John Compton Organs: Pipe, Theatre, Melotone, and Electrone Boundaries

Compton made pipe organs, one electronic attachment and two complete electronic instruments, and the four must never be described by one word. The pipe organs went to both churches and cinemas. The Melotone was an electronic attachment: it added a solo voice to a cinema pipe organ that already existed and played through that organ’s own relay. The Theatrone was a complete electronic instrument for cinemas, and the Electrone was the equivalent complete electronic instrument for churches; neither contained pipes.

A private enthusiast site also records the model names Miniatura, Augmentum and Series 4, but which family each name belongs to is not established by that site, so a model name on a listing is a lead rather than a classification. A church setting does not by itself mean an Electrone either: church pipe organs, including Downside Abbey in 1931, ran alongside the cinema work throughout the firm’s cinema-organ period.

The family decides which record source can hold the object at all. The National Pipe Organ Register aims to list every organ in the country and organizes its data as dated surveys of organs in buildings, so its scope covers a Compton church or cinema pipe organ; it is not a builder census of any product. The listings that do collect Compton instruments by name, including the electronic ones, are private compilations: one gives particular attention to post-war Electrone instruments, another sorts its entries by product line, and neither states a method or a coverage. A pipe organ therefore has an institutional record to look for; an Electrone has only private leads.

Accounts of how the firm began do not agree, and the disagreement changes who is credited with the design behind it. A general reference account records that John Compton set up Musson & Compton in Nottingham in 1902 with James Frederick Musson and that the partnership dissolved in 1904; a commercial history dates the founding of “the Compton Organ Company LTD” to 1904, when Musson departed, so the two describe the same transition differently. The same general reference account has Albert Henry Midgley appointed technical director of the John Compton Organ Company in 1925.

Grace’s Guide to British Industrial History instead gives the founders of the John Compton Organ Co as “Albert Henry Midgley, John Compton, and Reginald and Pickering Walker”, formed as a partnership “to develop Midgley’s organ design”, and cites no partnership deed or company registration for it. Whether these accounts describe one founding or two sequential legal entities is not settled, and no other account found places Midgley or the Walkers at the founding. Before any of this, two independent accounts agree that Compton apprenticed at Brindley and Foster, organ builders of Sheffield, from 1898, one adding that he then trained under Charles Lloyd.

The works moved twice, and the trade directories record a late change in what the factory made. The general reference account puts the move to workshops at Turnham Green Terrace in Chiswick, vacated by August Gern, in 1919, and the move to a new factory at Chase Road in Park Royal, North Acton, in 1930. Grace’s Guide, citing the 1947 British Industries Fair catalog and the 1954 Aeroplane Directory, records a dual address of Chase Estate, Willesden and Minerva Road, North Acton, London NW10; church instruments including Downside Abbey in 1931; a 1947 fair entry showing “Compton Electrone (Pipeless Organ)”, Miniatura and pipe organs “for various institutions” alongside electric space heaters; and a 1954 entry describing production as “Components, woodwork and metal work assemblies”.

That 1954 wording points to a shift away from complete instruments in the years before the firm lost its founder in 1957, though it fixes no discontinuation date for any product, and the absence of the Theatrone from the 1947 entry may reflect the format of that catalog rather than the end of the product. Grace’s Guide also states that the firm ceased trading in 1970, one of four different closing dates set out below. No count of the church organs has been found; the 261 figure in the next Block covers theatre organs only.

Three independent accounts agree that the John Compton Organ Company built 261 theatre organs installed in cinemas and theatres in the British Isles, and one adds that the final instrument opened on 2 September 1939 at the Plaza Cinema, Crosby. The figure may derive from a single underlying compilation, and it counts theatre organs only; church organs and electronic instruments sit outside it.

Named installations from an enthusiast account give a sense of the range: a four-manual instrument at the Shepherds Bush Pavilion in 1923, later enlarged to 19 ranks and carrying the “Gaumont Style” console, and the only five-manual Compton theatre organ, at the Odeon Leicester Square. The same account’s claim that Compton created “the world’s first Photoplayer” at the Palace Cinema, Tamworth in 1909 is that account’s alone, and it concerns a different machine in a different country from the American Fotoplayer of 1912, so the two should not be merged.

