Free Essays on Louis Pasteur

Louis Pasteur Louis Pasteur was an example of a truly gifted person who made many wildly diverse discoveries in many different areas of science. He was a world-renowned French chemist and biologist whose work covered the way for branches of science and medicine such as stereochemistry, microbiology, virology, immunology, and molecular biology. He also proved the germ theory of disease, invented the process of pasteurization, fermentation, and developed vaccines for many diseases, including rabies. Pasteur was born on December 27, 1822 in Dole, France, and grew up in the small town of Arbois. As a young boy, Pasteur showed no particular interest in science. His talents were mainly drawing and painting. During his youth, he developed an ambition to become a teacher. During his studies to become a teacher, a chemistry professor, Monsieur Jean-Baptist Dumas, fascinated him. He decided that he wanted to learn to teach chemistry and physics, just like his favorite professor. (Debre, P. Louis Pasteur.) In 1847 he earned a doctorate at the Ecole Normale in Paris, with a focus on both physics and chemistry. Becoming an assistant to one of his teachers, he began research that led to a significant discovery. He found that a beam of polarized light was rotated to either the right or the left as it passed through a pure solution of naturally produced organic nutrients, whereas when polarized light was passed through a solution of artificially synthesized organic nutrients, no rotation took place. If bacteria or other microorganisms were placed in the latter solution, then after a while it would also rotate light to the right or left. From this, he concluded that organic molecules exist in one of two forms, â€Å"left-handed† or â€Å"right-handed† forms. After spending several years researching and teaching at Dijon and Strasbourg, Pasteur moved in 1854 to the University of Lille, where he became the professor of chemistry and dean ... Free Essays on Louis Pasteur Free Essays on Louis Pasteur Louis Pasteur: Greatest Achievements Louis Pasteur was one of the most important scientists of our time. The foundation of our knowledge about health and disease comes from the discoveries of this one man. He made many discoveries and solutions for problems of the every day life that are still in effect today. Pasteur was born on December 27, 1822 in a little town called Dà ´le in the foothills of the Jura Mountains of eastern France. When he was five years old his family moved to Arbois where he grew up with his father, mother, and three sisters. While attending primary school Pasteur was only an average student. Some considered him to be slow because he worked so hard on an exercise problem to make sure that he had the right answer. While in high school Monsieur Romanet, Pasteur’s principal, became interested in Pasteur and began to help him with his studies. With this encouragement Pasteur became a very good student. The principal suggested that he aim to attend Ecole Normale in Paris where he could become a professor at one of the great universities, however his father felt that this was far-fetched and preferred that Pasteur attend a more local school (Burton, 5-7). Although his father had other plans for him, Pasteur had the opportunity to attend a preparatory school in Paris before going on to Ecole Normale, however when he got to Paris he became very homesick and his father soon arrived to take him home. After returning to Arbois Pasteur attended a local school named Besancon where he worked very hard and became one of the top students in his class. In 1842 Pasteur passed the admission tests to attend Ecole Normale however he was rated fifteenth of twenty-two candidates and this was not good enough to satisfy him. He continued to study and finally in 1843 Pasteur sailed through his admission tests and was awarded fourth place among the other candidates (Burton, 7-11). Although Pasteur is sometimes considered to be th... Free Essays on Louis Pasteur LOUIS PASTEUR There is a time in every man's life when he looks to his God, when he looks at his life, when he wonders how he will be remembered. It can happen with age or with tragedy or closeness of death. I am lying here at age 45, not able to feel my left side. Not knowing if this stroke that has befallen me will end my life before the mysteries that I have unlocked can be resolved. I have asked God throughout my life to be able to "...bring a little stone to the frail and ill assured edifice of our knowledge of those deep mysteries of Life and Death where all our intellects have so lamentably failed." (Vallery-Radot, 88) Death is more familiar to me than I care to think... three of my daughters.. .my father.." I have been thinking all day of the marks of affection I have had from him. For thirty years I had been in his constant care, I owe everything to him. When I was young he kept me from bad company and instilled into me the habit of working and the most loyal and best filled life. He was far above his position (tanner) both in mind and in character. The touching part of his affection for me is that it was never mixed with ambition...and yet, I am sure that some of the success in my scientific career must have filled him with joy and pride..."(Vallery-Radot, 119) Science...it is my life..it has brought me a deepness of pleasure that I have always known yet never realized. I remember when I was working on the tartrates, tartaric acid and racemic acid or paratartrate. Tartaric acid was known to rotate light to the right, whereas paratartrate, odly enough, did not affect light in the least. "The fortunate idea came to me to orient my crystals with reference to a plane perpendicular to the observer, and then I noticed that the confused mass of crystals of paratartrate could be divided into two groups according to the orientation of their facets of symmetry. In one group, the facet of symmetry nearer my body was inclined to my r...
