History of Microbiology

Microbiology began in 1665 when Robert Hooke observed cells in cork using a crude microscope.

In the 1670s, Antonie van Leeuwenhoek crafted high-quality lenses to observe microorganisms in water.

He created the first visual records of bacteria and protozoa, earning him the title “Father of Microbiology.”

In 1861, Louis Pasteur’s swan-neck flask experiments proved that microbes could originate from the air, refuting the idea of spontaneous generation.

The First Golden Age of Microbiology, from 1857 to 1914, brought transformative advancements.

This era marked the development of pasteurization to eliminate harmful microorganisms, the formulation of Koch's postulates linking specific microbes to diseases, and the creation of vaccines using attenuated pathogens—pioneering modern immunology.

In 1928, Alexander Fleming’s discovery of penicillin began the antibiotic era, leading to the Second Golden Age.

The Third Golden Age, starting in the 1990s, focused on genomics and biotechnology, leading to genome sequencing, microbiome research, and microbial engineering.
