Study About Louis Pasteur
Louis Pasteur
Louis Pasteur was born in quite humble circumstances, at Dole
in the Jura District of France in 1822. At Arbois, he attended communal college
where at first he did not show any interest in studies but later grasped his
mistake and set himself in earnest at school. His family shifted to Besancon,
from where he graduated and later on taught there. Pasteur was not a serious
student in the beginning. He was fond of making sketches of his friends and
enjoyed fishing. Later, he realized the importance of time and money and proved
himself a bright student.
Chemistry was Pasteur’s favorite subject. He asked his
teacher some unanswerable questions. The teacher discouraged him by saying that
only the teacher had the right to ask questions. Pasteur’s love for France was
so intense that he tried to enroll himself twice in the National Guard despite
his physical incapacity. He offered all his worldly wealth for the country. His
work on brewing proved very beneficial for France. He returned his Honorary
Degree of Medicine to Germany when it attacked France.

Spontaneous generation means the production of living things
from non-living. Pasteur proved it a wrong Concept. He claimed that if a
substance is sufficiently heated, no bacteria would be produced in it. In 1860,
the French Academy offered a prize for the solution of problem whether
spontaneous generation was or was not a fact. Pasteur claimed that if was a
wrong concept. Pasteur proved that if a substance be heated to destroy all life
in it and if the air in contact be filtered, then bacteria so not develop in
it.
Keeping of silkworms was one of the chief home industries of
France. Every family set aside the best room for rearing and tending of silk
worms. Their common greeting was, “How are your silk worms doing?” instead of,
“How are you?” Pasteur dis covered the causes of the silk disease and suggested
its cure.
Pasteur cultivated the Anthrax germs in such a way that they
became weak. He injected them into the body of an animal suffering from
Anthrax. The animal developed a slight form of disease first but recovered. He
found out that the method protected the animal from the deadly form of the
disease.
Pasteur proved that diseases are caused by germs and germs
can be killed. The fame got by Pasteur motivated other scientists to try
similar methods of cure other disease. In just ten years from 1880 to 1890,
they discovered the germs of consumption, diphtheria, typhoid, lock-jaw,
cholera and Malta fever.
