Restoring or Rebuilding an Altered Skinner Organ

The first question is which firm built the instrument, under which opus number and in which year, and the answer can be layered rather than single. As of September 1, 2026, one rebuilding firm publishes its work at St. Paul’s R. C. Church in Princeton, New Jersey under its own Opus 38, while describing the instrument as originally built by Ernest M. Skinner as Opus 537 in 1925 for the Peabody Conservatory of Music in Baltimore, so that one organ carries a builder’s opus number, a rebuilder’s opus number and a location history that begins in another city. What a company name or an opus number does and does not establish, and which of the several Skinner-family firms was trading on a given date, is worked through at Skinner and Aeolian-Skinner Identity, Company Eras, and Opus Numbers; where the factory records that fix a contract are held is at Finding Skinner and Aeolian-Skinner Factory Records.

The second question is what has been done to the instrument since it was built, by whom and when, and the honest answer is often more than one campaign. The same Princeton firm states that Opus 537 had already been modified in the 1940s and again in the 1950s by the Aeolian-Skinner Organ Company before its later rebuilding, so that the current work is at least the third layer on a 1925 instrument. Every layer has to be named with the firm that made it, because the firms are distinct: the Aeolian-Skinner Organ Company that revised Opus 537 in the 1940s is not the firm that built it. Why so many of these instruments were altered in the middle of the twentieth century, and what those alterations typically changed, is its own history at Why Skinner Organs Were Altered During the Mid-Twentieth Century.

The third question is whether earlier material of historic value survives inside the instrument as it now stands, and the answer may be partial. The re-creation account of Opus 751 of the Skinner Organ Company, built in 1929 with 36 ranks, reports that a 1965 rebuild left only twelve of the original ranks intact, reduced the Great to 32 notes to form a new Pedal division, repitched or converted twelve ranks, replaced the original Harmonic Mixture with a one-foot Scharff on six-inch wind, discarded stops including the Cello and Waldhorn, and enlarged the instrument to 64 ranks, eighteen of them mixtures. The University of Chicago’s Rockefeller Memorial Chapel, by contrast, held stored original pipework from Opus 634 that a later restoration returned to use. Which surviving pipework is significant, and what in it can and cannot be undone, is the question owned by Preserving Historic Skinner Pipework.

On an instrument with several campaigns behind it, the state a restoration would conserve may be a later state rather than any original. As of August 31, 2026, St. Bartholomew’s Church in New York records four successive campaigns on its organ: Ernest M. Skinner in 1918, Aeolian-Skinner under G. Donald Harrison in 1937, a further chancel revision in 1953, and Donald Gillett’s 1970-71 rebuild with new chests, structure and many new pipes. The church states that the instrument has been tonally unchanged since 1971, so the state now conserved there is the 1971 state. An owner asking to restore such an instrument has first to say which of its states is meant, and the answer is a documented finding about that instrument rather than a preference.

An instrument that survives unaltered did not necessarily survive by decision. Historic Trinity Lutheran Church in Detroit records that its Skinner Organ Company Opus 808 of 1931 remained unaltered for decades because of financial constraints during the Organ Reform Movement era, so that its intactness resulted from lack of funds rather than from an early conservation choice.

The Yale Institute of Sacred Music states that, unlike three comparable university organs of the same era that were substantially altered, the Newberry Memorial Organ in Woolsey Hall remained exactly as it was finished, as much for a lack of funds to alter it as for its outstanding musical qualities, and The Diapason states of the same instrument that there have been no tonal or mechanical changes whatsoever apart from furnishing compression springs and dowel-nutting. Original condition there means the instrument as it was finished in 1929, on an organ that had earlier work by Hutchings-Votey in 1903 and J. W. Steere and Sons in 1915, which is one more reason the question of which state is being conserved is asked instrument by instrument.

Where a documented campaign removed a division or a set of stops, a later project may return it, and the record of who removed what and when is what makes that possible. Andover Organ Company’s work history for the organ at Methuen Memorial Music Hall records that the Great reeds had been removed by Harrison in Aeolian-Skinner’s 1947 rebuild of the instrument, and that Andover restored those divisions in 1970 and 2007. A work history of that quality is uncommon, and it concerns one instrument; the 1947 work was Aeolian-Skinner’s, a different firm from the Skinner Organ Company, and the two are not to be run together.

