He and his assistant, Charles Tainter, developed a device they called the "photophone," which transmitted sound on a beam of light. While recovering, he discovered his wife had sold everything in his lab for $6. [41] Throughout late 1867, his health faltered mainly through exhaustion.

In the bedroom, his assistant Watson waited with a reed receiver pressed against his ear.

This made the telephone practical for longer distances, and it was no longer necessary to shout to be heard at the receiving telephone. Bell, however, was struck by how sound waves on a membrane could move the components of the machine. Bell understood that if sound could be transmitted as an electrical current, it would be possible for a receiver to interpret those vibrations. However, Antonio Meucci also developed a talking telegraph, called. [122][123][124] This did not put an end to the still-contentious issue.

Alexander Graham Bell, one of the fathers of the telephone The Volta Laboratory became an experimental facility devoted to scientific discovery, and the very next year it improved Edison's phonograph by substituting wax for tinfoil as the recording medium and incising the recording rather than indenting it, key upgrades that Edison himself later adopted. To give the organization scientific credibility, Davenport set up a Board of Scientific Directors naming Bell as chairman.
