Contributions Of Louis Pasteur

Louis Pasteur was a famous scientist throughout the 1800s. He is known for his advancements in vaccination, microbial fermentation, and pasteurization. He is also known for his breakthroughs concerning disease prevention. He had a wide range of discoveries and advancements, these can be traced by going through the main points in his lifetime which were: his early life, professional career, research contributions of the Germ Theory, contributions to immunology and vaccination, and the honors and wards he received for all of his achievements. To begin, Pasteur 's early life. He was born in Dole France, on December 27, 1822. His parents were Jean-Joseph Pasteur and Jeanne-Etiennette Roqui. He began primary school in 1831, and was mostly interested

Now during his time of teaching and being a part of administration at these different schools, he was also researching and performing studies in his labs. These breakthroughs are what Pasteur tends to be remembered for. One of his most well-known works is his work on the Germ Theory of Fermentation. Around this time many people believed in spontaneous generation. Spontaneous generation states that living organisms would develop from nonliving matter. Pasteur disproved this using boiled broths. He placed them in tubes with longs necks that did not allow particles to get in. No bacteria formed when the tube had the long filter on it. When he used regular tubes, the bacteria would form, thus proving that the origins of bacteria were caused by spores or dust particles and not by the broth itself. This began the theory of biogenesis which then caused spontaneous generations to be forgotten and disregarded. From here, Pasteur 's research showed that beers, milks, and other beverages would be spoiled due to the growth of these micro-organisms. He then invented a process of heating up the liquids in order to kill them and disinfect the liquids. This process is known as Pasteurization. He also hypothesized that micro-organisms caused human and animal diseases and could be prevented by not letting them into the body. Because of this, Joseph Lister inventing antiseptics to use in surgery, which helped to prevent diseases

Throughout his works on germ theory, fermentation, and disproving the spontaneous generation theory, he was awarded the Copley Medal (1874), Jecker Prize (1861), and the Alhumbert Prize (1862). Some other wards and honors that were bequeathed unto Pasteur were the Leeuwenhoek Medal, Grand Croix of the Legion of Honor, and commander of the Brazilian Order of the Rose. Sadly, on September 28, 1895. He had suffered from strokes throughout his life and a major one in 1894 impaired him greatly, so much that he was not able to
