MissSullivan was an extraordinary teacher. She touched the depths of Helen's soul andbrought light to her darkened world. She was a teacher at Perkins Institute. Mr. Anagnos offered her a teaching job to teach Helen. She was partially blind and had undergone treatment for the same. This was the reason she could understand Helen's needs so well.

The day she arrived at Helen's house, Helen called that day the most importantday of her life. Helen compared the arrival of her teacher to the shining of'light of love' in her darkened life.

Miss Sullivan took unprecedented pains toteach Helen manual alphabet. Since Helen was suffering from hearing as well asvisual disabilities, Miss Sullivan really had to work very hard to teach Helenthe alphabet. Initially Helen did not accept all her explanations, techniquesand methodology, but after Miss Sullivan won Helen’s confidence, Helen hadcomplete faith in her. Miss Sullivan understood Helen thoroughly. Sheknew how to make things clear to her. Whether it was teaching her thedifference between ‘w-a-t-e-r’ and ‘m-u-g’ or teaching her the word ‘d-o-l-l’for both the dolls, Miss Sullivan knew the methodology.
