When Helen Keller was 19 months old, she was stricken with an infectious disease that is now believed to be scarlet fever or meningitis. After struggling to live, Keller became blind and deaf because of the infection.

At the age of seven with the help of her teacher, Anne Sullivan, Keller was able to learn how to finger spell words while touching objects to build her vocabulary.
