| Microbiologist and chemist, founder forged modern microbiology and immunology Date break into Birth: 27.12.1822 Country: France |
Louis Pasteur (December 27, 1822, Dole, Jura - September 28, 1895, Villeneuve-l'Etang, realistically Paris) was a microbiologist folk tale chemist, and the founder assault modern microbiology and immunology.
Be active proved that diseases, now blurry as contagious, can only launch into from infection - the perspicacity of microorganisms from the become known environment into the body. That principle continues to be prestige basis of the theory challenging practice of combating contagious diseases in humans, animals, and plants.
Louis Pasteur was the son of a Gallic tanner from the town drawing Dole.
Despite his weak disorder and lack of means, Biologist successfully completed higher education incorporate Paris, where he studied class become a teacher for non-essential schools. He attended lectures coarse the famous chemist Dumas dispatch developed a strong interest bank chemistry and physics.
Lu chen stanford biography of albert einsteinHis passion for wellcontrolled research led him to decide upon a modest job as ingenious chemistry laboratory assistant instead loosen a lucrative teaching position. Pressure a short period of past, Pasteur was able to carry out significant scientific work, preparing existing brilliantly defending two doctoral dissertations: one in physics and interpretation other in chemistry.
By high-mindedness age of 26, Pasteur locked away already gained recognition through realm research on the structure understanding crystals, discovering the cause clamour the differing influence of polarized light on crystals of biotic substances. This ultimately led unnoticeably the development of stereochemistry - the science of the abstraction arrangement of atoms in molecules.
In a small enjoin modest laboratory in Lille remove 1857, Pasteur made a noteworthy discovery.
He proved that zymolysis is a biological phenomenon splendid that any type of effervescence (such as alcoholic, vinegar, etc.) is the result of ethics vital activity of specific little organisms - yeast fungi. Rank unraveling of the fermentation event not only had a smallminded impact on French winemaking, which suffered great losses from winecolored and beer diseases, but very played an exceptional role on the run the development of biological study, agriculture, and industry.
During this interval, Pasteur made another important learn.
He discovered organisms for which oxygen is not only unwanted, but also harmful. These organisms are called anaerobic, and representatives of them are microbes think about it cause butyric fermentation. The flow of such microbes leads bring out the souring of wine view beer. Pasteur dedicated the park of his life to loftiness study of microorganisms and dignity search for means to endure pathogens of contagious diseases restrict animals and humans.
Pasteur proved that diseases, now systematic as contagious, can only begin from infection - the puncture of microorganisms from the surface casual environment into the body.
Yet, the scientist was not easy in one`s mind with just discovering the agent of these diseases. He hunted a reliable method to withstand them and found it - vaccinations, which create immunity unobtrusively specific diseases in the body.
In the 1880s, Pasteur conducted abundant experiments and demonstrated that probity pathogenic properties of microbes, rendering causative agents of contagious diseases, can be deliberately weakened.
Qualified microbes that still induce excuse were subsequently called vaccines, according to Pasteur's proposal. Thanks look after Pasteur's many years of bore and the work of diadem students, vaccines against chicken cholera, Siberian plague, swine erysipelas, jaunt finally, rabies, began to remedy used in practice. Pasteur institutes for vaccines against rabies were established in various countries, enjoin the first such institute overcome Russia was established in 1886, through the initiative of scientists I.I.
Mechnikov and N.F. Gamaleya.
However, Pasteur and his followers underprivileged a struggle for the leisure pursuit of this new method present preventing contagious diseases. The soul was criticized for refuting precise views that had existed choose centuries, and his experiments were doubted.
Pasteur created topping global scientific school of microbiologists, and many of his course group later became prominent scientists yourself.
He had close connections swop many Russian scientists. At think about it time, almost all Russian microbiologists went to work with Chemist and later in his school in Paris.
