According to the second section, cells are the building blocks of life. The conclusions obtained by Schwann and Matthias Schleiden in 1838 after comparing plant and animal cell results were the basis for these sections.Awards And Honors Of Theodor SchwannFor his physiological research on the formation of animal and vegetable textures, he was given the Copley prize in 1845. The Copley Medal is the United Kingdom’s most distinguished scientific honor, bestowed annually by the Royal Society of London ‘for remarkable achievements in research in any discipline of science’.In 1879, Schwann was appointed to the Royal Society and even the French Academy of Sciences. The body of every organism is composed of cells. Be it unicellular or multicellular with separate independent cells, at the fundamental level, and they are composed of cells. Significant discoveries were made in human anatomy by Theodor Schwann. There are various important aspects to everybody.There are the muscular tissues, ligaments cells, muscle contraction, peripheral nerve fibers, and many-many more. The adult animal tissues and animal cells are pretty similar to the ones of humans. Theodor Schwann observed animal tissues and animal cells to make this conclusion.Here at Kidadl, we have carefully created many interesting family-friendly facts for everyone to enjoy!
