Wicks Organs by Tonal and Production Era

The change the profile records is physical, and it runs through the instrument twice. The first boundary is tonal: closed-toe voicing on the earlier, higher pressures gives way to open-toe voicing on two inches of wind or less, with regulators developed to work at those lower pressures. The second is electrical: the same profile lists solid-state switching and combination actions among the introductions of the 1960s and 1970s, placing the factory change over those two decades rather than at a single year. An organ from the heavily romantic decades and one from the neo-Baroque period are therefore different tonal-era instruments, voiced on different wind, even though both carry the same builder’s name.

The switching generations, and what replacing a relay involves, are at Wicks Control-System Generations and Relay Replacement Decisions. The action beneath the pipes is described at Wicks DIRECT-ELECTRIC Action: Meaning, Boundaries, and Comparison.

An era placement does not date an instrument. The profile describes a change made over the course of the 1960s and 1970s, not a year in which one practice replaced the other, so documented differences in wind pressure, voicing and regulator design place an organ in a period of Wicks practice without giving it a build year. The year comes from the opus number, the nameplate and the dated records, read at Identifying and Dating Wicks Organs, Companies, and Opus Suffixes, and from whatever factory paperwork survives, discussed at Wicks Factory Records and Opus Documentation. Whether what is inside the instrument is still original is another question again, taken up at Preserving Versus Replacing Original Wicks Action.

The earlier instruments are the heavily romantic organs of the 1930s and 1940s, as the 2005 profile describes them, voiced closed-toe on the higher pressures the firm later gave up. The company’s own tonal-philosophy page calls its instruments of those decades Willis-influenced and lists ‘the Theater Organs of the same era’ beside them. Tonal responsibility before the change is documented by name for at least one instrument: a listing on the current Wicks website for Opus 3140, a four-manual organ of 45 ranks built and installed in 1951, credits its tonal design to tonal director Jacob Schaefer.

Wicks built theatre instruments alongside its church work. The St. Louis Theatre Organ Society documents Opus 777 of 1927, a three-manual instrument of six ranks with toy counter, harp, xylophone and chimes, which went into the Granada Theatre in Greencastle, Indiana, in 1928. That is one documented instrument, and it says nothing about how many theatre organs the firm built; the broader statement is the company’s own grouping of ‘the Theater Organs of the same era’ with its church work of the 1930s and 1940s, and it comes from the builder.

Mortuary organs were a substantial share of the firm’s 1930s output. A 2004 history of the mortuary pipe organ in The Diapason states that Wicks became the preeminent builder in the American mortuary market by output and geographic reach, accounting for over half of the mortuary organs built by the five largest manufacturers, and that during the 1930s mortuary sales made up 25 percent or more of the firm’s total output. The same history names the graduated line of small standardized models Wicks marketed in the 1930s, from the two-rank Miniature to the four-rank Rhapsody. Those models are a product family with their own construction, described at Wicks Unit Chests and Small-Organ Models; here they are era evidence that a 1930s Wicks may be a small standard model rather than a custom church instrument.

Opus 3296 shows the scale of the firm’s church work in the decade before the change. St. Stephen’s Episcopal Church in Philadelphia records the instrument, dedicated on February 17, 1953, as approximately 59 stops and 38 ranks with 2,806 pipes, including a seven-rank floating echo division, played from a new detached roll-top console with drawknobs; it was contracted in May 1952 for $34,250 and reused part of the pipework of the church’s 1907 Haskell organ. Two things in that record matter for era reading. The stop count runs well ahead of the rank count, so the specification cannot be read as one rank per stop, and the pipework was partly inherited, so the instrument’s sound was never entirely of one builder or one decade.

The pressures the profile reports are low by the firm’s earlier standard: two inches, one and a half inches, one inch or lower, with voicing moved from closed-toe to open-toe. Those figures are as the 2005 profile gives them for the firm’s practice in the 1960s and 1970s, not measurements taken from any particular organ. The lower pressures needed their own regulators; the profile records that new regulators were developed to work at them, so the wind system changed along with the voicing it fed.

Low pressure did not become a rule for everything the firm built afterwards. The Neo-Victorian instrument at Kalamazoo, with tonal finishing completed in January 2005, carries a Subterranean Tuba on 20 inches of wind.

John E. Sperling is the name the documented record attaches to the neo-Baroque period and to the decades of Wicks work that followed it up to 2000. The 2005 profile in The Diapason records that he joined Wicks in 1957 as voicer and tonal finisher, became tonal director, is credited with the design and finishing of over 3,000 Wicks organs, and was named tonal director emeritus in October 2000, when William Hamner succeeded him. The credit for over 3,000 instruments is the profile’s figure. Before Sperling, the one earlier tonal director documented by name is Jacob Schaefer, credited with the tonal design of Opus 3140 of 1951.

How a specification comes about is described by the company itself. As of September 2026, the current Wicks website has the customer and a Wicks craftsman settle the design, finish, style, specification, price and every detail of the organ before the specification passes to the design department, where the layout and visual design are created, blueprints are drawn, the relay is laid out and wiring plans are made. That description covers only the front end of the process and says nothing about tonal finishing.

The company describes its instruments of the 1980s and 1990s as ‘American-Classic’, and that label is the company’s own rather than a trade-journal one. What the firm was doing in those years is illustrated by work on another builder’s organ. The Cathedral Basilica of Saint Louis records on its own organ page that in 1997 the Wicks Organ Company supplied a new four-manual sanctuary console, refurbished the gallery console, installed new solid-state circuitry throughout, added several ranks to bring the organ to 96, and fitted some digital stops, and that in 2007 Wicks built a new Cornet V for the dome division.