No condition survey, aggregate condition grading or originality census exists for Skinner Organ Company, Aeolian-Skinner or Ernest M. Skinner & Son instruments in any source located as of September 1, 2026, and the absence of one in the published record is not proof that no such survey exists anywhere. The OHS Pipe Organ Database carries an extant flag but no condition field on its public pages, and the Aeolian-Skinner Archives website itself says that notes on current condition and alterations are found in the published opus list rather than online. It follows that any statement about how commonly these instruments survive unaltered is unsupported, that the representativeness of published restoration cases cannot be established, and that findings drawn from those cases remain specific to the instruments they describe.

Published restoration accounts concentrate on large, prominent and comparatively well-funded instruments, so the cases that can be cited are not a sample of the instruments most owners have. The Diapason’s signature-organ articles, for instance, discuss cathedral, university, concert-hall and museum organs, and no located source quantifies how such instruments compare with the ordinary two- and three-manual church organs. The archived opus lists themselves show that the great majority of the contracts they record were for two- and three-manual instruments rather than the four- and five-manual organs that dominate the restoration literature, an observation of the lists as they stand rather than a tabulated statistic.

Some documented projects are reported in terms of the mechanism alone. The Diapason reports that the 1990-1998 restoration of Opus 327, a Skinner Organ Company instrument contracted in 1921, releathered all 3,800 of the instrument’s leather pouches along with the reservoirs and completely reconstructed the console electro-pneumatic action. Létourneau reported that the 2007-2009 restoration of Aeolian-Skinner Opus 1257 of 1955 releathered the wind reservoirs, concussion bellows, expression motors, pouchboards, note and stop primaries, and tremolo units. Work of this kind can also be spread over years: the institutional record for Skinner Organ Company Opus 769 of 1929 documents console releathering in 2004, chest releathering in 2007, blower and motor restoration in 2011 after flooding, rewiring in 2014, and reed restoration in 2019-2020. What these components are and how their leather and linkages fail is explained at Skinner Pitman and Offset Chests, Leather, and Failure Modes, Skinner Whiffletree Swell Engines and Skinner Console, Relay, Combination Action, and Later Retrofits.

Other documented projects combined restoration of original material with replicas of what was lost and with additions. The University of Chicago’s Rockefeller Memorial Chapel records that Schantz Organ Company restored Opus 634 in 2005-2006, restoring stored original pipework and building replicas for lost or damaged ranks, completely rebuilding the chancel console inside its original Goodhue-designed case, adding a new two-manual gallery console, restoring all original chancel windchests and reservoirs, and adding twenty-two new ranks to reach 132 ranks and 8,565 pipes.

The Cleveland Orchestra’s archives record that the 1930 Norton Memorial Organ at Severance Hall, of 94 ranks and 6,025 pipes, was housed at the Schantz Company from 1997 to 2000 with all pipes and machinery removed and reinstalled and new facade pipes built, and was reinstalled behind the stage in 2000 with a rededication in January 2001. When replication is the documented answer, and what a faithful replica of a lost rank needs, is owned by Preserving Historic Skinner Pipework.

Other documented projects changed the instrument rather than returning it to a prior state, and their owners and contractors describe them in those terms. As of September 1, 2026, the Princeton firm states that in its rebuild it retained and rebuilt all of what it calls the E.M. Skinner and Aeolian-Skinner offset chests and regulators, and cleaned and repaired all sixty-four ranks of pipes, in an instrument it publishes under its own opus number. A documented project at Druid Hills Presbyterian Church in Atlanta, Georgia restored a G. Donald Harrison-era Aeolian-Skinner organ ‘with additions as originally planned,’ completing tonal expansions the original design had called for but had not fully implemented; the firm’s summary gives no rank counts or dates.

