Louis Pasteur (Dec. 27, 1822-Sept. 28, 1895) was a French chemist and microbiologist. He is most famous for inventing the process that keeps milk from going sour, which is now known, in his honor, as pasteurization. He also performed experiments that confirmed the germ theory of disease, created the first rabies, anthrax and chicken cholera vaccines, was a founder of bacteriology and made numerous discoveries in chemistry. He was also the Dean of the faculty of sciences at Lille University.
Pasteur was a devout Christian, and did not see any conflict between science and Christianity, remarking that "a bit of science distances one from God, but much science nears one to Him." Pasteur experienced many hardships throughout his life, including the death of three of his five children to childhood diseases including polio, but these hardships only served to strengthen his faith and his determination to find cures. Through it all Pasteur gave God the glory, stating that "the more I study nature, the more I stand amazed at the work of the Creator."
