Louis Pasteur

(Dole, France, 1822 – Marnes-la-Coquette, 1895.) French chemist and bacteriologist, founder of microbiology and a pioneer of modern medicine. Since the time of Hippocrates (V century BC) he had attributed various abstract internal disease to imbalances moods of the human body. It was not until the nineteenth century that, with the help of great researchers such as Louis Pasteur and Robert Koch, he firmly established the theory of microbial origin of infectious diseases caused by environmental pathogens that enter the healthy body. The identification of specific causes and  a wide range of conditions marked the beginning of the current scientific medicine. Pasteur gave a decisive impetus to the development of vaccines and is particularly remembered for the success of his vaccine against rabies (1885).

Coming from a family outside medicine, it was only after finishing his basic studies that he would begin an unstoppable career as a teacher and researcher. At 23, he graduated in Sciences in the School of Paris and two years later earned a doctorate.

In 1854, aged 32, he was Dean and Professor of Chemistry at the Faculty of Lille, where he promoted a new initiative by promoting evening classes for young workers. University research and industrial production constituted, for him, an inseparable universe, contributing in the process of production of textiles, food and beverages.

Shortly after, he was summoned as director of Scientific Studies in the School of Paris, and continued his research on fermentation and lactic acids. Despite a stroke that paralyzed half  of his body, Pasteur advanced with the discovery of cures for various infections and established the basic principles of sterilization. Precisely, this process of annihilation of microbes in liquid was recognized as pasteurization.

Subsequently, in 1881, he discovered the experiment –because an English scientist with a very serious disease could be prevented by injecting  the living being with a similar virus less intense. and it gave birth to a  vaccination system  that constituted one of the greatest achievements of mankind.

In 1885, this invention cured rabies, which gave him fame. In June 1887, the French government created a decree at  the institute bearing his name, which then would leave eight Nobel laureates and discoveries as important as, in 1983, the AIDS virus.

Pasteur died in Marnes-la Coquette, on September 28, 1895.
