Q:

What did Louis Pasteur discover?

A:

Louis Pasteur was a scientist who discovered the process of preparing food known as pasteurization. He also developed the vaccinations for rabies and anthrax during his study on germs.

Pasteur was a French microbiologist and chemist who was born in December of 1822 in Dole, which is located in the Jura region of France. In school, Pasteur was described as nothing more than an average student who was very skilled at painting and drawing. During the Napolenic Wars, he served as a sergeant major. After the wars, he earned two bachelor's degrees and a doctorate at the École Normale in Paris.

Pasteur was appointed the dean of the science faculty at the University of Lille in 1845. There he started his work on finding a solution to the problems associated with the manufacture of alcoholic beverages. While studying germs, he found that it was bacteria that led to the souring of not only wine and beer but also milk. Pasteur then discovered that boiling and cooling a liquid removes the bacteria. This process was later named pasteurization. His first successful test of pasteurization was completed on April 20, 1862.

In 1868, Pasteur became partially paralyzed because of a brain stroke. Despite this, he continued to work on his research. His paralysis got progressively worse until his death in September of 1895.
