Saint Michael's Organ from Rudolf von Beckerath Organ Company
From a pamphlet available in the narthex (entrance) of the church, “A Brief Tour and Description of St. Michael’s Church Interior and Windows,” by church Archivist Jean Ballard Terepka:
“The church houses two fine tracker-action organs, a smaller one in The Chapel of the Angels, and one in the north gallery (shown here), both built by the Rudolf von Beckerath Organ Company (Hamburg, Germany) in 1967. The main organ is an eclectic instrument, at home with music of all periods, but a particularly fine exponent of both German Baroque and French Classic music. The instrument has three manuals and petal with 38 stops, totaling 55 ranks. The case rises 31 feet from the rear gallery floor, with the Ruckpositiv in a separate case mounted on the gallery rail. The Beckerath firm completely cleaned and overhauled the organ during the fall 1995, but no tonal changes were made. Now in mint condition, it remains an important and successful example of the “Orgelbewegung” movement, and is considered by many, one of the most important instruments in the city of New York. These organs, together with the fine acrostics of the church building, feature prominently in choral and organ concerts throughout the season.”
The Beckerath website has photos of their organs and an interesting history of the company.
