Louis Pasteur
Louis Pasteur was born on December 27, 1822 in Dole, France. Growing up, he was not very interested in his studies and enjoyed drawing and fishing. From 1847 to 1862 he was a physicist and a chemist, from 1862 to 1877 he was a biologist, and from 1877 to 1887 he worked as a microbiologist. During his years, he came up with cures for diseases such as rabies, anthrax, and silkworm disease.
Pasteur is famous for studying alcohol fermentation and he discovered that under polarized light, an inactive substance became active due to fermentation. He stated these four principles of fermentation:
Pasteur's research was helpful, but it didn't support the spontaneous generation theory. Meaning, it didn't give reason to why living organisms develop out of non-living matter. He later explained in a paper that airborne dust carries things like yeast and microorganism during the fermentation process. He concluded that even the most perishable things could be preserved if they could be kept away from the germs. His idea of Pasteurization came about when it was discovered that all fermentable liquids could be prevented from spoiling through a heating treatment. He came up with the process mainly to preserve beer and wine, but was also used on other drinks and foods.
His work with the Germ Theory was some of his most important work. In his microbiology career, he was able to prove that foreign microorganism were the cause of many diseases. He was then able to come up with many vaccines for such diseases. Louis Pasteur also had three of his children die of typhoid fever, so finding a way to protect others was important to him. He founded an international fund, which today has turned into the Pasteur Institute in Paris, France. People at this institute research various diseases and find cures and ways of prevention. Over 2,000 people from each and every continent have banded together to make groundbreaking discoveries in the field of microbiology. Some notable accomplishments would be their discovery of HIV and the bacterium that caused the plague. They really carry on Pasteur's mission: to prevent illness and disease.

- All fermentation is caused by a microorganism.
- There's a particular ferment for every given fermentation.
- a sterile culture medium is required for ferment growth.
- The medium has to be seeded with absolute ferment particles.
