Louis Pasteur

Louis Pasteur

Was a French chemist and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is remembered for his remarkable breakthroughs in the causes and preventions of diseases, and his discoveries have saved countless lives ever since. He reduced mortality from puerperal fever, and created the first vaccines for rabies and anthrax.

Louis Pasteur began his studies at the College of Arbois and here he discovered his talent for painting. He then moved to Paris, but soon returned to Arbois, because he was very disappointed of the artistic experience he had in Paris. He took his baccalaureate at Collège Royal de Besançonin 1840 and in 1842 he acquired another one in mathematical sciences from Dijon and finally in 1843 he was admitted to the “ÉcoleNormaleSupérieure” in Paris, finishing his studies in 1847, when he sustained two thesis, one in chemistry and the other one in physics.

He did a lot of scientific research in the field of crystallography and thus, he discovered the phenomenon of isomerism. He was appointed professor at the Faculty of Sciences in Lille, and here he has made a major discovery, showing that the yeasts are living beings which lead to the fermentation process.

Pasteur’s research also showed that the growth of micro-organisms was responsible for spoiling beverages, such as: beer, wine and milk. With this established, he invented a process in which liquids such as milk were heated to a temperature between 60 and 100 °C. This killed most of the bacteria and moulds already present within them. Pasteur and Claude Bernard completed the first test on 20 April 1862. Pasteur patented the process, to fight the “diseases” of wine, in 1865. The method became known as pasteurization and was soon applied to beer and milk.

In 1880, Louis Pasteur begins his research on bogs. The scientist discovers that the dry spinal cord of an infected animal might prevent this serious disease.After several attempts to develop a concoction with vaccine quality and after many hesitations as well, he then made his first attempt in the case of a child who was bitten by a rabid dog. Three months after starting the first series of injections, the child was saved.After this moment, the Academy of Sciences of France decided to establish an institution which addressed to the rabies treatment. This institution will becomein time the famous Institut Pasteur.

The feature of benefactor of mankind was unfairly not assigned to Louis Pasteur, its discoveries over time being more than useful. His studies and discoveries are serving nowadays to several branches of medicine and science such as: stereochemistry, microbiology, bacteriology, virology, immunology and molecular biology. His work has saved millions of ill people, which is due to vaccines and pasteurization (a method of preserving food, especially the liquid ones, invented by Louis Pasteur).

Pasteur was frequently stricken by strokes beginning from 1868, and the one in 1894 severely impaired his health. Failing to fully recover, he died in 1895, near Paris. He was given a state funeral and was buried in the Cathedral of Notre Dame, but his remains were reinterred in a crypt in the Pasteur Institute in Paris, where the crypt is engraved with his life saving works.
