When Elizabeth Kenny was a little girl, she fell off a horse and hurt her arm. Mrs. Kenny took her to a doctor in Toowoomba, Queensland. In the doctor’s, Elizabeth saw many bottles of medicine standing in a row. Since then, she wanted to be a nurse. As soon as she was old enough, Elizabeth was trained in a hospital. After working for some time, she made a surprising discovery. Among her patients were some children who had lost the use of their legs because of polio ( 小儿麻痹症) . Kenny tried putting hot cloth on their legs and washing them in a special way. The results were great. The children were able to use their legs again.

  Most doctors would not believe that children could get well in such a simple way. Gradually, however, she became famous. From 1993 on people from many parts of the world brought their children to Australia to receive treatment by this wonderful nurse. She was invited to America where her methods were used in many hospitals. Money was collected to build Kenny foundations which were for polio patients. Kenny died in 1952, but she will long be remembered for her fight against polio.
