Read the excerpt from The Story of My Life by Helen Keller. Dr. Bell advised my father to write to Mr. Anagnos, director of the Perkins Institution in Boston, the scene of Dr. Howe's great labours for the blind, and ask him if he had a teacher competent to begin my education. This my father did at once, and in a few weeks there came a kind letter from Mr. Anagnos with the comforting assurance that a teacher had been found. This was in the summer of 1886. But Miss Sullivan did not arrive until the following March.
