What is Microbiology?

Microbiology is the study of micro-organisms. For example bacteria, various diseases, and fungi. Microbiology helps scientists understand how the cell works. This branch discovers new life through a microscope.


Anton Van Leeuwenhoek

Born on October 24th, 1632 in Delft Holland, Anton Van Leeuwenhoek discovered bacteria and many other things that opened up a new life for Biology. His family was tradesmen with little money so he had no education or could even attended university. He died on August 30th, 1723.

Leeuwenhoek created many microscopes and used them to look at plant and animal tissue, crystals, and fossils. With this invention, he was the first man to discover blood cells and see the living sperm cells of plants and animals. He had a skill at grinding lenses but he had a illustrator to draw what he written about the organisms under his microscope.

Anton Van Leeuwenhoek had helped us see micro-organisms and discover other parts of science that nobody seen before at that time. http://www.ucmp.berkeley.edu/history/leeuwenhoek.html

Robert Koch

Robert Koch was born December 11, 1843 and died May 27, 1910. Growing up,in Germany, he had an interest in biology and eventually he studied medicine at university. He became a doctor and after that he began studying algae discovering bacteria.

Koch investigated a disease called anthrax, it affected farmers and farm animals. He found out it was spores that lived for awhile after that animal had died then could then affect other animals. He began discovering other germs directed towards humans and created a method to discover a way to find out which germ caused an infection.

Many scientists are inspired by Robert Koch and the things he did for organisms, diseases, and his experiments.

Louis Pasteur

Louis Pasteur was born in Dole, France in December 27, 1822. He did many things for microbiology, such as creating vaccines for diseases and made pasteurization. He got many degrees throughout his life in college. He got married to a woman named Marie Laurent and had five children but only two survived. Pasteur died September 28, 1895.

Pasteur studied various kinds of fermentation. He discovered the germ theory of fermentation stating that a specific organism is connected to each fermentation. This helped him create the Pasteur effect. He noticed the germ theory of fermentation did not follow others belief with spontaneous generation. He did an experiment and later proved that spontaneous generation could not be true and living things can not come from nonliving things.

Louis Pasteur did many things for microbiology. He proved spontaneous generation wrong and helped us see new things about organisms.
