Alexander Graham bell invents the telephone
By 1874, Bell 's work on the harmonic telegraph had entered a formative stage with progress it made both at his new Boston "laboratory" as well as at his family home in Canada a big success. While working in Brantford, Bell experimented with a "phonautograph". Bell thought it might be possible to generate undulating electrical currents that corresponded to sound waves. But he had no working model to demonstrate the feasibility of these ideas. In 1874, Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to lessen the great cost of constructing new lines. When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell 's experiments. Patent matters would be handled by Hubbard 's patent attorney, Anthony Pollok. In March 1875, Bell and Pollok visited the famous scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry 's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Henry said that Bell had "the germ

Bibliography: 3 On March 10, 1876, three days after his patent was issued, Bell succeeded in getting his telephone to work, using a liquid transmitter similar to Gray 's design B. Later public demonstrations 1) The telephone was publicly exhibited on May 4, 1877 at a lecture given by Professor Bell in the Boston Music Hall.
