Louis Pasteur: biography, who he was and what he invented

The importance of Louis Pasteur in the world of science is very remarkable. This French chemist and bacteriologist has left us a really important legacy and his discoveries have made it possible to stop some diseases, among many other things. This scientist is known for developing the vaccine against rabies and for being the father of microbiology, among Many others.Brief biographyThe chemist Louis Pasteur was born on December 27, 1822 in Dôle, Burgundy, (France), and died on September 28, 1895, at the age of 73, in Marnes-la-Coquette, (France) . He received his doctorate in Physics and Chemistry from the École Normale de Paris and began working for various departments and practiced his life as a researcher.Findings and inventions for science Among his various inventions for science, it should be noted that from a very young age, with 23 years , discover the optical activity of space isomers; When he examined tiny crystals of salts formed from tartaric acid synthesized in the laboratory under the microscope, he saw that there were crystals of two different types. Then he also discovered pasteurization that was applied in various fields such as food. He applied some of the principles of chemistry and fermentation to end some diseases. And this is how the microbial theory of the disease appeared. Investigating it, he discovered some vaccines and in 1885, he administered a vaccine to a young man who had been bitten by a dog with rabies. So he was the discoverer of the rabies vaccine that still persists today.At science and medicine level, his other findings were determined antibiotics, sterilization and hygiene as effective methods of cure and prevention against the spread of infectious diseases.And the study of infectious diseases with the search for a germ that causes each disease to find a way to combat it. Publications and laboratory notebooks He made a variety of publications that saw the light in life, but also told the family not to show their lab notebooks to anyone. As early as 1964, the last surviving male descendant of the scientist, Pasteur Vallery, handed over the laboratory notebooks to the National Library of France, a total of 144 notebooks, 42 of them newspaper clippings, class notes, etc. while the remaining 102 correspond to real laboratory notes and 40 annual research documents. He died at the age of 73 in Marnes-la-Coquette (France) due to cardiorespiratory arrest.
