The hero of medicine

 "Louis Pasteur was not a doctor or a surgeon, but no one has done as much for medicine and surgery as he did" - Henri Mondor.

Louis Pasteur, was a French chemist and bacteriologist, founder of microbiology and a pioneer of modern medicine. Since 1856, when he began to study fermentation applied to the preservation of wine and milk, he had the theory that contamination by microorganisms was the factor responsible for these drinks deteriorating rapidly when they were opened. He therefore resolved that by heating them once packaged to a temperature that would kill these microorganisms, not only would their rapid deterioration be prevented, but the diseases caused by them would also be prevented. Pasteur was definitely a chemist who fundamentally changed our understanding of biology.

By proving that diseases were spread by the transmission of pathogens, the sterilization of medical equipment and the cleaning of professionals after treating a sick patient became of crucial importance. The other great achievement Louis Pasteur is remembered for was the development of vaccines. The procedure, however, consisted in exposing a person to a similar but weaker disease and was therefore limited to those human diseases of which a "relative" was known in other animals. Instead, Pasteur revolutionized the method by creating a vaccine from the human disease-causing pathogen itself.

"Pasteur developed the germ theory of infectious diseases, according to which infections are due to the ability of microorganisms to transmit from one person to another through the air or physical contact."
