Television was not invented by a single inventor, instead many people working together and alone, contributed to the evolution of TV.
1831: Joseph Henry's and Michael Faraday's work with electromagnetism makes possible the era of electronic communication to begin.
1862: Abbe Giovanna Caselli invents his "pantelegraph" and becomes the first person to transmit a still image over wires.
1873: Scientists May and Smith experiment with selenium and light, this opens the door for inventors to transform images into electronic signals.
1876: Boston civil servant George Carey was thinking about complete television systems and in 1877 he put forward drawings for what he called a "selenium camera" that would allow people to "see by electricity." Eugen Goldstein coins the term "cathode rays" to describe the light emitted when an electric current was forced through a vacuum tube.

Giovanni Caselli
Italian physicist (1815–1891)
Giovanni Caselli (8 June 1815 – 25 April 1891) was an Italian priest, inventor, and physicist. He studied electricity and magnetism as a child which led to his invention of the pantelegraph (also known as the universal telegraph or all-purpose telegraph), the forerunner of the fax machine. The world's first practical operating facsimile machine ("fax") system put into use was by Caselli. He had worldwide patents on his system. His technology idea was further developed into today's analog television.
Caselli was a student and professor at the University of Florence in Italy. He started a technical journal that explained physics in layman's terms. For his pantelegraph technology he was awarded the Legion of Honor by Napoleon III of France. Parisian scientists and engineers started the Pantelegraph Society to exchange ideas about the pantelegraph and the associated synchronizing apparatus, in order to get the sending and receiving mechanisms to work together properly.
Early life
[edit]Caselli was born in the town of Siena, Italy on 25 April 1815.[3] As a child, he was tutored in Florence by Italian physicist Leopoldo Nobili.[4] These studies involved electrochemistry, electromagnetism, electricity and
