The document outlines the life and accomplishments of Louis Pasteur. It discusses his childhood in France, early interests in art rather than science, and key scientific explorations and discoveries around crystallography, fermentation, pasteurization, vaccines for anthrax and rabies, and silkworm diseases. Pasteur's work revolutionized chemistry, microbiology and public health.

4. Childhood  Lived on rue des Tanners,
“the street of the tanners.”
 Moved to Marnoz, France at
two.
 In 1827 the family settled in
Arbolis, France.
 Had three sisters.
 Was an ordinary student.
 Had no interest in science.
 Showed great skills in art,
drawing and painting.

5.  Had a early ambition to become a
teacher.
Early Years  Went to Paris at 16 to Ecole Normale
Superieure, it was 250 miles away
from home. He only lasted a month.
 Went to a college in Besancon, it was
only 25 miles away.
 Went back to Pairs and lived at a the
Barbet boarding school.
 He was a teacher and a student.
 Louis Pasteur thought that the
chemistry professor, Monsieur Jean-
Baptiste Dumas was a great lecturer
and he though that what he talked
about was very interesting and
exciting.
 Before turning 21 he entered the Ecole
Normale Superieure to learn how to
teach chemistry and physics.

6.  When he started, scientist
only knew about the shapes
of crystals and that some
crystals bent light.
 He wondered why only
some crystals bent light.
 He wondered if the reason
was because the material and
shape.
 He began by studying
tartaric acid and tartrates.
 In the end of the study of
crystals there was only one
difference. The difference
was in the slop facet F. One
goes in one direction only
and the other goes in both.

7.  Monsieur Bigot asked Louis Pasture
for help.
 Changing beet sugar into alcohol.
 Some vats weren’t turning into
alcohol but turning sour.
 Took some good and bad liquid to
study under a microscope.
 Realized there was yeast cells
present when beet sugar or grapes
fermented. He didn’t know why
they were present.
 He became convinced that they
caused fermentation. Fermentation
is the breaking down of certain
material by microorganisms.
 Found that the good liquid did not
have black rods, the bad liquid had
black rods that there multiplying.

9.  Discovered in 1863
 Napoleon the 3rd asked Louis
Pasture to help wine makers
 Done by heating wine or beer
to a heat above 135°F so the
germs die and the wine will
last longer.
 Heat is used to kill microbes
in drinks such as beer and
wine. It is used in milk and
juice too.
 This discovery saved a wine
industry in France.
 This teqniqe is named after
pasture, Pasteurization.
 Without pasteurization wine
and other foods would
become sour and spoil.

11.  Found it out while finding
a cure of anthrax .
 Done by giving 25/50
sheep a vaccine and seeing
if the ones that were given
the vaccine didn’t die.
 First tested on a boy who
had been bitten by a rabid
dog 9 times.
 The results were successful.
 Louis pasture is better
known for curing rabies
than anthrax

12.  His friend invited him to study the
epidemic killing the silk worms from a
silk industry .
 The disease starts at the surface of the silk
worm.
 The disease looked like small grains of
pepper .
 Louis Pasture thought that the little
grains caused the disease.
 Louis Pasture thought it was the
diseased moth producing diseased eggs.
 The experiment he did to get the answer
was to check the moth after they laid
eggs. If the moth had any grains, the
eggs were sure to be diseased. If not, then
the worms would be healthy.
 Louis waited to see if he was right, but
the answer was disappointing .
 He went back and saw that there was not
one disease but two diseases
 The second dieses was the microbes
spreading.

14.  Thanks to pasteur are not
many diseases
 Chemist sees the world
differently
 Less people suffer from
diseases
 Without him many people
would be dead do to
diseases
 Scientist would still be
working on cures that Louis
found
