Hook & Hastings Organs
The right resource depends on which decision you are facing: which of the three successive Hook firm styles your instrument belongs to, where any surviving record of it might be found, or what in it is original and what a stewardship decision should protect. Those three questions share one piece of orientation. The Diapason describes the firm as operating under three principal names, E. & G. G. Hook, E. & G. G. Hook & Hastings, and Hook & Hastings Company, and the Peabody Essex Museum’s finding aid describes the same continuous business, founded by Elias and George Greenleaf Hook and later enlarged to include Francis H. Hastings, with manufacturing at Kendal Green in Massachusetts by the 1890s. The names are eras of one firm, not three companies.
Published sources disagree about the years at which one name gave way to the next, about when the firm began and ended, and about how long it operated. Every date in this part of the site is therefore given as the position of the source that states it, and no date is treated as settled. Three pages beneath this one each answer a single decision in full; the choices are set out just after the era vocabulary, before any history, so you can go straight to the one that fits.
Which Hook firm built your organ
Start by placing the instrument in an era. The three styles follow one another in time, and the style in use when an organ was built is the name that belongs to it. Fixing that era for a particular instrument is the job of the identification page; what follows is the vocabulary you need to use it.
The founding partnership: E. & G. G. Hook
E. & G. G. Hook is the style of the founding partnership of the brothers Elias and George Greenleaf Hook, and it belongs to the firm’s earliest instruments. The Peabody Essex Museum’s finding aid and The Diapason give different founding years, and this page does not choose between them. For orientation, an instrument built before Francis H. Hastings was named in the firm style is an E. & G. G. Hook organ, and the earlier style is not a shorthand for the enlarged one that followed it.
The enlarged partnership: E. & G. G. Hook & Hastings
E. & G. G. Hook & Hastings is the style of the enlarged partnership. The Peabody Essex Museum’s finding aid records that Francis H. Hastings joined the firm, later became a partner, and that the firm thereafter operated as E. & G.G. Hook & Hastings; The Diapason gives the same style for the firm’s middle era. The year Hastings entered the firm, the year he became a partner, and the year the enlarged style came into use are each stated differently by different publications, and the identification page sets those positions side by side. The enlarged partnership style and the later company style name different eras of the same firm, so neither is a shorthand for the other.
The later company: Hook & Hastings Company
Hook & Hastings Company is the style The Diapason attaches to the firm’s final decades. The Peabody Essex Museum’s finding aid places the company’s offices in Boston, New York, and Philadelphia by the 1890s, with manufacturing at Kendal Green. The Weston Historical Society, in a local summary without footnotes, dates the completion of the Kendal Green factory’s center section and west wing to 1887 and its east wing to 1889, and states that the firm made all parts of its organs except the keys. The founding style and the company style are separated by the whole partnership era, so an instrument’s era decides which of the three names it carries.
Start with the question you actually have
Choose the guide that matches your question.
What should I call it, and when was it built?
Go to identifying and dating a Hook or Hook & Hastings organ. Compare the evidence for names and dates: every competing published position for the firm’s milestones, with the institution or publication that states it, and how a nameplate, an opus number, a database label, or a parish tradition bears on the name form and build date of one instrument. Use it when the question is what to write on a plaque, in a grant application, or in a database entry, or when two sources give your organ two different dates.
Where are the records, the opus entry, or any documentation?
Go to Hook & Hastings records, opus lists, and documentation. That page covers what Hook material survives and in whose custody, how each surviving finding tool is keyed and bounded, how to reach a repository or a published copy, and what a negative search result does and does not establish for this firm. Use it when you need an opus entry, a contract or specification, a photograph, or evidence for a research request.
What is original, what has changed, and what should we do about it?
Go to Hook tracker construction, alterations, and restoration. That page covers the key action, wind system, chest, and casework evidence specific to Hook instruments, the categories of later alteration documented on them, what evidence supports retaining or reconstructing original fabric, and what recognition programs mean for a stewardship decision. It explains mechanisms and evidence; it does not give service procedures and does not diagnose a particular instrument at a distance.
For builders other than the Hook firms, return to the organ builders hub.
Why dates and attributions in Hook sources disagree
Because otherwise credible sources start and end the firm’s story in different years. The Diapason, the Peabody Essex Museum’s finding aid, and the Organ Historical Society each give the firm a chronology, and between them those chronologies differ on the founding year, on when the Hastings name entered the firm style, and on when the firm ended. A confident single date found elsewhere is one publication’s position, not a settled fact.
