What is Microbiology?
Anton Van Leeuwenhoek
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
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.
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.
