The Skinner organ at St. Luke’s Church in Evanston, Illinois, Ernest M. Skinner’s “Opus [work] 327,” is both magnificent and exceedingly rare. Fully restored in the 1990s, Opus 327 is today one of a very few close-to-original Skinner organs left in the United States, a rare surviving example of Skinner’s artistic and engineering genius.

The organ and its acoustic space are inseparable. The St. Luke’s nave, or central worship space, is itself a powerful musical instrument. The Gothic-style building was begun in 1906 to the designs of John Sutcliffe and erected in several stages. In 1914, the nave was completed to a height of seventy feet. Construction halted after the 1929 stock market crash and never resumed.

In 1922, the Skinner Organ Company of Boston, Massachusetts, installed its Opus 327, a four-manual organ. The organ is in chambers to the right (south) of the chancel area. The Choir and Pedal divisions have the lowest position; the Great and Solo are above; the Swell division is at the top. The main façade, facing the chancel, includes some speaking pipes. A smaller façade in the south aisle is composed of dummy pipes. In 1959, the Aeolian-Skinner Organ Company installed the Fanfare Trumpet above the west doors of the nave.

Opus 327 was built to mimic the sounds of a full orchestra. The organ’s console, to the left (north) of the chancel, allows the musician to create sound using “a sophisticated electro-pneumatic computer” that Ernest M. Skinner invented and perfected. The voice of each of its thousands of metal and wooden pipes (see the specifications) is controlled by air that enters a leather pouch through a valve. The pipes sit in “windchests” that receive air from reservoirs that must be kept at optimal pressure and humidity. A motor forces air into the reservoirs through a blower in the church’s lower level.


In 2012, a not-for-profit organization was formed with a mission to preserve the Opus 327 organ, to bring live musical performances to a broad audience, and to provide musical education to the community.
