Louis Pasteur was born in Dole, France. His parents knew little of the incredible impact he was to have on medicine and public health. The baby they held in their arms was to save millions to follow.
Pasteur was an average student in his early years, but in 1839 was admitted to the College Royal at Besancon to study philosophy. In his years there he earned a bachelor's degree (1940). He was also later appointed a tutor of mathematics there. He also entered Ecole Normale Supreiere in 1843.
In 1854 he became dean of the science faculty in the University Of Lille, and it was here that Pasteur made his most famous discovery. A local wine manufacturer, M. Bigot, sought from Louis a solution to the souring of his beetroot alcohol. Pasteur soon wrote a paper on lactic acid fermentation and discovered the detrimental effect of germs on beer fermentation.
Following his fermentation discovery, Pasteur defied the theory of spontaneous generation. This theory did not encompass his germ theory and in a battle of experiments Pasteur emerged victor. he essentially proved that microorganisms cannot grow without contamination.
Pasteur also pioneered immunology and vaccination against chicken cholera, rabies and swine erysipelas. He inoculated the chickens with a weaker strain of the disease and discovered they became immune to it. He used this to fight the other aforementioned diseases.
Louis Pasteur suffered a stroke in 1894 which severely impaired his health. Never fully recovering from this, he died September 28 in 1985. He was buried in the Cathedral of Notre Dame.
