2. Louis was born on 27th December 1822, in
Dole, France.
His father's name was Joseph.
He was a soldier in Napoleon's army and his
job was a gravedigger.

3. • Louis' wife was Maria Laurent. They got
married in 1849. They had 4 children, two of
them died in the childhood. Louis Pasteur was
a great patriot and a good Catholic.

4. As a child Louis loved to paint.
His paintings were amazing.
But at the age of 19, he decided to start
a scientific career.

5. He finished school in Besançon. Then he studied in
Paris École Normale Supérieure. He studied physics
and chemistry. In the course of his study, he was not an
extraordinary student. In 1846 he received a Ph.D.
in chemistry.

6. He worked as a professor at the University of
Strasbourg, Lille and Paris.

7. He made the first discovery in 1848 in the field
of crystallography. Using the glass and
tweezers, Pasteur carried out the
observation of crystals tartrates. It
showed that there were two of the characters,
which were their mirror reflections. In this way, Louis
discovered the secret construction of tartratic acid.

8. In 1854 Pasteur concentrated on the fermentation process.
Other famous chemists believed that the fermentation was a
chemical process. Louis denied it. He came to conclusion
that it was a biological process, during which yeast was
reproduced. Louis published his conclusion in his book in
1857.

9. During studies on fermentation Pasteur concluded
that: 'there is a category of creatures that breathe
so actively that receive oxygen from certain
compounds, which are subject to the
slow decomposition'.
Pasteur discovered anaerobic micro-organisms
and gave scientific basis for the process used for
centuries, for example in the manufacture of wine,
beer and strong alcohol.

10. Luis undertook many highly
innovative experiences. Thanks to them, he
showed that atmospheric air contains micro
organisms and that can also be found in substances
such as sugared water, which comes into
contact with the air. He heated and boiled water in glass
flasks with curved neck. It turned out that life
appears in the flasks in the liquid, until the contact with the air.

11. Louis explained the causes of spoilage of wine turns into a vinegar or
bitter. He proved that this process was the result of bacterial
decomposition. He wanted to remedy this by adding variety of forms to
the wine. He discovered a better way to do this. Since then, the process is
called pasteurization.

12. In 1880 Louis managed to isolate the microbes that cause cholera in
poultry . It was the first attempt to induce immune reaction. He wanted to
manufacture the vaccine. Pasteur state birds of a culture of cholera
bacteria. He concluded that the birds did not fall ill. Then, he carried out a
further experiment, which showed that the activity of cholera germs were
weakened with the progress of time. Pasteur discovered the general
principle of the acquisition of resistance by organisms.

13. Then, the vaccine against rabies was
developed. Up to that time, the disease was
considered to be terrible and almost incurable.
Pasteur immunized his dogs after implantation
of the weakened bacteria.

14. In 1885 a small boy, who had been attacked by the
dog affected with rabies, was brought to Pasteur.
The scientist decided to use the vaccine. Pasteur
saved the boy and covered himself with honour.

15. He died in St. Cloud on 28th September
1895. He was buried in the Cathedral of
Notre-Dame in Paris. Currently, the
remains of Louis Pasteur are stored in the
crypt in the Pasteur Institute of Paris.
