Pasteur is also regarded as one of the fathers of the germ theory of diseases, which was a minor medical concept at the time. [11] His many experiments showed that diseases could be prevented by killing or stopping germs, thereby directly supporting the germ theory and its application in clinical medicine.
Pasteur's portrait by Edelfelt is the best-known portrait of the French chemist Louis Pasteur.Painted by Albert Edelfelt (1854–1905) in 1885 the painting shows Pasteur in his laboratory at the rue d'Ulm, surrounded by his experimental apparatus, the innovative laboratory glassware used in the experimental methods, developed by him on the field of bacteriology in the late 19th century.

Louis Pasteur was a French chemist who discovered chirality while studying crystals. This discovery became the basis for a new form of chemistry called stereochemistry . [ 49 ] [ 50 ] While Pasteur was studying paratartrate crystals in 1857, he discovered that his calcium paratartaric acid solutions were growing fungi.

A representation by Robert Seymour of the cholera epidemic depicts the spread of the disease in the form of poisonous air.. The miasma theory was the predominant theory of disease transmission before the germ theory took hold towards the end of the 19th century; it is no longer accepted as a correct explanation for disease by the scientific community.
The first human virus to be identified was the yellow fever virus. [6] In 1881, Carlos Finlay (1833–1915), a Cuban physician, first conducted and published research that indicated that mosquitoes were carrying the cause of yellow fever, [ 7 ] a theory proved in 1900 by commission headed by Walter Reed (1851–1902).
English: Louis Pasteur’s pasteurization experiment illustrates the fact that the spoilage of liquid was caused by particles in the air rather than the liquid itself. These experiments were important pieces of evidence supporting the idea of Germ Theory of Disease.
One of the chemical processes that Pasteur studied was the fermentation of sugar into lactic acid, as occurs in the souring of milk. In an 1857 experiment, Pasteur was able to isolate microorganisms present in lactic acid ferment after the chemical process had taken place. [9] Pasteur then cultivated the microorganisms in a culture with his ...