As of August 31, 2026, the Washington National Cathedral instrument, built as Ernest M. Skinner & Son Opus 510 in 1938 and enlarged and revised by Aeolian-Skinner in 1975 to 121 stops, 189 ranks and 10,647 pipes, is the subject of a removal and rebuilding project announced for 2024 to 2028 and described as using portions of the previous instrument where possible and appropriate. The 1965 enlargement of Opus 751 to 64 ranks, described above, was itself a rebuild of this kind, and the later re-creation of that instrument is reported to have built new chests in the Skinner style.

The words restoration, renovation and rebuild do not tell you what a proposal contains, because none of them has an agreed professional definition and they are not standardized against one another. Washington National Cathedral describes the work on what it calls its 1938 Ernest M. Skinner organ as a complete overhaul and renovation, its announcement of the project used the word renovate, and its project page refers to Foley-Baker conducting the restoration work, so that three scope words are applied to one project by its own owner.

The definitions section of the Organ Historical Society’s 2008 Guidelines for Conservation and Restoration does not define rebuild, rebuilding or renovation, so rebuilding and renovation take their meaning from the contract rather than from a professional consensus, and the International Society of Organbuilders describes its journal as covering instruments built, re-built or restored, with neither conservation nor renovation as a category.

The definitions that do exist are individual ones, and they disagree. John Bishop, writing in The Diapason in 2009, characterizes ‘rebuild’ as a deliberately vague word amounting to a philosophical free-for-all, in which the builder is not necessarily making an artistic statement and the focus is narrowly technical, and proposes ‘renovation’ as the preferred term for work that focuses on the original builder’s intentions while permitting the addition of ranks and other modifications. Buzard Pipe Organ Builders, as of September 1, 2026, separates restoration undertaken in accordance with Organ Historical Society guidelines from rebuilding and tonal enhancements and from re-leathering and action renovation, treating action renovation as a service alongside re-leathering rather than as Bishop’s ethical category.

Foley-Baker, Inc. lists seven service categories, from reconditioning and rebuilding to console reconditioning and relay systems, in which neither restoration nor conservation appears by name, and Andover Organ Company describes rebuilding as work to help an existing instrument achieve its full mechanical and musical potential, which may include judicious tonal changes or additions, while presenting restoration of historic instruments as a separate service. Each of these is that firm’s own usage; none is an industry standard, no professional body located has settled the question, and the dispute over what the words mean remains open.

Compare proposals on what each retains, replaces, adds and documents, and read the guidance on whether a significant instrument may be rebuilt at all as a dispute between named bodies rather than a settled rule. The Organ Historical Society’s 2008 guidelines state that interventions should not modify the known aesthetic and physical characteristics of an organ, especially by removing or obscuring historic material or through non-essential re-voicing, that enlargements or modernizations should be strongly avoided whenever possible, and that where removal of historic material is unavoidable the affected components must first be documented in their pre-restoration state; the word is avoided, not prohibited, and the guidelines are advisory.

Church of England guidance states that if an organ is of historical value or is fundamentally sound the best advice is to restore it, a Diocese of Exeter advisory note of 2016 contemplates replacement where the existing organ is in a poor state, and neither sets out criteria for identifying a poor candidate for restoration. The 1998 New South Wales Heritage and Organ Historical Trust of Australia guide states that a significant organ should not be altered through enlargement or rebuilding, conditioned on the organ first having been assessed as significant, and the British Institute of Organ Studies warns that alterations made to keep pace with changes in fashion weaken the builder’s original concept.

Other named parties argue for intervention on stated grounds. The American Institute of Organbuilders’ Guidelines for Fine Organbuilding, a 1994 text reprinted in 2020, state that retaining electrical equipment not meeting current code standards is not recommended for reasons of reliability, safety and potential product liability, a criterion that can force a control-system replacement irrespective of historic value. What such a replacement displaces on a Skinner-family console, and what can be kept alongside it, is explained at Skinner Console, Relay, Combination Action, and Later Retrofits. The American Theatre Organ Society’s 1992 guidelines treat modern modifications such as solid-state relay systems and combination actions as permissible where necessary for contemporary function, a position written for theatre organs, where console mobility is a performance requirement that a fixed church instrument does not share.

