“2nd October, 1925 - success! Everything functioned properly. The image of the dummy's head formed itself on the screen, with, what appeared to me, almost unbelievable clarity”. Immediately after this, he used the office boy, William Taynton, as a human subject. This event - the first ever transmission of a proper television picture, is commemorated by a blue plaque mounted on the wall of his old workshop at 22 Frith Street, Soho, London. | “2nd October, 1925 - success!

|a5=Communication – the birth of visual picture and image transmissions world wide – One of the most significant changes to society in the 20th century - socially giving the world much a more effective communication means within and between the nations allowing new types of information to be exchanged. Many Technological and Engineering aspects such as electronic cameras and displays had to be solved by piecemeal inventions to allow the successful achievement and adoption of Broadcast Television. Various scientific principles behind this work were poorly understood at the time such as selenium cell behaviour. This led to progress in these aspects as well as discovery of subsidiary effects, for instance infra red viewing (christened Noctovision by Baird) and radar. Suitable transmission methods had to be established. All in all the social affects have been enormous and changed the world. | “26th January, 1926 – he gave a private demonstration to Royal Institution members”.|a5=Communication – the birth of visual picture and image transmissions world wide – One of the most significant changes to society in the 20th century - socially giving the world much a more effective communication means within and between the nations allowing new types of information to be exchanged.

Transmission of pictures and moving images over large distances. Much higher speed of information transfer compared to other methods (postal). Transmission of action (realising visualisation as if you were present at the scene). Other key features that set this work apart was the added advantage of reception by numerous, widespread recipients (eventually worldwide). Initially, normal telephone lines were used for large distance transmission (as in JLB first demonstration in 1927 of transmission from London to Glasgow) before wireless transmission gave television much wider international capability. In February 1928 Baird sent television images from London to Hartsdale, NY, just north of New York City. | Transmission of pictures and moving images over large distances.

Key technological features were the use of scanned image strips of the picture being sent and received consecutively, initially utilising mechanically rotating discs with apertures to split down the image. Later, working privately during World War II, John Logie Baird developed improved electronic television based on scanning with cathode ray tubes. Baird’s work led eventually to further advances including the rapid electronic transmission of still images (fax), 3-dimensional television and large-screen television. | Key technological features were the use of scanned image strips of the picture being sent and received consecutively, initially utilising mechanically rotating discs with apertures to split down the image.

John Logie Baird’s inventiveness and engineering abilities led to him taking out patents in a range of fields. All in all he has achieved 178 patents down to his name. Most of them were either British or US. There is a full list given in Professor Russell Burns's book: (Burns, R. - John Logie Baird, television pioneer, ISBN-10: 0-85296-797-7. | </p> | ||
|a6=Realisation of new techniques and improvement of technology were some of the technical obstacles that needed solutions. Light, how to provide more light was the most serious problem. The photoelectric cells then available were quite unresponsive to the light. | John Logie Baird’s inventiveness and engineering abilities led to him taking out patents in a range of fields.

Radio Transmission Licences and Commercial broadcast licences had to be acquired and renewed. In Britain, the B.B.C. had to be persuaded to broadcast television programmes; at first, Baird’s company had to pay the B.B.C. for the use of its transmitting facilities. | Radio Transmission Licences and Commercial broadcast licences had to be acquired and renewed.

Commercial stealing of ideas had to be dealt with –with its legal inferences and consequences. Finance was not readily forthcoming and had to be found - undoubtedly slowed down this technological advance. Human acceptance of the idea of television was slow and it often delayed the development of the inventions. | </p> | ||

N.B. [JLB’s first television company – “Television Limited”- dates from 1926. Then there were several other Baird companies which were amalgamated in 1930 to form "Baird Television Ltd" which lasted until 1939. The company moved out of Long Acre in about 1934]. In September 1939 broadcast television was shut down and Baird Television Ltd. Went into receivership. However, Baird continued his research independently. | N.B.

a. JLB’s workplace in Hastings where he sent crude 30 line silhouettes, first confirming to himself that television was possible, already has a plaque, at the Queen’s Arcade in the centre of the town. There is one also at 21 Linton Crescent, the house in Hastings where he lodged. (www.discoverbexhill.com) | a.

g. There is a bronze bust of John Logie Baird on a plinth in West Clyde Street overlooking the Firth of Clyde. There is a commemorative stained glass window in the West Parish Church. At the University of Strathclyde there is a plaque outside the department of Electrical Engineering. Until a couple of years ago, one of their halls of residence was called Baird Hall. However the building has now been sold. The museum that links with Strathclyde University holds many of John Logie Baird’s manuscripts. | g.

The Crystal Palace tower and buildings were destroyed by fire in 1936 but the building adjacent – which at that time was also used by John Logie Baird for this work - is still standing. It is now a Museum of Crystal Palace historical artefacts, housing some references and artefacts of his work and activity at Crystal Palace. The site has large parkland around it (currently used for a multitude of activities) and also this site now has an LDA development plan for it which has recently been approved. This will bring Crystal Palace into an active site with many visitors. The Museum will be rebuilt and can possibly house the IEEE Plaque to good effect with JLB information set alongside it. This should make it most appropriate with the prospect of many visitors and well protected. | The Crystal Palace tower and buildings were destroyed by fire in 1936 but the building adjacent – which at that time was also used by John Logie Baird for this work - is still standing.

The Crystal Palace Museum staff is also very supportive of an IEEE MILESTONE Plaque for JLB and would welcome this addition in order to add to the Museum and the display relating to JLB – the Museum Curator and Museum trustees have been sent requests for support in writing. | </p> | ||
