Louis Pasteur was a French chemist and microbiologist who developed antidotes and cures to many dangerous illnesses such as anthrax and rabies. He also successfully invented a way to pasteurize milk and make it safe from deadly diseases. Pasteur also proved how germs grew from contamination and disproved the theory of spontaneous contamination.
Pasteur was born in Dole, Eastern France. While he was considered a hard-working student, he was not considered exceptionally brilliant. He was even called mediocre by one of his professors. After obtaining posts at Strasbourg, Lille, and Paris, he spent a lot of time researching chemistry.
His most important discoveries were in the field of germ study. He learned that germs required certain microorganisms to develop. Using this knowledge, he found that the fermentation of yeast could be delayed. Louis Pasteur then turned to practical ways of killing bacteria in liquids such as milk. His process of pasteurization successfully killed bacteria in milk without destroying milk protein. This was a radical discovery and made drinking milk safe.
