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 |