Andover Organ Company states that a rebuild can produce the functional equivalent of a new instrument for far less cost, a company statement with an evident commercial interest and no cost data behind it. Washington National Cathedral states that the aim of its project is to make the instrument one cohesive system while retaining the best parts of Ernest M. Skinner’s original design, a selection judgment its own pages assert rather than document, and John Bishop frames the governing tension as retaining an organ’s musical and artistic qualities while keeping the balance between artistry and expense in view.

At the far end of the conservation side, Watson and Barclay state in a 2014 reference entry that some instruments serve history better by remaining unplayable so as to preserve construction evidence, the position most contested by performing musicians. These positions differ in authority, scope and date, and whether a significant instrument may be rebuilt remains disputed among them.

Two further things a proposal can be read for are the firm’s stated posture toward another builder’s voice and where its replacement parts will come from. Schantz Organ Company states, as of September 2, 2026, that ‘leaving our thumbprint or tonal signature is not the goal of the successful restorer’ and describes its approach as recapitulating the voice of the original builder; that is a stated philosophy, not a demonstrated outcome. In documented projects, replacement components for these instruments have come either from the general organ-supply trade or from fabrication to pattern: Reisner electro-magnets were installed during the Opus 1257 restoration, new pitman valves were fabricated for Opus 459, and new chests were built in the Skinner style for the Opus 751 re-creation.

Deferral has a documented price in particular instruments, though no one case predicts another. The University of Chicago’s Rockefeller Memorial Chapel records that Opus 634 of 1927-28 deteriorated after mid-1970s alterations ‘due to numerous water leaks and lack of sufficient funding to maintain its aging reservoirs and windchests,’ and was taken out of service in 2001 before the 2005-2006 restoration returned its stored original pipework to use.

The Diapason reports that by the late 1980s the leather in Opus 327 had degraded to the point that many stops were completely dead or had so many dead notes as to be unusable, that the combination action had become increasingly unreliable, and that some stops had been silent for two or three decades; by the time the 1990-1998 restoration began, the work reached every one of the instrument’s 3,800 pouches. Létourneau reported that at Aeolian-Skinner Opus 1257 one of the pneumatic swell engines had failed entirely before restoration. What fails in the leather, the expression engines and the console, and why, belongs to Skinner Pitman and Offset Chests, Leather, and Failure Modes, Skinner Whiffletree Swell Engines and Skinner Console, Relay, Combination Action, and Later Retrofits; what matters here is that each of these conditions was already part of the scope by the time a decision was made.

Modification layered on modification is what one owner describes as turning its instrument into one beyond repair. As of September 1, 2026, Washington National Cathedral states that about one-third of what it calls its 1938 Ernest M. Skinner organ no longer functions because of hodgepodge layers of modifications and fixes accumulated over decades, that the instrument is beyond repair, and that it requires a complete overhaul and renovation. That is an owner’s statement about one organ, and it sets no general threshold at which repair ceases to be viable. Each earlier layer, such as the 1965 rebuild that left twelve of Opus 751’s 36 original ranks intact, is also material that any later decision has to account for, whether the aim is to keep it, return through it or build past it.

A defensible scope rests on an inspection that records what the instrument now is, layer by layer, before anyone chooses a word for the work. The Organ Historical Society’s 2008 guidelines make the point from the other direction: where removal of historic material is unavoidable, the affected components are to be documented in their pre-restoration state first, so the record of the instrument before work is part of the work itself. The three questions at the head of this page, answered from the records and from the instrument, are what such an inspection has to settle, and where the answer is a later state rather than an original, the proposal has to say which state it is conserving.

Craftsman Pipe Organs accepts work only after appropriate technical and logistical review, and scope, price, schedule, visit count, deposits, payment terms, warranties and response commitments are project-specific and controlled by the accepted written proposal or agreement: no universal warranty, no universal emergency-response promise, no fixed visit count and no guaranteed completion schedule. When a project requires additional domain expertise, outside specialists or manufacturers may be involved and their roles are disclosed. That describes how a project is taken on once the evidence above exists; it does not describe what any particular instrument needs.
