Louis Pasteur (1822-1895)

Louis Pasteur was born on December 27, 1822, in Dole, France. He received a Doctor of Science degree in 1847. He then taught chemistry at French universities. Pasteur worked on Edward Jenner’s theories and developed vaccines for various disease.

While working at the University of Lille, Louis Pasteur discovered that fermentation involved microbes. In 1856, Pasteur showed that fermentation is caused by yeast not by chemical agents; some years later he showed that similar microorganisms were responsible for causing wine to go sour and beer to deteriorate. Fermentation is a chemical change to make bread, wine, cheese and other foods.
Pasteur left Lille in 1857 to become the director of the Ecole Normale in Paris. Pasteur showed that heat killed the microbes that cause fermentation. This discovery led to his invention of a process for destroying harmful microbes in food. Pasteur is known for developing the process of pasteurization.

On the 14th of November 1888, the ‘Institute Pasteur’ was founded. Pasteur created the first vaccine for rabbles. Thousands of people suffering from bites from rabid animals, from all land, have been treated in this institute and the death rate from this disease has been reduced to less than one percent. He died on September 28, 1895, near Paris
