Born in Helensburgh, Dumbartonshire, John Baird was an engineer who
pioneered the development of television. Plagued with ill health (he’d
been rejected as unfit for military service for WW1) he was forced to
resign from his position as an electrical engineer, and retired early
in 1922 to Hastings on the English South coast, there he used his time to research ways
of transmitting pictures.
Although other scientists around the world were also conducting
experiments at the same time, Baird was the first to hold a successful
public demonstration, this was on January 27, 1926 in London using his
primitive television system. Later that year he also became the first to
transmit pictures of moving objects at the Royal Institution in London
in front of fifty scientists.
Continuing his research he transmitted pictures between London and
Glasgow using telephone lines in 1927, and between London and New York
in 1928 using radio waves. He also helped to pioneer colour television
and stereoscopic television - a system giving greater depth to the
picture. Baird’s company, Baird Television Development Company, provided
the first programme for the British Broadcasting Corporation (BBC) on
September 30, 1929.
The first television systems transmitted pictures made up of only 30
lines. However, Baird was instrumental in using more lines and therefore
developed a more complex system that gave the picture greater
definition. Eventually, his mechanical system having 240-lines was
superseded by the electronic system invented by EMI in conjunction with
Marconi. Today television pictures consist of between 525 and 819 lines.
John Logie Baird died in Sussex, England on the 14th June 1946.
