Who was the lady that was deaf and blind, and famously overcame those?

Might be Helen Keller, very famous deafblind activist. A quote from wikipedia kind of shows how hard communicating when senses are limited:

The next month, Keller made a breakthrough, when she realized that the motions her teacher was making on the palm of her hand, while running cool water over her other hand, symbolized the idea of “water”. Writing in her autobiography, The Story of My Life, Keller recalled the moment:

I stood still, my whole attention fixed upon the motions of her fingers. Suddenly I felt a misty consciousness as of something forgotten—a thrill of returning thought; and somehow the mystery of language was revealed to me. I knew then that w-a-t-e-r meant the wonderful cool something that was flowing over my hand. The living word awakened my soul, gave it light, hope, set it free!
