Henry who? When? Until today, I had never heard of Henry Sutton (1856-1912). He was an Australian inventor of telephones, lightbulbs, and yes, in 1885 he developed plans for a mechanical television that he called a telephane. It used no active elements or amplification of any sort. (Thermionic emission from a heated filament — “the Edison effect” — had just been discovered and the triode vacuum tube wasn’t invented until about 1910.)
In the drawing, note the oil lamp! This discussion reveals as much detail as I’ve found. I agree with the consensus that merely publishing a plan doesn’t qualify as “inventing” a device. Close, but no cigar. However, he certainly deserves a gold star for imagination and creativity.
The idea of a spinning opaque disc with a “window” was used in subsequent television designs, up through the original FCC-approved CBS color TV system c 1950!
