What Does OHS Mean in Pipe Organ History and What Does the Organ Historical Society Do?

In the pipe organ world, OHS stands for the Organ Historical Society, a nonprofit organization dedicated to celebrating, preserving, and studying the pipe organ in America across all its historic styles. It pursues that mission through research, education, advocacy, and music. If you are trying to understand who documents and advocates for American pipe organs, or you want to know where to find records and publications about them, OHS is the central institution to know.

What the Organ Historical Society Is

The Organ Historical Society is a membership-based organization focused specifically on the pipe organ in America. Its stated purpose covers four connected areas:

• Research — studying instruments, builders, and the contexts in which organs were made and used.
• Education — sharing that knowledge with members, organists, scholars, and the public.
• Advocacy — arguing for the value and survival of historic instruments.
• Music — supporting the repertoire and performance tradition that gives organs their purpose.

The scope is deliberately broad: the Society describes its interest as covering the pipe organ "in all its historic styles," not one era or one builder.

What OHS Actually Does

Publications

OHS publishes books on American organ history. One current example is Lost Pipe Organs of America by Rollin Smith, which documents instruments from the "Golden Age" of American organbuilding that no longer exist. According to the Society's description, the book covers organs in worship spaces but also in concert halls, auditoriums, universities, hotels, world's fairs, and expositions — including instruments at the 1869 Boston National Peace Jubilee, New York's Chickering, Mendelssohn, and Carnegie Halls, the Hotel Astor and Waldorf-Astoria, the 1883 Southern Exposition in Louisville, Chicago's Steinway Hall and Stadium, the 1915 Panama-Pacific Exposition's Festival Hall, and Lincoln Center's Philharmonic Hall. Builders covered include Hook, Jardine, Roosevelt, Skinner, Farrand & Votey, Aeolian, Möller, Austin, Estey, Barton, Wurlitzer, and Aeolian-Skinner.

The Pipe Organ Database

The Society maintains a Pipe Organ Database, a searchable resource for locating and identifying instruments. If you want to research a specific organ, builder, or location, this is the entry point the Society itself points to.

National Conventions

OHS holds national conventions that combine performances, instrument visits, and scholarship. Two are highlighted in the Society's current news:

The 2026 Philadelphia convention is framed as a double celebration: the United States Semiquincentennial and the Society's own Platinum Jubilee. The instruments listed for that event span builders and dates from Aeolian (1930) and Aeolian-Skinner (1931, 1933, 1937) through Austin (1961), M.P. Möller (1950), Reuter (2000), Rieger (2005), Dobson (2006 and 2026), Kegg (2014), and C.B. Fisk (2018) — a range that illustrates the Society's cross-era approach.

Grants and Funds

OHS administers named programs that support its mission, including the Dr. Rollin Smith Research Grant and the Barbara Owen Fund for Education. These exist to fund research and educational work in the field.

Calendar and Membership Materials

The Society produces a Pipe Organ Calendar and maintains a current-month events listing, which serve members and the wider organ community.

How to Use OHS as a Resource

If your goal is to research an American pipe organ, the practical path is:

1. Start with the Pipe Organ Database to see whether the instrument or builder is already documented.
2. Check OHS publications for historical context, especially for instruments that have been lost or altered.
3. Watch for national convention announcements if you want to hear and see instruments in person; the 2026 Philadelphia and 2027 Boston events are the current reference points.
4. Look into grants and funds if you are conducting research or educational work that fits the Society's mission.

What OHS Is Not

OHS is not a generic abbreviation for pipe organs, and it is not a builder or a venue. It is specifically the Organ Historical Society — the organization that documents, studies, and advocates for the American pipe organ tradition. Confusing it with a technical term or a manufacturer will send you to the wrong sources.

For anyone asking who keeps the record of American pipe organs and why it matters, the answer is the Organ Historical Society, and its database, publications, and conventions are the concrete ways that record is kept.
