Baird, John Logie 1888-1946. Scottish
electrical engineer who pioneered television.
In 1925 he gave the first public
demonstration of television and in 1926
pioneered fibre optics, radar (in advance of
Robert Watson- Watt), and `noctovision', a
system for seeing at night by using infrared
rays. Born at Helensburgh, Scotland, Baird
studied electrical engineering in Glasgow at
what is now the University of Strathclyde, at
the same time serving several practical
apprenticeships. He was working on television
possibly as early as 1912, and he took out
his first provisional patent 1923. He also
developed video recording on both wax records
and magnetic steel discs (1926-27), colour TV
(1925-28), 3-D colour TV (1925-46), and
transatlantic TV (1928). In 1936 his
mechanically scanned 240-line system competed
with EMI-Marconi's 405-line, but the latter
was preferred for the BBC service from 1937,
partly because it used electronic scanning
and partly because it handled live indoor
scenes with smaller, more manoeuvrable
cameras. In 1944 he developed facsimile
television, the forerunner of Ceefax, and
demonstrated the world's first all-electronic
colour and 3-D colour receiver (500 lines).
He also developed video recording on both wax
records and magnetic steel discs (1926-27),
colour TV (1925-28), 3-D colour TV (1925-46),
and transatlantic TV (1928). In 1944 he
developed facsimile television and
demonstrated the world's first all-
electronic colour and 3-D colour receiver
(500 lines).
