via Wikipedia: John Logie Baird · see source
John Logie Baird, a Scottish inventor and electrical engineer, is best known for unveiling the world’s first working mechanical television system on 26 January 1926. He later created the first colour television system shown to the public and the first practical all-electronic colour television picture tube. In 1928, his company, the Baird Television Development Company, sent the first television signal across the Atlantic. These achievements, along with his role in bringing broadcast television into homes, have secured his place in the history of the medium. Over the years, he has been recognised as one of the ten greatest Scottish scientists (2006), inducted into the Scottish Engineering Hall of Fame (2015), honoured with an IEEE street plaque in London (2017), and featured on a Royal Mint 50p coin (2021).
Baird was born on 13 August 1888 in Helensburgh, Dunbartonshire, the youngest of four children. His father was a Church of Scotland minister, and his mother was the orphaned niece of a wealthy Glasgow shipbuilding family. He attended Larchfield Academy, the Glasgow and West of Scotland Technical College, and the University of Glasgow, where his engineering course included apprenticeships. The harsh industrial conditions in Glasgow shaped his socialist views and worsened his health. He became agnostic, but this did not harm his relationship with his father. His studies were cut short by the First World War, and he never graduated. In early 1915, he volunteered for the British Army but was deemed unfit for active duty, so he took a munitions-related job with the Clyde Valley Electrical Power Company.
In early 1923, in poor health, Baird moved to Hastings on England’s south coast, later renting a workshop in the town’s Queen’s Arcade. Using items like an old hatbox, scissors, darning needles, bicycle light lenses, a tea chest, sealing wax, and glue, he built the world’s first working television set. In February 1924, he showed the *Radio Times* that a semi-mechanical analogue television system could transmit moving silhouette images. That July, he survived a 1000-volt electric shock with only a burnt hand, after which his landlord asked him to leave. After moving to London, he tried to promote his invention at the *Daily Express*, but the news editor, fearing a madman, ordered staff to get rid of him. Baird experimented with the Nipkow disk, a scanning system patented in 1884, which television historian Albert Abramson called “the master television patent.” On 2 October 1925, Baird transmitted the first television picture with greyscale—a 32-line vertical scan of a ventriloquist’s dummy named “Stooky Bill” at five frames per second. He then brought in office worker William Edward Taynton, who became the first person televised in full tonal range. In June 1924, Baird bought thallium sulfide from Cyril Frank Elwell, a chemical key to “talking pictures.” By cooling the cell and designing his own video amplifier, he produced the first live animated image from reflected light, pioneering technology still used today.
Baird gave the first public demonstration of moving silhouette images by television at Selfridges department store in London for three weeks starting 25 March 1925. On 26 January 1926, he showed true television images to members of the Royal Institution and a *Times* reporter at his laboratory at 22 Frith Street in Soho (now the site of Bar Italia). Initially scanning at five pictures per second, he improved this to 12.5 by about 1927. This was the first demonstration of a system that could scan and display live moving images with tonal graduation. On 3 July 1928, he demonstrated the world’s first colour transmission, using scanning discs with three spirals of apertures, each with a different primary colour filter, and three light sources at the receiver. That same year, he also showed stereoscopic television.
In 1927, Baird transmitted Britain’s first long-distance television pictures over 438 miles of telephone line between London and Glasgow Central station.

Verified Timeline
Lore & Background
Baird was born on 13 August 1888 in Helensburgh, Dunbartonshire, the youngest of four children of the Reverend John Baird and Jessie Morrison Inglis. He was educated at Larchfield Academy, the Glasgow and West of Scotland Technical College, and the University of Glasgow. His degree course was interrupted by the First World War and he never returned to graduate. In early 1923, in poor health, he moved to Hastings, where he built what became the world's first working television set using items including an old hatbox, a pair of scissors, darning needles, bicycle light lenses, a used tea chest, sealing wax, and glue. On 2 October 1925, he successfully transmitted the first television picture with a greyscale image: the head of a ventriloquist's dummy nicknamed 'Stooky Bill' in a 32-line vertically scanned image at five pictures per second. He then fetched office worker William Edward Taynton, who became the first person to be televised in a full tonal range. On 26 January 1926, Baird gave the first public demonstration of true television images for members of the Royal Institution and a reporter from The Times in his laboratory at 22 Frith Street in London. He demonstrated the world's first colour transmission on 3 July 1928, using scanning discs with three spirals of apertures and filters of different primary colours. In 1928, the Baird Television Development Company achieved the first transatlantic television transmission, from London to Hartsdale, New York. From 1929 to 1935, the BBC transmitters broadcast television programmes using the 30-line Baird system. On 2 November 1936, the BBC began alternating Baird 240-line transmissions with EMI's electronic scanning system, but ceased broadcasts with the Baird system in February 1937, due in part to a disastrous fire in the Baird facilities at Crystal Palace.
Reader's Guide
John Logie Baird's significance lies in his pioneering role in the practical introduction of broadcast television for home entertainment. His demonstration of the first mechanical television system on 26 January 1926 marked a crucial step in the development of television technology. He also achieved the first transatlantic television transmission in 1928 and the first colour television demonstration on 3 July 1928. Although his mechanical system was eventually replaced by fully electronic systems developed by EMI-Marconi under Sir Isaac Shoenberg, his early work laid the foundation for television broadcasting. Baird's legacy is recognized through honors: in 2006 he was named one of the 10 greatest Scottish scientists in history, listed in the National Library of Scotland's 'Scottish Science Hall of Fame'; in 2015 he was inducted into the Scottish Engineering Hall of Fame; in 2017 IEEE unveiled a bronze street plaque at 22 Frith Street, London, dedicated to Baird and the invention of television; and in 2021 the Royal Mint unveiled a John Logie Baird 50p coin commemorating the 75th anniversary of his death.

Common Misconceptions (Editorial)
Some people believe Baird invented the first fully electronic television system, but his early successes were with mechanical television, using spinning discs. While Baird demonstrated the first color transmission in 1928, his system was not purely electronic; the first viable purely electronic color television picture tube was a later Baird innovation. Another misconception is that Baird’s television work ended after the BBC switched to EMI’s electronic system in 1937, but he continued to develop key technologies afterward.
Why It Matters (Editorial)
John Logie Baird matters because he transformed a scientific curiosity into a home entertainment reality, proving that moving images could be transmitted and received by the public. His resourcefulness—building the first working television from scrap materials—reminds us that groundbreaking innovation often begins not in a pristine lab, but with a hatbox, a tea chest, and sheer determination.
