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.
Early Years Had a early ambition to become a
teacher. 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.
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.
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.
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.
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
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.

Scientist would still be working on cures that Louis found
