John Logie Baird

John Logie Baird (b. August 13, 1888, d. June 14, 1946) of Scotland (University of Glasgow) was the first to invent a working system of television capable of showing moving images with shades of grey. Baird demonstrated his system to the Royal Institution[?] and a reporter from The Times on January 26, 1926 in the Soho district of London.

From 1929 onwards, the BBC made broadcasts using the Baird television system, alternating these with broadcasts of electronic scanning system television signals during the 1930s, until it finally discontinued broadcasts of the Baird system in 1937.

Baird's mechanical television system was replaced by the electronic television system described by A.A. Campbell-Swinton[?] and later developed by inventors such as Philo T. Farnsworth and Vladimir Zworykin.
