John Logie Baird
John Logie Baird was a Scottish engineer, innovator and inventor of the world's first mechanical television the first publicly demonstrated color television system; and the first purely electronic color television picture tube. 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.
In 2002, Baird was ranked number 44 in the BBC's list of the "100 Greatest Britons" following a UK-wide vote. In 2006, Logie 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' .
Early Life
John Logie Baird was born on 14 August 1888 in Helensburgh on the west coast of Scotland, and was the youngest of four children of the Reverend John Baird, the Church of Scotland's minister for the local St Bride's church and Jessie Morrison Inglis, the orphaned niece of a wealthy family of shipbuilders from Glasgow . He was educated at Larchfield Academy in Helensburgh; the Glasgow and West of Scotland Technical College and the University of Glasgow. His degree course was interrupted by World War I and he never returned to graduate.
Invention of Television
Baird was not the first one who tried to invent television , Baird made major advances in the field, and Many historians credit Baird with being the first to produce a live, moving, greyscale television image from reflected light. Baird achieved this, where other inventors had failed, by obtaining a better photoelectric cell and improving the signal conditioning from the photocell and the video amplifier.
Baird managed to use Arthur Korn’s Invention " signal-conditioning circuits for image transmission "
Korn's compensation circuit allowed him to send still fax pictures by telephone or wireless between countries and even over oceans, while his circuit operated without benefit of electronic amplification.
Then In his first attempts to develop a working television system, Baird experimented with theNipkow disk. When the war ended he set himself up in business, with mixed results.
Baird then moved to the south coast of England and applied
himself to creating a television, His first crude apparatus was
made of odds and ends, but by 1924 he managed to
transmit a flickering image across a few feet. On 26 January 1926 he gave the world's first demonstration of true television . In 1927, his television was demonstrated over 438 miles of telephone line between London and Glasgow, and he formed the Baird Television Development Company.
(BTDC). In 1928, the BTDC achieved the first transatlantic television transmission between London and New York and the first transmission to a ship in mid-Atlantic. He also gave the first demonstration of both colour and stereoscopic television.
Baird died on 14 June 1946 in Bexhill-on-Sea in Sussex.
