Sir Isaac Shoenberg (1 March 1880 – 25 January 1963) was a British electronic engineer born in Belarus who was best known for his role in the history of television. He was the head of the EMI research team that developed the 405-line (Marconi-EMI system), the first fully electronic television system to be used in regular broadcasting when it was introduced with the BBC Television Service in 1936. It was later adopted by other TV organizations around the world. As the head of research at EMI, Schoenberg was Alan Blumlein's supervisor when Blumlein invented stereophonic sound in 1931. Schoenberg was awarded the IET Faraday Medal by the British Institution of Electrical Engineers in 1954 and was knighted by Queen Elizabeth II in 1962.

David Shoenberg
David Shoenberg, MBE FRS, (4 January 1911 – 10 March 2004) was a British physicist who worked in condensed matter physics. Shoenberg is known for having developed experimental and theoretical principles to study the De Haas–Van Alphen effect to characterize the electrical conduction of metals. Biography David Shoenberg was the fourth of five children of Isaac (later Sir Isaac) Shoenberg, engineer and pioneer of radio and television, and Esther (née Aisenstein). He was born in St. Petersburg, but came to England with the family when he was three.

First Day Of Television Programmes
The first scheduled, high-definition (as then defined; meaning 240-line) television programmes were broadcast on 2 November 1936 by the British Broadcasting Corporation. They had been preceded by a number of low-definition BBC test broadcasts, as well as a 180-line Deutscher Fernseh Rundfunk service, from Berlin, since March 1935. Background The British Broadcasting Corporation, already an established radio broadcaster, began making low definition (30-line) test television transmissions under government licence in August 1936. These included short ad-hoc performances by musicians, with the duration limited as "lookers in" (as viewers were called) were found to experience eye strain through looking at the small screens then in use. The first regular electronic television service in Germany began in Berlin on 22 March 1935, as Deutscher Fernseh Rundfunk. Broadcasting from the Fernsehsender Paul Nipkow, it used a 180-line system, and was on air for 90 minutes, three times a week ...

Alexandra Palace
Alexandra Palace is a Grade II listed entertainment and sports venue in London, situated between Wood Green and Muswell Hill in the London Borough of Haringey. It is built on the site of Tottenham Wood and the later Tottenham Wood Farm. Originally built by John Johnson and Alfred Meeson, it opened in 1873 but following a fire two weeks after its opening, was rebuilt by Johnson. Intended as "The People's Palace" and often referred to as "Ally Pally", its purpose was to serve as a public centre of recreation, education and entertainment; North London's counterpart to the Crystal Palace in South London. At first a private venture, in 1900, the owners planned to sell it and Alexandra Park for development. A group of neighbouring local authorities managed to acquire it. An Act of Parliament created the Alexandra Palace and Park Trust. The Act required the trustees to maintain the building and park and make them available for the free use and recreation of the public forever. Th ...

The World's First Regular High Definition Television Service Was Inaugurated Here By The BBC 2 November 1936
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

Video Camera Tube
Video camera tubes were devices based on the cathode ray tube that were used in television cameras to capture television images, prior to the introduction of charge-coupled device (CCD) image sensors in the 1980s. Several different types of tubes were in use from the early 1930s, and as late as the 1990s. In these tubes, an electron beam was scanned across an image of the scene to be broadcast focused on a target. This generated a current that was dependent on the brightness of the image on the target at the scan point. The size of the striking ray was tiny compared to the size of the target, allowing 483 horizontal scan lines per image in the NTSC format, 576 lines in PAL, and as many as 1035 lines in Hi-Vision. Cathode ray tube Any vacuum tube which operates using a focused beam of electrons, originally called cathode rays, is known as a cathode ray tube (CRT). These are usually seen as display devices as used in older (i.e., non-flat panel) television receivers and computer d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central Research Laboratories
The Central Research Laboratories, often referred to as CRL, was a British research laboratory that originally belonged to the EMI Corporation. History During the period of 1927–29 EMI invested in developing a research and innovation centre that arguably set the tone for many of the technological advancements that would occur over the next 80 years in the UK and was held in extremely high regard globally. After years operating in central London and across various greater London locations, a new company site was built in the 1980s in Hayes, Middlesex.
