Abbe Giovanna Caselli invents the Pantelegraph and becomes the first person to transmit a still image over wires
Scientists May and Smith start to experiment with selenium and light, this reveals the possibility for inventors to transform images into electronic signals
Eugen Goldstein coins the term “cathode rays” to describe the light emitted when electric current was forced through a vacuum tube
Inventors Alexander Graham Bell and Thomas Edison theorize about telephone devices that transmit image as well as sound.
Bell’s photophone used light to transmit sound but, he wanted to advance his device for image sending
Paul Nipkow sends images over wires using a rotating metal disk to move the picture. He calls it the electric telescope.
Russian Constantin Perskyi made the first known use of the word “television”
Two major paths of development of a television system were pursued by inventors
- Inventors attempted to build mechanical television systems based on Paul Nipkow’s rotating disks
- Inventors attempted to build electronic television systems based on the cathode rays developed interdependently in 1907 by English inventors A.A. Campell Swinton and Russian scientist Boris Rosing
Lee de Forest invents the Audion vacuum tube
This was the first tube with the ability to amplify signals
Boris Rosing combines Nipkow’s disk and a cathode ray tube and builds the first working mechanical TV system
John Baird becomes the first person to transmit moving silhouette images using a mechanical system based on Nipkow’s disk
Bell Telephone and the US Department of Commerce conduct the first long-distance use of television that took place between Washington D.C. and New York City on April 7th
“Today we have, in a sense, the transmission of sight for the first time in the world’s history. Human genius has now destroyed the impediment of distance in a new respect, and in a manner hitherto unknown” – Secretary of Commerce Herbert Hoover
