who is louis pasteur?

Question

wad is he

Answer 1

Invented Pasteurization for milk...

Louis Pasteur (December 27, 1822 – September 28, 1895) was a French microbiologist and chemist. He is best known for demonstrating how to prevent milk and wine from going sour, which came to be called pasteurization. His experiments confirmed the germ theory of disease, and he created the first vaccine for rabies. He became one of the main founders of bacteriology, the other major figure being Robert Koch. He also made many discoveries in the field of chemistry, most notably the asymmetry of crystals.

Answer 2

Louis pasteur was a scientist who proved that spontaneous generation is wrong and does not exist. Spontanteous generation is the theory that states that any living thing can come from something non-living. The opposite of Spontanteous generation is Biogenesists. There were many many more experiments trying to prove one or the other before Louis Pasteur but none of them ever really found out that Spontaneuus Generation does not exist. Louis Pasteur figured this out. I think he lived in the 1800s...1822-1895. Hope I helped! Good luck!

Answer 3

Louis Pasteur
Scientist
Louis Pasteur is the 19th-century biologist and chemist whose work with germs and microorganisms opened up whole new fields of scientific inquiry, aided industries ranging from wine to silk, and made him one of the world's most celebrated scientists. Pasteur became a professor of chemistry at the University of Lille in 1854 , and soon began studying fermentation in wine and beer. He became convinced that, as he put it in an 1878 paper, "the germs of microscopic organisms abound in the surface of all objects, in the air and in water." He determined that such microorganisms could be killed by heating liquid to 55 degrees Celsius (about 130 degrees Fahrenheit) or higher for short periods of time. This simple process became known as pasteurization, a process used today in milk and many other beverages. Pasteur then turned his attention to other aspects of microorganisms. He virtually created the science of immunology, showing that certain diseases (like rabies) could be prevented by what he called vaccination: injecting animals with weakened forms of the disease. So great were Pasteur's successes that an international fund was raised to create the Louis Pasteur Institute in 1888. Pasteur worked with the institute until his death, and it continues today as a center of microbiology and immunology.

Answer 4

Pasteur, Louis (1822-1895), world-renowned French chemist and biologist, who founded the science of microbiology, proved the germ theory of disease, invented the process of pasteurization, and developed vaccines for several diseases, including rabies.

Pasteur was born in Dôle on December 27, 1822, the son of a tanner, and grew up in the small town of Arbois. In 1847 he earned a doctorate at the École Normale in Paris, with a focus on both physics and chemistry. Becoming an assistant to one of his teachers, he began research that led to a significant discovery. He found that a beam of polarized light (see Optics) was rotated to either the right or the left as it passed through a pure solution of naturally produced organic nutrients, whereas when polarized light was passed through a solution of artificially synthesized organic nutrients, no rotation took place. If, however, bacteria or other microorganisms were placed in the latter solution, after a while it would also rotate light to the right or left.

Pasteur concluded that organic molecules can exist in one of two forms, called isomers (that is, having the same structure and differing only in mirror images of each other), which he referred to as “left-handed” and “right-handed” forms. When chemists synthesize an organic compound, both of these forms are produced in equal proportions, canceling each other’s optical effects. Living systems, however, which have a high degree of chemical specificity, can discriminate between the two forms, metabolizing one and leaving the other untouched and free to rotate light.
