[lower-alpha 2]

Contents

Early life and education

David Pentecost was born in London. He was educated privately in piano playing for seven years, from age 6, and on the violin for two years from age 9. He attended Christ's College, Finchley [1] (a grammar school in north London), until age 18, and then studied mathematics at Brunel College of Technology. Pentecost passed three examinations at the London College of Music, up to Intermediate level. He then taught himself a large repertoire of classical piano music, during subsequent years.

Significant information technology projects

Elliott Brothers (London) Ltd

1960 – 1962 Pentecost worked as a computer programmer [lower-alpha 3] at computer manufacturer Elliott Brothers in Borehamwood, Hertfordshire – the first British company to become seriously involved with digital computer technology. [2] Pentecost wrote software on the Elliott 405 computer to measure the precise execution time taken by another computer program running simultaneously on the same computer. [3] This software was used to demonstrate that Elliott's employee Tony Hoare’s new sorting techniques method Quicksort was faster than previous sorting techniques. [4] [lower-alpha 4] The Quicksort method, or a version of it, now forms the basis of most computer sorting programs. [5] [6]

Mills Associates Ltd

In 1962, Pentecost moved to Mills Associates Ltd, [lower-alpha 5] where he headed a small team of programmers to implement a unit trust administration system, believed to be the first of its kind. [7] [lower-alpha 6]

Unit Trust Services Ltd

In 1967, Pentecost joined Unit Trust Services Ltd in the City of London, and in 1972 he was appointed as a director. [lower-alpha 7] He designed and implemented what was thought to be the first fully computerised unit trust contract note production system. He chose Honeywell’s new H316 industrial process control mini-computer, having persuaded Honeywell that it would be the first of its type to be used for commercial applications in the UK. [8] [lower-alpha 8] [9] [lower-alpha 9]

Coward Chance (later Clifford Chance)

In 1980, Pentecost joined Coward Chance as Business Systems Manager. In 1985 Pentecost designed and implemented a system on a large Burroughs Corporation mainframe computer, to revolutionise the administrative aspects of the office, replacing typewriters with word processors, all linked to the central computer, for accounting, billing and other purposes. The system was called the Office Automation System, and it incorporated an internal electronic mail system, before electronic mail over the Internet became widely available to the general public. [lower-alpha 10]

Computer industry history research

In 2003, Pentecost learned that Simon Lavington, Emeritus Professor of Computer Science at the University of Essex, was leading a project called Our Computer Heritage, to document the history of British computers for the Computer Conservation Society, whilst pioneers with the knowledge of these computers were still alive. The results of the project are now recorded on the website of the Computer Conservation Society. [10] Pentecost offered, and was asked [lower-alpha 2] to lead part of the project, as co-ordinator for the Elliott 400 series of computers section of the website, and from 2003 to 2011 he collected information about the hardware, software and systems relating to these computers. One of his tasks was to find out about the Elliott 403 computer, which was also known as WREDAC. Only one had been built, in 1955, for the Government's Weapons Research Establishment, [11] in Salisbury, South Australia, for the analysis of guided missile trials at Woomera. [12] Simon Lavington referred to Pentecost's research on the 403 computer in two of his works. [13] [14]

Pentecost wrote an autobiography about his work in the computer industry, and included details of his research for the Computer Conservation Society's project to document early British computers. The Society regards his autobiography as a unique book, describing the complete working life experiences of a 20th-century computer programmer. [15] The Archives of IT website also regards his autobiography worthy of inclusion in the Reminiscences section of its website [16]

Music career

In 1987 Pentecost took organ lessons from Catherine Ennis, at St Lawrence Jewry church, which led to his becoming, for a few years, one of the organists at St. Barnabas’ Church, in Linslade, Bedfordshire.

In 2001, he was accepted as a member of the Chopin Society in London. [17] [lower-alpha 11] From 2002 to 2005, before emigrating to Cyprus, he played at five of the Society's Members’ Matinée concerts, and included in his programmes a few of his early piano compositions; in 2023 he played some of his latest compositions at a sixth such concert. [18] [lower-alpha 12]

From 2007 to 2011, after emigrating to Cyprus, Pentecost formed and organised two groups of amateur pianists in Cyprus, one in Paphos, the other in Limassol. They were called Pianists’ Circles and were based on similar principles to those of the Chopin Society's Members’ Matinée concerts. [19] [lower-alpha 13]

He began teaching himself to compose piano solo music in 1996, and he has continued this activity since then, as a professional composer. Russian pianist Tatiana Stupak played his Nocturne Op.18 at the Technopolis Cultural Centre in Paphos on 8 December 2017. [20] He helped Tatiana Stupak with the administration of her concerts in Cyprus after she turned professional. [21] Tatiana Stupak and another Russian pianist, Natalia Lezedova, played about twenty of his early piano works in Cyprus at a public concert in Paphos on 13 February 2018. [22] Tatiana Stupak played one of his compositions at a concert on 12 June 2019 at the Cyprus’ Presidential Palace. [23] Eight of his compositions were performed at a concert held on 12 May 2021 at the Rialto Theatre, Limassol. [24] Eight of his compositions were performed at a concert at the Historical Museum of Serbia in Belgrade on 21 April 2022, by pianist Tatiana Stupak and violinist Olivera Rialas. [25] His Opus 56, Poème, for violin and piano, was played at a concert ‘Music through the Ages’ at Kolossi Castle, in Cyprus, on 10 June 2022. [26] The Polish pianist Wojciech Waleczek  [ pl ] played Pentecost’s Reverie, Op.6 at a Polish Independence Day recital in Larnaca, Cyprus, on 5 November 2022. [27] [28]

The Cyprus national broadcaster, Cyprus Broadcasting Corporation classical music radio station RIK 4 Classic, has played some of Tatiana Stupak's recordings of his compositions.

In 2015, Pentecost researched the life of the once world-famous Scottish pianist Frederic Lamond (pianist), who was a pupil [29] of Franz Liszt, shortly before Liszt's death in 1886. As a result, he made a documentary video, [30] intended for students of music history, about Lamond and his time spent with Liszt.

In 2018, Pentecost won first prize for composition at the 4th International Competition of Musicians in Cyprus. [31] [lower-alpha 14]

Up to July 2024, he wrote 73 piano solo works, two for church organ, and two works for violin and piano. A CD of seventeen of his compositions was issued in 2021, by stupakrecords.com, 16 played by Tatiana Stupak, one played by himself, all of which he recorded and mastered. [32] His music was generally not written in modern styles. His music is not atonal or minimalist. [33] According to the sheet music published at sheetmusicplus.com, most of his works are in 19th century romantic styles, although a few works are in classical and baroque styles. [34] In July 2023, he published the 4th edition of his 'My Life in Music' - see Bibliography section below, and Notes k to n.
