The study of microscopic organisms. Microbiologists are some of the people who study bacteria and diseases. They as well as study how our cells interact with many things such as drugs and poisonous materials. They also help us design things like microchips for computers. Microbiology is interesting.

Anton Van Leewenhoek

Leewenhoek was never thought to ever have potential in any other way. It was his curiosity that led him to his success. He was the first scientist to discover microscopic organisms. He started with the discovery of bacteria, then he moved to things such as microscopic protists, sperm cells, blood cells and many more things. Without him we wouldn't have invented the microscope and found microscopic organisms as soon as we had. He contributed a huge part in science not only in the branch of microbiology but other branches that use his technology.

Robert Koch

Koch was a very intelligent person from the start. At the age of five he taught himself how to read by just studying the newspapers his parents were done with. in 1862 he went into college to study medicine. He was influenced by an article that brought the idea of disease being caused by small living organisms. He was set out on proving that bacillus was the cause of disease. He proved it by taking the spleens of animals with bacilli that had died of anthrax, and tested it on the mice. He also tested healthy animals spleens on the mice. He found that bacilli can be transmitted by blood. He also found that they reproduce when they are in favorable conditions. His contributions to science were that he helped study diseases and how they were spread as well as create a system for diseases which was called Koch's postulate, which was a way of determining the disease.

Louis Pasteur

From the beginning he was an average person. In 1854 he was appointed the professor of chemistry and the dean of science. He created a process called pasteurization, which is the process of boiling and then cooling a liquid to kill any and all bacteria in it. After accidentally exposing chickens to the attenuated form of a culture he came to the discovery that they became immune to the actual virus. He used this to create cures for anthrax, cholera, TB and smallpox. He contributed ways of finding cures to diseases as well as cures for some of the worst diseases of his time.
