The example of legend short story French chemistry and biologist Louis Pasteur is generally acknowledge to be the most important single figure in the history of medicine laster made many contribution to science but he is most famous for his advocacy of the green theory of disease and for his development of the technique of preventive inoculation. Pasteur was born in 1822,in the town of dole , in eastern France .example of legend short story As a college student in Paris ,he studied science .His genius was not evident during his student days I’m fact one of his professor recorded him as”mediocre” in chemistry.However ,example of legend short story after receiving his doctorate in 1847, Pasteur soon showed that his professor judgment dah been in error .His research on the mirror image isomers of tartaric acid made laster a renowned chemist when he was only twenty six years old .He then turned his attention to the study of fermentation ,and showed taht process is due to the action of certain types of mieroorganism.example of legend short story ,
He also demonstrated that the presence of certain other species of microorganisms could produce undesirable products in the fermenting beverages.This soon led him to the idea that some species of microorganisms could produce undersirable product and effects in human beings and other animals.pasteur was not the fast person to suggest the germ theory of disease.Similar hypothesis had been advanced earlier by girolamo fracastore friendrich championship of the green theory,example of legend short story sibstantiat by his numerous experiments and demonstration,that were the principle factor in convincing the scientific community that the theory was correct.If deases were caused by germs,it seemed logical that by preventing harmful from entering the human body, diseases might be avoided.Posture therefore stressed the importance of antiseptic methods for physicians and he was of antiscptic methods for physicians and he was a mojor influence on Joseph Lister who indroduced antiseptic methods into since of infection.When he was in his mid fifties ,laster turned his attention to the study of anthrax ,a serious infectious disease which attacks .Cattle and many other animals, including human being.pasteur was able to show that a particular species of bacterium was responsible for the discase of for greater importance, however was his development of a technique for producing a weakened strain of the anthras bacillus.Injected into cattle,this weakened strain produced a mild form of the disease, while was not fatal but which enabled the cattle to devoloped an immunity to the normal form of the disease .
Pasteur’s public demonstration of the effectiveness of his technique in immunizing. Cattle against anthrax aroused great excitement.It was soon realized that his general method might be applied to the prevention of many other communicable diseases.Pasteur himself,in his most renowned single achievement, developed a technique for inoculating people against the dreaded diseases of rabies.Other scientists, applying Pasteur’s basic ideas, have since developed vaccines against many other serious disease,such as epidemic typhus and pollomyelitis.pasteur,who was an unusually hard workers, has a variety of lesser but still useful achievement to his eredit.It was his experiments,more than any othery,which convincingly demonstrated that microorgams do not arise through spontaneous generation.pasteur also discovered the phenomenon of anacrobiosis ;
that certain microoganisms can live in the absence of Any air or free oxygen. Pastures work on disease of silkworms has been of great commerical value.among his other achievement was the development of a vaccine for the prevention of chicken cholera,a disease that attacks fowl Pasteur died in 1895,near Paris.A comparison is often made between pasture and Edward Jenner ,the English physician who developed a vaccine against smallpox. Thought Jenner’s work was done more then eighty years before Pasteur’s,I consider Jenner much less important because his mithod of immunization worked for only one disease whereas pastures method could be and have been applied to the prevention of a large number of disease. Since the mid_nineteenth century,life expectancies in much of the world have fought doubled .This enormous increase in human life spans has probably had a greater effect on the lives of individual human being than has any other development in the entire history of the human race.In effect,
modern science and medicine have presented each of us now living with virtually a second lifetime.if this increase in longevity could be solely at tributed to the work of Pasteur,I would have had no hesitation at all in placing him fast in this book . Nevertheless, Pasteur’s contribution are so fundamental that there is no question that he deserves the larger share of the credit for the decline in death rates taht has occurred in the last century,and that he is therefore assigned a high place on this list.
