John Logie Baird
1888–1946 · Engineer and Inventor
A Scottish engineer and inventor who pioneered mechanical television and gave a landmark public demonstration of recognisable televised moving faces in 1926.
“Seeing is, in a sense, believing, and believing is seeing.”
Why is this scientist famous?
Pioneering early television and giving a landmark public demonstration of recognisable moving television images in London in 1926, followed by major experiments in long-distance, colour and stereoscopic television.
John's story
A Sickly Boy with Big Ideas
John Logie Baird was born in 1888 in Helensburgh, a small town on the west coast of Scotland. His father was a minister in the local church. As a child, John was often ill — he suffered from poor health throughout his life — but he had a restless, inventive mind. He rigged up a primitive telephone exchange between his bedroom and a friend's house using wires strung across the street, and he built a small electric lighting system for his father's house. He studied electrical engineering at what is now the University of Strathclyde, but his studies were cut short by the First World War. He tried to enlist but was rejected because of his health. He spent the war years working for an electrical company, then tried his hand at a series of failed businesses: he set up a jam factory in Trinidad, tried to make soap, and attempted to sell socks. None of them succeeded. But Baird had one idea that would not leave him alone: the idea of transmitting moving pictures through the air.
Television from a Hat Box
In the 1920s Baird experimented with television using improvised equipment such as a tea chest, lenses and a rotating scanning disc based on an earlier concept patented by Paul Nipkow. At Selfridges in London in 1925 he demonstrated a shadowgraph that transmitted silhouettes rather than recognisable faces. Later that year he succeeded in transmitting moving images with shades of grey. On 26 January 1926 he publicly demonstrated his television system.
The First Public Demonstration
On 26 January 1926, Baird demonstrated recognisable televised moving faces to members of the Royal Institution at his laboratory in Frith Street, Soho. Other inventors had already experimented with television and transmitted simpler images, but Baird's demonstration was an important milestone in showing recognisable live human images. In 1928, Baird achieved the first transatlantic television transmission, sending an image from London to New York. In 1928 he demonstrated an early mechanical colour television system and stereoscopic television. The BBC began broadcasting television using Baird's system in 1929, and for several years his mechanical system was the only way to see television. But by the mid-1930s, a rival electronic system developed by the Marconi-EMI company was proving far superior, producing clearer pictures with no moving parts. In 1937, the BBC switched to the electronic system, and Baird's mechanical television was retired. It was a bitter blow, but Baird did not give up — he continued developing colour television and large-screen projection systems from his own laboratory.
A Visionary Who Died Too Soon
Baird continued to innovate into the 1940s. He demonstrated a colour television system that was remarkably advanced for its time, and he developed a high-definition colour system that would not be commercially realised for decades. But his health, always fragile, was failing. He suffered a stroke in 1946 and died in June of that year, aged fifty-seven. He did not live to see television become the dominant form of entertainment in the world. Today, his house in Hastings bears a blue plaque, and a statue of him stands in Helensburgh. He is remembered as one of the major pioneers of early television, whose mechanical systems demonstrated recognisable moving images and helped show television's possibilities before electronic systems became dominant.
What did they discover?
Landmark Television Demonstration
On 26 January 1926 Baird demonstrated recognisable moving human faces by television to members of the Royal Institution in London, an important milestone in the development of television.
First Transatlantic Television Transmission
In 1928, Baird transmitted a television image from London to New York — the first time a picture had crossed the Atlantic by wireless, proving television could work over long distances.
Early Colour and Stereoscopic Television
In 1928 Baird demonstrated a mechanical colour television system and also demonstrated stereoscopic television.
Large-Screen Projection Television
In the 1940s, Baird developed a large-screen colour television projection system that was far ahead of its time, anticipating technologies that would not be commercially realised for decades.
Amazing facts
Baird's early television experiments used improvised materials including a tea chest, darning needles, bicycle lenses, glue and sealing wax.
Baird used dummy heads during some early television experiments because they could remain motionless under the intense lighting his equipment required.
His first public television demonstration in 1926 produced an image about the size of a postcard.
He sent the first transatlantic television transmission from London to New York in 1928.
He demonstrated both colour television and 3D television in 1928, decades before they became practical.
His mechanical television system was replaced by the electronic Marconi-EMI system in 1937 — but he kept inventing colour systems right up to his death.