Compton’s use of the extension principle is supportable; priority for it is not. A commercial history states that the firm “pioneered the extension principle of organ design”, which “completely enclosed all pipework whilst also utilising an electric keyboard action” to produce compact instruments for worship spaces and entertainment venues. What that supports is that Compton applied extension with fully enclosed pipework and electric key action; the same literature attributes the extension principle to Hope-Jones, so “pioneered” overstates priority.

A claim that a firm originated a mechanism is also not evidence that a patent for it exists or has been found. No located patent covers the extension principle, double-touch cancelling or luminous stop control, and the general reference account that credits the firm with “many original patents” supplies no numbers; the patents that can be cited by number are set out in Block E. For the Hope-Jones side of the extension attribution, see Robert Hope-Jones: Firms, Patents, and the Wurlitzer Boundary.

A Melotone is an electronic attachment to a pipe organ that already exists; a Theatrone or an Electrone is a complete electronic instrument with no pipes, and a listing that uses one word for both has misdescribed one of them. The Theatre Organs of Great Britain reference project records the Melotone as fitted to some Compton organs from 1935 to 1939, with 74 installations documented, delivering a modified sine-wave tone generated by rotating discs through the host pipe organ’s conventional relay at 8′, 4′, 2⅔’ and 2′ pitches, with derived Krummhorn, Musette and Carillon mixtures plus vibrato and echo. Routing through the host organ’s relay is what makes it an attachment rather than an instrument.

Its date and scale differ by account. An enthusiast history dates it to 1932, credits technician Leslie Bourn with developing it, describes its audio as generated from engraved conductive plates, and states it was “Incorporated into 74 organs (1935-1939)” offering “a novel and ethereal voice, unashamedly synthetic in character”; Grace’s Guide dates the Melotone attachment to 1935; a commercial history dates Bourn’s electrostatic tone-generation patent filing to 1932. The 74 figure rests on one reference project. The Theatrone, the cinema model, and the Electrone, the church model, were complete electronic instruments of the late 1930s, and the 1947 fair entry called the Electrone a “Pipeless Organ”.

The Electrone generated its tones electrostatically from motor-driven disks, not from pipes. John Harvey, writing in the Darlington and District Organ and Choirmasters Association Magazine in January 2010, describes it: “The sound was produced by the rotation of a disk with a number of etched waveforms in close proximity to a stationary plate; the variation of capacitance as the disk rotates generating the wave which is fed into an amplifier”. There were twelve tone generators, “one for each semitone, and spun with a motor, the pitch for each semitone being determined by the diameter of the pulley wheel”, each producing only seven waveforms, so the whole instrument had “just 84 tones”.

Harvey records the launch of the Electrone in 1938 on technology Leslie Bourn had developed in the 1920s, a post-war resumption with “a two-manual church specification with twelve electrostatic disks” refined through the 1950s, and custom three-manual versions for the Royal Festival Hall and BBC Maida Vale Studios; the installation claims are his article’s own. Grace’s Guide separately dates the firm’s electronic tones from 1929. None of this describes a pipe organ, and none of it transfers to one.

Two further Compton names turn up in listings, and each needs its own classification. The Solo Cello of 1933, recorded by an enthusiast history, was an electromagnetic device with “one string that was played (i.e. bowed) by a rotating resin wheel”, fitted to only 20 organs and discontinued in 1935, which that account attributes to unreliability; it is neither a Melotone nor an electronic instrument.

The BBC’s Compton instruments show how one installation can cross the boundary. A general reference account records a 1933 Compton at Broadcasting House with 2,826 pipes in 35 ranks, which proved impractical because of sound leakage, and a four-manual “Compton Melotone and Electrostatic Organ with 23 units” installed at St George’s Hall in 1936, first broadcast on 20 October 1936 and later lost to bomb damage. The 1936 instrument combined pipework with Melotone and electrostatic generation, so it was a hybrid rather than a pipe organ or a complete electronic instrument, and any record of it has to say which part it means.

Three British patents for electric stop actions name the Compton firm, and they are the pipe-organ patents that can be cited by number. GB 378,579, “Improvements in and relating to electric stop actions for organs and the like”, applicant Compton Organ Co., Ltd., names J. Compton of Chase Road, Willesden and J. I. Taylor of Bedford Park as inventor-proprietors, was filed 9 June 1931 and published 18 August 1932, and claims an electric stop action in which any combination of stops can be set by any one of a number of combination switches; it is the document on which John Compton himself is a named inventor.

