Helen Keller met her teacher Anne Sullivan through contact with Alexander Graham Bell. His invention of the telephone was the result of his research into helping the deaf.
Oh, and it was Watson who invented the phone booth. His landlady was complaining about all the racket (having to shout into the primitive contraption). So he rolled up some blankets into a tent of sorts and voila!
“Helen Keller met her teacher Anne Sullivan through contact with Alexander Graham Bell.”
I did not know that.
