Baird, John Logie (1888-1946), a Scottish engineer, gave the first public demonstration of a television technology that used mechanical devices in the camera and receiver. The demonstration took place in April 1925 in England.

In 1928, Baird broadcast pictures from London to New York. In 1929, the British Broadcasting Corporation (BBC) began regular experimental broadcasts using Baird’s technology. In 1937, however, the BBC selected a competing all-electronic system for its broadcasts. Baird had joined Philo T. Farnsworth, an American pioneer in all-electronic TV, to combine the two technologies. However, fire destroyed Baird’s laboratory before a merged system could be publicly tested. Baird was born on Aug. 13, 1888, in Helensburgh, Scotland. He died on June 14, 1946.
