Helen Keller was born in Alabama in 1880 and died in 1968. When she was only 19 months old, she got a fever that left her blind and deaf. When she was seven years old, her parents invited a teacher to teach Helen. Helen quickly learned how to read and write, and began to speak at the age of 10. When she was 20, she went to college. With the help of her teacher, she got a bachelor’s degree four years later.
Helen Keller devoted her life to helping the disabled and wrote a number of inspiring books. She traveled to many countries to give lectures. She set a good example to all of us, especially the disabled.
