Louis Pasteur (1822–1895) is revered by his successors in the life sciences as well as by the general public. In fact, his name provided the basis for a household word—pasteurized.

Louis Pasteur, who lived from 1822 to 1895, is arguably the world's best-known microbiologist. He is widely credited for the germ theory of disease and for inventing the process of pasteurization – which is named after him – to preserve foods. Louis Pasteur (born December 27, 1822, Dole, France—died September 28, 1895, Saint-Cloud) was a French chemist and microbiologist who was one of the most important founders of medical microbiology. Pasteur’s contributions to science, technology, and medicine are nearly without precedent. He pioneered the study of molecular asymmetry; discovered that microorganisms cause fermentation and disease; originated the process of pasteurization; saved the beer, wine, and silk industries in France; and developed vaccines against anthrax and rabies.
