While a teacher for the hearing impaired, Bell was asked by a group of investors — one of whom was his father-in-law Gardiner Hubbard — to help perfect the harmonic telegraph. The device was one of the most exciting innovations of the day, allowing for multiple messages to be sent over wire simultaneously.

But a few years after founding Bell Telephone Company, Bell quickly lost interest in managing the business aspect of his enterprise and sold his shares. In he invested his sizable fortune into building a new scientific experimental facility called the Volta Laboratory, aimed to improving the lives of the hearing impaired. The laboratory ran many experiments using light to transmit sound.
The graphophone was an improved and more commercialized version of the phonograph invented by Thomas Edison. After the fatal shooting of President James A. Garfield in , Bell got to work on a device that could detect metal in the body for surgical use. In the s, Bell began focusing his studies on aviation. Georgetown, Washington, D.

In Melville published his first works on Visible Speech , to help the deaf both learn and improve upon their aural speech since the profoundly deaf could themselves not hear their own aural pronunciations.
