Louis Pasteur And His Voyage In Saving Man

2630 words - 11 pages

Many people take for granted the knowledge and findings of those that have made our lives easier. Ungrateful to those that have devoted their lives to saving others through scientific findings. Those scientists who have collaborated to the discovering of diseases and finding vaccinations, are people that quite a few do not know about and in some cases are unaware that these people ever existed. Louis Pasteur had one of those prestigious minds that millions are indebted to for his findings and research. Pasteur, the French scientist of the late 1800’s devoted his life to save millions. His teachings and his researched work are those of inspiration, even to this very day. Of his several ...view middle of the document...

Soon the task of finding a way to get rid of the pathogen was brought to Pasteur’s attention. After constant trial and errors, Pasteur made it possible to kill the pathogens by applying heat to the fermentation process, which resulted in a complete success. The process of applying heat is now recognized as Pasteurization, and is still used to this day to rid the excess pathogens in the substances we drink such as milk, wine and beer. Without the creation of Pasteurization, millions of people would die due to the putrefaction of milk and alcoholic beverages.
As Pasteur generally approached everything in his life with great focus and the dedication to solve the riddling puzzles of his time, he continued studying fermentation. Pasteur soon came across butyric fermentation. He noticed that it produced an acid with a nauseating smell that gave off carbon dioxide and hydrogen at the same time (Cuny 81). Pasteur began to study the substance under microscopic provisions and found yet another organism that was caused by bacterium. He had discovered a new form of life, one of anaerobiosis, defined as life sustained by an organism in the absence of oxygen (American). From studying this organism, Pasteur concludes that organisms, such as bacteria, live in our surroundings and are the causes of diseases. In many cases, bacteria can kill other organisms and other bacteria can cure organisms by destroying the pathogens that are already present within the organism. With the idea that life can be sustained with the absence of oxygen, lead to one of Pasteur’s well renowned studies that effectively disproved a belief that was very well known during his time: spontaneous generation.
Where does life come from? About a hundred and fifty years ago everyone, as well as the most educated scientists, believed that it was due to the phenomena called spontaneous generation, “the expression, proving that life could be generated by inert matter” which at the time was a well-known and respected theory (Eastman 155).
This has been believed once. Diodorus Siculus, in the first century B.C., asserted that the mud of the Nile, when “sufficiently warmed,” brought forth animals “of enormous size.” Ambroise Paré who declared that “toads were born of the moisture of rocks and stones”; Van Helmont, that “mice can be produced by a woman’s dirty shift.” (Cuny 88)
Pasteur was sure that these beliefs were false and set out to prove his theory of life, which according to Cuny entailed that life can only be born from life and more precisely, that new individuals could only be born from one or two parents of the same species. Pasteur concluded with the hypothesis that in the air of our surroundings germs and bacteria existed. The living particles in the air explained the bacteria he found in butyric fermentation. Now the complication he faced was to prove his findings to those who firmly believed in spontaneous generation. However, how was Pasteur going to...