The headline output figure shows the same pattern. The Diapason, the Weston Historical Society, and the Organ Historical Society’s catalog description of the published Hook opus list all repeat a total of 2,614 organs, yet each attaches a different number of operating years to it, because each starts and ends the firm in different years; the Weston Historical Society calls the total an estimate. The figure is stable because it appears to derive from the same published opus list, so it is best read as the widely repeated published total rather than an independently verified count.
Attribution labels vary as well. The Organ Historical Society’s Historic Organ Citations table, for example, lists instruments attributed to the Hook firms under each of the three styles, and several of its rows carry no build date at all. A label in a third-party list is that list’s attribution and needs to be checked against the instrument’s own evidence, which is the work of the identification page.
What survives, and where recognition fits
The Organ Historical Society’s introduction to the firm characterizes the firm’s own official records as not having survived. That characterization is not the whole picture, because institutional collections holding company record material do exist; the Society’s statement is best read as meaning that the main body of shop records did not survive as a single archive. What survives, in whose custody, how each piece is keyed, and the date the Society’s statement carries are the subject of the records and documentation page.
An old Hook organ is not necessarily an unaltered one. Andover Organ Company’s own account of its work on one large instrument from the 1870s records that the organ had been electrified in the 1920s and was later reworked again, with its keyboard compass extended and pipework from other Hook organs added. Which changes a Hook instrument commonly carries, and what evidence supports retaining or reconstructing original fabric, is the subject of the construction, alterations, and restoration page.
Recognition programs do cover this firm. As of September 2, 2026, the Organ Historical Society’s Historic Organ Citations table listed at least sixteen instruments attributed to the Hook firms, though those entries are a sample of the table and not a census, and the Society states that the citations program has since been replaced by its Historic Pipe Organ Registry. The two are separate programs and third parties name them inconsistently: a citation is not a registry entry, and either records a judgment at the date of award, not evidence of an instrument’s current condition. What recognition means for a stewardship decision is explained on the construction, alterations, and restoration page.
Whichever question you start with, the answer rests on what can be documented. Because published dates and third-party labels disagree, and because later work can change an instrument materially, the records kept by the church itself and a written account of what is actually present in the instrument now carry more weight than any single published date. Both belong at the start of project planning, before a name goes on a plaque, a research request is written, or a scope of work is discussed.
Frequently Asked Questions
This firm used three successive names, and your organ should carry the one in use when it was built. They were E. & G. G. Hook, then E. & G. G. Hook & Hastings, then Hook & Hastings Company, in that order; The Diapason and the Peabody Essex Museum’s finding aid both describe them as successive styles of one continuous firm rather than three companies. The years at which one style gave way to the next are contested between published sources and are not stated here; the identification page sets out each published position with its attribution and works through what your instrument’s own evidence supports.
In Boston, and later at a factory at Kendal Green in Weston, Massachusetts; the Weston Historical Society describes the firm as operating in Boston and Weston. The Peabody Essex Museum’s finding aid places manufacturing at Kendal Green by the 1890s, with offices in Boston, New York, and Philadelphia. The Weston Historical Society, in a local summary without footnotes, dates the factory’s center section and west wing to 1887 and its east wing to 1889, describes a building with an 80-foot-wide center section and two 100-foot wings, and records 70 employees in 1906, a single-year figure.
2,614 is the widely repeated published total, and it appears to derive from the published Hook opus list rather than from an independent count; the Weston Historical Society gives it as an estimate. The published sources that repeat that total attach different operating spans to it, because the founding and closing years of the firm are themselves unresolved between sources; the identification page sets out each published position with its attribution.
The Organ Historical Society runs recognition programs that list Hook instruments, but they are recognition awards rather than a census of surviving organs. As of September 2, 2026, the Society’s Historic Organ Citations table listed at least sixteen instruments attributed to the Hook firms, a sample of the table rather than a census, and the Society states that the citations program has been replaced by its Historic Pipe Organ Registry; a citation is not a registry entry. Either records a judgment at the date of award and is not evidence of an instrument’s current condition. What recognition does and does not mean for a stewardship decision is explained on the construction, alterations, and restoration page.
