Curtis Organ, Pipe organ in Irvine Auditorium, Philadelphia, United States.
The Curtis Organ features 162 ranks containing 10,731 pipes ranging from pencil diameter to 32 feet across, creating orchestral sounds throughout the Gothic auditorium.
Originally manufactured by Austin Organ Company as Opus 1416 in 1926 for the Philadelphia Sesquicentennial Exposition, the organ was later acquired and donated to the University of Pennsylvania.
Named after publisher Cyrus H.K. Curtis, the organ serves as a centerpiece for university ceremonies, guest recitals, and annual Halloween performances of silent films.
The organ underwent comprehensive restoration in the early 2000s with a new mahogany console featuring computerized touchscreen controls and recording capabilities for enhanced performance versatility.
When connected to its MIDI interface, the Curtis Organ became the world's largest MIDI-capable instrument, combining traditional craftsmanship with modern digital technology.
