Louis Pasteur (1822-1895) was a French chemist and physicist known as the "father of microbiology." Thanks to his advances in microbiology, antibiotics, sterilization and clinical hygiene would emerge.
In 1857 Pasteur shows that infections are related to microorganisms, which can be cultivated and therefore studied.
In 1880, he found that it was possible to protect oneself from infectious diseases by injecting attenuated germs. We are facing the development of the first vaccine against rabies. He is also responsible for the technique known as pasteurization.
