  • Church previously had 1849, then 1867 Hall & Labagh organs. Rebuilt by H. L. Roosevelt 1881. Then 1902 Austin Op. 62. Also 1926 West End organ by Midmer-Losh, which was removed within a few short years, with much of the pipework going into the Aeolian-Skinner organ at the residence of Senator Emerson Richards in Atlantic City, NJ. (OHS PC Database. October 30, 2004)
  • G. Donald Harrison design. String division built 1922 for previous Austin by Wanamaker shop. New Austin console in 1965. (OHS PC Database. October 30, 2004)
  • Cornel Zimmer added a West End organ in 2002 made up of digital and pipe stops; it was to be removed ca.2018 and replaced with vintage Aeolian-Skinner pipework making up a replacement West End organ by Foley-Baker; as part of the general organ project, the Emery Brothers will take on the historic renovation of the Chancel Organ. (Jeff Scofield. October 5, 2018)
  • Updated through information adapted from E. M. Skinner/Aeolian-Skinner Opus List, by Sand Lawn and Allen Kinzey (Organ Historical Society, 1997), and included here through the kind permission of Sand Lawn:
    Included String division with Wanamaker pipework and Lady Chapel division with Welte pipework; dedicated in 1937; extant; unaltered; new console by Austin in 1966; old console moved to Covenant Presbyterian, Albany, Georgia; [0HS Plaque] (Database Manager. February 10, 2007)
  • Updated by Robert Vogel, listing this web site as a source of information:

    (Stephen Hall. April 18, 2019)
  • Updated by Ray Biswanger, who has heard or played the organ. The console is in a loft below the main instrument. The String Organ chest is of the Fleming design, built by the Wanamaker Organ Shop, with Kimball pipework. The Screen Organ is by Austin (Carlton Michell (1902) and the contract stated it was to be "a replica of the famous 16th-century work in England." Its backward-looking design preceded the Organ Reform movement by several decades. The predecessor Austin is covered in Orpha Ochse's Austin book. The Wanamaker Shop had a Welte chest built for this pipework, replacing the original Austin Chest. G. Donald Harrison remade the 4' Lieblich Flote into a Nazard. The pipework of the Screen Organ, however, remains Austin. [This was covered in detail in my own book, "Music in the Marketplace."] I took lessons on this organ and was a parishioner there for almost 30 years. During Wesley A. Day's tenure as parish organist, in the late '50s or early '60s, the central tower was removed and carved panels were produced at some expense to open the main case and let the tone out. This tower (pieces from which were kept in the undercroft) was subsequently returned during the Zimmer enlargement. Some of the Richards/Midmer-Losh West End organ went to First Baptist Church, 1373 Grant Street, Denver, Colorado, as another Database entry duly notes. (Thurlow Weed. July 24, 2019)
