What Is Cell Theory? by Marina CohenThis fascinating title examines the sequence of events that led to the formation of cell theory. In 1665, scientist Robert Hooke published Micrographia, the first significant work focused on miscroscopial observation. Later, Hookes groundbreaking work inspired scientists such as Theodor Schwann, Matthias Schleiden, and Rudolph Virchow and led to the creation of this fundamental biological principle that shaped modern biology.
Interesting Theodor Schwann Facts
It was Robert Hooke in the 17th century who first observed cells and gave them that name, but the German botanist Matthias Schleiden —81 was the first scientist to appreciate their importance. All living organisms either consist of a single cell or are made up of cells, and organisms grow and reproduce by the division of cells.
Theodor Schwann Theorizes that All Living Things are Made of Cells
Cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke , and began the scientific study of cells, also known as cell biology. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in This is usually credited to Matthias Schleiden and Theodor Schwann.
Theodor Schwann , born December 7, , Neuss , Prussia [Germany]—died January 11, , Cologne , Germany , German physiologist who founded modern histology by defining the cell as the basic unit of animal structure. In , while investigating digestive processes, he isolated a substance responsible for digestion in the stomach and named it pepsin , the first enzyme prepared from animal tissue. That same year his seminal work, Microscopical Researches into the Accordance in the Structure and Growth of Animals and Plants , was published. In it he extended to animals the cell theory that had been developed the year before for plants by German botanist Matthias Jacob Schleiden , who was working at the University of Jena and who Schwann knew well. At Leuven Schwann observed the formation of yeast spores and concluded that the fermentation of sugar and starch was the result of life processes.
Theodor Schwann is best remembered for the eponymous Schwann cell that he studied and described in his microscopic studies of nervous tissue. However, his most important contribution to science would be the fact that he was one of the founders of the 'Cell doctrine' which proposed that all living beings were made of fundamental units called cells - a foundational principle on which rests much of our understanding of biological science. Schwann was one of the first scientists to break away from vitalism to lean toward a mechanistic or physico-chemical explanation of living processes which proposed that the biological processes in cells and living beings could be explained by physical and chemical phenomena. He was also involved in describing the physiology of bile and the enzyme pepsin which furthered our understanding of the physiology of digestion. His contributions to biology and medicine has paved the way for the emergence and blooming of several fields of study such as microbiology, pathology, histology and the principle of antibiotics.
