Louis Pasteur (1822-1895). He was the French scientist who developed the process of “pasteurization” for milk. He developed the vaccine for anthrax and chicken cholera in 1881 and the rabies vaccine in 1885. Pasteur was a chemist and physicist who revolutionized the medical field by establishing the germ theory of disease, organic basis and regulation of fermentation, and bacteriology. Pasteur’s research laid the foundation for the control of Tuberclosis, cholera, diphtheria, tetanus, and several other diseases. He was appointed dean of the faculty of sciences at Lille University in 1854. In 1888, the Pasteur Institute was founded to treat rabies and advanced biological research.

Pasteur made the following comments when describing anaerobic bacteria:

“The more I study nature, the more I stand amazed at the work of the Creator. Into his tiniest creatures, God has placed extraordinary properties that turn them into agents of destruction of dead matter.”

He was questioned in his mature years about his faith and replied:

“The more I know, the more does my faith approach that of a Breton peasant. Could I but know all, I would have the faith of a Breton peasant woman.”


He was one of the first European scientists who rejected the theory of spontaneous generation and evolution, Pasteur insisted that life only arises from life.

“Microscopic beings must come into the world from parents similar to themselves…There is something in the depths of our souls which tell us that the world may be more than a mere combination of events.”

Louis Pasteur once declared in his lectures,

“Science brings man nearer to God.”
