In the summer of 1885，nine-year-old Joseph Meister was very ill He had been wounded by a sick dog that had rabies（狂犬?。琣 very dangerous disease．His parents were told that there was probably only one man who could save Joseph's life--Louis Pasteur．
   When Pasteur was a young boy in France，he spent many hours every day with the chemist （藥劑師） who lived in his small town．At that time，the chemist had to make all the medicines himself．Young Louis enjoyed watching the chemist as he worked and helped those people who came to him each day．
   As a school boy，Pasteur worked slowly and carefully．At first，his teachers thought that young Louis might be a slow learner．Through elementary school，high school，and college，Pasteur worked in the same thoughtful way．Then he became a college professor and a scientist，and he continued to work very carefully．
   Pasteur was studying about the germs（細菌）that cause rabies when Joseph Meister became ill．In fact，Pasteur believed he had a medical treatment for rabies，but he had never given it to a person before．At first，Pasteur was afraid to treat Joseph，but the poor child was dying．Pasteur gave Joseph an inoculation（預防接種）every day for ten days．Slowly，the child became better．
   During his lifetime，Pasteur studied germs and learned how they cause diseases in animals and people．He developed vaccinations（疫苗）that prevent many of these diseases．On September 28，1895，Louis Pasteur passed away，at the age of 72．The work of this great man has been of great help to modern medicine．
