Next time you pour milk over your cereal of choice, you might want to raise your spoon in salute to Louis Pasteur, whose process of pasteurization made it so we could consume it without risk of death! This alone has saved thousands upon thousands of lives, but Pasteur's heroism doesn't end there; he created the first vaccines for rabies and anthrax, which led to a far greater understanding of the germ theory of disease. He is often regarded as one of the fathers of microbiology, together with Ferdinand Cohn and Robert Koch.
