Who was the first person to determine that germs caused disease? Select one of the options below as your answer:
a. Robert Koch
b. Marie Curie
c. Albert Einstein
d. Louis Pasteur
The correct answer is d. Louis Pasteur
and the name for his finding is the Gem Theory of disease - the theory that disease is caused by Gems - until then people didn't know this. He did this by working on a plague of silkworms.
He also proved that fermentation is caused by microorganisms.
It would be "d. Louis Pasteur"--a French chemist--who was the first person to determine that germs caused disease, since this was a major breakthrough in both medicine and science in general.
