• Discovered that pasteurization was something that could stop food spoilage
• Pasteurization: the application of a high heat for a short time to kill harmful bacteria in
beverages
How was he lucky in his discovery of pasteurization?—there we're no endospores and that
would should have been detected during the search for spontaneous generation but it didn't
Robert Koch - Proved that bacterium causes anthrax and provided the experimental steps of