GB 436,737, under the same title, filed 30 April 1934 and published 17 October 1935, names J. I. Taylor together with Compton Organ Co., Ltd. of Chase Road, North Acton, and describes a combination-capture stop action using a matrix of magnets, one set for the stops and one for the pistons, rather than a memory element for every stop-piston pair. GB 437,742, filed one day later on 1 May 1934 and published 1 November 1935, names J. I. Taylor and A. H. Midgley as inventors and claims an electromagnetic combination system in which a piston moves an apertured control strip and stop-key selector magnets reposition contacts that settle into the apertures to store the combination.

An independent technical-history study had suggested that Midgley “might also have had a hand in designing” GB 436,737, on which he is not named; his inventorship is documented on the face of GB 437,742 only. A patent records a claimed design, not what was built or fitted to any instrument, and a venue’s phrase such as the Stockport Plaza’s “Compton’s patent electrical action” names no patent at all.

The firm’s documented interest in Leslie Bourn’s electrostatic tone generation dates from June 1932, and that date is a legal-title fact rather than evidence about who did the development work. GB 403,444, “Improvements in or relating to electrical musical instruments”, names Compton Organ Co Ltd of Chase Road, Willesden as applicant and L. E. A. Bourn of Ashford, Middlesex as inventor, applied 28 June 1932 and published 28 December 1933.

That same 28 June 1932 date is the Great Britain priority date on Bourn’s United States Patent 1,996,669, “Electrical musical instrument”, filed 24 February 1934 and granted 2 April 1935 with no corporate assignee on its face and reissued as USRE 19,702 on 17 September 1935; it describes coaxial undulating rings scanned by a rotating electrode. Bourn’s follow-on United States Patent 2,032,044, filed 31 January 1935 and granted 25 February 1936, is assigned on the patent itself to Compton John Organ Co Ltd. Together these establish one British application and one American patent assignment, not a general licensing or employment relationship between Bourn and the firm.

Set against them, the general reference account’s statement that “The company was awarded many original patents in things ranging from simple organ mechanisms to the most complex, state-of-the-art electronic and electrical inventions” remains an attributed claim without an enumerated list. The five patents naming the firm above are a floor, not a total, and none of them covers the extension principle, double-touch cancelling or luminous stop control.

The firm’s end is dated four different ways, and none of the four can be chosen on the present evidence. Harvey’s 2010 article and a general reference account both state that “The business was wound up around 1965. The pipe organ department was sold to Rushworth and Dreaper and the electronic department became Makin Organs”. An enthusiast history instead gives 1964 for the sale of the pipe organ division to Rushworth and Dreaper Ltd, 1967 for acquisition by Hirel Electronic Developments Ltd, and liquidation in 1971. Grace’s Guide gives 1970 for the cessation of trading. A Companies House record, a gazette notice or a liquidation document would settle the sequence; choosing among the four accounts would not.

Each half of the business went to a different firm, so there is no single successor to the firm. Multiple accounts agree that the pipe-organ department went to Rushworth and Dreaper Ltd while the electronic department became Makin Organs. An enthusiast compilation adds that after the 1971 liquidation the remnants were acquired by J. R. M. Pilling, who formed J. J. Makin Organs Ltd of Rochdale, Lancashire, and that Makin was acquired by the Dutch electronic-organ maker Johannus in 1997; the Pilling name and the 1997 date rest on that one compilation.

The Makin and Johannus line therefore descends from Compton’s electronic department. It is a product-line successor to the Electrone side of the business and nothing wider: it is not a successor to the firm, and it is not a successor to the pipe-organ department, whose transfer went to Rushworth and Dreaper Ltd. A Compton pipe organ has no lineage through Makin or Johannus, and the present corporate status of either firm is a separate, dated question.

For a Compton pipe organ in a British building, the National Pipe Organ Register is the institutional record to consult, and its unit of record is a dated survey of an organ rather than the instrument itself. The British Institute of Organ Studies states that the register “aims to list details of every organ in the country”, that “The NPOR is owned by the British Institute of Organ Studies (BIOS) and its development is guided by members of the Council. The operation of the NPOR is managed by the Royal College of Organists through an agreement with BIOS”, and that it is free of charge with no stated registration requirement.

