The eerie image … shows the first image to ever be transmitted onto television. The year was 1926, and Scottish inventor John Logie Baird had successfully broadcast his business partner’s face through an apparatus he dubbed “the televisor”, which was of course the early version of all television sets today.
I’m guessing that’s a still from a 16mm test film, or perhaps it wasn’t animated at all and it was just a flickering image transmitted to a small (3.5″ x 2″) video display.
Another source includes this commentary:
One staff member quoted [the Editor of the London Daily Press] as saying: “For God’s sake, go down to the reception and get rid of a lunatic who’s down there. He says he’s got a machine for seeing by wireless. Watch him – he may have a razor on him.”
Following his demonstration in 1926, Baird developed colour TV and brought out the world’s first mass produced television set in 1929.
