American electrical engineer born in Edinburgh, Scotland, who invented the first television prototype (1911). He began his career as a media researcher (1883) in Newcastle, following the guidance of William George Armstrong. Working in London, he pioneered the medical application of radiography (1896) when he opened the first radiography laboratory in Britain. From then onwards, he dedicated himself to research on electronic television systems, obtaining his first results about ten years later.
Independently, he and Russian Boris Rosing suggested the use of cathode rays to reproduce images on a phosphor screen (1907). The idea of filmless photography, that is, the famous digital cameras, originated in this engineer's head. He proposed (1908) a way to capture images electronically in an article published in the journal Nature and three years later (1911) he published a series of schematics of the functioning of his ideas, technically creating the concept of television.
In his time, technology was not enough to materialize his project, which could only become a reality after World War II. His system is basically the same one that is still used on televisions today, which is an efficient means of capturing still and moving images with synchronized sound, without film, of course. He was elected a Fellow of the Royal Society (1915).
