Though she has worked with a number of pipe organ builders, Morgan’s association with C.B. Fisk, Inc. has spanned almost five decades. Fisk organs are known for harmonizing visually as well as tonally with with the architecture and acoustics of their resident spaces. Similarly, Morgan’s designs are carefully developed to enhance each particular instrument’s casework. Morgan’s patron and mentor, the late Charles Fisk, preeminent American pipe organ builder, insisted that sculpture for the facades of his instruments be original works of art, not simply ornamentation. This principle has guided her in her designs for pipe organ cases and for other architectural contexts.
