Some of our entries are names that might never appear on a nameplate or nameboard.
On the other hand, there are both individuals and firms who are responsible for conserving historic organs through location, or preserving the usefulness of pipe organs through rebuilding or making modifications to existing instruments. In these cases, we are proud to acknowledge their contributions to the ongoing artistic tradition of the pipe organ in America through individual entries in our online database.
