Louis Pasteur once said, “It is surmounting difficulties that makes heroes” (Louis Pasteur). His work brought him a great deal of satisfaction. Eventhough his journey was very difficult, he kept on doing what he loved. Although Louis Pasteur met personal challenges in life, he did not give up, but went on to develop pasteurization and a rabies vaccine. Louis Pasteur came into the world on December 27, 1822, in Dole, France. He grew up in Arbois with his father, Jean-Joseph Pasteur. His father earned the distinction of the Legion of Honor during the Napoleonic Wars (biography.com). His mother’s name was Jeanne- Etiennette Boqui. His parents had three more children besides Louis. Pasteur had one older sister and two younger sisters (The Doc). …show more content…
In order to go to this school he had to move back to Paris. He later passed the ENS exam with a high rank and won a prize for top physics student. He got his diploma in 1840 and later became a teaching assistant at Royal College high school (The Doc). He also received his bachelor of arts degree in 1840. By 1842 he earned his bachelor of science degree (biography.com). In 1843 Pasteur went to a teacher’s college in Paris. He listened to a lectures by chemist Jean-Baptiste-Andre Dumas. Later he became Dume’s teaching assistant. In 1845 Pasteur got his master of science degree, He later got an advanced degree in physical science. He received his doctorate in science in 1847(Louis Pasteur). While he was a professor at the University of Strasbourg, he met Marie Laurent. They got married on May 29, 1849, which led to their five children, but sadly only two survived through childhood. The three children died of typhus, this lead to Pasteur’s interest in infectious disease(biography.com). Pasteur became puzzled after graduating from the Ecole Normal Superieure, by the discovery of the German chemist Eilhardt Mitscherlich. Pasteur discovered the existence of molecular asymmetry, also known as the foundation of stereochemistry. Louis was given the professor job of chemistry and dean of the science faculty at the University of Lille in 1854 (Louis Pasteur). There was a problem with the manufacture of …show more content…
Pasteur made an unexpected discovery that the fermentation process could be arrested by passing air through the fermenting fluid, this process is known as the Pasteur effect. Pasteurization is seldomly used for wines that benefit from aging, but it is used for many foods and beverages, particularly milk. After Pasteur’s success with wine, he went on to study about beer. He proved that there was no spontaneous generation. In 1863, Louis Pasteur was elected to be a professor of geology, physics and chemistry at the school of Fine Arts. Pasteur was known as an expert of silkworms which later saved the silk industry. After his duties at the school of Fine Arts, he went to be a professor of chemistry at a University in Paris (Louis Pasteur). In 1868 Pasteur was partially paralyzed from a severe brain stroke, but he still continued his research. He spotted that although the two compounds had the same chemical composition they must have different structures somehow. He also noticed that there was two different types of tiny crystals, and observed that both solutions rotated, but in opposite directions. His experiment of the two solutions led to the field of stereochemistry. Organisms like bacteria was responsible for the souring of beer, milk, and wine. Bacteria could be removed by the boiling and cooling of the liquid. He completed his theory on April 20, 1862,

A remarkable breakthrough in medicine occurred in the late 1800s through the work of Louis Pasteur. Pasteur's experiments showed that bacteria reproduce like other living things and travel from place to place. Using the results of his findings, he developed pasteurization, which is the process of heating liquids to kill bacteria and prevent fermentation. He also produced an anthrax vaccine as well as a way to weaken the rabies virus. After studying Pasteur's work, Joseph Lister developed antisepsis, which is the process of killing disease-causing germs.
