The Scottish inventor Alexander Bain introduced the facsimile machine between 1843 and 1846. Willoughby Smith, an English electrical engineer, discovered the photoconductivity of the element selenium in 1873. This schematic shows the circular paths traced by the holes, which may also be square for greater precision. The area of the disk outlined in black shows the region scanned. As a 23-year-old German university student, Paul Julius Gottlieb Nipkow proposed and patented the Nipkow disk in 1884.

This was a spinning disk with a spiral pattern of holes in it, so each hole scanned a line of the image. The first demonstration of the instantaneous transmission of images was by Georges Rignoux and A. A matrix of 64 selenium cells, individually wired to a mechanical commutator, served as an electronic retina. By the 1920s, when amplification made television practical, Scottish inventor John Logie Baird employed the Nipkow disk in his prototype video systems. He created his prototype in a little village called Santa Cruz on the island of Trinidad where he was recovering from an illness. He had also started work on the first color television. London and New York, and the first shore-to-ship transmission.
