Arnoldo Sartorio, German composer, pianist, and teacher (d. 1936)
Arnold Gabriel Holland Sartorio (30 March 1853, in Frankfurt – 15 February 1936 in Krefeld) was a German composer, choral conductor, and piano teacher of the Romantic period. His musical output lay almost entirely in the genre of salon music pioneered by Sigismond Thalberg among others and transcended by Frédéric Chopin and Franz Liszt.

Exceptionally prolific, Sartorio composed works for over 1,200 opus numbers, his reaching of Opus 1,000 being documented in the magazine The Etude. While virtually unknown today, he was remembered by past audiences chiefly for pedagogical pieces written for his piano students to play. Many of these were issued under pseudonyms, which include Felix Durand, T. Devrient, Arthur Dana, Carlotta Bocca, Christian Schäfer, and Victor Abelle.