There is no greater example of this than the change of thought amongst people regarding Miasma. Until this time it was a long held belief that Miasma (polluted air) was the cause of illness. This shifting in the public’s conviction shows how both science and medicine can impact society. Consequently this shift in knowledge occurred as the result of one of history’s most significant contributions to science, the discovery of fermentation. Rosenberg identifies Pasteur’s discovery as one of the defining elements to the eventual identification and eradication of cholera. Rosenberg plainly outlines the changes occurring in the field of science and from his writing it could be assumed that this was also the first introduction to the ontological theory of disease (external source of illness). Pasteur’s fermentation experiments were occurring at the same time as the Cholera epidemic and his results showed that spontaneous generation was not to blame but instead a microscopic bacteria. Fungi as a source of illness among plants, animals, and humans was already widely accepted, as a result the causation of disease took a change of course and the foundation of Germ Theory was
In the span of only a few pages, L.B. Church has given us an overview of the winemaking process. He has done so with sufficient detail for those in the chemistry community to follow along, yet still in a cursory enough manner as to not bog them down with the unnecessary. Written as if it were the procedure of an experiment, he has given enough information for the experiment to be repeated, tested, validated and improved upon. And that is almost assuredly his goal from the very beginning, as it must be for any published author in the chemistry community.
Ludwig Mond from Germany was the founder of a British chemical industry and the discoverer of many important chemical processes. Chemical processes was what embryos went through to become people well-adapted to their environment. Without deep study into chemistry, the Brave New World wouldn’t have existed.
Gaston Leroux was born on May 6, 1868 in Paris, France. He was the son of a store owner. Leroux was raised in Normandy, where he spent most of his time on the coast. He loved sailing and unloading the herring catch. As a child, Gaston loved writing verse in his free time.
Louis Pasteur had been studying fermentation to explain why dairy and meat was going bad. He didn’t believe that it was spontaneous but rather there had to be a scientific explanation. When working with grapes and understanding that yeast was the driving agent in fermentation of grapes, he hypothesized that if you can protect grapes from fermentation, that people could be protected from infectious disease.
Louis Pasteur could easily be considered one of the greatest patrons of humankind his work in the discovery of vaccinations for rabies, anthrax, chicken cholera and silkworm diseases contributed greatly to society (Rhee, 2014). Pasteur’s accomplishments point to singular brilliance and determination of Pasteur's nature. His work aided in developing medicines in areas such as stereochemistry, microbiology, bacteriology, virology, immunology, and molecular biology. Furthermore, his work has safeguarded millions of people from disease through vaccination and pasteurization (Rhee, 2014).
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
Very little is known about the early part of La Fontaine’s life. He was born in Château-Thierry, a small town in the province of Champagne some fifty miles northeast of Paris. His baptism was entered in the parish of Saint-Crépin register on July 8, 1621. Most take this as his actual birth date, but according to the custom of the period, it probably means that La Fontaine was born a day or two earlier. (Mackay, pg.4) He was the son of Charles de la Fontaine, a royal government official who inspected forests and waterways. His mother Françoise Pidoux, who came from a nobler family from Poitou. He also had a younger brother who was born two years after La Fontaine. He also had an older step sister named Anne de Jouy on his mothers side of the family. (Carter, pg. 46)
Pasteur's real world question was; how to create sterile air so that spontaneous generation may be tested. His model was to break a flask in high altitude and then reseal it under a flame while holding it with pincers. His nutrient was a yeast infusion. His hypothesis was, this would create sterile air to test spontaneous generation. His data showed that only one out of 20 became prurient. The data seemed to fit the hypothesis closely. Therefore the model seemed to fit the real world. There were no other models at the time to compare and discuss.
Louis Pasteur was born December 271822 in Dole, France. When he was five, his family moved to Arbois, France. He attended college in Paris and received a Doctor of Science degree in 1847. He began teaching chemistry at the University of Strasbourg, where he met his wife, Marie Laurent, who shared Pasteur’s interest in science. Marie and Pasteur married in 1849 and had five children, two of which survived to adulthood. Pasteur eventually went on to instruct chemistry and became dean of the school of science at the University of Lille.
The debate over spontaneous generation continued for centuries. In 1745, John Needham, an English clergyman, proposed what he considered the definitive experiment. Everyone knew that boiling killed microorganisms, so he proposed to test whether or not microorganisms appeared spontaneously after boiling. He boiled chicken broth, put it into a flask, sealed it, and waited - sure enough, microorganisms grew. Needham claimed victory for spontaneous generation.
