2. Early & Personal Life The French Chemist, Louis Pastuer was born on December 27th 1822, in Dole, France. He was raised in a town called Arbois. He achieved degrees in Letters and Mathematical Science before he got into an elite university called EcoleNormaleSuperieure. Before becoming a professor of chemistry at the University of Strasbourg, he briefly taught physics at Dijon Lycee. When teaching chemistry, Louis met the University’s rector’s daughter with the name of Marie Laurent, he married her on May 29th 1849 and had 5 children, two of his children died as kids because of a disease called Typhoid, these unfortunate events inspired Pastuer to start finding cures for diseases.

3. Pasteurization • Louis studied fermentation, his research drove to the procedure of pasteurization of milk to get rid of viruses and negative bacteria. • The milk is not heated to point that is would change its flavor, it is heated to a temperature high enough to just kill the bacteria that would eventually cause the milk to spoil or give diseases. • After that the milk is then kept cool until it’s used.

4. Pastuer and Rabies • Pastuer is famous for his work on vaccines for Rabies, which is a particularly contagious disorder that strikes the body’s central nervous system. It gains access to the body through the bite of an infected animal or through infected saliva going into an existing cut. Before Louis concluded that the disease was set in the central nervous system of the body, he did some experiments with the saliva of this animals that were aching from the disease. After studying the tissues of infected animals Pasteur was able to produce a narrowed form of the virus, that could be used for vaccination.

5. Testing on Man • On July 6 1885, Pasteur tested his rabies vaccine on human for the first time. He tested it on a young man called Joseph Meister and eventually saved his life, Joseph had been bitten by a dog who suffered from rabies. Pasteur was very eager to treat him with his new treatment. His method went on for 10 days and finally Joseph recovered from his disease and stayed healthy. Since then thousands of peoples’ lives had been saved because of this discovery.

6. How Pasteur has affected the world today? • Louis Pastuer has definitely impacted the world today, because without his discoveries there might not be a cure or a treatment for rabies, or at least back in the 1800s thousands people would’ve died because of that disease. Pastuer also came up with the idea of vaccinations, and really helped us today since people take vaccinations probably every year to stop bacteria and germs to affect their body.
