Louis Pastuer
 
Lois Pastuer is probably best known for his invention of pastuerization, but he also disproved the theory of spontanious generation by placing broth into two S-neck flasks. He left the one on its side, being exposed to the air. He left the other one up right and not in contact w/ the air. When the first one was cloudy with contamination, but the other one was not, he proved the theory of biogenisus. Any other interesting facts about him?

Louis Pasteur
 
Louis Pasteur was born in Dole, Jura département, France, the son of a tanner. His parents were Jean Joseph and Jeanne Pasteur and his sisters were Virginie, Josephine, and Emilie Pasteur. His sister Emilie had a sickness that froze her mind and even though she grew to adult size she still had the mind of a five-year old. Louis pasteur went to school at the École Normale Supérieure in Paris in 1843 and got a doctoral degree in 1846. He studied chemistry, but showed little promise at first (one of his professors described him as "mediocre").

RE: What did he discover
 
He discovered Pasteurization, the process of heating something to kill all bacteria. He also helped discovering that all living things come from living things, also known as biogenisis.

cool but what was the thing he invented to kill the bacteria.

BroadwayBaby 11-17-2005 12:34 PM

He didn't invent anything, he just simply found that if you heat something over a certain degree, it would kill all the bacteria!

Pastuer
 
Actually to kill the bacteria, he said that heat the substance to a certain temperature and then cool it suddenly. Milk bacteria is still killed that way.

Hmmm
 
I believe that Louis Pasteur had a good mind, and was pretty smart.He also studied crystals and became a professer when he was 31. He studied crystals using a beam of light. I just heard a "very nicely done speech:eek:" about him at about 8:00 this morninhg, and that is all I rmember

More facts on Louis Pasteur
 
Pasteur's method of immunization was effective and was employed by many other physicians, eventually leading to the eradication of the diseases typhus and polio as threats. Pasteurization led to the elimination of contaminated milk and other drinks as sources of disease. In fact, Pasteur inaugurated the modern age of medicine, leading to an increase in the human life span in much of the (wealthy) world and a surprising population explosion.

That's why he's been called the "Father of Medicine"!

He studied cyrstals at the age of twenty six, using only a beam of light and a small magnifying glass!
