Quizplus · Accepted Answer

Louis Pasteur is credited with establishing the germ theory of disease, which states that microorganisms are the cause of infectious diseases. He conducted experiments that proved the link between microbes and disease, including the famous experiment with swan-necked flasks that showed that sterilized broth could remain free of microbial growth as long as the flask remained sealed. This theory had a profound impact on medicine and public health, leading to the development of improved sanitation practices, vaccines, and antibiotics.
