The 1913 pipe organ was built by Murray Harris, one of the nation's most important organ builders.
Harris built the largest organ in the world for the St. Louis Exhibition.
The Artemesia organ is the largest remaining example of Harris's work.
The Artemesia organ is massive, with three manuals, main and echo pipe chambers, a player mechanism that operates from punched paper rolls.
Sound emanates from literally hundreds of pipes and chimes on all three levels.
Large chambers were built throughout the house to house the blowers, relays, and other mechanisms.
The current replacement value of the Artemesia organ, without considering its historical significance, is estimated at 1.1 million dollars.
