Question: When did Baird cease showing its programs on Henry Swanzy's place of employment?

full_context: Document 1: BBC Television: After a series of test transmissions and special broadcasts that began in August 1936, the BBC Television Service officially launched on 2 November 1936 from a converted wing of Alexandra Palace in London. ``Ally Pally ''housed two studios, various scenery stores, make - up areas, dressing rooms, offices, and the transmitter itself, which then broadcast on the VHF band. BBC television initially used two systems on alternate weeks: the 240 - line Baird intermediate film system and the 405 - line Marconi - EMI system. The use of both formats made the BBC's service the world's first regular high - definition television service; it broadcast from Monday to Saturday between 15: 00 and 16: 00, and 21: 00 and 22: 00. The first programme broadcast -- and thus the first ever, on a dedicated TV channel -- was`` Opening of the BBC Television Service'' at 15: 00. The first major outside broadcast was the coronation of King George VI and Queen Elizabeth in May 1937.
Document 2: BBC Television: The two systems were to run on a trial basis for six months; early television sets supported both resolutions. However, the Baird system, which used a mechanical camera for filmed programming and Farnsworth image dissector cameras for live programming, proved too cumbersome and visually inferior, and ended with closedown (at 22:00) on Saturday 13 February 1937.
Document 3: BBC Television: Mechanically scanned, 30-line television broadcasts by John Logie Baird began in 1929, using the BBC transmitter in London, and by 1930 a regular schedule of programmes was transmitted from the BBC antenna in Brookmans Park. Television production was switched from Baird's company to what is now known as BBC One on 2 August 1932, and continued until September 1935. Regularly scheduled electronically scanned television began from Alexandra Palace in London on 2 November 1936, to just a few hundred viewers in the immediate area. The first programme broadcast – and thus the first ever, on a dedicated TV channel – was "Opening of the BBC Television Service" at 15:00. The first major outside broadcast was the coronation of King George VI and Queen Elizabeth in May 1937. The service was reaching an estimated 25,000–40,000 homes before the outbreak of World War II which caused the service to be suspended in September 1939. The VHF broadcasts would have provided an ideal radio beacon for German bombers homing in on London, and the engineers and technicians of the service would be needed for the war effort, in particular the radar programme.
Document 4: Television in Australia: The first television broadcast in Australia took place on 30 September 1929 at the Menzies Hotel in Melbourne, using the electro - mechanical Radiovision system. Other transmissions took place in the city over the next few weeks. Also in 1929, the Baird system was used on 3DB, 3UZ and 2UE.
Document 5: Henry Swanzy: Henry Swanzy (14 June 1915 – 19 March 2004) was an Anglo-Irish radio producer in Britain's BBC General Overseas Service who is best known for his role in promoting West Indian literature particularly through the programme "Caribbean Voices", where in 1946 he took over from Una Marson, the programme's first producer. Swanzy introduced unpublished writers and continued the magazine programme "with energy, critical insight and generosity". It is widely acknowledged that "his influence on the development of Caribbean literature has been tremendous".
Document 6: BBC Television: The BBC began its own regular television programming from the basement of Broadcasting House, London, on 22 August 1932. The studio moved to larger quarters in 16 Portland Place, London, in February 1934, and continued broadcasting the 30-line images, carried by telephone line to the medium wave transmitter at Brookmans Park, until 11 September 1935, by which time advances in all-electronic television systems made the electromechanical broadcasts obsolete.
Document 7: John Logie Baird: John Logie Baird FRSE (/ ˈloʊɡi bɛərd /; 14 August 1888 -- 14 June 1946) was a Scottish engineer, innovator, one of the inventors of the mechanical television, demonstrating the first working television system on 26 January 1926, and inventor of both the first publicly demonstrated colour television system, and the first purely electronic colour television picture tube.

Document 9: Beyond a Boundary: James initially had difficulty finding a publisher, according to his widow Selma James, but on its publication by Hutchinson "Beyond a Boundary" was well received, and John Arlott wrote in "Wisden":"1963 has been marked by the publication of a cricket book so outstanding as to compel any reviewer to check his adjectives several times before he describes it and, since he is likely to be dealing in superlatives, to measure them carefully to avoid over-praise – which this book does not need … in the opinion of the reviewer, it is the finest book written about the game of cricket."
Document 10: Leon Belleth: Leon Belleth was a popular announcer with Radio Ceylon and subsequently the Sri Lanka Broadcasting Corporation. He presented a range of radio programs including Holiday Choice. Listeners enjoyed his free and easy style of broadcasting.

Document 12: Kerry Juby: Kerry Juby (3 January 1948 – July 2003) was born in Bexley, South London and was a radio DJ who worked for Pirate Radio Station Radio Caroline in the 1960s (initially as an engineer) under the name Kerry Clarke. When London's Capital Radio started in 1973 he was presenter/producer of "Kerry-Go-Round", aimed at younger listeners. He then dedicated more time to producing two weekend magazine shows in "Hullabaloo" and "Sunday Supplement" for the station in addition to working on other outside projects such as the Stage Broadcast Company, which provided the Capital Radio Video Show throughout the 80s and Voicebox Sound Equipment.
Document 13: BBC Television: Baird Television Ltd. made Britain's first television broadcast, on 30 September 1929 from its studio in Long Acre, London, via the BBC's London transmitter, using the electromechanical system pioneered by John Logie Baird. This system used a vertically-scanned image of 30 lines – just enough resolution for a close-up of one person, and with a bandwidth low enough to use existing radio transmitters. Simultaneous transmission of sound and picture was achieved on 30 March 1930, by using the BBC's new twin transmitter at Brookmans Park. By late 1930, 30 minutes of morning programmes were broadcast Monday to Friday, and 30 minutes at midnight on Tuesdays and Fridays, after BBC radio went off the air. Baird broadcasts via the BBC continued until June 1932.
Document 14: Bermuda: The PLP, the party in government when the decision to join CARICOM was made, has been dominated for decades by West Indians and their descendants. (The prominent roles of West Indians among Bermuda's black politicians and labour activists predated party politics in Bermuda, as exemplified by Dr. E. F. Gordon). The late PLP leader, Dame Lois Browne-Evans, and her Trinidadian-born husband, John Evans (who co-founded the West Indian Association of Bermuda in 1976), were prominent members of this group. They have emphasised Bermuda's cultural connections with the West Indies. Many Bermudians, both black and white, who lack family connections to the West Indies have objected to this emphasis.
Document 15: BBC Television: After a series of test transmissions and special broadcasts that began in August, regular BBC television broadcasts officially resumed on 1 October 1936, from a converted wing of Alexandra Palace in London, which housed two studios, various scenery stores, make-up areas, dressing rooms, offices, and the transmitter itself, now broadcasting on the VHF band. BBC television initially used two systems, on alternate weeks: the 240-line Baird intermediate film system and the 405-line Marconi-EMI system, each making the BBC the world's first regular high-definition television service, broadcasting Monday to Saturday from 15:00 to 16:00 and 21:00 to 22:00.
