Read the excerpt from The Story of My Life by Helen Keller. She had read his account of Laura Bridgman, and remembered vaguely that she was deaf and blind, yet had been educated. But she also remembered with a hopeless pang that Dr. Howe, who had discovered the way to teach the deaf and blind, had been dead many years. His methods had probably died with him; and if they had not, how was a little girl in a far-off town in Alabama to receive the benefit of them?
