Two remarkable discoveries

• Pasteur found that heating beverages to a temperature between 140F to 212F (60°C-100°C) killed bacteria in those liquids - a process known as pasteurization.
• He also turned his attention to the development of vaccines. He used artificially weakened viruses as vaccines and went on to develop a vaccine for anthrax and rabies.

Pasteur provided the proof for the existence of the germ theory of disease and revolutionized the way we think about human health.
