Emile Roux

Emile Roux was a pioneering French bacteriologist and physician in the late 19th and early 20th centuries. He made significant contributions to understanding infectious diseases, particularly diphtheria, and worked closely with Louis Pasteur on developing vaccines. Roux helped establish germ theory—a scientific view that microorganisms cause many diseases—and developed methods to weaken bacteria to create effective vaccines. His work was fundamental in advancing immunology and public health, ultimately saving countless lives through improved disease prevention strategies.
