Louis Pasteur was born in Dole on December 27, 1822. He was a French chemist and biologist.
In 1847 he earned a doctorate at the Ecole Normale in Paris
In 1854 he worked on bacteria. He found that the desired production of alcohol in fermentation is indeed due to the presence of additional organism such as bacteria.
Because he aware of the presence of microorganism in nature, in 1864 Pasteur undertook several experiments to find out where these “germs” came from.
In 1865 he found a method to destroy harmful becteria without materially changing the composition flavor or nutritive value of the liquid. The process was named after him, pasteurization.
Pastuer also determined the natural history of anthrax is caused by particular bacillus. He suggested that animals should be given anthrax in a mild from by vaccinating them with weakened bacilli. This vaccine provided immunity from potentially fatal attacks.
Louis Pasteur contributed so much to public sanitation. He founded the science of microbiology, proved the germ theory of disease, invented the process of pasteurization and developed vaccines for several diseases including rabies.
