Other then these stupid definitions here whatever they mean, Helen Kellen was a woman who was blind and deaf since she was nineteen months of age which could have started by some kind of Scarlett fever. Annie Sullivan was the teacher to brake through her isolation, like in the movie the miracle worker which is based on her true story. She campaigned for woman's suffrage,workers' rights, and socialism. Was born June 27 1880 and lived to June 1st 1986.
Helen Keller was a great historical person and she was really blind and deaf and achieved a lot through out her life.
