OHS 2026 - Philadelphia
OHS 2026
Philadelphia is the site of great celebration in 2026 — not the least of which because it marks the 250th anniversary of the signing of the Declaration of Independence, also known as the United States Semiquincentennial. This year-long celebration taking place across the country is a time to reflect on the contributions made by millions of citizens in order to form a more perfect union. This year also marks the 70th anniversary of the founding of the Organ Historical Society. A Septuagennial or Platinum Jubilee represents a significant milestone in the life of this totally unique institution. And what better way to celebrate than with a party!
Edoardo Bellotti plays the Italian organ at the Memorial Art Gallery, during the 2018 Rochester convention.
Our Conventions
The Organ Historical Society celebrates the pipe organ each year through a convention featuring instruments of historical interest in one location in North America. The pipe organ community gathers at these conventions for fellowship, recitals, lectures, and to sample the local culture and architecture. In many instances, the work of a local organbuilder (recent or historical) is highlighted. Non-members are very welcome to attend, although members receive a significant discount on registration, so we encourage attendees to join. The E. Power Biggs Scholarship can provide funding for first-time attendees of OHS conventions.
Host a Convention
Are you proud of the historic pipe organs in your area? Would you like to share them with the rest of the OHS membership?
The Organ Historical Society is seeking proposals to host conventions in the future, and we would love to come visit! If you’ve ever wanted to show off the organs in your area to the rest of the OHS membership, this is a great opportunity. As a first step, please contact the CEO, Ed McCall to start a conversation about the possibility of hosting. After this, an initial proposal will need to have a preliminary list of organs to visit and a preliminary itinerary, as well as a list of people who would be willing to serve on a convention committee. For complete information on hosting a convention, please download the convention guidelines here:
