Louis Pasteur is most known for his accomplishments in science, including the process of pasteurization. Pasteur also developed several vaccinations, including ones for anthrax and one for rabies.
Another major accomplishment for Pasteur was saving the silk industry. He discovered that microbes were infecting silkworms, which led to a decreased production of healthy eggs. His method of preserving the silkworms is still used in countries that produce silk, as of 2014.
Pasteur also saved the wine and beer industries in France from financial ruin when problems with contamination occurred. His method of pasteurization helped to kill organisms that impacted the quality of the wine and beer.
