Microbiology History

History of Microbiology

Louis Pasteur Louis Pasteur is also known as the father of microbiology. He has many contributions to microbiology: He has proposed the principles of fermentation for the preservation of food. He introduced sterilization techniques and developed steam sterilizers, hot air oven, and autoclave. He described the method of pasteurization of milk. He had also contributed for designing the vaccines against several diseases such as anthrax, fowl cholera, and rabies He disproved the theory of spontaneous generation of disease and postulated … Read more

The Germ Theory of Disease

Germ Theory of Disease

Before the Germ theory of disease, the causes suggested for the occurrence of disease were the effect of supernatural phenomena like planetary alignments, effect of bad bodily humors and the faulty environment. For example, in ancient Greece, it was thought that disease was spread not via direct contact with other infected individuals, but rather via infectious “seeds” in the air or food products. The predominant theory until germ theory of disease was eventually accepted in the 19th century was termed … Read more

Spontaneous Generation

Spontaneous generation is an obsolete theory which states that living organisms can originate from inanimate objects. The theory believed that dust created fleas, maggots arose from rotting meat, and bread or wheat left in a dark corner produced mice among others. Although the idea that living things originate from the non-living may seem ridiculous today, the theory of spontaneous generation was hotly debated for hundreds of years. During this time, many experiments were conducted to both prove and disprove the … Read more

History of Microbiology

Physics began in ancient times, mathematics even earlier, but the knowledge of tiny living things, their biology, and their impact on human lives have only been around since the late 19th century. Until about the 1880s, people still believed that life could form out of thin air and that sickness was caused by sins or bad odors. Opinions about why diseases afflicted people differed between cultures and parts of society and the treatments differed as well. Diseases were thought to … Read more

Microbiology developed as a scientific discipline from the era of Louis Pasteur (1822- 1895) himself. He first coined the term “microbiology” for the study of organisms of microscopic size. For his innumerable contributions in the field, he is also known as the Father of Microbiology. He is renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is remembered for his remarkable breakthroughs in the causes and … Read more
