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 | |
