Louis Pasteur is known for proposing germ theory. In what year was this theory proposed?

• A. 1849
• B. 1900
• C. 1862
• D. Proposed germ theory

Answer: (C)

Germ theory is the idea that microorganisms are the cause of many diseases and of fermentation processes. Louis Pasteur helped establish this by showing microbes drive fermentation and can be linked to disease, challenging the older ideas that disease came from “miasma” or spontaneous generation. He publicly proposed the germ theory in 1862, a pivotal moment that shifted medicine toward identifying specific germs responsible for illnesses. So, 1862 is the year associated with the proposal of this theory. The other options aren’t the year Pasteur first proposed it, or aren’t years at all.
