Question

Louis Pasteur
Louis Pasteur was born in Dole, France on December 27, 1822. His family was poor and during his early education he
was an average student who enjoyed art and singing. However, when Louis was exposed to science as a teenager, he
knew he had found his calling. n 1838, Louis went to college to become a science teacher. He earned degrees in
mathematics, physics, and chemistry. He then became a chemistry professor at the University of Strasbourg.While at the
University he fell in love with the daughter of the university's rector, Marie Laurent. He and Marie married in 1849. They
had five children, however, three died young from typhoid fever. It was the deaths of his children that drove Louis to
investigate infectious diseases in order to find a cure.
Scientific Discoveries
Bacteria and Germ Theory
During Pasteur's time, people believed that microbes such as bacteria appeared due to "spontaneous generation." They
thought that the bacteria just appeared out of nowhere. Pasteur ran experiments to see if this was true. Through his
experiments he proved that germs (i.e. bacteria) were living things that came from other living things. They didn't just
spontaneously appear. This was a major discovery in the study of biology and earned Pasteur the nickname the "Father of
Germ Theory."
Pasteurization
Pasteur used his knowledge of germs to investigate how beverages such as wine and milk were spoiled by microbes such
as bacteria and molds. He found that heating up the liquids would kill most of the microbes and allow the beverages to
last longer and be safer to drink. This process became known as pasteurization and is still done on many foods such as
milk, vinegar, wines, cheese, and juices.
Silk Worms
As Pasteur learned more and more about bacteria, he began to think they may be the cause of disease in humans. When
the French silk market was threatened by a disease to silkworms, Pasteur decided to investigate. He discovered that this
disease was caused by microbes. By eliminating the microbes from the silkworm farms, he was able to end the disease
and save the French silk business.
Vaccinations
Pasteur continued to investigate with diseases. He found that he could make a weak form of a disease that would cause
people to become immune to the stronger form of the disease. He called this weak form a "vaccine." He first discovered
this by working with cattle on the disease anthrax. The first vaccine he gave to a human was the rabies vaccine. He
administered it to a nine year old boy name Joseph Meister in 1885.
Legacy
Today Louis Pasteur is known as one of the most important scientists in history. His discoveries led to an understanding
of microbes and diseases that has helped to save millions and millions of lives.
Pasteur is most remembered by the Pasteur Institute which he established in 1887. Today the Pasteur Institute is one of
the world leaders in battling infectious diseases.
Louis Pasteur died in 1895 from a stroke. He was buried in the Cathedral of Notre Dame in Paris, France.
