Alexander Graham Bell

Alexander Graham Bell is known around the world for his invention of the telephone in 1876. He created many other innovative devices, including a gigantic man-lifting kite, a balancing rudder for airplanes, and a telephone probe to detect bullets in the human body. He would often get up in the middle of the night to work out a new idea, and once took apart his wife’s new venetian blinds in order to construct a propeller. Bell was a lecturer on vocal physiology at Boston University and a founder of the American Association for the Teaching of Speech to the Deaf.
