Aeolian-Skinner installed this small organ in the church's original chapel, since converted for another use. The entire organ, except for the Diapason, was enclosed in one swell box. Known as the William C. Carl Memorial Organ, funding was provided by gifls of the friends, graduates and pupils of the late Dr. Carl, who served as organist and choirmaster from 1892-1936, and who founded the Guilmant Organ School, which was located at First Presbyterian Church. This organ was removed in 1961 when the Austin organ was installed in the Sanctuary.
