John Logie Baird (1888-1946), British electrical engineer, inventor and television pioneer. Baird was educated in Glasgow, Scotland. Following much experimentation, he developed a crude TV apparatus in 1922, able to transmit a picture and receive it over a range of a few feet. It was shown in Soho, London, England, in 1926, and by 1929 Baird was involved with early TV transmissions by the BBC. Baird's system used a mechanical spinning disc to scan 240 lines for each picture. His system was displaced by the Marconi-EMI electronic scanning system with 405 lines. Baird also pioneered colour TV, and stereoscopic and big screen TV, as well as ultra-short wave transmission.
