Robert Koch
1843–1910 · Germany · Founder of medical bacteriology.
Contribution
- Identified causative agents of anthrax, tuberculosis, and cholera.
- Developed rigorous culture methods and staining approaches.
- Formulated Koch’s Postulates — criteria linking a microbe to a disease.
- Solidified Germ Theory with specific etiologic proofs.
Why It Still Matters
Koch’s logic still structures how we think about etiology, culture, and pathogen discovery — even when molecular methods replace pure culture.
