Helen Keller lived in the USA. She was a great woman.
When Helen was a baby, she got very ill. After many weeks, the doctor said, "She is better, but now she can't see and she can't hear." Her mother and father were very sad.
A few years later, things got worse. There was no way for Helen to speak to other people. She heard nothing. She saw nothing. She didn't understand anything.
Then one day a teacher came to live with Helen and her family. The teacher helped Helen learn about words. Helen was a very clever girl and soon she learned to spell the first word. When she was older, she went to college.
Helen travelled around the world and helped many blind and deaf people. She became famous all over the world.
Helen was 88 years old when she died. The world remembers her today as a brave and wonderful person. She was blind and deaf, but she found a way to understand the world.
