Wilhelm Middelschulte (April 3, 1863, Werve, Kreis Hamm, now part of Kamen – May 4, 1943, Dortmund) was a German organist and composer who resided in America for most of his career.
He later attended the Royal Academic Institute for Church Music [de], where he studied organ and theory with August Haupt.
After briefly holding a position at the Royal Institute and acquiring a post at the St. Luke Church [de] in Berlin, he moved to Chicago in 1891.
Fox frequently used as an encore to his performances Middelschulte's "Perpetuum Mobile", an elaborate piece that builds from a subdued sound to, by the end, fortissimo and played almost entirely on the pedals; the penultimate measure contains an ascending scalar flourish and the last measure a single chord, both played on full organ.
Ferruccio Busoni's Fantasia contrappuntistica was dedicated to "Wilhelm Middelschulte, Meister der Kontrapunkte".
