This treatment proved to work and saved countless lives and because of his study in germs, Pasteur encouraged many doctors to sanitize their hands and equipment before surgery.

Good thing it worked: Pasteur was not a licensed physician and could have been prosecuted had the vaccine failed. The legalities were forgotten and Pasteur instead became a national hero.

on July 6, 1885, Pasteur agreed with some reluctance to treat his first human patient, Joseph Meister, a nine-year-old who was otherwise doomed to a near-certain death. Success in this case and thousands of others convinced a grateful public throughout the world to make contributions to the Institut Pasteur. It was officially opened in 1888

In 1885, Pasteur was lauded for one of his most famous developments—a vaccine against rabies (or 'hydrophobia'). He had successfully vaccinated dogs against the disease; soon after the vaccine was tested successfully on humans.

Eventually, after many experiments Pasteur succeeded in producing a weakened and harmless culture of anthrax bacteria. He inoculated cattle and sheep with this giving them a mild form from which they recovered. When these animals were put with others who had a severe form they remained unaffected. They were immune.

When he was asked if he believed in evolution, he said, "no." His studies showed that life only comes from life and that life comes from parents similar to themselves. Pasteur questioned the theory of evolution, because Darwin did not base his ideas on experimental proof. Louis said, "Do not put forward anything that you cannot prove by experimentation."

He also described the process of fermentation for the first time, invented the process of pasteurization, and developed important scientific theories such as the germ theory of disease.

Pasteur's first vaccine discovery was in 1879, with a disease called chicken cholera. After accidentally exposing chickens to the attenuated form of a culture, he demonstrated that they became resistant to the actual virus. Pasteur went on to extend his germ theory to develop causes and vaccinations for diseases such as anthrax, cholera, TB and smallpox.

In the modest laboratory that he was permitted to establish there, he continued his study of fermentation and fought long, hard battles against the theory of spontaneous generation.

He eventually created the process of pasteurization, boiling and then quickly cooling liquids that could spoil, like spirits and milk. This alone has prevented countless incidences of disease.

in 1854, Pasteur was appointed professor of chemistry at the University of Lille. Part of the remit of the faculty of sciences was to find solutions to the practical problems of local industries, particularly the manufacture of alcoholic drinks. He was able to demonstrate that organisms such as bacteria were responsible for souring wine and beer (he later extended his studies to prove that milk was the same), and that the bacteria could be removed by boiling and then cooling the liquid. This process is now called pasteurisation.

As Pasteur was growing up, his teachers thought that Louis was not fit for advanced studies, and felt he should carry on the work of his father as a tanner of leather. However, one teacher realized that Pasteur was bright and found he was slow, yet methodical and persistent.

Eventually Pasteur was schooled in Paris by some of the best teachers.
