📊 Why Was Germ Theory Revolutionary?

Before: 2,000 years of miasma theory. Doctors tried to prevent "bad air." No understanding of infection.
After: Doctors could target SPECIFIC germs. Led to: antiseptics (Lister), vaccines (Pasteur's rabies, etc.), antibiotics (penicillin), public health (clean water).
Technology: Better microscopes (19th century) made it possible to see microorganisms clearly.
Rivalry: Franco-Prussian War (1870-71) → France and Germany competed in science. Pasteur (French) vs Koch (German) rivalry accelerated discoveries.
