Louis Pasteur Biography 

Louis Pasteur contributions

French chemist and microbiologist, Louis Pasteur was born on 27th December 1822 in Dole, France to Jean-Joseph Pasteur and Jeanne-Etiennette Roqui. He was a renowned for his findings of the pasteurization, principles of vaccination, and microbial fermentation especially remembered for his outstanding discoveries in the causes and prevention of diseases, and these discoveries have saved uncountable lives ever since. Pasteur has not only decreased mortality from puerperal fever he was one to create the vaccines for rabies and anthrax. His medical discoveries has provided direct support for the germ theory of disease and its use in clinical medicine.

Louis Pasteur Pasteurization

Louis Pasteur Pasteurization

He is popularly known to the general public for his invention of the method called pasteurization where milk and wine is used to stop bacterial contamination. Together with Ferdinand Cohn and Robert Koch, Pasteur is regarded as one of the three main founders of bacteriology and is also popularly acknowledged as the “father of microbiology”.

In his early years of student, he was considered to be an average student who was not particularly interested in academic but rather his interests were fishing and sketching. The pastels and portraits of his parents and friends which he made when he was 15, were later kept in the museum of the Pasteur Institute in Paris. He married Marie Laurent on May 29, 1849. The couple has five children, two of whom only survived to adulthood while the other three died of typhoid. These misfortunes were his motivations for curing infectious diseases.

Louis Pasteur experiment

Pasteur was the one responsible for disproving the doctrine of spontaneous generation where he conducted experiments which showed that microorganisms could not develop without contamination. With the support of the French Academy of Sciences, he showed through an experiment that nothing ever developed in sterilized and sealed flasks but at the same time in sterilized but open flasks microorganisms could grow, winning him the Alhumbert Prize of the academy.

Germ theory of disease

Even though Pasteur was not the first to suggest the germ theory, he proved it and conducted experiments which evidently showed its correctness and was able to convince most of Europe that it was true. Today, he is often considered as among the fathers of germ theory.

Pasteur also made significant discoveries in chemistry, most particularly on the molecular basis for the asymmetry of certain crystals and racemization. His investigation of tartaric acid early in his career, resulted in the first resolution of what we now call optical isomers. His work established our current understanding of a fundamental principal in the structure of organic compounds.

Till his death in 1887 he was the director of the Pasteur Institute, established in 1887. His body even lies beneath the institute in a vault covered in drawings of his accomplishments in Byzantine mosaics. From the beginning of 1868, Pasteur was frequently stricken by strokes, and the one in 1894 severely impaired his health. In 1895 failing to fully recover, he breathed his last near Paris. He was given a state funeral and was buried in the Cathedral of Notre Dame, but his remains were reinterpreted in a crypt in the Pasteur Institute in Paris, where the crypt is engraved with his life-saving works.
