context_page_description: John Logie Baird FRSE was a Scottish inventor, electrical engineer, and innovator, demonstrating the world's first working television system on 26 January 1926. He also invented the first publicly demonstrated colour television system, and the first purely electronic colour television picture tube.
  In 1928 the Baird Television Development Company achieved the first transatlantic television transmission. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history.
  During 2006, Baird was named as one of the 10 greatest Scottish scientists in history, having been listed in the National Library of Scotland's 'Scottish Science Hall of Fame'. In 2015 he was inducted into the Scottish Engineering Hall of Fame. On the 26 January 2017 – IEEE unveiled a bronze street plaque at 22 Frith Street, London, dedicated to Baird and the invention of television.
context_section_description: On 26 January 1926, Baird repeated the transmission for members of the Royal Institution and a reporter from The Times in his laboratory at 22 Frith Street in the Soho district of London, where Bar Italia is now located. Baird initially used a scan rate of 5 pictures per second, improving this to 12.5 pictures per second c.1927. It was the first demonstration of a television system that could broadcast live moving images with tonal graduation.
  He demonstrated the world's first colour transmission on 3 July 1928, using scanning discs at the transmitting and receiving ends with three spirals of apertures, each spiral with a filter of a different primary colour; and three light sources at the receiving end, with a commutator to alternate their illumination. The demonstration was of a young girl wearing different coloured hats. Noele Gordon went on to become a successful TV actress, famous for the soap opera Crossroads. That same year he also demonstrated stereoscopic television.
