Louis Pasteur Quiz – Founder of Microbiology

Louis Pasteur was a French chemist who showed that microorganisms cause fermentation and disease. His swan-neck flask experiments disproved the idea that life arises spontaneously from nonliving matter.

He developed pasteurization to stop spoilage, saved France's silk industry and created vaccines for chicken cholera, anthrax and rabies. His 1885 rabies treatment of Joseph Meister made him a hero.

Pasteur's germ theory, along with Robert Koch's work, transformed medicine and hygiene. The Pasteur Institute he founded remains a world leader in research on infectious diseases.
