Let’s zoom in on this microscopic world!

History of Microbiology

The story of microbiology is a tale of revolutionary discoveries:

Early Observations (Pre-1674)

• Ancient civilizations: Used fermentation for bread, beer without understanding microbes
• Roman scholar Marcus Terentius Varro (1st century BCE): Suggested “tiny animals” cause disease

The Birth of Microbiology (1674-1850)

• Antonie van Leeuwenhoek (1674): First to observe microbes using homemade microscopes (“animalcules”)
• Edward Jenner (1796): Developed first vaccine (smallpox) without knowing about viruses

The Golden Age (1850-1940)

• Louis Pasteur (1850s): Disproved spontaneous generation, developed pasteurization
• Robert Koch (1876): Established Koch’s postulates linking microbes to disease
• Alexander Fleming (1928): Discovered penicillin, launching antibiotics era

Modern Microbiology (1940-Present)

• DNA discovery (1953): Revolutionized understanding of microbial genetics
• HIV identification (1983): Demonstrated viral disease mechanisms
• CRISPR (2012): Gene-editing technology from bacterial immune systems
• COVID-19 pandemic (2020): Showcased microbiology’s critical role in public health

Today, microbiologists use electron microscopes, DNA sequencing, and AI to study microbes.
