John Logie Baird was born in Helensburgh, Scotland to Reverend John Baird and Jessie Morrison Inglis in 1888.

Television Innovations
His interest in the idea of transmitting moving pictures became an obsession by 1923, when he turned to the project almost full time. Drawing on new developments in the field of electronics, he invented a system of mechanical television, the first such successful system that could actually broadcast images over space. Rather than being based on a cathode ray tube and vacuum tube camera, Baird relied on a Nipkow disc (a perforated, rotating disc) to disaggregate the televised image and reassemble it for view. An important new feature of the Baird system, given that radio broadcasting had recently appeared, was that it transmitted its signal by wireless, making mass distribution of televised images seem possible for the first time.
He made steady progress, transmitting the outline of objects by 1924, and recognizable faces by 1925. His 1926 demonstration of televised moving objects to the Royal Institution in London was the first such demonstration on record. That year, he also invented the “noctovisor”, which used infrared light to make objects visible in the dark or through fog. The main “Televisor” project continued to make headway. By 1927 he had successfully transmitted moving images over telephone wires between London and Glasgow and formed the Baird Television Development Company.

As his technology improved, resolution rose from 30 lines of definition to 240. That year, his Televisor went on sale to the public.
By the mid-1930s, however, his partially mechanical system was being challenged by all-electric systems. Although he had begun working on an all-electric system of his own, it was not far enough along to commercialize, and his decision to pursue his semi-mechanical system with the BBC precipitated the end of Baird’s competitiveness.

Baird died on 14 June 1946 in Bexhill-on-Sea in the UK.
