No one actually invented the video phone. The combination of audio and images was first conceptualized in 1878. However, the technology to accomplish this feat did not exist.
The development of the video phone took a half century to get a working version. And another half century to make it usable.
Functional versions were developed by bell labs in the 1920's.
The Photophone, also known as a radiophone, was invented jointly by Alexander Graham BellHe said it was his greatest invention.It is a means of communication...through the transmission of light.
He invented the telephone, the photophone, and the original audiometer.

the photophone
yes Alexander graham bell invented the photophone along with the telephone which made his rich and famous very fast. It has been suggested that Elisha Gray invented the telephone and lodged his patent at the same office, and just before Bell. The diagrams on Bell's application, look uncannily like Gray's. Although Gray applied before Bell, the credit went to Bell.
A photophone is used to allow speech into a light beam. The invention was released in Feb. 19th, 1880 by Alexander Graham Bell.
I think it used only light to transmit messages instead of electricity... I could be wrong though you may want to try wikipedia
Very little, even today people do not really use videophones very often, even if their phones have the facility.
No, Alexander didn't think too highly of Deaf people, even though his wife was Deaf. Thomas Hopkins Gallaudet brought sign language from France (along with Laurent Clerc, a Deaf man, also French) to the United States.
He was given 18 patents in his name and 12 patents he shared with his callaborators. He was awarded with 14 patents for the telephone and telegraph, four for the photophone, one for the phonograph, five for aerial vehicles, four for hydroairplanes, and two for a selenium cell.
A list of the inventions I know of is: Telephone Graphaphone Wheat husker Photophone Metal detector Hydrofoil I may have missed some out, but I hope this helped anyway!
