Louis Pasteur: A National Hero Essay

Dr. Charbonnet believed that diseases appeared within humans similar to how certain forms come from inanimate objects like fleas from dust; this is called spontenous generation. Charbonnet argued that the microbes are the result of disease meaning that the microbes are not the reason for causing an illness but come after someone contracts a disease. Unlike Pasteur’s idea, he said that microorganisms are

Louis Pasteur was magnificently a genius. His life was an example of hard work and persistence. He was called “The father of modern hygiene, public health and much of modern medicine, as well as the father of microbiology and immunology.” As a scientist, he made many discoveries and experimentations that are benefits to human and animals. Although sometimes his claims raised controversies, Louis Pasteur investigated, revised deeper and deeper his claims to bring up more evidences that lead him to more and more discoveries. Today, because of his claims; we know the correlation or causation between putrefaction and fermentation. We know what makes the milk spoiled, and how to prevent people to overuse it by putting an expiring date on the gallon.

In 1854 Louis Pasteur became a professor of chemistry at Lille. Shortly after, he became interested in fermentation. This was very helpful since alcohol making was a huge industry there. His interest in fermentation resulted in Louis developing many other interests. “In 1857 he jumped around from chemistry, biology then to medicine (Miller, 2002).” In 1860 he discovered pasteurization to kill bacteria in many food and beverages. This made a huge impact on the world. With pasteurization there would now be fewer illnesses due to people ingesting bacteria and parasites.

Epidemics of the 19th century were faced without the improved medical technologies that made the 20th and 21st-century epidemics rare and less lethal. It was in the 18th century that micro-organisms (viruses and bacteria) were discovered, but it was not until the late 19th century that the experiments of Lazzaro Spallanzani and Louis Pasteur disagreed with the spontaneous generation argument conclusively, crediting the germ theory and Robert Koch 's discovery of micro-organisms as the cause of disease transmission. Therefore, throughout the majority of the 19th century, there was only the most basic, understanding of the causes, amelioration and treatment of epidemic disease.

development of the germ theory of disease- with this historical brought improvement to science and technology in discovery

Louis Pasteur was born 27 December 1822 and grew up in a small village, Arbois in France. In school, he liked to paint and draw so his teachers encouraged him to work hard on that subject. However, his father thought that painting was just something Louis could do at his pastime and told him to study hard. Louis followed his advice and graduated in 1847 from a highly regarded school in Paris called École Normale Supérieure. There, he had studied molecular asymmetry and continued to examine it at the University of Strasbourg. Louis soon discovered that molecules that looked like they were the same could occur as mirror images of each other. The finding was a huge step forward in the microchemistry.

Louis Pasteur devised an experiment that would cure the rabies disease. Louis Pasteur experimented on a boy who was afflicted with the fatal disease. Louis Pasteur injected a vaccine, composed of ground up spinal cords from dead rabid dogs, into the afflicted patient, Andre. Every day, for three months, Louis Pasteur injected his patient with the vaccine until the boy no longer showed signs of rabies.

Louis Pasteur was a scientist. He led many scientific discoveries particularly in the study of germs and living organisms. It is through the work of Pasteur that we know to wash our hands to prevent that spread of germs, that medical instruments need to be sterilized, and his research on germ theory led to the development of antibiotics. His initial motivation was a love of science, but his research and life events led him to ask important science questions that begged to be answered. After his initial research on crystallization and how polarized light passed through them he became associated with another scientist named Biot. It was after testing Pasteur’s theories that the two became good friends and colleagues. Pasteur’s work into the study of disease and vaccination was further spurred on when two of his daughters died of typhoid.

Louis Pasteur was one of the brilliant scientists of his day. He was the one who discovered vaccines for Rabies, Anthrax, Cholera, Tuberculosis, and Smallpox. His most important discovery in medicine was the idea of injecting the disease into someone who already has the disease to build up immunity to it and help the body grow stronger. Besides the Rabies vaccine discovery, he is most known for discovering the idea called “the germ theory of disease,” which is the idea that specific germs cause diseases, and if they can determine the germ they can cure the disease by injecting it into the body. His motivation for these discoveries all started when a beer factory had fermented and the beer had gone sour. This caused the owner of the factory to question why and he brought in Louis Pasteur to help him figure out this anomaly. Louis figured out it was because of the microorganisms found in the beer that was causing it to sour. He began looking at different types of drinks as well like milk and

Who would have thought that soured beer would begin a study that would one day result in the discovery of several vaccines for deadly diseases? It all began when Bigo, a man who had manufactured beer from the sugar beet, went to see Pasteur. Louis Pasteur at the time was the Dean of the Faculty of Science at the University of Lille in France. Bigo asked Pasteur if he could discover why some of his beer became sour. Louis Pasteur used a microscope to study the vats of soured beer. He discovered that there were microorganisms in the beer. Because Louis Pasteur explored the possibility that these microorganisms were causing what is called putrefaction, a process of organic breakdown, he discovered many important facts. One of which was that microorganisms existed. He went on to explore the possibility that these microorganisms, or microbes, can be found airborne. Even when his peers scoffed at his ideas, Louis continued with his work. After discovering these microbes in wine, milk, and silkworms, Louis Pasteur believed that these microbes could affect human beings, that they could cause diseases.

Louis Pasteur was a French scientist in the 1800's. He is most famous for having invented the process of pasteurization that we still use today, but he developed many vaccines, including the one for rabies. He was highly motivated by his own curiosity and

Yeast is a considered an industrial microorganism because even though it is considered a living organism, and is the size of a pinhead, it is still a microorganism. Yeast is also available in different strains, such as pizza dough and bread dough yeast. Yeast is part of the fungi kingdom due to the fact that it cannot perform photosynthesis, what also is known about yeast is that they can live with or without oxygen, although it is a living organism. When yeast is stored in cool and dry environment it goes into a state of inactivity where it does not need to eat, but when you give it glucose, the organism begins to produce CO2 again. This was discovered by Louis Pasteur in 1857. Louis Pasteur discovered the functions of yeast by realizing that yeast is the key to alcoholic fermentation. Louis Pasteur found that when oxygen is not present adding sugar to

In the late 1800’s germ theories became the new focus for scientists. Louis Pasteur created systems for inoculation and the pasteurization method that kills germs in food products. In 1876, Robert Koch, the founder of bacteriology, discovered that deadly diseases could be caused by bacterium (Senior 2014). Scientists today, still use Koch’s germ theory to prove causes of contagions.

Many scientists say that several people saw his great idea and followed him on the way to discovery, but others opposed it. One of the followers was Louis Pasteur who seems to get most of the credit for the start of the germ theory. Pasteur was a French microbiologists and a dedicated man
