John Logie Baird (1888-1946), the Scottish electrical engineer and pioneer of television. The son of a presbyterian minister, Baird was educated in Glasgow. After a serious illness in 1922 he 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 giving the first BBC TV transmissions. He used a mechanical scanning system, with 240 lines by 1936, but then the BBC opted to use the Marconi-EMI electronic scanning system, with 405 lines. Baird also pioneered colour, stereoscopic and big screen TV, and ultra- short-wave transmission.
