Untitled Worksheet
Source Analysis: Louis Pasteur and Germ Theory
Source A: Louis Pasteur's Discovery of Germs
"In 1865, I observed microscopic organisms in spoiled wine, which led me to conclude that these tiny life forms were responsible for fermentation and decay. My experiments showed that heating wine to a certain temperature prevented spoilage, a process I called pasteurization. This discovery suggested that microorganisms could cause disease, opening the way for new methods of preventing illness. I believed that by understanding microbes, we could develop better sanitation methods and vaccines to fight infections." Provenance: Louis Pasteur, 1865, scientific report
