instrument built by Möller. As a true theater organ, as opposed to a church organ, Mighty Mo boasts pipes that range in size from 32 feet (nearly 10 meters) tall to the size of a small ballpoint pen, and is designed to imitate the sounds of a full orchestra. Besides the pipes, it also contains a marimba, xylophone, glockenspiel, drums, sleigh bells, a gong, and even a six-foot (1.8m) grand piano (originally from the Kilgen organ in Chicago's Piccadilly Theatre); plus a large variety of silent movie sound effects (such as various car horns, thunder and rain effects, bird whistles, etc.). The organ is remarkable for a theater organ because it also includes 12 ranks of pipes for a church organ, known as the "Ethereal" division. Thus the organ can be played as a church organ as well as a theater organ. It is noteworthy that the Mighty Mo is among the shrinking list of instruments which remain installed in the theaters for which they were designed. Larry Douglas Embury was the theater's permanent Organist in Residence from 2002 until his death in February 2016. In that capacity he presided over the Mighty Mo in performances during the Fox's summer film festival and the Atlanta Ballet's annual production of The Nutcracker. In September 2002, he hosted "Fox at the Fox," a concert commemorating the twenty-second anniversary of the death of the great concert organist, Virgil Fox. Fox had played a famous series of "Fox at the Fox" concerts on the Mighty Mo at the Fox Theatre in the 1970s. Private residence The Fox also contains a apartment that served as the private residence of Joe Patten, who served as technical director from 1974 to 2004. Patten, who was born in 1927, and died on April 7, 2016, was granted a lifetime rent-free lease to the apartment. Patten first became involved with the Fox when he volunteered to restore the theater's Moller pipe organ. He later was instrumental in the movement to save the Fox from demolition. The apartment occupies space previously used as an office by the Shriners, who had built the Fox as a meeting hall. The apartment's walls are 2 to thick, and a passageway leads from the bedroom to a former spotlight platform at the top of the auditorium. A separate entrance provides direct access to the street outside the theater. Patten's presence is credited with having
