Adriano de Paiva was a Portuguese
scientist
who was one of the pioneers of telectroscope
. He worked at the Politechnical Academy of Porto
and conducted research into selenium
as a material to transmit image
s.
His work followed the discovery of photoconductivity
in selenium
by Willoughby Smith
in 1873. In the 19thcentury he suggested the use of a chemical that would enable images to be transmitted at a considerable range.
