Louis Pasteur: Leading French Scientist
Louis Pasteur was a French scientist who made discoveries that were of great importance in both chemistry and medicine. It was he who created the technique known today as pasteurization.
Short biography, discoveries and main studies
He was not a prominent student until he transferred to the Higher Normal School in 1843. He graduated and had access to the classes of a great French chemist named Jean Baptiste Dumas. From then on, he became interested in chemistry.
His interest in chemistry was so great that he soon became a professor of chemistry in Strasbourg and some time later in Paris.
In 1848, he made a discovery about tartaric acid dimorphism while observing under the microscope the astonishing symmetry presented in both types of racemic acid crystals.
At only 26 years old, Pasteur made a discovery about the deviation in the plane of polarization of light that earned him the grant of the French Legion d'Honneur. "
Some time later, he complied with some of the region's winemakers and brewers who asked him to find out how the wines and beers soured.
During his investigation, using a microscope, he found that the yeast caused this process. It solved this problem through a process that originated the current technique of pasteurization of foods.
From this new discovery, it was found that in both fermentation and organic decomposition processes, there is the action of microorganisms.
In 1865, its discovery was used by surgeon Joseph Lister, who used Pasteur's knowledge to eliminate microorganisms present in wounds and surgical incisions.
In the year 1871, Pasteur insisted that all doctors in military hospitals adopt this technique on all medical procedure instruments.
In his "germ theory of infectious diseases," this leading chemist and researcher argues for the idea that every infectious disease has its cause in a microorganism that can spread among people. According to him, one must identify the causative microbe of each disease to find a way to combat it.
His intense studies on the life of pathogenic microorganisms led him to find a way to fight them, and it was from then on that he discovered vaccines, including anti-rabies.
The Pasteur Institute was founded in 1888 by Louis Pasteur himself. Today, this institute is one of the most famous research centers today.
