Adriano de Paiva Issues the First Separate Publication on Television

In 1880 Adriano de Paiva, a professor of chemistry and physics at the Polytechnic Academy at Porto (Portugal) issued the first separate publication on television: La telescopie électrique basée sur l'emploi du selenium, a 48-page pamphlet published in Porto.

Paiva's paper represented the first theoretical formulation of the possibility of using selenium to transmit images at a distance. Paiva became interseted in the possibility of transmitting images by wire after the demonstration of Alexander Graham Bell's telephone in Lisbon in November 1877.