Each survey shows the building name and address, an NPOR index for the survey, a surveyor code identifying the source of the information, the date of survey, the number of manuals and whether pedals are present, and builders and dates; one building can carry several surveys of different periods or by different surveyors, and the surveyor code is the field that carries the evidential weight of any entry. BIOS adds that “The NPOR is not able to confirm the contents of any particular survey but would be most grateful for information on corrections or omissions.”

What the register holds for Compton, and how many records, has not been checked: no Compton survey has been read and no builder search has been run, so the register’s Compton coverage is unverified until you run that search yourself. The operating agreement between BIOS and the Royal College of Organists is a present-tense arrangement that can change, so read the register’s own description of itself at the time you use it. As of 2 September 2026, older citations that point to NPORView.html or cgi-bin record addresses return only a notice to enable JavaScript, so a record cited that way has to be found again through the register’s search.

The handlist to the British Organ Archive contains no records for the John Compton Organ Company or for Compton organs, although the same handlist holds Hope-Jones material and notes Thomas S. Jones & Son of London advertising in the 1920s as “the largest builders of cinema organs”. That is a record not found in one handlist, not proof that no Compton business records survive. The Cadbury Research Library’s own catalog, Companies House, the Cinema Organ Society’s archive and private holdings are separate routes, and the society’s archive is a member resource with no public catalog.

No institutional, publicly searchable, builder-indexed census of surviving Compton instruments has been found, so the listings that collect Compton instruments by name are private. One is The Compton List, compiled by Ivor Buckingham, which a third-party history describes as the work without which its own Compton coverage could not have been written, with responsibility for the list since attributed by that history to Stephen Dutfield. Its cited web address, on the host zyworld.com, no longer resolves as of 2 September 2026. A dead host is evidence about an address, not about the compilation: nothing supports saying the list has been lost, and nothing supports telling a reader it can be consulted, because no first-party statement, current location, printed edition or archival deposit for it has been found and its present custody, contents, coverage and terms of consultation are undocumented.

Two other private compilations are reachable. A site maintained by Chris Lawton documents roughly 150 installation locations across England, Wales and Scotland with video, gives particular attention to post-war Electrone instruments, and states of itself that it does not provide opus or job numbers or comprehensive technical specifications, so its records cannot be tied to any factory numbering series. An anonymous listing organizes its entries by location and by product line (Miniatura, Augmentum, Series 4, Electrone and cinema organs), keeps a section for installations no longer in existence, carries no compiler name, sources, dates or terms of use, and closes that section with “All information of known Compton installations no longer around would be most appreciated!” Neither is a counted census. The number of surviving Compton instruments, and how many remain in their original buildings, are unestablished; no dated census with a stated method exists.

The register and the private compilations answer different questions and carry different authority. The register records dated surveys of organs in buildings under institutional governance, with a surveyor code behind each entry; a private census lists what one compiler has found, organized by location and visit, without a stated method or coverage. Use the register to document a pipe organ and a private census to find leads, and do not read either as a survivor count.

Only one named Compton instrument carries a dated status statement, and it is a progress note rather than a condition survey. The Cinema Organ Society’s news page carries an item dated 19 August 2025 stating that refurbishment work continues on the Compton organ in Thorngate Hall, Gosport, with an open day, a concert and a silent-film event planned during the work; it says nothing about the instrument’s originality, completeness or playing condition, and any later news item supersedes it.

The Stockport Plaza’s own page describes its 1932 Compton, built for the Plaza with a console designed by Norman Cocker of Manchester Cathedral, three manuals, eleven ranks in two chambers, 798 pipes, about 149 to 150 stop tabs and 42 toe and thumb pistons, and states that it was “the first Compton Theatre Organ to be provided with an illuminated console surround”. The “first” claim is the venue’s, no job or opus number is given, and the page’s statements about the instrument’s condition and about restoration work in progress carry no date, so they cannot stand as a dated status.

Two directory-type sources help find instruments without establishing their status. The Cinema Organ Society maintains a Compton at Fentham Hall, Hampton-in-Arden, originally from the Tower Cinema, West Bromwich, a relocated instrument recorded by its original cinema and its present hall. The American Theatre Organ Society’s United Kingdom listing records a 4/44 Compton at the Civic Hall, Wolverhampton with region, venue, specification and manufacturer, but with no dates, no status field and no link to any British society or register, under a 2024 copyright footer. Whichever family a Compton object belongs to, a dated written record of what is actually present in the building is the starting point for any documentation or project planning.
