John Logie Baird. Artwork of the Scottish electrical engineer and television (TV) pioneer, John Logie Baird (1888-1946) carrying out an experiment. He is 'sending an outline of his hand by radio', an early experiment in TV transmission. The son of a presbyterian minister, Baird devoted himself to experimentation and developed a crude TV apparatus able to transmit a picture and receive it over a range of a few feet. By 1929 his company was involved with early TV transmiss- ions. He used a mechanical scanning system with 240 lines by 1936, but his system was displaced by the Marconi-EMI electronic scanning system with 405 lines.
