LOUIS PASTEUR
Chemist and Biologist
December 27, 1822 - September 28, 1895
Louis Pasteur was born to a tanner, Jean Joseph Pasteur and hiswife Jeanne in France in the ancient town of Dole. His father had been a soldier in Napoleon's army.
Pasteur went to the Royal College in Besancon where he earned his B.A. and then a Bachelor ofScience degree two years later at the age of twenty. In 1847 he received a doctorate degree and became a professor at age twenty-six.
He began to study fermentation and how it related to alcoholicdrinks. His research led to the process of pasteurization of milk to kill viruses and harmful bacteria. The milk is not heated to the boiling point which would change the flavor, but is heated to atemperature sufficient to kill the bacteria which would cause it spoil easily or cause disease. It is then chilled and must be kept cold until used.
He named the new science bacteriology and suggesteda new theory, The Germ Theory of Disease. He believed that diseases were caused by germs attacking the body from the outside.
The raising of silkworms was a large industry in France at that time.People raised them in their homes or in large sheds. In 1849 the worms were hit with a disease and began to die. It first started in France and spread worldwide to every country except Japan. In 1865at the request of the government Pasteur performed experiments to find the cause of the malady. Using the microscope he determined that corpuscles in the infected worms were causing them to die. Theworms would infect each other. He helped the growers to find a way to isolate and then use eggs that were not infected.
At the end of this arduous task he suffered a stroke and paralysis. Forseveral months he was completely paralyzed. He was only 45 years old. After two years he began to recover the use of his body.
His next task was to try and find the cause of disease in the body. He...
