The Scots Television Pioneer
John Logie Baird (1888-1946) is often seen as a failed pioneer after the Marconi system won the contract from the BBC for general broadcasting. However Baird was a true pioneer in that he was the first person to produce a live televison picture.
He did this by using a better photoelectric cell and improving the signal conditioning from the photocell to the video amplifier. He started in February 1924 with a Nipkow disk and showed that a semi-mechanical analogue system was made possible by this and transmitted live pictures of silhouette objects in Selfridges department store in 1925.
At the end of 1925 he used the head of a ventriloquist's dummy called 'Stooky Bill,' as the object in a 30 line vertically scanned image, transmitted at five pictures a second. He fetched Willam Taynton from downstairs to see the image, then transmitted Taynton himself, who had the honour of being the first live person on televison.
Undettered by his failure to have his system adopted, Baird went on to create a colour tv system in 1939 and a high resolution system that would have been comparable to HDTV. The colour filter system was adopted in the USA. He also went on to create a live video recording system using a disk, so he was also the inventor of the first video.
He died of a stroke in Bexhill-on-Sea, a man who had been a successful and productive Scottish inventor.
