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.
