What did Theodor Schwann do within his life span to become a Famous Scientic?
Im doing a science project on him and i need to know all i can about this manAnswers: I dunno sorry, wikipediaAt the University of Berlin, Schwann again come into contact with Müller, who convinced him that he should follow a scientific career. Very soon after he begin to work under Müller, he had his first success. From extracts which he made of stomach bin liner, Schwann demonstrated that a factor other than hydrochloric acid was operating contained by digestion. Two years later, in 1836, he succeeded in isolating the live principle, which he named pepsin.
Between 1834 and 1838 Schwann undertook a series of experiments designed to settle the question of the truth or falsity of the concept of spontaneous social group. His method was to expose sterilized (boiled) broth only to heated air surrounded by a glass tube, the result being that no micro-organisms were detectable and no chemical changeover (putre-faction) occurred in the broth. He was convinced that the notion of spontaneous generation was false. His sugar fermentation studies of 1836 also led to his discovery that yeast originate the chemical process of fermentation.
At Müller's suggestion, Schwann also began research on muscle contraction and discovered striated muscles in the upper portion of the esophagus. He also identified the delicate sheath of cell surrounding peripheral nerve fibers, which is now name the sheath of Schwann
Vitalism and germ theory
Schwann was the first of Müller's pupils to break with vitalism and work towards a physico-chemical explanation of go. Schwann's rediscovery of the cell came when he was paying particular attention to the cytoplasm of a plant cell, and notice its jelly-like consistency. He went on to view animal cells, and noted that they have different properties. Müller also directed Schwann's attention to the process of digestion, which Schwann showed in 1837 to depend essentially on the presence of a ferment he called pepsin. Schwann also examined the question of spontaneous age group, which led to its eventual disproof. In the course of his experiments, he discovered the organic nature of yeast. In reality, the whole germ theory of Pasteur, as well as its antiseptic applications by Lister, can be traced to Schwann's influence.
Once, when Schwann be dining with Matthias Jakob Schleiden (who in 1837 had view and stated that new plant cells formed from the nuclei of hoary plant cells) in 1837, the conversation turned on the nuclei of plants and animal cells. Schwann remembered seeing similar structures within the cells of the notochord (as had been shown by Müller) and instantly realize the importance of connecting the two phenomena. The resemblance was confirmed without deferment by both observers, and the results soon appeared in his famous Microscopic Investigations on the Accordance surrounded by the Structure and Growth of Plants and Animals, in which he declared that "All living things are composed of cells and cell products." Thus cell theory be definitely constituted. In the course of his verification of cell theory, within which Schwann traversed the whole field of histology, he proved the cellular origin and nouns of the most highly differentiated tissues including nails, feathers, and tooth enamel.
His generalization become the foundation of modern histology, and in the hands of Rudolf Virchow (whose cellular pathology was an inevitable conjecture from Schwann) placed modern pathology on a truly scientific basis. Related Questions:
