1822-1895 Louis Pasteur
French chemist and biologist Louis Pasteur, generally considered topnotch bin ace in the history of medicine. Pasteur contribution is presenting many important thoughts for the benefit of science. But the most prominent on him is his opinion of the bacillus theory of disease and the development of prevention techniques through injection.
Pasteur was born in Dole in 1822, the eastern part of France. As a student in Paris he deepen science. His genius is not visible when a student even one of the Grand Masters Pasteur considers "moderate" course in chemistry. Only after he obtained his PhD in 1847, Pasteur proved wrong greeting major professors. Investigation of the treaty acid (tartaric acid) on the glass lift in rank to level chemist famous when he was only twenty-six years.
Then he turned his attention to the investigation of the fermentation and prove that this process is exactly similar process occurs in other micro-organisms can memprodusir results are not desired in terms of fermentation beverage. This opinion soon led him another kegagasan that sort of micro-organisms can also produce things that are not expected and can bring good effect on humans and animals.
Pasteur was not the first to memasalahkan theory of disease bacillus. Similar hypotheses have been developed first by Girolamo Fracastoro, Friedrich Henle and many others. However, Pasteurlah most prominent in terms of the germ theory of disease demonstrated through a series of experiments and demonstrations which is a major factor and convince people that his theory is correct intelligentsia.
If the disease is caused by a bacillus, it seems plausible that by preventing the entry of the bacillus into the human body, the disease can be avoided. Because it emphasizes the importance of Pasteur antiseptic method for the doctors, and he had a major influence on the Joseph Lister introduced antiseptic way into the field of surgery.
Harmful bacteria that can enter the human body through food and drink. Pasteur developed a technique (usually called pasteurization) to destroy micro-organisms in beverages. This technique, if practiced, can destroy pests contaminated milk as a cause of infection.
When approaching the age of mid fifties, Pasteur again switched his attention to the investigation of animal disease bacillus, a kind of serious infectious diseases that attack livestock and other animals, but not humans. Pasteur was able to show that something similar bacillus was the cause of disease. Other more important works is the development of techniques to produce patterns of livestock disease bacillus that has been attenuated. By the way cattle are injected into the body, which has been attenuated bacillus disease can cause a mild illness and do not result in fatal allowing the cattle acquire immunity to face the normal disease. Demonstration Pasteur in public on the effectiveness of the technique immunize animals from livestock disease bacillus cause uproar. Soon realized that the general method can be used for all manner of disease prevention community.
Personal discovery of Pasteur's most famous is the development of techniques to prevent injection of human rabies dreaded disease. Other scientists, to mimic the basic idea Pasteur, since it develops a vaccine to prevent other serious diseases such as typhoid and poliomyelitis.
Pasteur, who likes a lot of excellent work, creating inventions are less important but still useful for the fragrance name. Is none other than the sense of discovery discovery --more than enough spare ones that conclusively demonstrate that micro-organisms do not grow through breeding. Pasteur also discovered anaerobiosis phenomena, such as micro-organisms can live in something in the absence of air or oxygen. Pasteur's work on silkworm disease brings a high commercial value. Another discovery is the development of a vaccine to prevent cholera outbreaks in chickens and diseases that attack poultry. Last breath Pasteur near Paris in 1895.
People often make the comparison between Pasteur by Edward Jenner, English physicist who developed a vaccine for the prevention of smallpox. Although Jenner did it 80 years before Pasteur, I consider the significance of Pasteur Jenner is not, because the immun system applies only to one type of disease course, while the system can Pasteur has proven-- powerful --and to immunize against many diseases.
As from the mid-19th century, world population needs to grow almost twice hpat. Added requirement absurdly rapid and wide-reaching range is more powerful than anything that ever happened in the history of mankind. As a result, modern knowledge and the medical world we actually have to present the second period of life. If the addition of this extra term can be solely attributed to the work of Pasteur efforts, I did not hesitate and falter again put on the first level in this list. However, donations Pasteur so fundamental that there is no question that Pasteur had a large share in terms of preventing mortality at the end of this century. And because it's worth Pasteur placed higher in the order of the book list.
