Study Notes
Ancient Civilizations (3000 BCE - 500 CE)
- Early observations of microorganisms:
- Ancient Egyptians (3000 BCE): observed fermentation and spoilage
- Ancient Greeks (500 BCE): Aristotle and Hippocrates described "bad air" and "miasma" as causes of disease
- Ancient Romans (100 BCE): observed fermentation and proposed "contagion" as a cause of disease
Microscope Development (1590 - 1676)
- Key figures:
- Zacharias Janssen (1590): invented the first compound microscope
- Antonie van Leeuwenhoek (1676): discovered bacteria, yeast, and protists using a hand-held microscope
Germ Theory (1676 - 1881)
- Key figures:
- Antonie van Leeuwenhoek (1676): observed microorganisms in water and proposed they caused disease
- Louis Pasteur (1857): developed the germ theory of disease and introduced vaccination
- Robert Koch (1881): developed Koch's postulates to identify microorganisms as causes of disease
Golden Age of Microbiology (1881 - 1914)
- Key discoveries:
- Isolation of bacteria: Robert Koch (1881) and Louis Pasteur (1881)
- Discovery of viruses: Dimitri Ivanovsky (1892) and Martinus Beijerinck (1898)
- Development of serology: Emil von Behring (1890) and Shibasaburo Kitasato (1890)
Modern Era (1914 - present)
- Key developments:
- Antibiotics: Alexander Fleming (1928) and Ernst Boris Chain (1941)
- Molecular biology: James Watson and Francis Crick (1953)
- Recombinant DNA technology: Stanley Cohen and Herbert Boyer (1973)
- Genomics and proteomics: late 20th century
Other Key Figures and Contributions
- Microbial ecology: Sergei Winogradsky (1850s) and Martinus Beijerinck (1900s)
- Virology: Wendell Stanley (1930s) and Frank Macfarlane Burnet (1940s)
- Immunology: Elie Metchnikoff (1890s) and Karl Landsteiner (1900s)
