| | Telephone Introduction |
 | | Bell and his assistant, Charles Sumner Tainter, developed the photophone using a sensitive selenium crystal and a mirror that would vibrate in response to a sound. |
 | | Toward this end, in 1881, he used the $10,000 award for winning France's Volta Prize to set up the Volta Laboratory in Washington, D.C. A believer in scientific teamwork, Bell worked with two associates, his cousin Chichester Bell and Charles Sumner Tainter, at the Volta Laboratory. |
 | | His Family included: His uncle, David Charles Bell, his father Alexander Melville Bell, in-law's Hubbard, his brother Melville James Bell, his daughters Elsie May Bell and Marian Hubbard Bell. |
