1st test of a working television, October 2, 1925

-October 02, 2017

John Logie Baird, a Scottish engineer and inventor, performed the first test of a working television system on October 2, 1925.

He did so in his London lab, where he successfully transmitted the first television picture with a greyscale image: the head of a ventriloquist's dummy in a 30-line vertically scanned image, at five pictures per second.

Upon that success, Baird called in an office worker, 20-year-old William Edward Taynton, so that he could see what a human face would look like televised. Taynton became the first person to be televised in a full tonal range.

Baird was eager to share the news of this accomplishment with the masses. He went to the office of his local daily newspaper to promote his invention. The news editor was terrified of his claims, described Baird as a lunatic who said he had a machine for seeing by wireless, and told reception to be cautious of him because he could be armed with a razor and violent.

Baird did manage to get media attention in January 1926, when he repeated the transmission for members of the Royal Institution and a reporter from The Times in his laboratory. By this time, he had improved the scan rate to 12.5 pictures per second. It was the first demonstration of a television system that could broadcast live moving images with tone graduation (See photo of Baird working on his transmitting station in his laboratory around 1926).

He went on to demonstrate the world's first color transmission in 1928 and in 1932, he became the first person in Britain to demonstrate ultra-short wave transmission.

Although Baird's electromechanical system was eventually displaced by purely electronic systems (such as those of Vladimir Zworykin, Marconi-EMI, and Philo Farnsworth), Baird's early successes earned him a prominent place in television's invention.

In 2016, the 1926 Royal Institution demonstration was honored with this Google Doodle:
