Louis Pasteur was born in Dole, France on December 27th in 1822. He was the son of Jean Pasteur and Jeanne-Etiennette Roqui. His father was a poorly educated tanner, who had high hopes for his son to excel in his education. *

Pasteur gave a significant impact to the world of scientific research through his numerous contributions. Earlier in his life, Pasteur worked as a chemist, and dealt with the specific nature of tartaric acid. Tartaric acid is a type of acid that occurs naturally in many plants, and thus ended up being a key component to the discovery of chirality. Jean Baptiste Biot first observed the tartaric acid’s ability to have its polarized light rotated in 1832. Pasteur later (1847) continued this research. He investigated the shapes of crystals of the ammonium sodium tartrate, discovering them

Once this was of knowledge, Pasteur invented a process, which is now known to be pasteurization. Pasteurization would process liquids, and heat them in order to kill the majority of bacteria, and any molds if present. He performed the process for the first time on April 20th in 1862 with Claude Bernard.

Once seeing contamination of beverages, Pasteur began to question if the microorganisms that cause disease also affect humans and animals. He began thinking of ways to prevent microorganisms from entering the body of humans. This subsequently led to British surgeon, Joseph Lister, developing surgical antiseptic methods.

In Ales (a commune in France) in 1865, there were two parasitic diseases that were killing a large number of silkworms. Pasteur took part in research for years that demonstrated that these diseases were caused by a microbe, a microbe that was specific in attacking silk worm eggs. He demonstrated that if the microbe in silkworm nurseries were eliminated, it would then eradicate the
