A letter to Annie Sullivan, 2 April 1903, from Alexander Graham Bell.
What's interesting about this is Bell's backstory and his extensive personal and professional history of working with the deaf.
Both his mother and his wife were deaf, and it was his research into speech development and sound production (i.e. hearing devices) that led to his invention of the telephone. His father, grandfather and brother were all elocutionists, and as a tutor at his father's school for the deaf, he worked with Helen Keller.