That instrument is a Kilgen organ rebuilt by M.P. Moller before Wicks touched it, and the cathedral’s account is its own undated chronology, so it documents what the firm did in 1997 rather than what a Wicks organ of the period contains; what it does show is solid-state control and digital stops inside the firm’s 1990s practice.

Opus 6419 at First Congregational Church, Kalamazoo, Michigan, is presented by a 2006 cover feature in The Diapason as the firm’s first ‘Neo-Victorian’ instrument: about 65 ranks, tonal finishing completed in January 2005, with a 32′ Double Trombone and a Subterranean Tuba on 20 inches of wind. Set beside the one-inch pressures of the neo-Baroque years, it marks the other end of the firm’s documented range, and it is the reason a style label cannot be read from the builder’s name alone.

The firm was still developing its pipe-making in the 1990s. United States patent 5,233,897, filed by Scott M. Wick on March 5, 1991, granted August 10, 1993 and assigned to the Wicks firm, discloses forming a reed-pipe shallot from solid cylindrical bar stock, with a tapered bore formed axially through the bar, one side planed flat, a slot cut through the planed side into the bore and an end plate soldered over the end; the patent says the earlier method of wrapping a trapezoidal sheet around a mandrel ‘requires considerable time and effort’ and that ‘the slot may be cut to different shapes depending on the desired sound to be produced by the shallot’.

A patent records what its applicant claimed, not what went into every reed the firm made afterwards, and this one lapsed in 2001 for non-payment of fees; it stands here as evidence that reed construction was still being worked on at Wicks in the years the company calls American-Classic.

During the neo-Baroque period Wicks was building approximately 100 organs a year, according to the 2005 profile. The early pace is stated by a public-history entry and by the company: a Southern Illinois University Edwardsville entry states that Wicks built 275 organs in its first thirteen years and that its opus list passed 1,000 during the following fifteen, and Wicks Organ LLC states on its own history page that ‘In the 15 years after inventing DIRECT-ELECTRIC action, the Wicks opus list grew to over 1000’. Neither statement fixes a calendar year for Opus 1000: the university entry supports only a rough early chronology, and the company statement is undated and depends on which invention date is assumed, a question that belongs to Wicks DIRECT-ELECTRIC Action: Meaning, Boundaries, and Comparison.

The documented series runs from Opus One, built in 1906 for St. Paul R.C. Church in Highland and, as of August 2026, still playing in museum space at the company’s premises, to Opus 6419 of 2005 at Kalamazoo.

There is no settled lifetime total for the firm’s output. The Wikipedia article on the firm gives ‘over 6,440 instruments installed mostly in the U.S.’, a trade-journal directory listing supplied by the firm gives ‘over 6466 organs’, and the two figures have not been reconciled against a factory opus list. Secondary accounts repeat the 6,440 figure: a 2019 parish dedication booklet restates it in wording that appears to follow the encyclopedia article, so the two are not independent. Treat any single total as the figure of the source that gives it, not as a count of what the firm built. Whether a published opus list exists is taken up at Wicks Factory Records and Opus Documentation.

A stop and a rank are not the same count, and the word stop is itself defined two ways. As of September 2026 the Wicks glossary defines a stop as an individual voice composed of one or more ranks of pipes, its name carrying a number such as 16 or 4 for its pitch according to the length of its largest pipe, and the Organ Historical Society glossary likewise places the word on the ranks activated by a single control; the American Guild of Organists glossary instead defines the stop as the knob or tablet that pulls a rank into play. Stop counts from different sources are therefore comparable only when the definition in use is stated, which is one reason the 59 stops and 38 ranks of Opus 3296 are not a contradiction.

A division is a section of the organ made up of one or more windchests with their pipes, played from one manual or pedal keyboard, whose ranks are made and voiced to be used together. The relationship to the keyboards is not always one to one: a floating division, such as the seven-rank echo of Opus 3296, has no keyboard of its own, and one division can be split across two chests.

A mutation is a rank sounding a pitch other than the note played or its octave, its footage written as a fraction such as 2 2/3 or 1 3/5; the fraction names the interval, not the tonal family, which may be principal-scaled or flute-scaled. A celeste is a rank tuned slightly off unison with a partner in the same division and meant to be drawn with that partner, so one stoplist line can need two ranks to be usable, another reason stop lines and rank counts diverge. The Swell is conventionally the enclosed manual division, its pipes standing in a wooden box with adjustable louvers or shades, and it typically carries the softer flues, strings and reeds; enclosure changes which resources can be used together.

Tuning slides bear on era reading only as a construction detail. The Wicks glossary describes them as cylindrical or conical extensions of the body of open pipes, made adjustable for tuning and fitting tightly enough not to move if undisturbed, and the entry is a definition rather than a chronology, so a slide is not era evidence on its own.

Three questions are worth separating before any work on a Wicks organ is planned, and each has its own page. Which period of the firm’s practice the instrument belongs to is the question answered here. When it was built is answered from opus, nameplate and record evidence at Identifying and Dating Wicks Organs, Companies, and Opus Suffixes, with the surviving paperwork discussed at Wicks Factory Records and Opus Documentation. What is still original inside it, and what that means for keeping or replacing the action, is answered at Preserving Versus Replacing Original Wicks Action. An era placement written into the project record beside those answers gives an inspection something to test against, because the pressures, voicing and switching the 2005 profile describes are physical characteristics that either match the instrument or do not.
