9.Louis Pasteur was born in Dole,France on December 27,1822.His family was poor,and during his early education Pasteur was an ordinary student who enjoyed art and singing.However,when Pasteur was exposed to science as a teenager,he knew he had found his career.In 1838,Pasteur went to college to become a science teacher.He then became a chemistry professor at the University of Strasbourg.He got married in 1849and had five children.However,three died young from typhoid fever (伤寒症).It was the deaths of his children that drove Pasteur to investigate the infectious disease in order to find a cure.
During Pasteur's time,people believed that bacteria(细菌) appeared due to"spontaneous generation(自然发生)".They thought that the bacteria just appeared out of nowhere.Pasteur carried out experiments to see if this was true.Through his experiments he proved that germs 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 title of Father of Germ Theory.
As Pasteur learned more about bacteria,he began to think they may be the cause of diseases in humans.When the French silk market was threatened by a disease to silkworms (蝉),Pasteur decided to investigate.He discovered that this disease was caused by germs.By killing them from the silkworm farms,he was able to cease the disease and save the French silk business.
